Flyandance Juno Time Machine 4.4 Instructions are at https://bit.ly/3prTnJ5 Genius!!! Love it 💙 Artsy. Unique. A family Heirloom. It's smaller than I expected. About 10cm or 4 in diameter. But that's OK. Extreamly High Quality. Super tiny LED's. Has extra parts (that's good)👍 Has 4 stand off holes. Wish the USB plug didn't come out at 3 o'clock(will try to change that somehow) Thank You, flyandance in San Francisco. Wish you could do a step by step online instructions. That would be nice. Order a fine tip, temperature controlled soldering iron. Magnifying Lens Headset. Bright Light. Thin solder. Solder Wick. Flux. WOW, I hope it works when I get finished. I plan to mount it in an old nouveau style Clock. A Classy new. If it works, I'll order more.

Response from Flyandance

Thank you for your kind review. I will absolutely throw in something very nice just for you if you were to order from me again. That instruction is outdated, but it may still help you. I also have a full page of extra info in my site and with full source code available for you to modify the clock if you wish to.
