I was after a small OSD for my Blackout Mini H Quad build and thought I’d try out the Hobby King Super Simple OSD. The only issue is that I was using the recommended and ubiquitous PZ0420 which requires 12V power. Adding extra cabling and regulators would increase the complexity of an already tight build, so I decided to merge them together.
I collected the required materials. A 7 x 1 2.54mm header, U3V12F12 step-up regulator, some silicon wire fly leads, the Hobby King OSD, some heat-shrink and double sided tape.
I wanted to be able to plug in all the required connections, so I’m replacing the existing headers with my own. Firstly let’s strip off the heat-shrink and the headers from the video side of the OSD.
The 5V input and 12V output pins need to be added with some flywires to the header. I bent the pins for the video and ground connections down, the power connections up and removed the centre pin as it isn’t used.
Prepared the regulators by soldering the fly wires.
Test fitted the the regulator to determine the length of wire required and clipped short.
Shortened the pins on the header for the power input and output and soldered the fly wires to the pins.
Soldered the header to the OSD and the ground wire.
Added double sided tape to the bottom of the regulator and stuck it onto the OSD.
Covered with heatshrink.
