Small low profile
I needed a low profile low current switch with multiple on off contacts. This does the job.

Works well

Fun kit but needs instructions!
3 of 3 found this helpful I have a good tech background so it was pretty easy to assemble.
Make sure to solder in all the resistors in the heat sink area before mounting the heat sink! Also mount the transistors ( or fet’s?) with heatsink paste if you have some and make sure the mounting screws are tight.
The cons
It really needs a link to a assembly diagram. Adding the resistor color code in the info would be a big help to many as well. If you have a ohm meter just measure them, it’s faster! The holes for the led’s have a + and - and the silk screen label doesn’t show the flat side that is the - cathode. So insert the led’s with the flat side ( cathode) into the - hole.
I used hot glue to mount the coil and that went well. Mount the coil with the arrow up and remove the arrow sticker and raise that wire to the top. It’s the spark wire and don’t cut it. Just tuck in in the top of the coil to shorten it.
The bottom coil wire insulation will melt when you solder it to the pad.
The red single turn wire has to be wound clock wise from the right solder pad and cc wise from the left solder pad. If you wind the red wire the wrong way the second led will not light and no spark. Just reverse the one turn winding.
It really needs 20-24v dc to work well. I used a boost regulator to convert 12v to 24v. You should have some kind of a 20-24v power supply available.
The pros.
Works (small spark) well and does play music as advertised!
