Junk
This kit sucks. No legible instructions and parts are hard to identify. Waste of time and solder.

No es lo que se ofrece.
Es un proyecto para practicar soldadura estaño y llegó armado. También está incompleto porque solo vino la placa. No hay más cables, ni porta pilas.

mine doesn’t work, checked all polarities etc. don’t buy it
what I didn’t like is the fact that it does nothing double checked everything

neat thru-hole soldering practice board that rewards you if you do it correctly
All parts needed for assembly were accounted for with spare LEDSs included. Good amount of components here to give your soldering skills a good work-out. The nice part is that this actually functions if you assemble it correctly which is instant validation if you got things right. The only change I would make is to make the adjustable potentiometer have a higher value (currently 10K ohm) to provide a longer span of the LED cycle. Overall a fun little exercise board.
