AV to HDMI converter adapter for 3DR Solo

If you use some camera that has only AV-output, you can use this kind of converter.

As you can see from pictures, this is not easy to build.

I found 15 cm flat cable, 25 cm miniHDMI - HDMI cable and AV2HDMI-converter from Aliexpress. I removed AV-plugs from converter, and soldered original Canon AV-cable directly to pcb. (This reduces weight)

Probably most difficult is to find proper connector to Solo accessory bay. Alternatively you can use some small and light power bank battery and u
