Jro writes – “This project modifies a $5 Staple’s Easy Button and an inexpensive USB keyboard so that they can be used as an input device for live musical performances (or anything else that requires a button or footswitch). It alllows cheap buttons to be created that each send a keyboard character as input to […]
Kevin writes – “I have been searching for a good way to connect a Nikon D200 to a GPS in order to geocode photos. I have not found a solution that I thought was near a reasonable price. I have therefore made my own. I made a project page for it and posted it for […]
Ben writes – “I love analog gauges, toggle switches, and other retro technology, so I had to find something to do with my small collection of antique gauges. The result is my PIC-based analog gauge controller, which takes serial data and displays it on the gauge. Right now it’s displaying CPU usage from my PC.” […]
MrMunki has a good Instructable on making a super-compact 9 volt USB charger, he calls it a YAN9VUSBC (Yet another 9 volt USB charger) and besides its small form factor, the name is why I really like it – Link. Related: MintyBoost! – Small battery-powered USB charger – Link. 9V USB Charger Kit – Link. […]
EiED’s William Wong has an extremely thorough article on building a multimedia home control set up, he writes – “Home multimedia centers are popping up at stores but most are relatively closed boxes or are full blown PCs. Of course, engineers like myself love to get under the hood so this project is about building […]
Steve writes – “Here’s my latest oscilloscope project, this time utilizing a graphical LCD…The oscilloscope measures the average voltage, the maximum voltage, the minimum voltage, the peak-to-peak voltage, and the zero-crossing frequency for a DC signal over 100 samples. The oscilloscope has a built in edge trigger function that can be set to capture on […]
Here’s an older-ish how-to on making quick prototyping modules, Jeff writes – “For years I have had a need to quickly create electronic circuitry for experimentation. Like most other people I have gone through all the stages. Wire-wrap, soldering point-to-point, pluggable ProtoBoards. I have tried various methods for making my PC boards. Iron-on transfer, plotting […]
