This Line Level Color Organwas one of my earlycreations. I brought variouscircuits together that othersdesigned. I updated itrecently and modernized it abit. The original versionflashed neon bulbs insteadof LEDs on the front panel.The updated version flashesboth, if you wish. The unitresponds to 3 frequencybands: high, medium, andlow.

At one time, this unit flashed3 stings of lights on ourChristmas tree. It was a bitmuch.

The metal VU meter scalewas replaced with a paperone and illuminated from theback.

When I was younger, theliving room was equippedwith large speakers and analmost floor to ceiling stereoequipment cabinet oncastors. I had lightseverywhere!

It’s all gone now and I’vesettled down to listening tomusic from the computersystem. The house doesn’trock anymore!

These are Straw Hat LEDs.(The diode is close to thesurface.) This is the onlytype I use to illuminatemeters. They have a wideviewing angle which makesthem ideal. Round Top LEDsmake too much of a spot onthe meter.

Not much room leftover inthis box!

Notice the label under thePCB. It helps me find thebest position for the boardas well as how it relates toother parts.

When I find its final restingplace, I adhere it to thecabinet and use it as a drillguide. No guessing normeasuring with this method!
