Bryan Mumford's inventions
Bryan Mumford has a few really interesting projects, I like "The Automatic Puny Tune Player", he writes -
The Automatic Puny Tune Player is a computerized Puny Tune "robot" that plays songs on an actual wooden Puny Tune by blowing air into the mouthpiece and opening and closing the finger holes with mechanical levers. For those who don't know, the Puny Tune is a 4-holed flute that can play a chromatic octave by fingering the four holes in different combinations.Bryan Mumford - Link.The Puny Tune Player is made from wood, brass, rubber, and acrylic. The mechanical components are mounted on top of a clear plastic sheet which covers the computer and electronic components.
To operate the machine, you turn the hand crank seen at the right side of the cabinet. This drives an oak and brass crankshaft which in turn operates three pistons in the clear acrylic cylinders. These pistons pump air into an oak reservoir chamber at the back of the cabinet. Two tall rubber bellows absorb this air and inflate as the air is delivered. When the two bellows are fully inflated, they close a switch which activates the computer, a Z80 single board controller.

The BroadWave synthesizer
This fellow is building an Arp 2600ish modular using Music From Outer Space modules, wow! He writes -
So, 17 years ago I made a huge, HUGE mistake... I sold my dearly beloved ARP 2600 in order to buy an Atari STFM (remember those?)The BroadWave synthesizer. Thanks Kaden! - Link.
I always regretted doing this, and recently thought about getting another 2600. The problem is that second hand prices are ridiculously high - one went on ebay recently for over £2,500! and the Macbeth M5 at £3,000 is way beyond my reach.
What to do, what to do??... Build my own!

Playaflies
I've only been to Burningman once and I couldn't help but look at things as electronics projects and kits - one of projects "playaflies" consisted of LEDs inside ping pong balls and then attached to wires/PVC pipe, at night when attached to a bicycle they take on the movement of the rider as they move about, it's a neat effect - here's more about them as well as how to make your own...

DIY oxygen-propane cannon
Gadgetfreak has an explosive DIY oxygen-propane cannon -
When Ed Nauman fires his oxygen-propane cannon, anybody within range of the shock wave will definitely see stars. It's been known to shatter windows 30 ft to the rear! Propane is mixed with oxygen under control of a PIC microcontroller, in a barrel made from a 330 ft³ nitrogen tank and detonated by remote control. It's even instrumented to measure the kaboom -- he's recorded 180 dB SPL (think two sticks of dynamite).Oxygen-Propane Cannon Tests the Big Bang Theory - Link.

555 chips? Bet you can't eat just one
Every wirehead knows about breadboards, prototyping board, circuit design software, and other tools for circuit designing, but what about Lifesavers, SweeTarts, and Twix components on a graham cracker substrate? It takes the "differently wired" high domes over at Evil Mad Scientist Labs to dream up the idea of modeling circuits out of candy snacks. Models of functioning circuits you can eat! Just make sure you keep a watchful eye on 'em...
"Where's my 555 circuit layout?"
"Wi'm ewing wit."
"You're EATING my schematic!?"
[Hilarity ensues.]

Bare-Bones Arduino
The prolific R. Stern writes -
I just assembled my newly-arrived Bare-Bones Arduino clone, developed by Paul Badger. How great! Not only is it perfect for embedding in projects, but the instructions Paul made to go along with it make it so easy. I wish I had a teacher like him when I was learning the basics of physical computing! I used double-male header pins (graciously given by Mr. Badger) for the digital i/o so that I can plug the BBB into a solderless breadboard or plug stuff in on top. I have three more kits to assemble. This board is much easier to deal with than the NG (that communications chip is really hard to solder), and the Atmegas come pre-bootloaded. The development of this board is a case in point for why open source hardware rocks. Thanks, Paul!My first Bare-Bones Arduino - Link & photos.

