roaster control widget

I remember the 9800 was a pain to solder, I almost lost it because I was holding it down too hard, and it "flicked" away.

Looks great. Is the software controlling ejection solenoid, and fan? And if so how are u connecting that to the tc4? I am consumed with anticipation

Yes, it will control the entire Hottop.  I'm planning on using the Jeelabs connection for the display (with an adapter) and then use the LCD plug for the hottop controls (it's conveniently 8 pins of digital I/O, power and ground on the correct pins... except for 2 pins, those I'll re-route).

Time to stop dragging my feet and start ordering parts.  I'm not particularly gifted at soldering, maybe two tc4 boards .

Uh Oh Larry
Does this mean I can throw the board away that I soldered up last fall?  And I've been waiting so patiently, too...

Maybe.... don't toss it yet.  Let me make sure it works before anyone spends any $$

But my tax return is burning a hole in my pocket!! Gotta get some coffee toys soon

Very cool ... this makes the HotTop look like a shoo-in for my next roaster.

TC4 and arduino enroute to my roasting lair.  This is going to be fun

I have it, assembled, and reading temperatures from the hottop, using the "bourbon" program .  I don't know if the newest revision of the tc4 shield is supported by artisan or not.  I cannot seem to get the two to comunicate.  This has been a great learning experence so far.  I cant wait to keep going.

A user came up with a change to Bourbon to make it work with Artisan, and I dont thing the change was made to the "released" version of Bourbon.
It looks pretty easy to make the change, if you know software.

Thanks a million Randy. I'm just jumpin into all this. My next hurdle is getting the tc4 to control the heaters.

If anyone wants to do anything with wireless remote keypads/display for this stuff, let me know. I'll be pleased to share some code (Arduino) that might save you some time. The piece of value is the reliable wireless transmission of array data, of any data type. Adapting what I've done would be fairly simple. Range: about a hundred yards, ymmv.

I was just starting to look into wireless, will send you a pm.

Are you using the Hottop high voltage board or are you using SSRs to control heat, etc.?

[jimec3]

Hadn't decided yet. I am interested in following your end result since it seems it will be tailored to the hottop. Did you go ssr or high voltage board?
