ok,solar skeleton sculpture in epoxy resin.
I have work on this project couple of days and the project was finished,working great with all 3 function,low voltage led blinker,led torch 2.5mah and oled thermometer with arduino pro mini board.
There will be second video with more details and circuit diagrams but for now I have used:2pcs super capacitors 5.5v 2F in serrial connection so I get 5.5v and 4F (5mah total) 2pcs solar cells each give 2.3v max.one 1n4148 diode and 1000mf capacitor for charging section,white led diode 5mm thrue 120ohms resistor so can pull 2.5mah max current,low voltage led flasher(circuit in next video) and oled 128×32 screen with atmega328p+ds18b20 temp sensor for thermometer.
