Spent hundreds of hours getting this right but i'm very proud proud of the results. For the Lithophane part you take your own picture to make it. That's not included in the files obviously. Link bellow for the website to make the lithophane and all the dimensions. I wanted a battery powered ornament to give my mom but can't imagine her changing the battery every few hours of use and all the waste it would do. So i designed this with a high capacity Lithium ion battery and built in micro USB battery charger. battery lasts over 24h in this configuration (driven at 2.9-3v, gives out about 0.2w) Bought most parts on amazon. Once the electronics assembled, it simply drops into the sphere and the top clips in to lock everything in place. Part list: -18350 rechargeable lithium ion battery (amazon or bestbuy or hobby shop) -TP4056 Micro USB Lithium Battery Charger module (look at the pictures closely, 2-3 different styles available. Only one will fit) -1W white LED star with 20mm pcb. I think the 3W LEDs will also work because they are usually driven at higher voltage but here they will get same voltage as the 1W LED. (amazon or aliexpress) -22ohm resistor, 1/4w (any electronic store) -7x7mm latching switch (amazon) -bits of small electrical wires I download the ornament lithophane on Lithophanemaker.com and select the globe option.https://lithophanemaker.com/Lithophane%20Sphere.html Detailed and pictured assembly instruction PDF now included with the files.
