Thanks! No I have none left. The last one is the one I use.

thanks!

Yes, I have one completed PCB and some unsoldered PCBs for the 220 V roaster left. Initially I built it as backup but so far there have been no issues regarding hardware failure. If you are interested, please send me a PM.

It depends what you mean by stable. It is working for me and my usage namely roasting 1 kg coffee in succession either by just starting the roast in the app or by replicating an artisan profile. It can disconnect or you run into a bug from time to time though. When the hardware is done you normally only need to tinker with software, so thats way more comfortable IMHO ;)

@@nvprojects7601 fantastic I will purchsse the parts and will try to replicate your great work… Greetings

only the github linked in the description and google

It depends on the grinder and what is sealed for you. Some ginders are just sealed around the burrs using a piece of rubber to keep most grinds out. Some grinders are precision machined, but I think they are never air tight. Plugging the spout would probably help keeping the CO2 in and thus conserving the beans better/longer but I wouldn't worry too much about that. If you have freshly roasted beans from home or your local roster, they normally stay fresh for one to three weeks in the hopper and start degrading when the volume in the hopper goes down. I did single dosing with home roasted beans fresh, after a degassing period and also kept them in the hopper and in the end I could tell the difference when comparing A/B at most but not from a single cup. The beans do not taste that much different from storing them in the grinder than storing them elsewhere. Keep in mind that a box will also have the air sitting on the beans, especially at the end when the jar empties. Having a jar with a lid that pushes onto the coffee always airates the coffee when opening again, single dosing into small flasks has a higher air (between and over the beans) to overall beans/degas ratio, freezing I would not recommend. So my tip would be to just drink enough coffee to have always fresh beans and buy from a local roaster and maybe purch a few seconds in the morning to get the really old stuff from over night out of the grinder.

yes, only the bean air temp

freezing can also degrade the beans. I do not notice great differences when filling the hopper or just single dosing. The key is for the hopper to be filled with more beans than just a few grams. They keep quite fresh for a week, maybe because the beans still degas CO2. A roaster would also put them in an open container for weeks before the beans are packaged and shipped so straight from the roaster at home you should be good for a few weeks and even store bought coffee holds up better then you might think.

Yes, but you need to build the Xamatin project first. I would recommend to use the artisan version which is also compatible with the hardware mod.

The setting is not absolute. It is close to touching burrs, then maybe a half turn open. It's the original atom and I still like it a lot. Dead space seems reasonable and the coffee is very fluffy, no clumps and I find the less you distribute manually after grinding the better the shot.

Hi, it was a special offer from Londinium. They had some glass hoppers custom made for a different grinder. Since the size almost matches the Eureka I stuck it in with a bit of cotton cloth as buffer. I think it was produced by Torr, maybe check them out.

@@nvprojects7601 great, thanks for the info. Eureka also manufactures and sells glass hoppers. Fits all Eureka models. The link is among the options. :) www.eureka.co.it/en/catalogo/prodotti/macinacaff%c3%a8+on+demand/1/43.aspx

There are many similar LCDs on the market. Just connect it like the manual of your LCD says and change the pin configuration accordingly.

@@nvprojects7601 I have the same lcd can in the manual ST7920 I want to know which pin are bound to work.

Or if you can help me with Gene_automation.ino for Arduino Ide I can change pins. Thanks

@@zichoreduard2729 The code is now available on Github: github.com/nekowokaburu/GeneRev3

@@nvprojects7601 Thanks!!!

No, I never single dose. It is a pain :)

@@nvprojects7601 yeah especially not with that grinder! Unfortunately

@@DylansHomeEspressoBar It is nice to have all ready to go in the morning or when working from home. No measuring can be nice, too. For single dosing e.g. with new roast profiles or for fun my fallback is a Portaspresso hand grinder. For the price of a good single dose electric grinder you can easily get an Eureka plus a good hand grinder which is also portable.

@@nvprojects7601 I may add this to my CZcams channel!

Also checkout the latest version with App and Artisan support :) czcams.com/video/1ynHtYo9W6A/video.html

I would not recommend it, no. Most people seem to like the Niche Zero grinder for single dosing or a good quality hand grinder if you don't mind the "work". I can see if I can make a short video single dosing it in the next days tough :)

Here another retention test. This time the machine was not cleaned before: czcams.com/video/Z7JHpWzfgPo/video.html

@@nvprojects7601 to be honest i dont like the Niche (kill me) hahaha. Right now im considering purchase the specialita. If im gonna buy a better espresso grinder (currently im using the built in Breville grinder), I´d prefer flat burrs :D Thats why I want the Mignon Specialita :D

@@nvprojects7601 Thank you, that was a helpfull video. Now im awared that, despite the bueatiful eye looking of yhe ATOM, i wouldnt be very suitable for single dosing. If we talk about design, I LOVE the Atom more than the Specialita but I have to choose a grinder based on my needs :)

@@sebastiansaucedo9965 The Specialita is not a single dose grinder. I sold mine for the same reason as this video: very high retention.

What's the problem? Did you follow the steps attached in the forum coffeesnobs.com.au/forum/coffeesnobs-discussions/home-roasting-tips-tricks-ideas/48057-gene-automation-mod-lcd-version#post826235 ?

Better late then never. You can get english details here: coffeesnobs.com.au/forum/coffeesnobs-discussions/home-roasting-tips-tricks-ideas/48057-gene-automation-mod-lcd-version#post826235 Also I am working on a embedded wifi version which comes with its own crude Android/iOS/Windows app and supports Artisan :)

The white dial shows the boiler pressure, not the preinfusion pressure.

No problem. It is indeed a very good machine. Please note that this mod with the app is my private work and not officially supported by londinium. They are developing something similar which is available by now with an app to follow by 2019. Also check out my newer version of the app which can show the preinfusion and extraction time and has a new setting to turn the pump on only once which can help yield an extraction 24 % higher than original.
