Ultimate DIY Roaster

[saoye]

I saw your machine in another post....

But nice sexy machine...

Bit flashy with those LEDs but one question...

Perforated drum or not?

Heat source?

I believe OP mentioned the entire roaster was built around a supermarket colander so that would be perforated. Heat retention in a colander would be minimal in comparison with commercial drum roasters that have very thick gauges so the roast would rely very heavily on the heat source. Still the result shows very even roast. Looks great!

Nice work on the roaster man!

Quick question, did you figure out a way to control the dc fan speed with the tc4c with roast logger?

So impressive. Good to see people that have a passion; spend their time and ingenuity on achieving thier goals. That is an impressive looking coffee roaster.

Hi Scott,

Thanks, I haven't connected the fan yet. But the TC4C and Roast Logger are already equipped to control the fan, it would be just a matter of hooking up the fan and increasing the voltage after the TC4C as it only puts out 5v. The tricky bit for me would be using the heater control, as it is designed to control an electric heater not gas.

My plan is to install a solenoid valve for the gas, which should work as Roast Logger controls the heat by turning it On or Off. This should translate to Open or Closed. I've found the valve I would need, now I've just got to find the time to install it.

Cheers
Marty

Very impressed, do you have any pictures of the inside of the roasting chamber and the heat source?

I'd also like to know how you ratio the size of the chamber vs. the amount of beans.

Reasoning is simple, i'm already looking at doing something simular, maybe not as grandios... I have access to some Stainless tubing and know a man who can turn them into drums etc.

Some really nice features... the glass window especially, and love the idea of the arduino - I have about 2 dozen of them sitting around doing nothing

When I read the thread title i was expecting photos of some hybrid bread machine-heat gun macgyvered into one solid unit.....this blew my mind!
