Well here I am still making those lights.....
but assembling them a little differently....
After taking off all the parts.....
this is the top of the things, after unbending the battery
contact tabs, I pull them up and set them aside still
connected to the triangular PC board.
peeling off the disk on the sticky tape.....
this is the part that makes it really simple to
assemble.
then laying them around in a circle and connecting the
tabs by crimping the ends together......
then some hot glue to hold the PC boards on...
a 100 ohm resistor between 2 and 3
connected the beginning and end wires to 12 volt Ni-Cad
thats it.....total cost $3 not including battery or hot glue.
