Have a look at the TechDweeb, Univac has made a circuit bending mod to a Staples easy button. There are samples of the effects on his site also.
Bent Staples Button (listen to more)
Download EasySlo.mp3
“This is a terrible Staples Easy button (”That was easy!”) that I added a 1Meg pot to control pitch way way down until it now sounds really quite interesting, in a grainy, annoying, girl-killer-frequency (you know what I mean…) kind of way.
It was a very simple bend. Removed one resistor (there were only two) and replaced it with the pot. The hard part was fitting it inside the case. I ended up cutting a chunk out of the board that was just ground traces, put in the pot, then jumper wired the ground back together. It all fit nicely after that. And looks good too.”

If you are wanting to make circuit boards using the UV exposure method you may want to recycle an old scanner into your UV light source.
“I opted for 3 tubes (around 8 Euro each), with ballasts and starters (6/7 Euro for each set). The switch, fuse holder and mains socket I scavenged from somewhere.
For the bottom plane I used a tin sheet. This acts as a sort of mirror/diffuser for UVs.
I used also some scrap aluminum bars from kitchen furnitures, their colour in the pictures tell it. Spacers and screws as required.
Now, the pictures show the electric diagram and the interior of the UV bed.
The circuit is based on three TL5 8W wood light tubes. Each tube is powered by its own ballast and starter . The number of tubes can be increased at will. The circuit is provided with a safety fuse and a power switch. A power socket […]

Looks like less is more when trying to master flight. This small helicopter is using a brain that is based on the brain of an insect!
“As tiny as insect brains are, they can still perform extraordinary acrobatics in the air that human flying machines have yet to match. Now scientists reveal a miniature helicopter, with an electronic brain inspired by insects, that could help lead to better takeoffs, flights and landings for robotic aircraft.
Insects and other animals capable of powered, flapping flight are somehow able to execute controlled takeoffs and landings and keep flying at proper altitudes despite their lack of the sophisticated instruments available to human aviators.
“It’s extraordinary to see flies navigate with just their small 10-milligram brains,” said researcher Nicolas Franceschini, a neurophysiologist and engineer at France’s National Center for Scientific Research and at the University of the Mediterranean in France. ”

This instructable shows how to build your own RF probe. The parts needed might already be in your parts bin!
“Probe for measuring in the Radio Frequency range built inside an earphone jack, designed to have minimum capacitance and complete shielding.
What is needed:
A diode. Germanium point contact, OA79 or 1N34 is the preferred and traditional choice. But a modern substitute will be a schottky (gold bonded) diode. These have a low forward voltage, below 250 millivolts or so, versus the 600 or so of the silicon diode.
A few capacitors, chip type, value not critical, around 1 nf to 100 nf. (or 1000 pf to 0.1 microfarad)
One resistor, 1 Megohm.
One stereo earphone jack.
One pin from a turned pin IC socket. This forms the ‘hot’ end of the probe, so that various pins can be inserted for probing. A short piece from a needle for exploratory work. A piece of wire soldered […]

Ever wonder how induction heating worked? Me too… Penguin Labs has an informative article about some of their experiments.
“Induction cookers, furnaces, stoves and all that jazz are now widely used. You put your metal saucepan on top of an innocent looking glass plate and it magically heats your food with no flame and almost no waste heat.
They are able to heat certain metals up to their melting points, and that is very hot, obviously…
How they work?
When an alternating electric current is passed through a coil, the coil creates a magnetic field. The magnetic lines of flux cut through the air around the coil. If a ferrous material, such a solid bar of iron is inserted into this coil, certain effects known as eddy currents are induced to flow in the metal bar. This causes localised heating, and ultimately heats up the metal bar.
A hexagonal screw in the red hot zone. […]

