Two more yet again. Assembled and camera working. No function disabled, except for auto cleaning. Manual cleaning only.
Need a less bulkier remote jack. Space is adequate but tight. USB is available for remote or tethered shooting.
Next, attach TMP36 temp sensor. No calibration necessary. Range -40C to +55C. Voltage change across diode with temp change. Analog from temp sensor switches a logic level MOSFET to control current to Peltier device. No PWM to Peltier or heat sink fan. Temp control +/- 0.1C, but it remains to be seen whether this is possible in practice. I will post a a readout when it's up and running.
