Already built the data logger using Stalker V2.
Using one lipo batt 18650 2200mAh and 3 solar cell (each 2volt 50mA max)
It run well about 2 days, but today i got the stalker stop working.
The led keep on, and the logger stop writing to the card.
When checking the log data, i got 25/45/165 on the date.
I don’t see where the problem is.
The temp seem correct, so the lipo voltage
The stalker, lipo batt, and the solar cell sit inside tight container using some of tupperware stuff (it’s fun using them, and cheaper)
Maybe the heat that generate this problem ?
I thought the stalker will survive about 80 degree C.
Maybe the voltage regulator keep the voltage up-high in the high temp ?
Maybe i will toast them in the oven (like i did with duemilanove, and it fail) to test the high temp.
need more infos…
thanks for reading
