3 Leaves LED Rotating Gyroscope DIY Kit Soldering Project Electronics Kit Soldering Practice Kit for Kids Adult ISolderStore

Fun project, no issues. Good stocking stuffer.

I found this to be a straightforward kit to assemble so long as you understand a few things. SMD- Surface Mounted Devices, these things are manufactured to be tiny. The little parts are easily lost or scattered when a cat jumps up on your work surface, take precautions. You have a few extras but be careful, I have special ceramic tweezers for handling the little things. The primary challenge of this kit is the advanced soldering skills required to manage the minuscule parts that would rather stick to the soldering iron than the mounting pads. Parts placement is straight forward so just stay at it and watch polarity on the LEDs. Once you finish you have a really cool fidget spinner that impresses everybody.

Okay so the parts are TINY and I lost two of the resistors on my carpet within the first five minutes, so definitely do this on a clean white surface. The instructions aren't super clear about which component is which so I had to do some googling to figure it out, but once I got going it was actually really satisfying to work through. When it spun up and the LEDs actually lit I felt like a genius honestly. Worth it if you want to practice SMD soldering and have some tweezers handy.

This is a very decent and challenging kit. It has very clear instructions and board markings are clear enough for someone who doesn't do a lot of this work, such as the negative mark for the LEDs. The parts are the smallest I would want to build an entire kit from. I believe they're 0603. Any smaller and the parts would be beyond annoying to handle. As with all smt parts, the most challenging part is getting the components out of the package. There were 2 spare 101 resistors, one spare of the other value, and some spare LEDs. I wish they gave a spare capacitor since I lost the only one included. I managed to find a different one to get my kit finished though. Over all a great kit, and unlike other practice kits, this one is fun to play around with once it's finished.

The kit was of reasonable difficulty and my 9 year old was able to do the soldering herself with my support. I would still recommend starting with a through-hole kit, which I had done with her earlier. The kit included some extra resistors and LEDs but we did not need them. She was very proud of her work and really enjoyed the patterns created by the spinner.
