Christmas tree blinky thing

2 posts in this topic

Last year my daughter (she was almost 7 back then) got interesting in soldering.

So I let het solder stuff together, no function whatsoever. It did not last long, until she wanted to solder something that "does something". 


So I took the challenge and designed this christmas tree.


- FR2 board, copper artwork by me, other side by my daughter. (cheap FR2 is better for using felt tip pens.. almost like paper)

- G2553, all 16pins to simple LEDs, various colours

- simple discrete regulator (another led+ transistor) for more or less 3V

- powered by USB

- mostly through-hole (soldered by a 7 year old), some SMD (where I helped)

- programmed in Energia



merry christmas!
