I want to make a spot welder for battery packs or other stuff that cannot be soldered.

Plug in a device to your computer, push a button, and things happen! Several different modes do useless things with your mouse/keyboard.

FreeRTOS, simple, easy to use, robust, optimised for Arduino IDE. Full access to FreeRTOS capabilities, within classic Arduino environment.

This 'Arduino Fast Power-MOSFET Driver Cookbook' demonstrates three inexpensive options to drive large Power MOSFET's fast.

Most of USBasps are not able to program at 3.3V. Some say they can switch between 5V and 3.3V, but not signal pins, e.g. MOSI.

I want to make a CD spot welder for battery packs or other stuff that cannot be soldered.

FreeRTOS, simple, easy, robust, and optimised for Arduino IDE. Using FreeRTOS Semaphores to share and protect physical resources.

Back when I first started working with micro controllers, the most annoying thing was when a tutorial I'd spent hours following didn't work.

Basic and useful 4x4 T9 keypad, to text message.

I really want to make a Raspberry Pi laptop but just can't find the right size trackpad so in this project we will be salvaging an old one.

Connecting Arduino with accelerometer ADXL345 to Box2D with Qt framework.

Hack an old controller and use it as a combination of a keyboard and a mouse.

Use FreeRTOS (simple, easy, robust, & optimised for the Arduino IDE) to reduce the power required for battery or low power applications.
