stapled - a 1 minute led diy

because i had too little light when fiddling with hardware in my computer, i just built an easy led lamp.
you need:
1 minute, super bright led, 3v 2025 battery, a brass staple fastener

ingredients	back	side

front	light	finished

leave a gap of about 1mm between the cathode of the led and the battery. this way you can press the cathode against the battery for switching the light on. release pressure and the light goes off again.
