I ordered the child's shoes from china. Such cool, where the sole shines as it goes.
Future, they're great.
After an hour, one fell. My guess is that the Chinese electronics refused to obey (I replaced the batteries, still nothing).
It is powered by 3 small watch batteries. There is a switch on it and that's it. Later, just routed cables to the sole.
I would like to make this simple layout from scratch, but I do not know how to do it. The whole must be quite small, small switch, 3 batteries, and for this wants to use attiny13. I do not know the programming completely, so the question ... how to do it? I have a USBasp so there should be no problems. Originally it works so that the button is clicked, shoes shine about 5 seconds. The system turns off.
A child in need, please bear with me.
@Edit
I will add in the first post movie and photo layout as it looks:
