Thanks I built mine with the Bake-A-Round, a martini glass, 1550W element and 250W vacuum motor (it's all controlled via a TC4+ board and Artisan). I had a difficult time balancing the fluid bed movement with heating temps...more airflow moves the beans better but drops the inlet heat. I downsized the glass tube to something 1/2 an inch smaller in diameter and that helped some but I still think heating element is underpowered for the roast chamber and fan motor combination You can definitely make it work like that though...Before I added the TC4+ board and began roasting via software, I got some nice roasts by manually "pulsing" the fan off/on every few seconds so it would keep rotating the beans while also increasing the heat but then your ability to repeat a good roast is impossible.

I haven't shared anything yet for pictures or videos but here's something I had earlier. It's design was inspired quite a bit by CK's transparent roaster (https://homeroasters.org/forum/viewthread.php?thread_id=5742) and the Roastino (www.cyberelectronics.org/?p=699). I really just threw it together with parts laying around the house and everything was press-fit together with silicone tape so it's safe for high temps and easily disassembled dirt devil vacuum motor heat gun martini shaker Glass tube sink/garbage disposal mount ...later I added two of the "tornado dust separators" like in CK's build and the copper tubing to recirculate the hot air and separate chaff but ended up abandoning that idea. I think this is still a viable build but you may have better luck with some Tri-Clover parts and a smaller roast chamber...the Bake-A-Round is big enough to handle 1-2lbs batches from what I could tell but a 120V element isn't going to heat it well. jordo_99 attached the following images: Edited by jordo_99 on 02/16/2022 10:50 AM
