I probably won’t be replacing my giant G-shock watch just yet, but this binary POV watch is pretty sweet. Sure, the POV clock is old hat by now, but it’s also a nice example of adding a Li-ionbattery to an embedded project. It uses a MAX1555 li-ion charger and throws caution to the wind and doesn’t bother with any external … Read the rest

Cheap DIY acoustic guitar pickup
February 22, 2008 By 10 Comments
I stumbled on this simple, but effective and cheap diy guitar pickup in my rounds for interesting hacks. Piezo elements haven’t failed to amaze me. They’re usable for electronic drum kit, underwater microphones, running shoes and musical greeting cards.

The RAM’s stored data doesn’t immediately disappear when powered off, but fades over time. To recover the keys, they powered off the computer and … Read the rest
Tin hat bonus: Jetlag got me.
