  • How to make a super-bright LED light panel (for video work etc)

    Hi! Great detailed video! Ive been working on building one with minot modifications and it has been fun along the way. I have 2 questions: 1. I split you board into 2 separate boards yet with exactly the same circuitry etc. When i connected the fan directly, without the resistors, it worked. However, when i soldered the resistors (6.8k) in series. The whole circuit stopped working. (Fan is 5v, im using a direct 12v power jack). I also noticed that once fan is running, the most the lights go up to is about 9v. 2. Even though I controlled the output voltage to a max 12v in the regulator, i noticed that if I increase the potentiometer to its max (fan still running without resistors), the circuit shuts down and turns back on and off in a pattern. The lights flash in a pattern. Would you kno...see more »Hi! Great detailed video! Ive been working on building one with minot modifications and it has been fun along the way. I have 2 questions: 1.
