  1. A bit of an update on my PID kit that I've recently been working on. Whilst I'm keeping the current kit alive and kicking, and the full details of it are still here: http://coffeeforums.co.uk/showthread.php?27931-MrShades-Gaggia-Classic-PID-Kit-Complete-PID-kit-with-full-guide-%A389 I've also been working on a kit that uses a PID controller that looks almost identical to the Auber one. It's 1/32DIN (rather than 1/16DIN for the Rex C100) and therefore half the size. It's half the size as it only has one display (rather than the two displays on the 1/16DIN Rex C100). It's obviously much smaller, and this kit comes with a new aluminium box - that is also a two-part box (Auber seem to use an extruded single piece box, which you can't simply assemble around the controller once you've wired it up). As with the other kit, there's a cut-out in the front (around 44mm x 22mm) and a rubber grommeted hole in the rear. As with the normal kit, all the SSRs and wires and everything else come with it - and they're all the same as the original kit. Hence there's now two options: 1. The original 1/16 DIN kit, with dual display - being a larger unit, with larger enclosure 2. This new 1/32 DIN kit, with single (dual purpose) display - being a smaller unit, with smaller enclosure As with everything, when it's smaller it's also more expensive (which is true for the PID controller and the aluminium enclosure) so this 1/32 DIN version is £5 more than the 1/16 DIN version - so it's £94 shipped to the UK. Any questions, please just ask - and I have these in stock now and if you'd like one then please just PM me. Some pics of the kit and controller: (It was cold in the workshop, and hadn't warmed up - so it's showing 14C. Obviously normally it would show the brew temp at around 93C) A couple of pics to allow you to see the difference between the 1/16 DIN (larger, dual display) and 1/32 DIN (this one, smaller and single display) versions: (Other than the fact that it doesn't say "Auber" on the front, if you can see any difference between this PID and the Auber one then let me know!) For the avoidance of doubt, and to prevent any questions - Whilst this 1/32DIN controller LOOKS like the Auber one, and many (if not all) the menu options are the same - it does NOT have the hidden Auber menus, and it does NOT provide preinfusion or any of the fancy Auber only functions. It provides materially the same functionality as the Rex C100 and controls brew and steam temp. I hope you like it! Many thanks, MrShades
  2. Hey All, Purchased my first machine last weekend from a member on this forum. So far I love it! Machine is really easy to use, bottomless portfilter allows me to see all my mistakes (I have made a lot of mistakes) Looking to buy a grinder (Sage Smart Pro) off another member on here. Thank you all for helping in my journey. Cheers, John
  3. Hi All, Recently purchased a Gaggia Classic With mr Shades PID from a Forum member and all is great. I have been using it for around a week now with no problems. Just gone to make a latte, Poured a nice shot, flicked the steam button looked at the PID controller no change in temperature. I have taken off the top lid, tested the back right SSR (labeled Steam) on pins 3 -4 (input) there is no voltage when the steam button is OFF, 230Vac When Switch is ON. Any ideas why this thing is not goign to the 137 Degrees it should do?
  4. Hey All, After this mornings events of driving up and down the motorway to perform a smooth exchange from a fellow forum member. I now have a grinder! Spent the last half an hour running beans through trying to get the correct grind setting and weight. Job Complete! I think i have now "finsihed" my first set up. Time to play around and learn from it. Thank you for all the help! Below are some images of Coffee Corner =D John Edit - Spelling
  5. Hi all, The Ecm Technika IV profi heat exchanger and rotary pump machine seems to be getting an upgrade at the end of the month. The New Ecm Technika V will have a PID among other upgrades. https://www.ecm.de/en/products/details/product/Product/Details/technika-iv-profi/ Now that the Technika V has been announced the Technika IV profi seems to be on sale. The machine is coming on 5 years after first production I think. I can score a new Technika IV on sale for a very good price. My question would be if should I get the older version Technika IV or get a newer released version. I don't know what internal parts have changed but the boiler seems to the same stainless steel boiler in both of the machines. I am interested in the Technika since it can be plumbed in. Any buying advice greatly appreciated. Thanks, Simon.
