Naturetm documents the details on how to produce composite video using the MSP430 found on the TI Launchpad. He used two resistors and the source code is able to produce monochrome NTSC video in 192×40 resolution. [via]

This project is a small video game console build of a sandwiches a lithium button cell between the psp joystick and the pcb. It uses a ARM Cortex M0 32 bit cpu and is able to produce 3D graphics and sound. Output resolution is 320×240 composite or s-video and is able to produce 256 colors with standard palette. Sound is 8 bit 15khz stereo audio. Check construction details on the link below.

Hackvision is a simple, retro gaming platform based on Arduino technology that you can assemble and connect to your TV. You can write you own games and make your own controllers! The best of all is that is open source and you can find schematics, boards and source code on the site below.

A2601 is an FPGA-based clone of the legendary ATARI 2600 video console, developed completely by retromaster.wordpress.com, including VHDL code and a custom PCB. Retromaster recreated 6502 CPU in FPGA along with TV interface which enables NTSC TV and audio playback. Check project details on the link below.

This project is designed to show how to build time-dependant applications on PICs in C and to deal with restricted hardware. It will also help you to have a start point, if you need a simple way to add text to a PAL composite video signal in real time. With only an 8 pins PIC and a few cheap components, you can superimpose constant or dynamic text to a composite video PAL signal.

Gary Dion’s AVR based video overlay titler, source and schematics included.The WhereAVR is a small, lightweight, low-power, and low-cost APRS tracker with a full compliment of analog and digital I/O, as well as the ability to decode ax.25 packets. This allows for the reception of remote commands without the need for a “real” TNC. It is designed to hook directly to the speaker and microphone jacks of a handheld radio. One caveat, however, is that it currently doesn’t have a spiffy configuration utility. [via]

Video switcher allows monitoring up to 4 security video cameras. Interesting thing is that device uses intelligent method of motion detection. PIC grabs low resolution (8×8) video frames and then calculates numeric sums of screen regions to detect motion by detecting image changes.

Of course it may seem that PIC microcontrollers are too slow for taking frame or even single video line at once. So it reads one sample per video line while line skewing has no practical difference. This way it collects all 64 data points. The Source File only implements the 4 cameras. You can connect any number from 1 to 4 and the software will sort out the detection and switching. Motion on any video input switches the output immediately to that source. [via]
