Today TAPR announced availability of a project I’ve been working on for a while, a computer-controlled switch system called the TASS. It consists of an 8-port relay bank that handles from DC to 150 MHz, a shield for an Arduino, and open source software for the Arduino. You can order the boards from http://tapr.org/kits_tass.html.
I also designed an enclosure for a TASS board plus touchscreen controller, and had that built by Front Panel Express. Here are some pictures of the finished product. The enclosure wasn’t cheap; even in quantity it wouldn’t be cheap. But we’re thinking about offering a one-time group buy. Contact me if you’re interested.
