I’ve been getting great use out of my modded Evil Mad Scientist Laboratories Bulbdial clock (you might remember, I modded it with a touch sensitive strip to turn the display on and off), but it’s been having some problems lately. Because I couldn’t solder to the aluminum tape I previously used, the contacts taped in place were getting loose, causing the clock to flicker on and off. The loose contacts also made functionality very sporadic. The solution was to swap the aluminum strips out with the copper foil I bought a while back from Sparkfun for a whopping $3.
