My first roaster ever - a very cheap fluid bed

Many thanks to this community and people who share their builds.
I was about to build a roaster after I found some videos on YouTube - sifters, airguns, bread machines... and at one point I found roastuino project with RC made of french press.
So I was looking for a proper french press to buy and replicate this project, but I started to look for other glassware and found that Carafe from IKEA is better because of its reduced bottleneck.
This is how I found this forum and amazing build by CK, Linnaeus along with many others.

My attempt is not that solid though. I just wanted to build a kind of proof of concept.
And it works.
Now I need to learn how to roast in a proper way. Maybe later I’ll switch to Arduino and Artisan software.
Currently maximum capacity is 300 grams. I use 3.4 kW heating element and 1 kW air blower.

BOM is available at
Total cost is under $100

Nice work on the roaster!

I corrected one of your photos and turned it 90deg.

KKTO Roaster.
That is a neat roaster! Thank you for adding the parts list too -- some one may find it very useful. And it also helps me learn some. Unfortunately I don't think exact parts list would work in USA, due to voltage difference (120 - 220).. I wonder if there are easy swaps for U.S. voltage.
