  1. For those with interest in the performance of the Kaffelogic roaster I append a couple of images. One is the profile log and the other, clearly, is of the beans. The profile was Firestarter, developed by Rob Hoos, and the roast level was 2.5. The beans are Yirgacheffe; 120.03 grams in and 100.66 grams out; a 16.1% loss.
  2. If I recall correctly I responded to an email John Robson, sent to early Kaffelogic backers, that asked for suggestions for dealers in coffee equipment around the world. I replied suggesting two in the UK and we fell into a short conversation. I also message the company founder and Kaffelogic inventor from time to time; I still do; I tell you this in a spirit of openness. I have made a number of suggested improvements to the software, the firmware and the the hardware. Some of which have been adopted. I also ask for brewing advice in getting the best from my machine. Is it OK, then, that I recommend the Kaffelogic, in your view? Or have I somehow disqualified myself from comment and recommendation. I think being an early backer of the product has given me an almost motherly sense of responsibility for Kaffelogic and a wish for its success. Did early backers of the Niche Zero Grinder, here, feel the same as it became successful? I roast coffee and brew espresso for my better enjoyment; I have no financial connection with the company; does that assuage your extreme cynicism? I seem to remember a strap-line on this site that stated it was 'said to be one of the friendliest communities on the web'; I don't ever recall having to account for my posts so much on any other fora to which I belong for recommending a product. I initially made this post because a single brand roaster seems to be the go-to device for home roasters and I sensed a collective blindness to the brands failings. I don't know where you roast your coffee but I roast mine in my kitchen under the cooker hood with the extractor fan on. I don't know where you store or keep your roaster when not in use. I keep mine in the kitchen next to the hob. My roaster looks not unlike a ECM grinder in form and is at home in a kitchen environment ready to be used instantly.
  3. I started this thread and my only connection with Kaffelogic is that I am a happy customer. I fail to see any reason to push back against a stellar product that is now winning prizes for its users. I visit NZ for family reasons whenever possible and noticed Kaffelogic on the NZ version of a Kickstarter style website and became a backer. Kaffelogic started in the same way the Niche Zero Grinder started in the UK. Niche has grown to be a well respected product and I am sure the Kaffelogic Nano 7 will too. As to price, remember if it is exported from Oz or NZ then you shouldn't pay their local sales tax; so ask the dealer for an export price. Yes its roast capacity is smaller than the Gene but from my point of view, as a home user, that is a strength; I can have two or three single origins on the go and be fairly secure none will go stale waiting to be brewed. And there is absolutely no hassle putting in a 120g load of green beans and spending 9 minutes roasting another batch ready for next morning. This product challenges the norms set by home drum roasting. No hassle; no burnt batches just the surprise of good roasted coffee. I speak from the experience of having done 185 roasts on my machine delivered in April. Finally, I asked John Robson to update this thread as to answer the comment made by mctrials23 as I knew there were plans to bring the Kaffeelogic Nano 7 to the UK. So, thank you John for doing that and I apologise for the prickly and suspicious reception you've been given. Apparently, we lack the Kiwi friendliness here in the sad old UK.
  4. These days importing is easy for private users. Just know you will be taken for 'import duty' at +20% on the NZ/Au purchase price. Shipping for mine was around £50. NZ and Oz suppliers here https://kaffelogic.com/index.php/home/buy-now As for the Gene - without any process control - it really must be useless. I'm fussing over power inputs of a few percent to get my Yirgacheffe even better. There is no way on this earth a Gene could get close to following a profile the way the Kaffelogic does. I fail to understand the Gene's popularity.
