Tiny Cheap Fluid Bed Roaster by Tije and Jan

(also see Daily Coffee News feature ) Tije designed and made the following structure for a tiny and cheap fluid bed roaster, to which Jan van der Weel added the Arduino parts, electronics and programming: Sketch by Tije de Jong Jan sourced a very cheap blower (€ 11) to start with, Tije developed and constructed the mechanics, Jan built together and programmed the TC4 / SSR electronics. On his blog, Jan will specify exactly how the TC4 part is combined and programmed and I will copy these details into this blog entry, just as Jan will use this video in his blog. We did a few test roasts to make sure it works at all and it does. Towards the end, the first roast tended to get a flat BT line and airflow was slightly decreased. 200g seems max load of green beans. Second roast a little more power was given to the heater. Next we will try the Background Roast driven by the PID software of Artisan. A week later, with updated software that works better to change the fan

Time to PID a Pavoni

(Finished project on http://kostverlorenvaart.blogspot.nl/2015/01/finished-pavoni-fuji-pxg4-pid-probe.html ) Several models of espresso machines have a PID on board these days. As far as I know, all of these are used as mere thermostats, making sure the boiler (and sometimes a second boiler) is kept at the right designated temperature, and since temperature and pressure go hand in hand inside a boiler, also the correct pressure. For a brew boiler, the temperature is most important even though the pre-infusion pressure is relevant as well in a lever machine. For a steam boiler, the pressure is most important to be able to steam that milk to a creamy froth. Still, these values, pressure and temperature , cannot be seen separately. A problem for most PID devices is that it's HOT inside an espresso machine, around 50ºC and the PIDs are mostly designed to survive in an environment of 60ºC maximum. The result is that such a PID inside often has a limited lifetime. On the curr

TC4+ boards and Arduino controlled roaster by Matthias Gerstgrasser

illustration by Matthias Gerstgrasser On the mailing list for Artisan users , Matthias Gerstgrasser posted a report about his coffee roaster project, with a link to a beautifully illustrated, complete step by step guide of his work on Instructables: A while ago I posted a few messages on here regarding automation for my hot-air popcorn roaster, and was asked if I could share a writeup of what I had been doing with my setup. I know it’s been a long time, but I haven’t forgotten, just got a little sidetracked (more on that below). I have finally found time to do this over the last few weeks though, and compiled a step-by-step guide of how I modified my popcorn machine. This is now available on Instructables: https://www.instructables.com/id/Arduino-controlled-DIY-Coffee-Roaster/ Do let me know if there’s anything missing or anything that could be improved. I intend to keep updating the guide as I find ways to improve it or as new developments occur. I am also discussing b
