Soldering project
Bought at Aliexpress: Heart shape LED breathing lamp kit DIY
Soldered by basicsoldering.com
For Valentine’s day I found this Heart to solder.
You’ll need only basic skills to assemble it.
Extra: The kit came without battery holder. It runs between 4,5v and 6v. I used a battery holder which holds 2 cr2032 3v batteries, 6v together. I had a microswitch laying around.
I found the heart shaped box some time ago in a cheap store.
