Gas assist installation guide
I added gas ignition to my second hand performer out here in Kenya. I purchased the parts from a UK based parts supplier. I followed the installation guide provided by Lawrence at...
From my experience with panels in Kenya, you'd probably want a charge controller and battery. I'd hate to wreck a cook due to the sun going behind clouds. Also 15W at 12V is only 1.25A. Not enough for the HeaterMeter, Pi, Fan and damper Servo I think. I'll let more knowledgeable heads weigh...
The probes all read accurately in boiling water and ice/water so calibration is ok. Nairobi is in the 90s (30°C) and clear blue skies again today. Traffic is horrendous - 4th worst city form Commuter Pain according to the IBM Index. Very quiet out on the golf course though!
I'm in Nairobi for another wee but will try a transformer type psu and also a 12v sla battery to see if this helps. Makes sense that a cheap switching supply could give grief. Thanks for the advice Bryan and Ralph.
John, does the fluctuation increase over time? I have this problem with my on board TC. Starts with a degree or so then increaseincreases over the hours to as much as 4 degrees. I know your TC amp is on the satellite board just wondering if there is a cool root cause?
The VoCore looks really good. The number of small scale Linux platforms keeps expanding all the time. Continuity of supply etc. will make design direction choices really tough for Brian!
Ralph, I removed R18 but still have the problem. Here in the TC in my oven set for 300F. The temp bounces around, up and down by 4-5 degrees.
Changing Power supply and WiFi dongle has no effect. I'm going to try and source an isolated TC. Any other ideas?
Thanks.
A quick test before bed. Three TC's off Amazon/eBay; All three read within a degree of 211 for boiling water but none will read below 60F when in a glass of ice & water. Is there a lower limit on the HM?
