“Dl” for PA and słudios

If yoiTre into professional audio, you'll find our new design for a "direct injection" unit of great interest. It features Iow power consumption, "phantom" powering via the balanced output linę, and (best of all) a cost well below commercial units.

Plain vanilla data modem

For a lot of data modem applications, you don’t really need all the fancy frills like auto dialling. Our new modem provides all the basics for 300/300 baud and 1200/75 baud Communications, at a rock bottom price. It’s easy to build, too!

Continuity & voItage checker

Here’s a really useful little gadget for tracing wiring in buildings, vehicles or boats — and also for identifying which wires are "alive”. It's easy to build, and wili cost you a lot less than commercial checkers.
