Sean Harrison has built a very cool hard drive project. Similar to the Hard Drive Oscilloscope but uses two hard drive voice coils instead of just one. This allows the unit to draw an X/Y image without needing to control one axis by hand. “Right, well I had been looking around the net and found the Hard Drive Laser Oscilloscope over at Hacked Gadgets and thought about trying to
This is a good use of a sample PIC chip and a handful of extra components. Check out the site for a complete schematic and construction details. “On this page i will explain how i created my own colour changing lamp with red, green and blue leds that fades between all colours of the rainbow. It really comes out well at night when other light are dimmed. In daylight
Not much to say about this one. For this mod a picture is truly worth a thousand words! “For some reason I had a thought on trying to combine a graphical LCD with a computer mouse. Perhaps this had something to do with my review of Logitech’s G15 Gaming keyboard six months back. Like in my MouseFan mod that I did in 2001, I decided to joke around by addind
Here is simple PIC microcontroller based scope. Looks like the software has quite robust features. “SISAM – SImple SAMpler – is a simple PIC-based hardware for precision dual channel data acquiring with moderate resolution (up to 500 ksps in continous mode and up to 5 Msps for very short sequence). It uses USART and SSP for sampling signals and software routines for RS232 communication. USART is configured for synchronous master
