This weeks PAW is something that I have wanted to have for a long time but never gotten around making – until now that is 🙂 Everytime I solder a SMD LED on a pcb I have to turn on one of my multimeters and flip it over to diode-test mode and then probe the […]

Over the course of the last 5 months I developped an application to visualize Gerber data. The goal was primarily to review Gerber files before sending them to a PCB fabrication house. It is very similar to the Mayhew Labs online Gerber viewer, except it’s offline (and has a few different features). My tool is

You’ll be the talk of the town when you wear this obnoxious, oversized, completely impractical wristwatch. Display your favourite foul language, song lyrics, prime numbers, etc. Inspired by the Microreader kit, I decided to make a giant watch using similar sixteen segment displays. Twelve hours later, I came out of my masochistic fugue and stopped

The TS3004 is a single-supply, timer IC fully specified to operate over a supply voltage range of 1.55V to 5.25V while consuming 1.9μA supply current. Requiring only a resistor to set the base output frequency (or output period) at 25kHz (or 40µs) with a 50% duty cycle, the TS3004 timer/oscillator is compact, easy-to-use, and versatile.

What follows are instructions for constructing a battery powered portable VU meter, as well as detailed instructions for the construction of the PCB needed to complete this project. It was designed to illuminate from 0-10 LEDs depending on ambient sound levels. I designed it to be attached to a wristband, clothing, or a necklace if
