Maker Shed

Make: Electronics relay oscillator

I put together the breadboarded relay oscillator experiment from the excellent Make: Electronics book, using the parts from the Make: Electronics Components Pack 1, both of which are available from the Maker Shed. Since the power adapter in the kit has some barrel plugs I didn’t want to sever, I came up with a way to adapt it for use with the terminal screws on the supplied breadboard.

In the Maker Shed: Voice Shield kit

The Voice Shield is an analog audio shield for the Arduino. It allows you to easily add audio to your next project. The Voice Shield uses a unique and very user friendly way to access different sound bytes making it easy to build “talking” devices. It can work with words, complete sentences, or use it to add sound effects.
This is the shield John Park used in his audio sampler + joystick build video.
