B+K Precision’s model 2120B is a dual trace oscilloscope that offers high performance. This unit is great for the hobbyist or student that really needs an oscilloscope. It has all the standard features of an analog scope and has worked very well for simple tasks. However, if you need any complex measurements or functions, you’ll have to pay up for a digital scope. B+K Precision products are always a great value. Read more 20Mhz Dual Trace Oscilloscope

Open GPS Tracker is a small device which plugs into a $20 prepaid mobile phone to make a GPS tracker. The project use microcontroller AVR ATTINY84 as main processor. The Tracker responds to text message commands, detects motion, and sends you its exact position, ready for Google Maps or your mapping software. Mike release the Tracker firmware under open source license and user-customizable. In addition to being a GPS tracker, the firmware is easily modified to monitor and control anything from a weather station to a vending machine via text messaging Read more AVR Open GPS Tracker

The TiltStick is a small acceleration sensing device in form of a USB stick. The main part of this project is microcontroller AVR ATmega 8. To measure acceleration (caused by motion and tilt), the project using a two axis acceleration sensor. The device is emulating a USB joystick and can thus be used in conjunction with any USB equipped host (e.g. a standard PC or the Nokia N8XX family) without any special drivers.

This simple Digital Thermometer project use NTCs as the temperature sensor and microcontroller AVR ATmega 8 as main processor. This thermometer can be used as a standalone thermometer with LCD display or it can be read out with a PC running Linux, Windows, MacOSX or Solaris. For reading the temperatures no special drivers are needed.

In the past to interfacing with microcontroller many people always used rs232 communication with the UART that is included in the microcontroller. It requires an additional MAX232 chip, 4 extra capacitors and an external crystal oscillator for the microcontroller. Read more AVR Simple Digital Thermometer

This project shows you how to build Remote Control Car system that can identify a parking space and parallel park by itself. The project use IR Sensor and Micro H-Bridge (L298HN) to control the motor. As main processor, the project use microcontroller AVR ATMEGA 644. Read more AVR Autonomous Parallel Parking Car

The ultrasonic haptic vision system is AVR project that enables a person to navigate hallways and around large objects without sight, through the use of an ultrasonic rangefinder that haptically interfaces with the user via tiny vibrating motors mounted on the user’s head. The idea behind this project was to construct a sixth sensory system that interacts with the body in an intuitive and user friendly fashion and enables the user to navigate without vision. With advance development, this project will be good aid for blind people in the future. Read more AVR Ultrasonic Haptic Vision System

If you tired with All TVs everywhere or you want a break from advertisements? TV-B-Gone is what you need. TV-B-Gone is a universal TV remote control which only has one button to switch a TV on or off. As you can see the device is so small that it easily fits in your pocket, so you can carry it wherever you go: airports, bars, restaurants, laundromats, etc. The main part of this project is Microcontroller AT TINY 85. This project originally designed by Mitch Altman. It’s nice project if you want turn off all those LCD TVs everywhere? But use it wisely it public area Read more One Button Universal TV Remote Control
