Joe Grand has finished work on his Laser Range Finder (LRF) project. This project, which has been in development in cooperation with Parallax Inc., is now in final beta testing. Check out Joe’s development diary for all the exhaustive details and links to development videos.

Joe reports that after final tweaking is completed, he expects the module should be going into production sometime in July and would be ready for sale through Parallax a few months after that.

Car battery and charging system monitor

This project is about making a simple electronic voltage monitor system for car’s battery and its charging system. It plugs into the car’s cigarette lighter receptacle and displays the instantaneous output voltage across the battery terminals on a 4-digit seven segment LED display. This helps you to get early warnings for possible battery and its charging system problems.

Always thought of making your own PC based signal generator?

Advantages of PC based signal generator: -

1. Low cost, no need to spend lot of money (costs about Indian Rs.30 = US$0.67 = costs almost nothing).
2. Can generate complex signals, like Sin(f1) + Sin(f2). Any function that you can write and understand its limits can be generated from PC.
3. Easier to operate, because, most people who finds signal generator useful are well versed in computer software + hardware.
4. If you use a output buffer amplifier, the chances of damaging your PC sound card is very small. In other words, it is safe.
5. Portable i.e only laptop is needed. Do not need to carry one more signal generator.
6. Use PC sound card, unless you listen to lot of music while working on electronics stuffs.

The 8 pins PIC12F683 microcontroller is one of the smallest members of the Microchip 8-bit microcontroller families but equipped with powerful peripherals such as ADC and PWM capabilities. This make this tiny microcontroller is suitable for controlling the DC motor speed. In order to demonstrate the PIC12F683 capabilities and to make this tutorial more attractive, I decided to use the PIC12F683 microcontroller to generate simple and yet fascinating laser light show from a cheap keychain laser pointer.
