For some reason I ended up designing a video adapter board today. This is not as high-tech as the UBE video adapter, but a stripped down "no frills" (aka cheap) simplified version. It will still do colour and mono, the selection is done by a simple jumper link. It has a audio out connector, It is a through-hole part and should be more sturdy than the SMT ones. This one has a metal "wrap" around the body which sold as to the board, so the sockets I plan to use are probably as substantial as they can be.

This adapter has the VGA connector higher up than other adapters. This was done as it should fit the MEGA ST better ( assuming the connectors are actually in use either side of the board) it may not be ideal in all circumstances,But at least for my use it would actually be better this way.

Progress :)

I have just noticed the back of the bracket where the switches, is actually set back a couple of millimetres, so I will have to fix that next...

3.5hours print time ... I took the bracket layer height down 2mm (was 6mm) and saved a lot of time...

Its now printing, but I've not printed anything this large yet, so probably will fail after not long anyway :P

I have the blue light filter thing on the phone so not sure what it was.

73% so far...

All the time seems to be going on the hexagons in the middle :roll: I might try the next print and remove them totally.. or just put 3 or 4 diagonal supports in the middle instead..
