The little battery kept a charge almost all night long. I had turned off the “Brian’s Idiot Monitor” (like that name?) and just let the battery hooked to the charger board. The external battery charger i disconnected and plugged into the wall to reload.
Today i noticed that when i was outside in sunshiny weather, if i had the bag in yhe sun and the ttf still off, it didnt detect it. Just shading it a bit brought the BIM beep back on – so i plan to monitor the values frim the sensor to see if i can tune it better. We shall see!
Tommorow I’m teaching a chip carving class, so i may not get to play with this again until later. I can try to build a wood container to hold this device, if my student(s) make good progress. I can carve the case to personalize it while on my duke checkpoint early next week.
Although, I’m programming arduino from raspberry pi so i can take the little set with me to duke university’s check point… Hmmmm