  6. Hi, just want to get an idea of what I should be getting for my machine. Gaggia Classic (original Italian model with 1425w boiler) Rancilio steam wand upgrade Bottomless portafilter 14g and 21g baskets Brass Plate IMS screen Mr Shades PID fitted? Original post when I purchased it. ive owned this about 2 years. never given me any problems. Only used Tesco ashbeck water. https://coffeeforums.co.uk/showthread.php?37143-Gaggia-Classic-2004-fully-rebuilt-with-new-seals-1425w&p=483746#post483746
  7. ... wondering how much i should sell my pre-philips gaggia classic for? Comes with - Rancilio steam wand - flat basket and originals (various sizes) - cleaning basket - OPV Pressure @ 10bar (comes with pressure gauge) - PID (with manual) - bottle of cafiza cleaning stuff - espresso measuring cup - sage milk jug with temperature strip Regularly descaled and cleaned. Basically it's everything you need to get making good coffee. I totally understand that you never get back what you put in but i'm curious as to how much you would put on bit and pieces i'm including. Cheers Rob
  8. A while ago (OK, I started this project about 12 months ago) I decided that there were probably folk in the UK who owned Gaggia Classics and wanted to PID them but were probably a bit daunted by the task. Whilst you CAN purchase all of the parts on eBay, and buy cable and connectors and all of the tools required to make everything - I know (from doing it myself) that it all soon adds up and it's not simple. Many people don't really know what to buy, where to source it and don't already have the tools needed to make the wires up etc. - and are therefore swayed towards the only "complete kit" for doing this easily, that being the Auber one. However, it's hellishly expensive as you can only purchase them from the US, with expensive shipping and then duty/VAT on top. So - I decided to make a similar (perhaps better) kit myself, largely from off-the-shelf parts but combined with the popular PID components that I also sell separately (the Pt100 sensors and the aluminium boxes). I put the outline kit together last Christmas, and started producing the manual - which I think is pretty much a complete Dummy's Guide to Install and Use - and now runs to some 59 pages of A4 (downloaded as a PDF), with lots and lots of photos, instructions, tips, etc. all the way through. The manual is finished off with a reference section for the PID. Throughout 2015 I've had a few people contact me, who have heard via the grapevine about my kit - and a few members on here have purchased the kit, installed it (sometimes with some PM/email assistance/support from me) and they've provided some great feedback on the manual, and hence it's gradually improved over the year to the point that I've not changed it for a while (currently on V4) and am now very happy with it. So - my original intention a year ago was to make a similar kit to the Auber one, but make it available in the UK at a reasonable price and with a better manual, and (I think) a better Pt100 sensor and a better aluminium box. Personally, I think I've done it.... ;-) Hence I can now launch the "MrShades Gaggia Classic PID Kit". It contains: - Rex C100 PID - with SSR output and all pins connected (including the important 6 and 7 for alarm/steam) - MrShades Pt100 sensor - MrShades aluminium enclosure with mounting tape (this used to be optional, but I've decided to make it part of the main kit) - Brew kit: ---- All wires, premade to required length and preterminated with connectors ---- SSR 40A DA with mounting screws - Steam kit: ---- All wires, premade to required length and preterminated with connectors ---- SSR 40A AA with mounting screws - Ancillary bits: ---- Cable ties ---- Thermal paste (for SSRs and Pt100 if desired) ---- earthing wire for enclosure ---- Spiral wire wrap You can see a photo of the main contents, ready to go, here: ...and all boxed up ready to go out to the next lucky owner (this one is yours @condor87 ): (The piece of paper isn't there just for the heck of it and to promote the kit, it contains the download instructions for the manual) As I mentioned, I've spent a great deal of time and effort producing the manual - and I'm not making in publicly available as I believe that a significant part of the value in this kit is the knowledge and information within the manual. Hence I'm not posting the full manual here, but am posting a preview of the first few pages so that you can see the contents and the quality (hopefully). This sample is a LOW RES PDF and has low-res photos, the final version is 59 pages and has higher quality photos throughout. Take a look at the manual sample here. (Note that this is truly AWFUL quality, the fonts are everywhere and the quality is awful - the proper version is very