I haven't touched the #Video Pendant project in a while, but I think it's really time to resurrect it now. CircuitPython has grown a lot in this time, and I also wrote a library that reads GIF files in Python, so there is much that can be improved on the software side.
On the hardware side, I'm going to continue where I left off. I will use the new configuration, with the screen on one end, and the battery holder worn on your back, under the shirt:
This allows the pendant itself to be much smaller, and the battery to be much larger. I will probably switch to a pair of regular alkaline AAA batteries, instead of rechargeable LiPO. They are safer and much easier to get. Also, I don't need to ship them with the device.
