Hi,
I'm building a PCB drill with a set of LED's, to point on the item being drilled. Apart from the drill side-of-things, could someone advise me accordingly with regards to my proposed circuit below.
I apologise in advance for R3 'i couldn't find the correct part in Eagle', but it is, a 1K Pot, using 1 input, and then the output from the slider. The LED's '8 of them', are 'i think', 2.8volts 20ma.
What i'm trying to accomplish is a variable 'dimmer', for the LED's, but to also have a feedback to keep the required current.
Any input is welcome.
Regards.
Dizwold.