much nicer!) I've priced this marginally above my production costs (especially when taking into account the time and effort that goes into making it up) and want to sell it mainly to help Gaggia Classic owners who perhaps feel daunted by the DIY route, not being sure what to buy or what to do with it, or just want an easy-to-fit PID kit. Obviously anyone who buys it gets my PM/email support if required (and for what it's worth!). Price : £89 inc UK shipping. Drop me a PM if you're interested or have any further questions. MrShades *** UPDATE: *** This "1/16DIN, dual display" version of the kit will remain available, as above - though I've now launched an additional version of the kit that uses a 1/32DIN single-display controller. Full details of it are available here: http://coffeeforums.co.uk/showthread.php?31342-MrShades-Gaggia-Classic-PID-Kit-%281-32DIN%29-Complete-PID-kit-with-full-guide-%A394&p=417906#post417906 *** UPDATE ***. I've now changed the case for this kit - to a smooth finish silver case, and whilst I think it looks better and remains a "clam shell" design (so it splits apart) the new case has JUST enough room inside it to mount the PID controller in either orientation- so that case can be horizontally or vertically mounted on the Classic. I've put some other pics later on this thread but here's a couple to show the new case:
  9. Thought I'd share my restoration project here to maybe inspire some others as well as to get some pointers from Gaggia veterans! I wasn't satisfied with my old Breville BES830XL machine and some searching led me to either the Gaggia Classic or the Rancilio Silvia. After watching a couple of teardown videos on the classic and seeing how mechanically simple the machine was, it was the route I decided to take. I found a used Classic from the late 90's for sale and began the project. To say it wasn't well maintained would be a serious understatement! I forgot to take a pic of the machine prior to tearing it apart, but the gold coating on the case was in pretty rough shape and while it seems some folks like the gold look of the older models, it wasn't my cup of tea! Got the machine torn apart here. The bolts holding the boiler to the group head were seized quite badly. Had to use a torch to try and expand the brass on the group head and then I was able to thread out the bolts with some vice grips attached to them. Here's everything laid out and organized so I don't lose track of things As you can see, the boiler and group head were in pretty rough shape. All metal parts ( boiler, group head, OPV, solenoid valve, etc.) got a nice soak in a citric acid bath and I hand sanded the surface of the boiler down to get rid of the pitting. A little more sanding with some 150, 400 and 800 grit and I got the boiler face cleaned up pretty nice. I also did a bunch of hand sanding inside the boiler I ordered up an ebay gasket set and and got everything back together. Now onto the case. I stripped it down to the bare metal and was contemplating leaving it like this, but there was just too much pitting on the front and in the bottom where the water reservoir and drip tray sit. Painted it a "stainless steel" tremclad colour. Turned out alright. We'll see how it holds up over time. Now onto the next phase. Adding a PID controller. I didn't like the look of the external boxes everyone is using, so I decided to use a small arduino + SSR setup and will keep all of the components inside other than a small OLED screen that will sit outside the case. Here's a shot of the boiler with a thermocouple with M4 threads that screwed into the old coffee thermostat location. Testing out the solid state relay with an arduino board I had already made up for another project. This is what the current arduino board looks like. It's not the final state either, but it's much smaller. As is stands right now, I've got the machine up and running and have been using it daily for about a week and it's been running great. I need to finished up the arduino bit and get it all mounted inside. The PID control is working quite well. I also ordered up a bottomless portafilter from ebay and splurged on a nice VST 18 gram basket. Additional things I have planned. Not all of them are high priority: Create multiple pages for the OLED display and cycle through them Read the status of the steam switch to crank up the boiler setpoint for the steam wand. Either add an analog pressure gauge to the front of the machine or use a pressure transducer and use the MCU and OLED to display it Read the status of the brew switch so that the OLED displays a second timer to time the shots Add a second SSR to PWM control the water pump to add a pre-infusion stage The code running on the arduino is here. I'll keep the thread updated as things progress.
