I made a very cheap and rudimentary dolls house light using an led, resistor, a switch and a cr2032 battery.
I soldered all the bits I could but for the battery connection I just duck-taped some exposed wire to the battery (!!)
This worked, for a while but the duck-tape is a 'sub optimal' solution - in that it doesn't work
This whole project is meant to be _really_ cheap - so, gathered experts, is there a better (but still cheap) way to connect up the CR2032?
