Short links for February 13th, 2008

Some interesting things I bookmarked on del.icio.us on February 13th, 2008:

• Thing-a-day, Day 11: “Physical” drum loop machine – Arduino based beat recorder/actuator.

Cibomahto’s complete system

• SPKR MiK: How to make a microphone from a speaker – How to make an inexpensive microphone capable of picking up low frequencies that doubles as a speaker and direct box.
• 386ukeAmp – Steve Lodefink built an amp in a coconut. Now that’s just nuts!
