I received my Mini 7-Segment Clock PCBs. I’m pretty excited to put one together. I think it’s going to look pretty cool, being so tiny. I’ve always liked 7-segment displays. With the popularity of LCDs, TFTs, and touch screens, etc, you’d think these displays would be obsolete by now. If you keep an eye out […]

My E-Paper boards finally arrived. They look awesome. I totally nailed the cutouts for the e-paper display. They’re perfect. The ribbon connectors on the display fit nicely through the slots. They clip right into the breakout board, which is perfectly aligned over the holes for the 7-pin headerThey clip right into the breakout board, which

This article shows you how to build a very simple FM transmitter from thirteen components, a Printed Circuit Board (PCB) and a 9v battery. This project was designed to be mounted on a PCB, however you don’t have to. You could construct the project on Vero board (strip board) or any other 0.1” pitch style

To reach a maximum mechanical stability, many Sonitron piezo components are now available even with a foam tape. Sonitron piezo components feature a high reliability, resistance to harsh conditions and also to vibrations. Despite these features, usually one of the weakest points (as for the vibration-resistance) is the joint of leads with a PCB. That´s
