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.
UPDATE: People keep asking about the breadboard setup. Fair enough. I’ll throw together a quick overview when I get home today.

The Bulbdial clock from Evil Mad Scientist is probably the coolest clock idea I’ve ever seen. Even cooler are my parents, who got the kit for my birthday. The basic idea is that three rings of LEDs cast shadows onto a clock face to form H/M/S hands, somewhat like a sundial, with the hands slowly animating around. A lot of thought clearly went into making this kit, and it’s very nicely done, but there’s a major drawback: I want to use it on my bed side table, where I usually keep a clock, but it’s too bright for me to fall asleep! Of course, that’s been thought of too: in the normal view mode, the three buttons at the bottom of the clock are brightness up, down, and “mute,” which turns off the LEDs entirely. But they’re hard to get to buried underneath the frame of the clock, and it makes muting the display cumbersome in the dark. Let’s fix that!
