NYC Resistor member Adam Mayer just posted this fantastic guide to reading the data off of old EPROM chips. To grab the data, you’ll need an Arduino Mega (or a microcontroller with 24 I/O pins), jumper cables, breadboard, and of course an EPROM to read.
One of the downfalls of using PVC pipe as a construction media is that your joints are either permanent, or they fall apart when pulled. If only there was a way to make a robust, temporary connection. Thanks to Bill Waters’ happy mistake, he discovered how to do just that by using ShapeLock (PCL.)
Here, friends and neighbors, is the eighth and final video of Engineer Guy series #4. The element of the week is called ‘plumbum’ in Latin, abbreviated to ‘Pb’ on the periodic table, and generally known as ‘lead.’ Formed into electrodes with its oxide and submerged in sulfuric acid, lead is an essential component in the ignition batteries that start cars and other gas-powered vehicles.
This winter’s open source/DIY convention has added two new speakers to their list: Jasper Nance will demonstrate her high speed photography experiments as well as her DIY Scanning Electron Microscope project. bionerd23 will talk about detecting radiation. What are the frontiers of DIY technology? The first Exceptionally Hard & Soft Meeting (EHSM) will feature presentations […]
This human-powered bot was created by Instructables user masynmachien. One of the two servo motors acts as a dynamo, converting muscle power into electricity, which runs along a wire to the other servo and makes the bot move.

Ellen Sundh’s Bad Posture belt uses an Arduino, wave shield, and a flex sensor to detect when the user slouches. If your posture needs correcting, the belt literally yells at you. How’s that for motivation?
The belt is calibrated when the user presses a pushbutton after attaining good posture. After that, he/she is free to be lambasted by this piece of wearable tech.
