Hi! The battery you chose is not available. What is the C rating of the battery you chose? (Or what maximum current draw should we count on?)
Weights should be 1000-2000-3000-4000-5000. If you used 0 as a weigh, that sensor value would be lost, or zeroed out here: Value*weight
GREAT PROJECT, thank you very much for sharing!!! One note so far:"The way the algorithm works is by asigning a numerical "weight" to each sensor, which are 0, 1000, 2000, 3000, 4000. ... Line_position = (Value*weight + Value*weight + ... ) / (Value+Value+Value+ ... );I guess a sensor reading is lost, if you weight it with ZERO! I guess weights should be 1000, 2000, 3000, 4000 and 5000, or am I missing something?

Hi, I think you should check that code you posted!
yep, thats what I think, too... Aaaaand, yes, the original 12V version used a zener... This circuit is useless.. :(

Turn An Old Cell Phone Into A Smartwatch
It is one of the best ideas on this site I have come across so far... I made it, but it does not seem to protect against anything. Charging current is not limited anywhere below 2A, and cell discharged below 2.6V. I salvaged from an old Samsung battery. I wonder what the circuit does, if not limiting charging current, and cutting off below a save voltage (2.75V lowest?)... Any idea?
