With the Velleman MK142 SMT LED Chrismas Tree you learn how to use surface mount components by building this subminiature Chrismas Tree with alternating flashing LEDs.
Build this subminiature Christmas tree and watch it alternately flash green surface mount LEDs! Small enough to wear as a badge or pendant, or to hang on the tree. SMT components are used throughout the kit to give you a great start to surface mount. We know they are smaller than small, so as always, we include extra parts in case you lose or damage any.
