In past articles I have shown how to control dc loads with a logic level MOSFET, but did you know you can control AC loads as well, just indirectly? The attached image shows the circuit diagram, and the MOSFET code
Testing the first batch of WHEM boards, I discovered a mistake in one of the traces. Out came the rotary tool, and I ground out two trace connections, and soldered in 2 jumpers. This will be corrected on the REV
Our board design for the whole house energy monitor just went to production, boards should be here in about 2 weeks (See update). We made this a through-hole design for ease of assembly (kit version) and modification. Complete kit consists
You probably have read instructions about burning images and special software needed to create the sd card to boot your Raspberry Pi, but none of that is needed. Grab a 8GB+ SD Card, and follow along with this simple, easy
I’ve been a big fan of Simon Monk for quite a while. Whether it’s his Arduino evil genius books, or his electronics “courses”, It’s always educational and fun to read. This time, Simon takes us on a updated journey through
We are working with an organization that provides adapters and converted equipment to announce status messages by speech instead of visually. We have speech enabled shop measuring equipment like calipers, micrometers and dial indicators, weather stations, and thermostats, and are
