I’ve been in the field, testing these dongles, make sure they perform as intended. This mainly involves going thrifting and plugging these things into TVs and monitors while curious people stop to look at me like I’m up to something . It combines two things that I like, looking for electronics and playing with electronics.
It turns out that the VGA dongle is a little too big to fit a small percentage of the monitors. The TV monitor dongle needs to have its RCA jacks relocated for easier connection.
While working on this, I decided to create a similar board for arcade monitor testing, which may come in handy when testing arcade monitors in the field. Hardware and software is similar across the 3 devices.
More info on the project can be found here. The project page will have more information on these, and will be updated when these become available.
