I have a DIY project, with the aim of building an (LED-based) stage/theatre light from scratch.
One of the challenges I've hit with this is getting DMX control to dim the LED. I spent some time looking for an 'out of the box' solution, but to no avail. This lead to researching some DIY options, and I've thought of three potential solutions. I'm unsure as to the feasibility of each, so your feedback would be much appreciated!
1: Using an LED Strip DMX Controller and then boosting the (12V max) PWM output signal to 32V max. Unsure if there is equipment to boost the PWM signal correctly to match the 50W (32V) LED dimmer curve.
2: Taking a 12V power source, stepping it up to 32V via a variable boost converter. Then can dim the LED via a potentiometer connected to the 'voltage adjuster' on the boost converter. Figure out a method to control the 'voltage adjuster' / potentiometer via DMX. Unsure as to this part of it.
3: Going full breadboard, building a controller from scratch. Something from the following documents. While I'm sure I could replicate the PCB designs shown, I would have absolutely no knowledge of what each component does.
If anyone has any suggestions as to which approach would be best (or a seperate approach), or any improvements that would be much appreciated!!!
