More stuff….

While I haven’t made any recent updates for a while, there is actually a lot of stuff going on. I put aside some of the long term projects (probably a bad idea) in favor of some quickies.

I spent the last few weeks working on RGB modding Sony Trinitron TVs. I ran into some issues with that but in the end was able to overcome them. As a result I made a Sony modchip board that can be used to enable an unused RGB input on Sony YC Junge chips inside of their TVs. I’ll put up a page with more details soon, but in the meantime here’s a link to the Youtube videos I made on the subject.

While working on the videos I decided to make a small dongle boards for testing TVs and monitors. These dongles will be battery powered and will output various signals to allow you to quickly test the equipment. Mainly this is for people that go thrifting and need to make sure the gear is working as expected. The vga dongle will output a 15khz test signal to help you find those elusive 15khz capable lcd panels.

In addition to that I made a simple yet effective in system debugging board for value line msp430 microcontrollers. The idea here is to use your existing msp launchpad and connect it with an extension ribbon cable to your system. The board provides switches for the TEST, RESET and VCC pins to quickly go from programming to in system debugging.

This board design is available for free, but if you want to get a fully assembled kit I will make it available that way as well (coming soon).

Finally I’ve been working on more JAMMA adapters. The current batch consists of adapters for Exidy, Nintendo Playchoice 10, standard 8-liner pcbs with 72pin + 20pin edge connectors, Space Invades with virtual color overlay, and improved designs for the existing Nintendo adapters.