  5. For those that have taken the plunge and imported a Nano 7 from NZ, it is heartening to hear that someone came second in the Coffee Snob's Golden Bean Home Roasters Competition, Espresso Class, using the Ninja profile as supplied with the machine. The competitor was Mark - "bruiserbbq" as you will see in the results sheet below. https://coffeesnobs.com.au/general-news/52990-home-coffee-roaster-competition-2019-a.html#post664702
  6. Kaffelogic Nano 7 is the bees knees. It is a small PID-plus controlled, profile following hot-air roaster. Kaffelogic a small company based in Dunedin, New Zealand, used NZ's PledgeMe for kick-starting and getting funding so as to be able to fully tool up and seek finally electrical approval for their small 120g profile following roaster. I was an early backer and received my machine in April and so far have done 133 roasts. It performs very well. It comes with its own software - Kaffelogic Profile Management Studio - that allows the designing of roast profiles to match bean requirements. There are some profiles from the manufacturer and now NZ users are now starting to upload their own. See Kaffelogic.com/community. All profiles are logged to a USB stick plugged into the machine during roasting. The KPMS software is compatible with Windows, Linux and I think Mac. It has grown in sophistication since April and allows full control over the drying, Maillard and development phases. The machine sits under a cooker hood whilst it does its roast. and is attractive enough to keep on a kitchen counter for daily use. Some coffees are quite pleasant next morning, after a night-before roast, whilst others need time to settle. I understand Kaffelogic are in preliminary discussion with BellaBarista and others to bring the machine to the UK market. Kaffelogic intend to be at London Coffee Fest next year. Machines are on sale in NZ now and can be imported; The NZ price is 1200 NZ$ ~ roughly £610 but you'll pay import duty on £580 of that at 20%. If you think this is an Ikawa in another guise - don't. This is a serious roasting machine and is already being used by NZ professional roasters to develop profiles for their coffee. (My only connection with the company is that I was a backer and received a roaster at cost price for my trouble. But as you may gather, I love it!) The first appended image shows a pre-production machine finished in stainless steel. Current production machines are black. The second image is a profile log of an actual roast - an experiment with some Ethiopian Yirgacheffe beans. The blue line is the profile; the red line is the actual temperature profile delivered by the roaster; the green line is the rate-of-rise and the brown line is the differential of the rate of rise.

    Thank you both for the suggestions - there are a couple to follow up there. With views but no replies here for over a week I was starting to wonder if it was something I'd said Or had I missed showering on the day of my post? Currently I am using Redber after a less than stellar experience attempting to buy from CoffeeCompass. But I will try the other two mentioned. The manufacturer's forum for my roaster suggests visiting a local coffee roaster to buy beans and talk profiles. CoffeeCompass (CC) is within striking distance of me but they seem to repel borders with a 'no visits without appointment' message on their website. Well, OK; on the one hand, one man up to his armpits in roasted beans is always going to be busy; on the other hand a part-time small business may be conducted in the evenings - with internet businesses who knows the truth?. I tried to order from them but the order failed at the PayPal payment - transfer back to seller stage - on two attempts. I had no response to initial an email to CC and a second, a week or so later. It took three attempts and a screen-shot of the error to elicit a tired, unhelpful response with a hint of sarcasm after I mentioned I'd ordered from Redber. If your mileage is different I may just have caught them on bad-days; perhaps business isn't going too well...

    ...roasting is my current interest. I have a Kaffelogic Nano 7 that PID follows profiles to roast with attempted precision. I would be interested in suggested sources for greens. Also it appears the recommended roast profiles to best match beans doesn't seem to be widely spread; if anyone could point me in the right direction I would be grateful. Or is this the stuff of trade secrets? I roast for espresso and have a Synchronika and a Niche.
  9. Woodwork devolves down to the accurate removal of waste. All the tools for metalwork, that you already have, will work on wood; maybe less efficiently. Joints are used both for location of mating surfaces and to increase the area for glue to act on. That about sums woodworking up. Consider your needs to joint sheet material at 90 degrees and/or edgeways and how you will go about it; possible solutions your anwer here will determine what you buy. I would avoid rushing out and buying any power tool. You can do most of what you need with basic hand tools most of which you appear to have. A coping saw for cutting curves; a tenon saw for cutting to shoulders; a few chisels for removing waste - 6, 12 and 25mm are a start. Buy others as you need. Only buy a power tool when you really have a need. But please buy a wooden mallet for striking chisels! Hammers are not suitable although the World and his brother seem to think they are these days. A router 'could' be an almost complete solution with jigs etc, but there is little point for one-offs. A sturdy bench is an absolute priority; you can't get your shoulder behind a chisel on a rickety thing in the garden. Also bench hold fasts and a good vice are paramount.
