It's amazing what a little disk can do ... when it's layered with piezoelectric crystals. Piezo disks are impressively sensitive to vibration and can easily be adapted to work as a contact microphones. The trick is the preamp - a basic circuit used to match the piezo's signal to levels compatible with modern audio gear inputs. The resulting piezo/preamp combo can be used for electrifying an acoustic guitar or simply exploring the lesser-heard world of small sound around us.

Matt demonstrates how he uses an Arduino to make a celebrity-silencing remote control for your TV. By decoding the closed captioning track in the video signal, the Arduino is able to look for keywords such as "PALIN" or "KARDASHIAN" and mute your TV, protecting your poor ears from having to hear about them ever again.

How do you make a walking biped robot, with only 3 servos? In this episode of The Latest in Hobby Robotics, Frits Lyneborg from letsmakerobots.com shows you his inventive way of doing just that. The programs used the robot on the video can be downloaded here: letsmakerobots.com/​node/​29379 Tools needed are just very basics, like saw, drill, ruler etc. Materials are the 3 servos, some wood (4 paint sticks), hot glue, a couple of screws and some thread locking fluid. The servos are controlled by an AXE230, and batteries are used as balancing weight. You can use either 3 "normal" batteries, or 4 rechargeable, you just need somewhere between 4.5 and 5.5 volts. You can adjust the the height of the batteries, and there are several parameters to adjust in the programming code as well, to make your robot walk well. You can also port the simple code to any other micro controller of your choise, and add sensors, arms and more to your own robot. If you have never build a robot before, the best place to start is probably here: letsmakerobots.com/​start

MAKE pal John Maushammer (who reverse engineered the firmware in all three Pure Digital disposable cameras and figured out how to connect them to home computers) sent in this amazing pong watch! He writes - "I loved the idea behind the Pong Clock and I've wanted to make my own watch for a while now... combine those two things, and I've got a start at the Pong Watch. This is just an electrical prototype - the hard part will be making the watch case and then squeezing all the electronics in there. The display is a small (1.2") 96x64 yellow-and-white OLED display. OLEDs are neat because only consume power proportional to the number of pixels that are turned on -- for a game like pong, that's a relatively small 1-2% of the display, so the power requirements are pretty small. Plus, the high contrast looks great with a game like this. I haven't worked out the power budget in detail yet, but hopefully I can get a day's use out of the watch, and then recharge the battery each night. The charger would also automatically set the time, so there will be no need for buttons on the watch."
