The project converts a stovetop pressure cooker/canner into a fully automated pressure processing system with the addition of a few inexpensive components. It can accurately monitors and controls the pressuring process.Using a Renesas M16C microcontroller, the system can control the entire process using an ordinary off-the-shelf pressure cooker/canner and portable electric coil burner. Once the process has been setup, this controller allows you to walk away from the burner and return when the jars have been sealed. The entire canning process has been simplified with the addition of this controller. ...

The project aim is to build a quadrotor helicopter flies with 4 spinning propellers on a + shaped frame. It uses four brushless motors. Each motor will be controlled by an ESC (Electronic Speed Controller). The ESCs will be controlled by the microcontroller. This microcontroller will also take input from a RC radio receiver, so you can control the helicopter from the ground using a RC radio transmitter. A lithium polymer battery is used to power the project.When one rotor spins faster than the rotor on the opposing side, the ...

The AeroQuad project is an open-source hardware and software project to build a quadcopters or quadrocopters, remote controlled four-rotor helicopters. The hardware consists of an Arduino microcontroller (Mega-2560 or Uno) as the flight controller board and an AeroQuad shield with various sensors like accelerometer and gyroscope.The project software is written in C and uploaded to the microcontroller via the Arduino IDE. At this time, it supports Rate (Acrobatic) Mode that uses only the gyroscope for flight assistance, and Attitude (Stable) Mode that use both the gyroscope and accelerometer for auto-leveled ...

The infinity bug is connected across the phone-line of a distant phone in parallel mode. It uses surface-mount resistors, capacitors, transistors and diodes. It gets operating current from the phone line (leech device), no external power supply is required.To use the Bug, the distant phone is rung. After having a conversation with the person at the other end, they will replace the receiver. At this point you whistle into the receiver and the Infinity Bug will pick up the line. The high-gain amplifier in the Infinity Bug will pick up ...
