Need a battery holder in a pinch? Make your own with a few bits from your junk drawer.
Step 1: Gather Materials
Adhesive glue squares
Small scrap of copper sheeting
Strip wires at both ends about 1/4 " Poke two small holes in the end of the match box and insert the wires, bending to hold
Cut the copper sheet in the following sizes
2 @ 3/8" x 3/8" 1 @ 1 1/4" x 3/8"Cut the glue squares so that it just covers the bottom of the copper bit on both 3/8 " pieces and place over the wires to the bottom of the matchbox (make sure that you don't interfere with the copper and wires making contact) Place the larger copper sheet on the opposite end with a glue square
Done! Now wire it to your 3 volt projects as needed!
