Supercapacitor powered arduino LED wrist watch

Hi, this is my stupid project :slight_smile:

Super capacitors are new power source, compared to batteries need different charging and power usage. This watch using 6 capacitors because they have better dimensions. Board have high effective step up converter with operation to 0.3V, because caps are are charged to 2.5V and then are discharged to zero. About super cap power... 5F is about 10 minutes in highest brightness, 20 minutes in lowest brightness. In standby few days. It is hard to test you must wait days :slight_smile:

Some pictures ....