  10. I recently found that the KitchenAid Artisan espresso machines used mainly Gaggia Classic parts inside and that they were dual boiler so I managed to pick one up from Ebay at £41 in a nice fetching "Medallion Silver" finish. It would be a great starting point for a project. I did have in mind re-casing the whole project but the KA casing is in fantastic condition and does look a lot better on the counter-top that it does in photographs. Anyway, It all worked absolutely fine on testing and produced a decent espresso. The steam boiler I could hear a slight hiss from and upon inspection noticed a little weeping between the top/bottom boiler sections. The plan is to completely strip, clean, re-seal and rebuild the boilers, 3 way solenoids, OPV etc. Clean up the casing and framework. Add all the Arduino gubbins. Features/Mods: 1. I've already modified a V1/V2 Silvia wand by cutting and welding the "ball joint" section from the old wand onto the Silvia wand - So now it articulates! 2. Arduino controlled PID's with PT100 sensors and SSR's. I'll program the steam boiler to go into Idle mode after 5 mins of no activity and reduce temp to save the seals. 3. An SSR to PWM the pump so I can add pre-infusion and possible pressure profiling at a later date. 4. Volumetric flowmeter so I can switch between volumetric shots, time-based, or manual 5. Possibly add pressure sensors for boiler pressures (and brewhead pressure if I can figure out how) 6. Will add other features like On/off for service boiler, descale/backflush programs, steam boiler auto-refill etc 7. Remove the two useless temp gauges and replace them with OLED displays 8. Original switch gear will be replaced, possibly a d-pad/joystick type for scrolling through menus Photos of the machine in it's various stages of disassembly below: https://drive.google.com/open?id=1B3v_CZkXpclEsZ6LjCiI0q16ndA4oxRd Any ideas of features that I've missed or would be a good addition please let me know. Any information of any kind would also be appreciated, always good to ehar other people's experiences of similar projects. Cheers, Kev.
  11. Gaggia Classic Pre Philip - Heavily Modded (PID, OPV, IMS shower screen, Silvia Wand, bottomless PF, IMS double filter) - £200 ono inc postage Machine was stripped and rebuilt and descaled this week I did notice that after the descale the steam wand may not be fully closing but this really is minimal when at steam temp and I assume with passing more water it would close fully again as it worked perfectly before. This comes with a lot of extras to list for this so will do my best but everything you see is included. Motta 58mm Tamper 2 xGaggia portafilters Bottomless portafilter Backflushing blank filter 2 x Original Gaggia double filter baskets 1 X 21g filter Basket (Came with Bottomless unknow make) 1 X IMS 12/18G Filter Basket Original Steam Wand Original Shower Screen Original Double and Single Pressurised filters and creama device Original Spare Pump Original Classic "Spoon" Now has a MrShades enclosure, cables tidied etc
  12. So I am just in the process of gathering all the parts to do a DIY PID controller mod to my Classic I know there is a very helpful chap on here who will supply a whole kit - but since I am an electromechanical engineer by trade I thought i really should have a go I'm using a Rex C100 clone for the controller - so 45x45x100mm footprint I would really like something that fits aesthetically with the brushed stainless finish of the machine and as small and unobtrusive as possible. plan to mount it to on the right hand side of the machine. so was initially looking at extruded enclosures - but very little out there that fits the bill size wise. there is this folded aluminium silver painted option which is about the next best I have come across https://uk.rs-online.com/mobile/p/products/0244134/?grossPrice=Y&cm_mmc=UK-PLA-DS3A-_-google-_-PLA_UK_EN_Enclosures_And_Storage_And_Material_Handling_MOB-_-Enclosures%7CInstrument_Cases-_-PRODUCT_GROUP&matchtype=&pla-394256332783&s_kwcid=AL!7457!3!319513463502!!!g!394256332783!&gclid=Cj0KCQiA-c_iBRChARIsAGCOpB0SJIMu8dNPAMTKa5Wq0f3NLWzPfktg3RFqCops2ddJXTPax2307nYaAu89EALw_wcB&gclsrc=aw.ds or I thought perhaps to use a 50.8mm extruded aluminium box section, as the controller would be a snug fit and make a simple cover for the rear.... what are you guys using ? photos or links would be perfect
