How many of you have gotten instability from hdmi on the Raspberry Pi?! Especially with a HDMI to VGA adapters not powered.
Well… we'll hand over to you the solution!
Some time ago we have published a fix for usb power, it was a solution for all devices that you would like to connect to RaspberryPi.
Now, we extend the past project and we can add the fix that we're talking about.
The components that we have to solder in the schematic are minimals and ordinary.
– 2PCS 5.6 ohm 1/4W resistors
– 1PCS 10 ohm 1/4W resistor
– 1PCS LM31
All resistors are connected in parallel from pin ADJ to pin OUT of LM317. If you want more or less current you can add or remove the value that you want in relation with the formula:Iout = 1.2 / Rc
