This project is a wireless temperature and humidity sensor with USB interface based on obdev’s RemoteSensor example and their firmware-only USB implementation. The main change is the replacement of the analog sensors with a Sensirion SHT11 digital temperature and humidity sensor. The sensor unit consists of an ATTiny45 microcontroller, a SHT11 sensor, and a hoperf RFM12 868 MHz transceiver module. Check details on the link below.

Having a hardware interface to your favourite music / DJ / VJ software can really open up doors in your creativity. The most widespread form of hardware control to your PC for such applications is a MIDI based controller.

A MIDI controller can send and receive MIDI messages to your PC, allowing direct control of your software. Not only that, but the controls can generally be mapped to anything your like. So what might be a volume fader for one person can be an effect filter for another.

This article will describe how to build and program a custom arcade button MIDI controller, while trying to keep the price below $100. It is aimed at electronics and programming novices.

Tweet-a-watt: a twittering power meter

This project shows how to make a tweeter enabled power meter. “adafruit” used an existing Kill-a-watt power monitor.

My plan is to have each room connected to a 6-outlet power strip which powers all the devices in that room (each kill-a-watt can measure up to 15A, or about 1800W, which is plenty!). That way I can track room-by-room usage, for example “kitchen”, “bedroom”, “workbench”, and “office”.
