LCD Mouse Hack

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

PIC Based Scope

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

80 Watt HF PA

Nice job rebuilding the guts of the transmitter. Why buy when you can rebuild. “This PA is a homemade copy of the famous Zetagi B150, I got a box and PL sockets from an old dead B-150. The PCB was so tired and burned so I had to construct it using no PCB at all.. At 4 Watt input I have 60 Watt out, 6 W in gives 80 W

LED Floor Tiles

Here is a great bathroom idea! Standard LEDs have a life of 100,000 hours so these should have no problem lasting till the next renovation. “Ceramic tile installations are meant to last a long time- We hope that LED’s live as long as their reputation or this bathroom is going to look pretty silly in a couple of years. The idea of marking steps and edges with LED’s is interesting;

Red LED Desk Lamp

If you have a few Red LEDs looking for a purpose, this desk lamp looks like a great project. Might be able to do it with a little less regulation but taking the cautious road never hurts. “Need a red lamp to provide soft red illumination around the telescope? Described here is an easy way to do this. Take a commonly available desklamp and convert it to LED’s. This is

4 Blade Micro Helicopter

  This RC Helicopter is so smooth, the design is also quite unique. “The Proxflyer Mosquito Twin-tail has 4 ch. control and is operated just as a normal helicopter, yaw, pitch and roll and it can fly sideways due to the two tail propellers. It is still absolutely stable and easy to fly. The Proxflyer Mosquito Twin-tail is a prototype and it is not for sale.”