This RF Remote Controller project is very well documented and even has a step by step explanation of what the PIC microcontroller code is doing line by line!
“On these pages, I will introduce Remote Controller with Radio Frequency. The electric wave sending-out is controlled with the code by PIC for transmission and the code is deciphered by PIC for receiving.
The 2 stages FET amplifier is used for the high frequency amplification. The FET amplifies only at the voltage to apply to gate (G). The resistor to be putting in the source (S) of the FET is to make the bias voltage of the gate. When making a resistance value big, voltage of the source goes up to the grounding and the bias voltage becomes big. In case of the gain of the amplifier is big, when the signal of the output returns to the input, an amplifier oscillates. In the […]

Want to be a DJ? You can go hands on with a modified Wiimote called the WiiJ. But when you get serious the Kuka industrial robotic DJ is the only way to go!
Videos and more pictures after the jump.
“The Juke Bot is a pair of Kuka industrial robots; each is surrounded by a set of platters (you know, vinyl LPs). The two bots act independently, deftly grasping an LP, and then bringing it to a platform with a phonograph needle. Delicately, the robot presses the LP against the needle and begins to rotate it forward and backward, creating a unique performance sound.”

Part of this video that we featured a short time ago was this Hand Held Self Contained Air Cannon. Now we can see some close up pictures and a detailed description of how it was made. What will come out of the FastMHz crazy high voltage lab next? We will have to wait and see…
“This is a relatively simple device bodged together from junk I had around. Take some PVC parts, an old tire inflator, solenoid, capacitor, inverter and various other stuff.
The design consists of a tire inflator compressor strapped to a PVC air chamber. In the rear the air goes in via the fittings seen below. The air is released from the front via a solenoid…it’s rated 48v…but it won’t trigger with 100psi at 48v, so I rigged up a capacitor to feed it 200v or so for a split second, enough to shoot perfectly. The short duration […]

Transform your old scanner that is just collecting dust in the closet into a cool tech lamp.
“This instructable shows you how to make a desk lamp out of scrounged scanner parts and a few extras from Home Depot. I have set up a small solar array, controller and a storage battery. I wanted to make some low power lighting that I can use in my office that would not consume a lot of power. I had a bunch of scanner parts lying around and decided to put them to good use.”
Thanks Joe P.

Have a look at the parts list below. It doesn’t take much to make your own shake light!
“Make magnet tube:
This part could really be made from anything (i.e. stiff paper), I used the pen because the magnets just fit inside the tube. Cut your tube a little smaller than the length of the Tic-Tac box. Find some washers or plugs to use as end caps, these could also be made out of paper. Mine were plastic gears with the teeth sanded off. Stick all 4 magnets together and put them in the tube. Glue on your endcaps being careful not to get any glue on the magnets.
PARTS:
150 ft. 30 gauge enamel-coated magnet wire
4 1/8″ rare earth magnets
4 rectifier diodes (IN4007 MIC)
Resistor (22 ohm)
White led
Switch
Some sort of small rechargeable batteries
Ballpoint pen
2 plastic washers or doodads
Tic-Tac container
Hot glue
Epoxy”

Here is an digital audio project that uses S/PDIF.
“Here’s a very trivial S/PDIF transmitter hack for portable MiniDiscs and other digital audio devices lacking S/PDIF output.
The s/pdif transmitter runs from +5V, 44kHz 16bit input at 384xfs, is set to consumer mode output, and doesn’t transmit any COPY bit (copyright protection disabled). The board can be connected directly to a PC motherboard, or via a Toshiba TOTX173 to an optical cable feed, or with a small transformer to a coax line.”

Hacked Gadgets friend FastMHz has been busy doing all sorts of experiments, and this crazy mad scientist has captured it on tape for our enjoyment! Not sure if all fingers and toes are still accounted for, I think I would be hiding (cowering) behind something solid for most of these tests.
After watching the video those wall mounted can crushers seem so useless, I want to crush cans using a huge electrical discharge! I also have never seen a water capacitor, hopefully FastMHz can fill us in on how to build it and how well it works…
“I’ve just finished a new video my handheld air cannon, an electrothermal cannon (first one I’ve ever seen by a hobbyist), and exploding wires, along with another use for the induction launcher…also got some high power single stage coilgun shots in there…”