  13. Hi, just joined. Been on a coffee journey for a while now Went from a caffetierre to espresso style coffee a few years ago and have been happily using a Delonghi EC330S - which does a decent job ( if it is having one of its good days ) however the delonghi is 12 years old and becoming more temperamental by the day, so it looks like its time to upgrade I was going to go for the bean to cup option, but I'm on a budget and have also become quite attached to teh manual process. So, after a bit of google research, I have just bought a Gaggia Classic in need of a bit of TLC and plan to get that up and running over the next few weeks ideally with a DIY PID setup and maybe a few other tweaks looking forward to lots of tips on what's what from you guys feel free to chip in with thoughts, tips, questions or unabashed barracking!
  14. As some of you may recall from an earlier thread of mine (a few months ago), I got frustrated when fitting the PID (to my Classic) because I couldn't find a suitable, nice looking enclosure. In the end I "made do" with a black plastic one, and then had to take a dremel to it and hack it around. Everything else I could find was too small, too big, too ugly, too - but just wrong. So - I started the quest to help others in my situation... as these PIDs are 1/16DIN (45mmx45mm) and there just seems to be NOTHING that is currently made (even on eBay or AliExpress, or anywhere) that will allow you to take a PID and drop it into a premade enclosure. Now, after a few months (and even obtaining quotes from factories in the UK that wanted about £100 [seriously] to make these in reasonable quantities), I think I'm there. So - here is my custom PID enclosure, in silver anodized aluminium, with 45mmx45mm cutout in the front and a 10mm hole with rubber grommet in the rear. I'm supplying them with the "stupidly super sticky' double-sided tape to stick them to your machine of choice (or anywhere else you want to stick them!). Some pictures from my iPhone.. I'll try and get some better ones soon... And here's the tape: You can buy something v similar from Auber in the US, for about $25 - but then you have to add shipping, duty and VAT - and you're at around £40+ to get your hands on one in the UK - which is bonkers. So - these are £20 delivered to Coffee Forums UK members. They include the rubber grommet and two strips of double-sided tape (but obviously not the PID shown in some of the photos). I'm happy to quote for International delivery if anyone from anywhere wants one, drop me a PM. This enclosure will allow you to mount the PID using the clips if you mount the case vertically (with the PID inserted as shown in the pic). The PID will obviously fit in either horizontally or vertically, though the clip won't fit - so if you want to mount the case horizontally (for some reason) then you can use tape or velcro or some other fixing method to hold the PID inside the case rather than the clip. If you're truly enterprising, and brave, then it MAY be possible to modify or shave a few mill off the clip (or case) to get it to fit - but I can't recommend that! Anyway, the PID slips straight in and the clip holds it beautifully when it's vertical - which is my preferred way to mount it anyway! If you'd like to order one, then drop me a PM and I'll send you payment details. I have an initial order of "a few" in stock ready for quick delivery. Shades
  15. So I'm in the process of installing a pid to my classic, and I just have a question regarding controlling the heaters. Am I correct in my assumption that I'm disconnecting the thermostat and wiring that to the SSR? so that the wires going through the termostat, actually control the heaters? I can't find a concrete schematic for connecting the PID anywhere (Or it's not clear enough for me I guess)
  16. Hello I am selling my Gaggia Classic and some accessories The machine is in good condition Mods include: OPV set to 9 bar, silvia steam wand, and a Mr Shades PID which has really transformed this machine Included in the package is the Gaggia classic machine, standard portafilter (double and single spouts included), bottomless portafilter. Baskets included are single (accepts pods) and double pressurised baskets, 18g VST and a triple basket (only fits the bottomless portafilter due to its depth) and a blank for flushing Asking price is £180 and collection only from Northampton town (J15-J16 on the M1) Sorry for those that live too far but I do not wish to go through the hassle and risk of posting this item, but could meet halfway depending on distance and fuel being covered
