High frequency PWM video light controller and channel mixer
I finally got around to designing a circuit to control my smaller bi-color 60W 3200k/5500k LED panels. I used an arduino UNO and some high power NPN transistors to allow one of the two knobs to vary the intensity of the panel and the other for controlling the color temerature. The photo is of the test circuit. I'll be building it into the final panel in a day or two and it should be ready for my commercial photography client next tuesday in Charlotte, NC! #diycharlottencvid
Testing my new custom built LED video lights -Raw footage set to Daylight WB
This is an improvised test of the new LED lights. Pretty much just gave him a cookbook and asked him to read me an excerpt. The main 140W panel is of my own design and the two rear lights are highly moddified 100W Arri knock offs. The main panel can hold it's own against a $4500 Kinoflo Celebrity LED panel and even beat it for power slightly. I am pretty happy with the results, very little color shift and perfect for some commercial video and photography projects I have com
