Fresh hacks every day
[Greg] built himself a small indicator dial with his laser cutter, and wanted to use it for visualizing server performance and load information. Before he started using it for server monitoring however, he thought he should test out his data parsing skills on a simpler data set.
Pachube has a wealth of information that can be freely used for … Read the rest
[Oneironaut] is trying out a new GPS module with the prototype seen above. It’s a San Jose Navigation device identified as FV-M8 and sold by Sparkfun for just under a hundred bucks. That’s it hanging off the bottom-right of the breadboard seen above. They’ve packed a lot of power into the small footprint, and made it very easy to control … Read the rest
This hack is a bit older, but one aspect of the setup makes it worth sharing. Shift registers are a common component to include in a project when you need to increase the number of I/O pins available. We’ve used them to drive LCD screens before, but we never realize you could use a 595 chip to make a 3-wire … Read the rest
When you are running emulators or virtual machines it may be sometimes handy to be able to connect a serial port from the guest machine to the host machine. [Aurimas] had that issue, and also had a fun fix for that using 2 USB <> Serial adapters, but as you can imagine that is not a ideal solution, enter the … Read the rest
You can easily add Internet-based control for your Arduino if it is close enough to your server to be connected via USB. This tutorial will give the basics you need to get it working.
The gist of this method involves a webpage that includes PHP elements. When one of those elements is manipulated, a command is sent via serial connection … Read the rest
Seven-segment displays and monochrome LCDs are fine for most projects, but some things simply look better in color. [John] over at the Little Bird Electronics blog recently wrote up a tutorial demonstrating the use of a TFT LCD panel with an Arduino. The specific panel he chose was a 4D Systems 1.44” TFT LCD that happened to feature a … Read the rest
[MikyMouse] cracked open a couple different optical mice (or is it mouses?) in order to play with the data communications coming off of the chips inside. Once he figured out the protocol, it wasn’t too hard to grab the data for use in his own projects. The chip that controls the mouse is one of two he looked at, … Read the rest
