The $5 drum machine
MedCosm writes -
I thought it would be a neat to build a toy that records and plays back beats like a simple drum machine. For those who are musically inclined, it provides endless hours of entertainment and even has practical purposes in learning and practicing music. Even better if it used less than $5 worth of parts and could be built in 30 minutes.Here is such a toy.
Turn it on. The LED glows indicating it is in record mode. Tap out a beat and the controller records your beats. After sample memory is filled up (about 5 seconds), the LED goes out and the beatbox goes into playback mode, endlessly looping playback of your sample. Press the drum pad again and you're back in record mode again. Finally, a chance to put that finger-drumming to good use. And if you continue finger-drumming along with this $5 beatbox, you can easily tap out some very complicated rhythms.
The $5 drum machine, Thanks Chipwich! Link.

HOW TO - Make a bluetooth banana phone wireless handset
Scottredd writes -
This project describes the steps involved to construct a working Bluetooth handset in the shape of a banana.The premise is to permanently embed a Bluetooth headset inside of a fake banana, while exposing the necessary sound holes and USB port for in-place charging.
In practice, it took some time and patience to place the headset such that it remained functional inside of the banana.
One thing I would do differently would be to extend the length of the microphone wires so that I could increase the distance between the earphone and the microphone, and to insert some sonic insulation between the earphone and the microphone, as my finished banana phone gives a terrific echo back down the line to the remote party.
I apologize for the low quality of my photos. I recently "bricked" my digital camera by leaving it outside in my vehicle during some of Nebraska's coldest days. The photos in the instructable were taken using the camera in my LG Chocolate phone.
This project was inspired by the DIY Banana Phone at Make Magazine, as well as the Bananaphone song by Raffi and remake by Rhonda Vincent.

3D & joystick controller for DTV/Commodore 64
D. Garmon has a great how-to on making a 3D & joystick controller for DTV/Commodore 64. Source and schematics on the details page -
The DTVii is a wireless tilt controller and joystick for Commodore 64 compatible computers. The parts for the project are fairly common and were not terribly expensive. A pair of Atmel AVR microcontrollers, each coupled with a transmitter and receiver form the core.DTVii project page - [via] Link.

Cheap and easy toner transfer for PCB making
Hilarycheng writes -
There are lots of people mentioned about using Inkjet Glossy Paper to do Toner Transfer. It can be done. But it is not easy to remove it after ironing. You have soak the PCB in hot water for more than ten minutes. It is quite time consuming. If you cannot remove the coating completely. It cannot be etched.I have tried to use Konica Minolta Photo Quailty Matte Paper. Then design your own circuit and print it on the Matte Paper. Remember, before printing it. You need to mirror board. Otherwise, the circuit will be inversed.

EyeWhere - electrooculargram (EOG) kit
Interesting PIC based project that can use your eyeball to move a mouse around -
EyeWhere is an electrooculargram (EOG) that will allow your eye position to dictate the position of a cursor on a computer screen.At the moment, only the schematic, parts list, and PCB patterns are available. The price is $19.95. The total cost for the parts is approximately $75. The parts are not available here. If you wish to order the parts, you should check an electronic component vendor such as Digikey.

HOW TO - UHF oscillator
Neelandan writes -
I am assembling this to find out the limit of oscillation frequency of a transistor from my junk box. After it is completed, it shall be used as a signal source for some uhf circuits.The frequency of the oscillator depends upon a tuned circuit - a parallel connection of an inductor and a capacitor. I shall not use a separate capacitor, depending on the capacitance of the wiring and the internal capacitance of the transistor for this function. The inductor shall be made pluggable, so that I can use successively smaller inductors until the circuit stops oscillating. The smallest inductor which still allows the circuit to work should produce the highest frequency.
For supporting the inductor, I am using a small scrap of board soldered at right angles to a larger piece, and supported by struts of connector pins soldered in. The sockets shall be pins extracted from an IC socket. The components shall be placed close together to minimise inductance so that the highest frequency may be attained.
It all starts with a circuit diagram - I have alloted about two thirds of the supply voltage as Vce and around 5 ma of collector current with a supply voltage of 12V.

HOW TO - RFID Enable your front door (with a Parallax BASIC Stamp & 13.5 MHz APSX RW-210)

I decided to try and improve the reliability and responsiveness of my previous RFID front door project (based around a client / server design), by re-implementing it using the Parallax BASIC Stamp 2e, and the 13.5MHz APSX RW-210 RFID reader as a standalone device.

7 years of portable console modding
Ben Heckendorn's has been making amazing portable console systems (like the VCSp) for 7 years, check out post about this and the rest of his work -
It was 7 years ago (ish) that I completed my first video game portable - the original VCSp. How do I know this? Well I had it sitting in the car, newly done, as I went in to get my taxes done (always at the last minute) and I was worried someone might steal it. And I recall sitting there looking at it and thinking "Damn that thing looks good!" To this date it remains the only portable I've ever kept for myself.

Electronics tutorials
Alex has a great series of electronics tutorial, he writes -
Welcome to the electronics tutorial! If you want to learn electronics, it's a great place to start. You can also revise for your GCSE here, as it's written to GCSE standard for the year 2000 (so if you're taking it in 1999, forget it. but have a look anyway!). It's suitable for all, and anyone can learn electronics using a combination of this & the other material available on my site. Whether you want to learn as a hobby, are taking a course in it, or just want to brush up on a few points, there should be something here to help you.

Complex stereo sound generator for sound effects and music synthesis
GetLoFi spotted a pretty interesting looking sound generator kit--
...Saratronics company based in Switzerland is selling these new Complex Stereo Sound generator kits for around 35 Euros shipped. My guess is that they are very similar to Soundgin modules, except a heck of a lot better. Typically modules like this are controlled by serial commands through an interface with a help of a PIC or AVR microcontroller that triggers the digital input pins of the generator. When those are shorted in a particular order they turn off and on various chip functions. The main sound generating IC in this case is SAA1099P,which I have never heard of, but apparently it packs quite a wallop...

Shallow box access panels and digital photo frames...
MAKE Flickr photo pool member Chrisdigo writes -
Digital Picture Frames are great to display a picture slide show. It can be put on a table, desk etc. but also can be hanged on a wall, just as a regular frame. But in this case, how do you conceal the AC power adapter cord ?The electric box manufacturer Carlon has in his catalogue a "shallow box with access panel" ref B117RSW. It was designed for old electrical circuits and you can find it at your favorite home improvement store. I used this box (after some Dremel adjustments) to conceal the AC power adapter in a shallow wall, along with some crimp spade to tap on the 110V power outlet.
Some will argue it is a safety hazard since the AC power adapter is concealed and it may overheat. I'd like to have your feedback on this, but c'mon it's only 9V and it doesn't heat at all.
Note: For LCD TV and bigger frame, you can use the Leviton REB - Recessed Entertainment Box - for the same type of results.
