Low cost electronics lab equipment

In the past I’ve had good luck purchasing inexpensive elecotronics lab equipment such as autoranging digital multimeters from and would still recommend them but another option has come to my attention. In reviewing some of my literature from the January Consumer Electronics Show (read: working on the backlog of work on my desk) I stubled across the website. To be sure these folks specialize in meters and a few power supplies, not the broader range of equipment that Circuit Specialists has, but if you need to outfit an electronics lab, shop or just yourself with a handy digial multimeter they may be just the ticket.

Simple DMX Signal Locator

If you spend much time involved with lighting in a production environment you can understand how useful it can be simply to know if DMX signaling is present at any given location. Luckily, on the internet you can find instructions for building your very own simple DMX tester. As desribed this “keychain DMX tester” will test for the existance of DMX signal voltage and signal polarity. While not especially complex, this simple pocket tool is bound to come in handy if you spend much time troubleshooting DMX lighting control.
