This project use a PC for GUI display and AVR Based data converter board. The circuit is built with the ATmega8. The GUI programming with Visual Basic to receive data from ATMega8 vai RS232. The ATMega8 chip has the onchip 10-bit resolution A/D Converter. Temperature sensor are connected to the 6 channels ADC input. You can connect up to 8 sensors with the ATmega8 TQFP package. [more]
This DIY Parking Sonsor using Arduino, ultrasonic range finder and some of components
Mike writes :
The last time I was home visiting my parents I noticed bumper imprints caused by my mother suburban on the stairs leading up from the garage. Their garage it turns out is just barely long enough to fit their gigantic vehicles. So I decided it would be nice to have some visual cue for parking. Out came the arduino and a sonar range finder from Radio Shack.

The basic concept of the Keyglove is to generate input signals by touching unique combinations of conductive sensors together. These sensors are mounted on the fingers and palm of the glove in strategic places to allow for the greatest possible number of combinations.The glove also has an accelerometer on the back, which will be used (where applicable) to control mouse movements.[more]
This latching continuity tester detects intermittent (and steady state) opens and shorts. The tester will detect and latch on an intermittent condition with a duration of less than a millisecond. In addition, it provides both visual and (defeatable) audio indicators, uses only one inexpensive and easy-to-find IC, and can be built very cheap if you have a well-stocked junk box. [more]
This is a small size GPS-logger module. You could use it for different purposes. It can be carried elsewhere or mounting on a model airplane, track your journey in the car etc. It has a built in Lipo battery. This module can record your track for viewing on Mapping application such as Google Earth by retrieve the data via a small Visual Basic program installed on the computer. This project using PIC16F648 to read the serial protocol of the GPS then store on EEPROM.[more]