  17. Good evening, I'm new here but pretty set on getting the Gaggia Classic and adding a PID. I can't seem to find any comparisons on the systems, and the last best PID kit thread dissapeared into DIY. I'm looking at buying a kit rather than doing a full DIY, I just don't have the time. As far as I can see theres MrShades kit which looks great, the Auber kit which offers the same options as MrShades so not much point looking at that or the mecoffee kit which has the app integration. Anyone know if I'm missing any or which is best? Cheers
  18. Now that I have a @MrShades PID on my Gaggia classic I thought I would look at how the boiler temp changes over time. I'm interested to know if the behaviour I am seeing is 'normal' or if there is something else to optimize. Here is a graph of the PID temp vs time during a 35s shot. I have the initial temp (of the boiler) set at about 106. This is because when I tested the water temp at the brew head (with a styrofoam cup and thermometer) this was the temp reading on the PID that gave me about 93' in the head. This may be too hot (?) but the taste of the coffee seems better at this temp than at a lower temp. I suppose the graph isn't revealing anything too interesting - as the extraction starts colder water is coming into the boiler which is then losing temp until the heating elements kick in. I guess there is a question about: - is the heating starting soon enough or is the temp drop too great? - does this cooler water get to the brew head and is that affecting the taste? Does anyone else have any figures about how the temp changes on their PID so that we can compare to see if we are at least in the same ballpark? I'm trying to think of a way to measure the temp at the brewhead effciently (I have about 99 cups left to experiment with). This is all part of a possibly never ending process of ticking off things that could potentially be sub optimal in my setup so any help is appreciated.
  19. Regrettably up for sale is my 2012 Gaggia Classic with PID fitted by previous owner for great control of the brew water, not set to control steam temp but as you can see the temp rise when switched to steam I've always found it great just to know when to start steaming. You could wire it to control the steam temp if you wanted. - It's got the OPV adjusted to 9 bar. - IMS shower screen and silicone gasket. - It's also got the Rancillio v3 wand upgrade not the normal v2 mod, its a bit thicker and on a ball joint, I've loved that particularly. - Gaggia double spouted pf & bottomless pf & old pf with blank basket - LM 17g basket (and a couple of Gaggia baskets I never used) - I'm in West Yorkshire (Huddersfield) so no problems with scale but its still been descaled probably every month to 8 weeks and backflushed every week or two. For everything above I think £180 collection ono or £200 with insured postage [sold] (no original box but can double box and package well) Collection would be preferable but if fuel costs were covered I could maybe travel say an hour from Huddersfield. I work in Leeds so something could be arranged there aswell. The only reason I'm selling is because since starting work full time after university in a brewery I'm doing pretty long hours and have found myself going for a v60 or chemex at home and my aergrind&aeropress at work so sadly my classic and mignon only get my attention at the weekends and I can't justify keeping them. I've absolutely loved them both but plan to stick to filter brewing for a while and return to espresso later. I will post the Mignon mk2 for sale in a seperate ad. Also for sale seperately or could be bundled above if there was interest is: 1) 58mm tamper with smoked oak handle £10 posted [sold] 2) Hardly used tub of cafiza weighing 934g £7 posted 3) Rancillio v2 wand with Gaggia fitting £7 posted [sold] 4) Unused chocolate dust shaker and templates £3 posted 5) Gaggia bottomless pf made by MartinB (the one with the square handle in the pictures) £15 posted [sold] 6) OE funnel £16 posted [sold] 7) Black grindenstein knockbox £10 posted [sold]
