Andrew Holme built this incredible four-channel GPS receiver using a repurposed FPGA board from a previous frequency synthesizer project. Connected to a PC running a console app, Andrew’s receiver is capable of tracking four satellites simultaneously, which is good enough to capture lat, long, and altitude.

Um. Wow. It’s attributed to MOCPages member PLUM B, and here described by The Brothers Brick: “[F]eatures a clip-fed firing mechanism that shoots rubber bands – perfect for taking out the paper Locust horde. If that’s not enough, the saw blade on the front of the gun is motorized for slice and dice action.”
The XBee XB24-Z7WIT-004 Series 2, from the Maker Shed, improves on the power output and data protocol over the Series 1. It takes some time to set up the ZB family of modules but when you do they allow reliable point to point, mesh, and compatibility with other ZigBee compatible networks.

Check out this quick way to add a durable grip to your favorite tool using heavy gauge wire and some heat shrink tubing.
Sébastien Bourdeauducq of /tmp/lab visited PWL, a “one-man vacuum tube laboratory” headed up by Aleksander Zawada. He starts the triode by assembling the grid. To do this, he takes a piece of nickel wire, and soldered a small spiral of molybdenum wire on it – one turn and one solder at a time. He uses […]
