I picked this up on AliExpress a while ago with a pile of other kits, and I have been putting it off ever since. I am really happy that this one is actually both simple and fun to assemble!
We solder up the board, fit a big old capacitor and put the box together, ready for some rail gun action. I do wonder what modifications can be made in the future: more power, bigger capacitors and transistors. Perhaps getting it all the way to 100%?!