  20. After using my Bean to Cup machine, I want something more advanced, better, essentially a proper espresso machine. I would like a controllable PID for the brew temps, and the Expobar caught my eye (mainly because it seems a very reasonable price). Am I picking a good machine? Should I go more expensive for any reason? Sorry I might be a little vague here, I'll let my thoughts out aloud; - I want a dual boiler (I suppose is directly related to my third point here) - I much prefer the "Rocket Appartamento" style of design rather than the "Profitec 300" style of design, hence picking the Expobar - Although I might not use the controllable PID to start with, I know will want it once I am more experienced, hence picking a machine with it That's as much as my knowledge takes me to. More than happy for people to question me to help guide me, if someone thinks I may have not thought it through correctly/thoroughly enough. This will not be an imminent purchase, much more likely to be towards mid next year at the very earliest. But I like to plan ahead, and hopefully if I start this thread now, I can collate all the necessary information to help me once the time comes. I would love to rush out and buy one yesterday, however it's simply not possible for a few reasons
  21. This post is more mostly about installing a PID on my Gaggia classic,because when I was looking to do it I could not find a specific post, blog, or video that explained it step by step. Thank you for reading—I hope it helps you with your project. Recently I took my Gaggia Classic out of storage and dusted it off. I put it up and nearly forgot about it when it completely stopped working. I pulled it out of the attic last week after I did a little work on my encore baratza grinder. It reminded me that I was never able to pull a good shot of espresso from my Classic due to the OPV (Over Pressure Valve) being set the the factory settings of 14 bars and the mechanical temperature control switch caused the water temperature to vary 20 degrees. The OPV was super simple to adjust: You can build the pressure tester or buy this kit ($28) on Amazon: https://www.amazon.com/gp/product/B012WQ5XLK/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 The temperature took a lot more research and was a lot more difficult to install. I learned a lot about PIDs, which are basically small computers that read the temperature inside the boiler and send a signal to the heating element to turn on. The advantage of the PID over the mechanical is that it is more sensitive to temperature change and also the PID can vary the amount of power sent to the heating element. The mechanical switch is either on or off (100% power or 0% power). The PID initially runs at 100%, but as it gets up to the desired temperature it ramps down. At the desired temperature it might only send 1% to 5% power in 1 second intervals to maintain the right temperature within a few degrees. That's a simple explanation of a PID, but this George explains it better than I ever could: I had very little experience with electricity, so this video and this blog brought me up to speed:https://www.youtube.com/watch?v=jGufeODqU6g https://kabalin.blogspot.com/2014/03/gaggia-classic-controlling-temperature.html I got really lucky that I bought the exact PID that George has a video wiring and programming, but its not super difficult to do either using any PID if you watch these videos and do a little research.Its the Inkbird ITC-106VH in case Amazon stops selling it. It will work in Europe and the USA. https://www.amazon.com/Inkbird-Temperature-Thermostat-Controllers-Fahrenheit/dp/B01KJZMWSI/ref=pd_lpo_vtph_328_tr_img_2?_encoding=UTF8&psc=1&refRID=DY8Z2A07DA6DMWWMA604 The temperature sensor included the Inkbird kit does not fit into the Gaggia Classic, you will need to buy a thermocouple from Auber ($31.99 shipping included): https://www.auberins.com/index.php?main_page=product_info&cPath=6&products_id=21 Programming the PID seems daunting, but after George walks you through the steps, it will be a lot easier: One thing that took a little playing around with is under the sensor screen, you will need to change the character that looks like a “y” or “k” to the character that looks like “Pt.” This is only for Inkbird models—it will be different for other manufacturers. Wiring you will need assorted gauges of wires, the blog above explains the wiring for the Gaggia Classic and has very helpful pictures. You'll need terminal, piggyback terminals, and wire. I did not have any luck finding piggyback terminals at Home Depot, Lowes, Autozone, or O'Reilly's. I bought them off of Amazon: https://www.amazon.com/gp/product/B0195UKJWY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 It was fun learning about PIDs and wiring them. All in all, I am happy that there wasn't a step by step tutorial for adding a PID to my Gaggia. I learned a lot more and I feel way more confident that I could install another PID on any semi-automatic espresso machine. I'll post pictures later.
