LM30 becouse LightMer, 30 is number of my project.
Cover - sheet metal AL 1,5mm, that I have to cut, drill, it's writhen and finally black painted. Letters I made using PENTEL STEEL POINT PEN with a little help of template couse my hands shake to strong.
Plates were designed in Eagle and made photo methode.
Controller was made to steering lights at house, small party's or as a backup at big disco's. Oustput power is limit only by efficiency of house wiring - max 16A what gives 4A per channel, so about 800W per each colour)
Steering the bulbs - typical application with optotriac and triac as a executive arrangement. Steering of comparator (uA741) from "saw" and dimmer's voltage - get from http://www.elektroda.pl/
Bulbs ( or any other kind of light) can be turn on or turn down by two relays - what raise abilities of the controller ( you can connect two circuits of lights and steering them independently [turn on / turn off].
Power supply adaptor - typical 5V for digital part, +/-12 for comparators, "iluminofonic" and"saw".
LM30 have got two independent input blocks:
1) Iluminofonic - signal ( line input or jack or microphone ) thanks to active filters ( uA741), cut in to four zones: low - red, middle - green, high- blue, presenz - yellow.
Possibility of adjust sensitivity input signal for each zone.
LED above each potentiometer with right colour.
2) Digital - steering by 555 generator, processor (ATMEL 89C2051) with changing light sequence. Sequence choose by pressing button, frequently of blinking by potentiometer. Again LED as a controls.
Dimmer in a potentiometer that can adjust voltage.
