“We purchased an RC car, removed everything except the body and the motors, and replaced all of the circuitry with our own microcontroller-controlled network. We also built our own controller using just the existing case. For the transmission of control signals, we used a 418 MHz transmitter/receiver pair purchased from Abacom Technologies.”

“How to control your camera shutter release from your Ipod (r) or other MP3 player. An ‘intervalometer’ is a device that remotely triggers the shutter in a DSLR camera at pre-defined intervals. This can be a very useful device for shooting time-lapse video or simply a sequence of shots at regular intervals without operator intervention.”

“The servo switcher is designed as an aid for anyone who wishes to convert a remote control vehicle into an autonomous vehicle, in this case the project is a sailing boat, however the design can be easily expanded to work with cars, planes or helicopters.”

“ In this article, we will use a PIC 18LF4520 and an Arduino UNO to build a transmitter and receiver using some wireless modules. The PIC will output serial commands as a transmitter that tell the Arduino system to pause an LCD screen from updating a counter value. This project is intentionally designed to be simple because there are many simple ideas at play and it’s important for you to understand each one.”

“A while back, a few friends and me were joking about what people would do when all the sudden, instead of going back and forth, the cat’s arm would start moving sideways. The idea had been stuck in my head ever since then, and now, we’re about to find out. So, let’s hack a beckoning cat.”

“At the end of the last cold season, I decided I’d make another pair of liners, this time with only one 5′ strand of nichrome wire…A short test on the bike proved I now had heated liners that allowed me to use more than the lowest setting on the controller. I guess these are Glove Liners 2.1.”

“Digital timer switches are used to control the operation of electrical devices based on a programmed schedule. This project describes a programmable digital timer based on a PIC16F628A microcontroller that can be programmed to schedule the on and off operation of an electrical appliance. The appliance is controlled through a relay switch.”

“Our project controls a propeller-driven toy blimp; it keeps the blimp moving in a straight line if its path is clear, and otherwise navigates it around obstacles in its path. To accomplish the former task, our circuit uses a gyroscope to detect horizontal rotation and compensates for it by adjusting the propeller speed. Obstacle detection is performed using a digital infrared proximity sensor.”

“The E-bike computer. It gives me different information about the bicycle like: battery voltage, external temperature, temperature of the battery, speed and distance traveled. There is also a throttle and state of charge indicator. This is how I accelerate the bicycle giving the input to the motor to move forward.”

“The purpose of this project was to create a simple, portable device that would periodically read sensors and then store the sensor data so it could be retrieved later.The result is the HexiLogger, ‘hexi’ because it can support up to six different sensor inputs and ‘logger’ because it will store the input data on a removable SD memory card.”