  22. Hi everyone, A couple of weeks ago I had a mishap with my Mecoffee Pid, which sadly resulted in the melting of what I believe to be the switching transistor (though I might be totally wrong, see pics attached). I've tried contacting Mecoffee, to no avail. My only remaining options are either to go for another PID with a better heatsink on the chips, or try a cheaper solution, which would simply mean replacing the melted chip and crossing my fingers that it would pop back to life.... However, since the chip is kinda FUBAR, I can't read the serial number, and there are hardly any high-res pics of the board online from which I could get the model of the wayward chip. Has this happened to anyone before? Does anyone have any thoughts on this, or could someone perhaps post a high-res pic of the board or chip? Huge thanks, Nitay
  23. Hey guys, I upgraded to a Fracino Piccino so it's time to sell my Gaggia Classic. This machine has served me very faithfully for the past year or so, and now it's time to find a new home for it. Most of you on this forum will be aware that the Gaggia Classic is one of the most popular "entry" level home espresso machines that produces a brilliant cup of coffee when handled properly. This particular Classic is also all modded out so it's even better! The mods: OPV (Overpressure Valve) mod set to 10 bar via Pressure Gauge which means it's actually a dynamic 9 bar, as required to meet the "official" definition of espresso Rancilio Silva wand instead of the crappy default steam wand PID mod - A PID stands for Proportional, Integral, Derivative. What that means is that the PID basically sends multiple commands every second to the heating element to ensure that your temperature is extremely precise. A normal Gaggia Classic without a PID will at any point of time have it's temperature range from 85 - 98 degrees or so. To use your machine effectively, you will have to learn to "temp-surf". Long story short: With a PID, you can expect your boiler temperature to always be within half a degree of your desired temperature. You will not need to temp surf - just let the PID do the work! Along with the machine you also get a portafilter with a double spout, a double basket, and a triple basket. I am looking for £200 for this, before shipping. DISCOUNTED TO £180! You are welcome to test it and see it in action at my place if you can make it to M3 Manchester. I also welcome pickup with cash payment. Unfortunately I cannot deliver as I do not have a car. I am happy to post, if you are willing to pay for postage. In my experience postage is usually £14 - £20 depending on the insurance you want, the speed, etc. Please feel free to ask questions!
  24. Hello everybody. I've been a lurker for a while but finally joined I thought I posted yesterday but it doesn't seem to have appeared. I've got a Gaggia Classic to which I've added the standard Rancio steam wand and I splurged on a Malkoenig grinder. I also got an Aubin PID sent from America which a friend installed for me after doing one of his own. The new thermostat is installed and the display seems accurately to measure the temperature. However, it only seems to measure the temperature, it doesn't seem to influence it - the kit looks installed correctly and I've fiddled with the settings without much difference. The temperature reduces to 102 then heats for about two seconds which then takes it to about 116 and so the cycle continues - as the video below shows. I'd be very grateful for any advice.

  25. Probably a question done to death on here but.... Having had a second hand silvia for a few months I am not particularly convinced by the consistency of the extraction and am thinking about installing a PID. But given the expense I am interested in views on the cheaper solutions. The mecoffee interests me but the product seems hit and miss on quality. Be great to get some feedback from those who have used various solutions. Cheers
