On Oct 31st our small town of Ryderwood has a Halloween party (this is a 55+ city) and they have prizes for best costume.
My idea for this year is a Cyborg. Using an old cpath mask w/ hose, put multi colored LEDs in hose and blue leds in mask. All controlled by a 4017 decade counter. Want to use a pic but time is not on my side. That's next year w/ LED matrix blinking eyes.
My plan is to use 8 opticoupliers driving 8 triacs. Yes I know I should use led driver chip and constant current chips as well but looking at putting the LEDs in series w/ about 8 per string (lots of load to drive. need to calculate current etc) looking at using several AAA or even D batteries. Thinking 12 volts might do it but ??
reason for using the opticouplier / triac combos is I found some left over SSR boards from my computer light display.
Now to locate the smd LEDs, small ribbon cable etc.
Any additional ideas are welcomed.
