$35 AVR Oscilloscope clock kit
This is fantastic looking kit, turn an oscilloscope into a clock!
Is your X-Y capable analog oscilloscope underutilized? Make it show the current time! Need a clock for your GPS receiver? Use your scope! This AVR Oscilloscope clock is available as a kit, using all through-hole components. The kit included ALL components necessary to assemble the board shown below, including a preprogrammed ATmega168 microcontroller. It does not include an oscilloscope. It also includes connectors for the Power and RS-232 headers on the board. The user can use these connectors to build the power and serial communication cables.AVR Oscilloscope Clock - [via] Link.

Make a wire storage tower
Evil Mad Scientist Laboratories shows you how to make a wire storage tower -
If you accumulate project material like we do, you've probably got a heap of half-empty wire spools from junk shops taking up space in a box or on a desk. We've got a simple solution for you: a small flat piece of metal or wood, some tape, some felt feet, and a rod.Evil Mad Scientist Laboratories - Make a Wire Storage Tower - Link.

DIY AVR based MP3 player

Bozai writes -
This is one of my DIY works. It uses a mp3/wma/wav/mid decode chip VS1003, ATmega8L and SD card. It supports various bitrate music file. Supports both FAT16 and FAT32. For the reason of space, resource the screen was not added. But a couple of LED were used to indicate the state.:: AVR Freaks - (free reg' required) Link.

New stuff @ Spark Fun Electronics
Spark Fun has a few new items of interest, if you dig on electronics...
Color 24-Bit LCD 4.3" PSP 480x272. Looks like some SFE fans found this device before we could even get it noted on the home page! This is an original 24-bit color LCD from Sharp. Does it look familiar? It's the same LCD that goes into the PlayStation Portable (PSP)! So snazzy - we can't wait to get one lit up. We've also got the connector available for it - Link.
Ambient Light Sensor - TEMT6000. Here's a neat little component. This is the TEMT6000 ambient light sensor. This sensor detects light levels in the surrounding environment. A simple but effective way to interact with your next project - Link.
Quad-band Cellular 9" Antenna SMA. This is a giant 9" quad band cellular antenna. Great for those AVL applications that need good reception in poor cell areas - Link.

Vents for project cases
Vanya writes -
For most of the electronics projects I build for fun (power supplies, function generators, code keyers, 555 timer circuits, etc.), I usually just head to the local Radio Shack and buy one of their cheap plastic project cases. Unfortunately, these cases don't have vents or fan ports, a desirable feature to have with circuits that dissipate a lot of heat, so I have to "drill my own". I've since developed a quick and accurate technique to create these vents that others might find useful.

The Retractable alarm clock
Colleen and Vincent's AVR based alarm clock (source included) --
Alarm clocks are essential in almost everyone's daily life. For most of us, we start our day to the sweet noise of our alarms. While some people wake up instantaneously to the first chirp of an alarm, some struggle everyday to get out of the bed. The Retractable Alarm Clock is the next generation alarm clock that combines both active alarm feature and penalty system that trains the users to wake up to the alarm over time. The clock in this projects consists of a head unit that is to be hanged on the ceiling above the bed and has a retractable snooze button which hangs to reachable height above the bed. When the user snooze the alarm, the snooze button moves up, promoting the user to physically get up and to snooze the next time.

The X-ray Eye (X-Ray of PCBs)
Bunnie writes -
I love looking at PCBs (printed circuit boards) using x-rays. Great for failure analysis. One of the coolest things, I thought, was seeing a PCB tilt in real-time; you get a good sense of the actual spacial relationship between all the layers on a PCB. I took a series of stills today and strung them together into this animation so I could share the experience with you...

Maker Faire: YBox in 60 Seconds
The Ybox is an open hardware and software spec for an IP-enabled set-top box in a candy tin. Josh and Tarikh will give away 80 Ybox kits and lead 4 free workshops teaching folks how to build them. Josh Rooke-Ley and Tarikh Korula are the founders of Uncommon Projects, an interactive design studio based in Brooklyn, NY. They created the YBox for Yahoo's Hackday 2006 where it placed 2nd. Yahoo has sponsored them to gift their project to Maker's Faire attendees through free kits and workshops - Link.

The secret life of pots
R.G writes -
As electronics tinkerers, we all use potentiometers, or "pots" for short. We count on them to control all our musical gear, and quite often get frustrated by their limitations. As in all relationships, a little understanding goes a long way. Let's take a look at how pots work so we can use them better.Back in the dim reaches of electronic prehistory when electricity, let alone electronics, was poorly understood , a number of researchers were trying to figure out how this mysterious force worked. They had no meters, no oscilloscopes, not even very good batteries, and had to literally make their own parts to get anything electrical to work. In this era, a fellow named Ohm settled a controversy...

Batt-Mon (battery monitor)
Mark made a really nice battery monitor, he writes -
This mini-project came about from building a garden shed. I wanted to use an old UPS battery and some spare halogen downlighters for illumination. As I researched lead-acid technology, I decided that I needed more than a simple switch if I wanted the batteries to survive.One of the biggest problems is deep discharge - in other words allowing the terminal voltage to drop too low. A Yuasa data sheet (for a NP10-6 battery) specifies the expected number of cycles verses the depth-of-discharge - for 100% DOD, you get 250 cycles, for 30% DOD, you get 1200. Unfortunately, the data sheet doesn't expand on the full meaning of DOD, but it essentially translates to terminal voltage.

Solid freeform fabrication: DIY, on the cheap, and made of pure sugar
Jeez, I was -playing- around with some 3D sugar modeling and Evil Mad Scientist just totally demolished me in the sweetest way possible...
In February we gave a sneak preview of our project to construct a home-built three dimensional fabricator. Our design goals were (1) a low cost design leveraging recycled components (2) large printable volume emphasized over high resolution, and (3) ability to use low-cost printing media including granulated sugar. We are extremely pleased to be able to report that it has been a success: Our three dimensional fabricator is now fully operational and we have used it to print several large, low-resolution, objects out of pure sugar.

Low cost Piezo film blood flow pulse sensor
The Phoenix Ambulatory Blood Pressure Monitor Project is a piezo film blood flow pulse sensor, very cool -
The purpose of the piezo film pulse sensor project is to identify and build a reliable, low power, low cost blood flow sensor. The sensor is intended for two proposed designs for the ambulatory blood pressure monitor (ABPM). They are: (a) an oscillometric cuff design (as a Korotkoff sound sensor) and (b) the blood flow velocity design.
