Over the years there have been some electronic projects developed for the TI-99/4A. Some of these projects are massive in scale, like the TIPI, so beyond the capabilities of most here. Then there have been some simple projects, like Vorticon's model rocket launcher for the TI.
I'd like this thread to become a combination repository for projects, and a place to hookup, discuss and even make some electronic projects that can interface with the TI in "ONE WAY OR ANOTHER". And in the hope of more active participation, I'm asking the electronics engineers here to "please dumb it down a little" so others not at your level, or just starting out can feel free to get their hands dirty, learn and build along with us.
So, to hopefully get the ball started, does anyone have an idea for a low to moderately priced project?
