*tap tap tap* Is this thing on?

Anything new in the Milowidget world? My Sonofresco is lonely…  ;)


I'm spooling back up again soon.  My software guru got a job and seems to be working too much and I've been spending all my free time on a kitchen remodel. ;D  but the good news is I'm almost done with my kitchen, so back at the milowidget soon.

I'd sure like to begin my variant of this project shortly.

Control of gas valves is really, really important. I need to start looking at hardware!

You might check out the knife makers forums. Lots of info there on making PID'ed heat treat furnaces would tend to translate pretty well.

Expensive, but there is a solution.  Maxtrol M420RH and a Honeywell Valve SV9501, you need them both if you don't have on on/off valve.  The Maxtrol controls the pressure, the Honeywell on/off, pilot, etc.

I picked up a HVAC damper controller and a PID that will talk to it a few years back... never tried to turn on and off a valve yet...

A damper control "actuator" will control a gas valve, pids are set up to run them.  Much better control if your actuator has slidwire feedback, should see a pot on the actuator or come up with a way to add one. This lets the controler know how open the valve is.  You would need a gas valve that is full on and full off in 90 to 360 degs. The actuators I use at work either swing 90 degs or 180 degs, you can move the stops and get a smaller swing.  I have not been able to find a valve that will do this.  On my roaster I installed a 3/8 needle valve but the adjustment full on to full off is only maybe 10 degs, I need more swing.

Wait... you invented time warp communications? Tell the PID to tell the HVAC damper controller to purchase some AAPL stock!

Any progress?  Getting tired of the Hottop 8828D's lack of features.  :)

I haven't worked to much on it over the summer, but plan to dig back into it in November/December.

I feel your pain on the older hottop.

Just read this thread from beginning to end.  As a long time C programmer, and an owner of a HotTop KN-8828D I'm kind of curious about how it's going.

Thanks in advance.