The TeslaPhonic organ
R. writes -
The TeslaPhonic Organ is a MIDI-Controlled Dual-Resonant Solid State Tesla Coil (MIDIDRSSTC). The electrical system is made up of several subsystems. The first is the MIDI input and control interface. This interface for version 2 is based on the Atmel ATmega16 microprocessor.The TeslaPhonic organ - Link.
The completed project drives a Tesla coil...

Personal powerPlant
Jabroutin writes -
The personal powerPlant is a portable device that harnesses electricity through a solar cell and hand crank generator, into a NiMH battery. The device also includes a visual multimeter that monitors the amount of energy stored. The personal powerPlant can be used to power applications up to 8V at 70 mA.Instructables personal powerPlant - [via] Link.

LED matrix clock
Hans writes -
This LED Matrix Clock is a feasability study for a much larger project I am building for my employer, Click here for a larger photo (800 x 350, 36K). The intention was to prove to myself (and my employer!) that I am able to drive an LED matrix from a PC. This is the first project I have made which is driven by a PC. The clock uses 3 B64CDM8/B48CDM8 8x8 5mm LED Matrix modules from Nexus Machines, each having an onboard MAX7219 display driver chip. These require an SPI serial interface, which I by toggling pins of the host PC's parallel port (printer port). The small software application which drives the displays is written in Delphi 5 and runs on Windows NT 4.LED matrix clock - Link.

Electronics page for beginners
Here's another beginner electronics page to bookmark if/when needed when you're start out learning electronics...
This page is for people who want to get started with electronics. The web needs a good tutorial on this subject which doesn't assume prior knowledge or experience, and since I have yet to find one, and "Find a need a fill it" is still as applicable as it ever was, this page came about. Eventually, some small projects featuring step-by-step instructions on how to piece stuff together and make it work should appear here. For now, some basic theory and fundamentals are here.Electronics - Link & cache.

Supaghettoblaster
Kari writes -
I have always been interested in electronics. Building mechanical things hasn't been hard either. Project started somewhere around year 2003 and I began the work by researching what kind of components and circuit are available and how to fullfill the requirements I had in my vision:Supaghettoblaster, Thanks Pekar! Link.* Must be mobile and use battery
* A LOT of power and volume
* Relatively good sound quality
* Plenty of bass ;)
* Party should last long enough and therefore the battery should do it as well!
* And of course it should look absolutely cool
* Internal signal source not required. Just input for MiniDisc, iPod, whatever

Convert your vintage bike light to LED power
Here's my new bike light, I enlisted the help of LadyAda (We used the MintyBoost's boost converter to get 3.3v)...
This is a quickie project showing how you can upgrade a vintage bike lamp for a '60s or '70s roadster into a powerful 1W LED light. Its much more efficient and a lot brighter!Quickie Projects - Convert your vintage light to LED power - Link.

BongoPong
Imagitronics writes -
When I first set out to learn electronics several months ago, the first kit that I assembled was the Velleman Pong kit, available at ThinkGeek and numerous other online retailers.imagitronics » BongoPong - [via] Link.I knew right away that some day I would find a way to mod this kit and make it my own. A few weeks ago I stumbled across an article on HackADay about a clever hacker who had modified his pong kit to receive input from his flexed arm muscles.
This hack got me thinking about different ways that I could interface with my pong game, but every idea seemed overdone and not very original. Friday afternoon I was driving home from the store when I got the idea of controlling the game using an Indo board (also known as a Bongo board, hence the name).

Li-ion Life Extension
Spicy Gadget Rolls has some basic tips on extending the life of Lithium-Ion (Li-ion) batteries, commonly found these days in cellphones, laptops, mobile media players, etc...
Battery Storage - If you plan on not using the Lithium battery for prolonged periods of time, then you'll want to have the charge level at 40% and place the battery in the fridge (not freezer). Storing the battery at 100% charge level applies unnecessary stress and can cause internal corrosion. On the other hand, if the charge is too low, the battery can become permanently unusable, due to battery self discharge. This is why manufacturers recommend storing your Lithium battery at 40% charge, rather than either extreme.
