# Osci Video PCB

Based on the [XYZ converter by MrSlehofer](https://www.youtube.com/watch?v=UZapLL3Qa-I).

This PCB design is ready to be ordered and assembled from [JLCPCB](https://jlcpcb.com/)!

Just upload the files in the `production_files` folder to their webshop.
All settings should be fine, just some manual translation of the RCA connectors may be needed in one of the last steps.

Warning: in the board revision `V1` the PNP transistors U2 and U3 were placed the wrong way round.
This has been fixed.

The `V1` revision did not work at all.
The R1 resistor had to be reduced to 6k8, the R10 resistor to around 24k, for my test setup to show a proper picture.

Also I'm referencing the Z output to GND, instead of to +12V like in the original PCB design.
Otherwise with scopes like mine, where the XY and Z inputs all have common grounds, would cause a short circuit of the power supply.
Sadly this inverts the brightness of the video drawn on the scope.
