Tune-O-Sapien

If the Robosapien wasn’t cool enough stock, you can kick it up a notch by performing this music mod by Marcus. “In an attempt to get my V2 to open up a can of whoop ass on V2 Media, I decided to start with an important aspect, Music. Adding the ability to play music and sound through V2 allows you to plug in an Mp3 player, Ipod, Pocket Pc or

Bullet Counter for Marui G36C Airsoft Gun

This is a cool mod that adds a bullet counter to an Airsoft rifle. “The new circuit was built with the hopes that since the CMOS IC has much lower voltage requirement, it can still operate when the rifle is firing, but I was wrong. 🙁 Though my second alternative is to use external batteries, and power consumption is an important factor in this case. As far as power goes,

Wind Gauge

This PIC microcontroller based wind gauge interfaces with USB. It is still a work in progress but looks to be almost complete. “There are various methods of measuring the speed of a wind. With this equipment, a hemispherical window cup is rotated and the method of measuring wind velocity at that number of rotations is used. The measured number of rotations is sent to a personal computer with a USB

External Winamp Control

This is a simple way to add some functionality to Winamp. “Nowadays, winamp have full support to keyboard shortcuts. But some time, when winamp didn’t have this feature, I was thinking in some way to make a easy way to change music by simply pressing one button, it would make things faster and would help me to change music during games. So I decided to make a external control painel,

1.3GHz Frequency counter

This is a home made Frequency Scanner that is based on a Microchip microcontroller. “The brain of the counter is a PIC16F84, it does all the display scan, ranges calculation and main counter. More info about this counter can be found in the Danish HAM mag called OZ”

DIY LM3886  Power Amplifier

There are fill schematics and board layout for this powerful DIY amplifier that is based on the LM3886 chip. Looks like it is built like a tank. “This amp is based on the PA100 parallel amplifier detailed in National Semiconductor’s application note – AN1192. This amp uses two LM3886 per channel, in parallel circuit. This amp can deliver about 50W into a 8-ohm speaker and 100W into a 4-ohm speaker.
