"Peggy," - A Light emitting pegboard display
Evil Mad Scientist Laboratories have released "Peggy" this is a great open source hardware project for LED art makers! -
With all the cool things that you can do with LEDs today, there is still one thing that's lacking: simplicity. If you want to run a bunch of LEDs at a time, you usually end up spending a fair bit of time worrying about series and parallel combinations, matching brightness, and picking load resistors. Or, if you're a beginner, maybe you only get one third of the way through the previous sentence-- wondering if you're already in over your head.Evil Mad Scientist Laboratories - "Peggy," - A Light emitting pegboard display Link.Suppose that you want to make a big LED display for your window or wall: maybe it's your logo, a symbol, your favorite 8-bit character, or maybe even a sign that spells out words like "OPEN" or "ON AIR." How do you go about it? The usual DIY solution involves drilling holes in a panel to fit your LEDs, then spending a heck of a lot of time wiring everything up-- ending up with one resistor per LED (and a three-dimensional mess if you happen to look at the back side of the panel). And, if you do everything in the most obvious ways, it can even end up consuming a surprising amount of power.
While I have certainly spent my share of time constructing things with the aforementioned technique, at some point it becomes clear that there has to be a better way. In this day and age, shouldn't LEDs be about as difficult to play with as, say, a Lite Bright? Today we are releasing a new open-source hardware and software design that takes some of the sting, complexity, and mess out of playing with LEDs. It's a versatile and powerful light-emitting pegboard that lets you efficiently drive hundreds of LEDs in whatever configuration you like, without so much as calculating a single load resistor.

Fuzzy logic guitar effects pedal
Here's a unique circuit for guitar effects builders. It uses readily available SIP sockets to allow easy transistor swapping. Experiment with different values for a personalized sound - and change it up on a whim. You can also recreate a bunch of popular pre-existing fuzz distortions with it:
Some of the fuzzes you can make after building this layout are the Basic Fuzz Face (with R.G. Keen Mods, Roger Mayer Mods, Fuller Mods), the Vox Tone Bender 5/67, runoffgroove.com's Sili-Faces, fuzzcentral.com's Axis Face Germanium and Silicon, Joe Gagan's Easy Face, Aron Nelson's Hornet, the Gus Fuzz Face, Tim Escobedo's Many Faces, the Boutique Fuzz, and the Miss Piggy.
Guassmarkov's site has some great tutorials on using op-amps and other basic electronic parts. There's a boat-load of schematics, PCB images, and Eagle CAD files on there as well.

Pocket Electronics - MIDI controllers, including the MIDI gun!
Check out the great gallery of projects that used this MIDI controller kit -
Pocket Electronic (abbreviation: "PE" in the following) is an universal electronics DIY kit to built your own MIDI control box. Up to 16 controlling elements can be connected to PE transmitting 16 different MIDI messages on different (or even the same) MIDI channels.Pocket Electronics- Link.Essentially it contains the electronics core of Pocket Control resp. Pocket Fader but without the 16 controls (i.e. without rotary potentiometers resp. faders).
Instead of this PE is used to connect up to 16 controlling elements (e.g. rotary potentiometers, fader/slider potentiometer, touch switches, toggle switches, foot switches, foot controllers). The controlling elements are not included but have to be added by the customer. The MIDI data range is 0...127 with 7 bit resolution.

Parallel port logic analyzer
Adrian posted a step-by-step tutorial on how to build an inexpensive logic analyzer for your PC. He even has the schematics and software to download. Having an oscilloscope or simple logic analyzer can save you a lot of time when troubleshooting your electronics project.
A logic analyzer is a like a recorder for digital signals. During a certain (small) period of time, the state of a few digital lines can be recorded to a file. An event can be specified to signal the start of the recording, i.e. line 1 toggling from 0 to 1.
This looks like a really easy way to view some logic signals, but I would be a little concerned that the test probes are not isolated. You've been warned! - Link [Via]

MovieBeam hardware and software hacking...
Here's a wiki dedicated to opening up the MovieBeam player, a Linux-based set-top-box recently obsoleted by the demise of the MovieBeam service -
The MovieBeam service was a unique system for delivery of movie rentals to the home. It was based on a set-top-box using a special over-the-air data receiver, a hard drive and secure playback software. The terrestrial broadcast data transmissions would continually "beam" new movies and promotional material to the box where they would be stored for subsequent playback. The system would keep somewhere between 80-100 titles on the hard drive available for instant rental. While some of the hardware is quite specialized, the underlying system runs a variant of the Linux operating system and theoretically the box can be used for other purposes than its original design.MovieBeam wiki, thanks Dexter! Link.Purchased by Movie Gallery in early 2007, operations for the MovieBeam service ceased on or about December 15, 2007 and their website went down shortly after that. Inquiries with what was left of customer support regarding what to do with the player were met with "you can do as you please with the player." This wiki is intended as a repository for information regarding hacks and exploits on the MovieBeam player in the hopes that a few of them can be saved from a landfill.

The muio interface
Interesting project, any maker use it?-
The muio interface is a modular system for sensing and controlling the Real World, from programmes such as Pure Data, MAX/MSP, SuperCollider, Processing or something you have written yourself.There are several interface controllers around now - some others are even OpenSource. They all have their pros and cons. However.
- The muio needs NO PROGRAMMING.
- The muio needs only 2 readily available chips to get started.
The muio interface is an I2C to USB hardware device, based on USBIO from Delcom Engineering. I2C is a standard protocol that is popular within robotics. There are several ready made chips and circuit boards that are i2C compliant. These can be ready connected to the muio and are controllable once you know the operation codes for that particular device.The muio interface, thanks Steve! - Link.

HOW TO - PCB pre-order check
uCHobby has an article up about checking component placement on PCBs before ordering. If you're planning on having your circuit design professionally fabricated, it's vital to do a thorough pre-check to get a better idea of the final product. There's not much worse than receiving a box full of expensive custom green coasters (unless of course you're into designing coasters) when you expected a functional board.

Radio control switch from junk
This is a great way to recycle those old cordless phones into something really useful and in only 5 relatively easy steps.
Here we are going to make a simple radio controlled device using supplies from your local dumpster. This project should cost less than a dollar to make. If you spend more than a dollar on this project, you need to dig more.
