Want mobile power for your Stellaris Launchpad development board? [Philipp] was looking to add some lithium power for the Launchpad. He used an off the shelf single cell LiPo battery and connected it to the 5V rail of the Launchpad board. It didn’t work. So [Philipp] started looking through the schematics and noticed that the regulator [...]

After seeing our communications via light post , reader [Chris] dropped this handy little link in our inbox. A very good tutorial about using infrared to enable communications between 2 pic micro controllers. The tutorial covers all the parts you will need, physical wiring and schematics with notes detailing each section of the circuit. It [...]

When looking for things to write about, there is nothing we like to see more than well-documented schematics and code available for download. In the case of schematics, we realize that they can be a bit of a pain to publish. Many times we see them in the form of blurry JPEGs or humungous PDF [...]

[Scott] found the iCufflinks from Adafruit Industries pretty interesting, but he thought that the stated run time of 24 hours was a bit short. He figured he could improve the product’s power consumption at least a little bit, to improve the overall battery life. From their schematics, he placed an order for parts and built [...]

The latest project from Lucidscience.com is a simple AVR based GPS tracker. As usual, the instructions here are quite in-depth including schematics and step by step procedures all the way down to modifying cables when necessary. What we found interesting is that the GPS module he’s using is so simple. It only requires 3 wires, one for [...]

A few months back, [John] was reading an article about a simple RFID security system kit, and decided he would like to build one himself.  While many of the system’s details, including full schematics were provided, he was dismayed to find that the source code for the project was not published as it was held [...]

[Spiritplumber] has been sending us updates on a promising project he’s working on called RobotsEverywhere. We’re not completely sure if that name covers the project itself, or just the name of his group that is selling robots (and giving us schematics and source code). Either way, they have some really cool stuff. The really cool [...]

Here’s a slick version of a POV globe(google translated). Created by [Riko], this globe has 32 LEDs and is powered by a rotating coil. The layout looks fairly solid in operation, with the POV effect showing up very nicely on camera.  You can get the schematics and source code from the project page. We found [...]

When doing those cool liquid droplet splash pictures, you need to time not only the camera, but the droplets themselves. This project takes you through how to build the system to time the droplets and work with camera axe to get the right pictures. PCB files and schematics are available. As you can see, the [...]
