I thinks this Arduino ProMini is the cheapest and smallest board with full capability based on Arduino.
The Arduino Pro Mini is a microcontroller board based on the ATmega 328P from Atmel (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board 16Mhz resonator, a reset button, and holes for mounting pin headers (2.54mm). A six pin header can be connected to an FTDI cable.
The board comes only with holes (with 2.54mm spacing), without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires.
The pin layout of the Pro Mini board is compatible with the Arduino Mini.
This version of Arduino runs at 5V and 16 MHz, but it has a raw power connector where you can add power supply from 5V up to 12v (DC voltage!).Read more: Arduino Pro Mini

400Plus firmware hack for Canon 400D DSLR (aka. Rebel XTi / KISS Digital X), new tricks for your old DSLR.
Searching for custom firmwares for Canon DSLR's like Magic Lantern, I found an interesting firmware enhancement 400Plus, which offers additional functionality and capabilities to my old 400D (aka. XTi) camera.
400Plus it works by loading into your camera's internal memory automatically upon boot-up from the compact flash card to enhance the native camera firmware. Is not a permanent firmware upgrade, the original firmware remains unchanged and can easily be removed form the CF card.Read more: 400Plus

PWM (Pulse-width modulation) can be implemented on the Arduino Diecimila and Duemilanove in several ways:
- Bit-banging PWM
- Fast PWM
- Phase-Correct PWM
- Fast PWM Mode with OCRA top
Pulse-width modulation is a way of encoding a voltage onto a fixed frequency carrier wave (like on FM or AM radio)
Writing a value from 0 to 255 on a Arduino PWM pin, will cause the pin to output a PWM signal whose on time is in proportion to the value written, a value of 255 will be 5 volts on the PWM pin.
Becouse de power limitation of the Arduino PWM pins, I used in my schematics 2pcs of BD139 power transistor, one for every fan.
To protect PWM pins from the higher voltage (12v DC) I used an two channel optocoupler (LTV-826)
The schematics of this Arduino PWM shield is very simple, and anyone can build it. You can download all the project files you will need it hereRead more: PWM Arduino

After my unibody Apple A1342 died, no longer turns on I removed the internal Isight webcam. I want it to use it later on my desktop pc via USB cable.
After my isight webcam been laying around. I thought I splice up the cable and connected to a USB connector.
The GND and the 5V (power) signal you can detected with a simple voltmeter.
I couldn't believed what just happen. On the second try I got it right, the webcam works perfectly and sends clear images to my desktop PC.
Plugged it in an USB port and instantly recognized my WIndows 7 64bit as Isight webcam without additional driver.Read more: Isight pinout

This led driver (constant current source) eliminates changes in current due to variations in forward voltage of the led, which result into a constant LED brightness and longer life span.
If you forget to use a led driver in your DIY led lamp \ light project is very risky, you can burn the high power led.Read more: Led driver for high power Leds (10watt)
