In the last episode I described plausible developmental ways of my universe. Because of limited budget I did not decide yet to change bridge or coils. It's worth to do it someday, but it won't be any brand name construction. The best choice for bridge will be still something like floyd-rose, because limiting to one-sided tremolo would be a loss when guitar body construction enables adaptation of two-sided. However I will search for some cheaper coils solutions, maybe there are coils magnetically shielded yet. I could use an active humbucker also.
Until now I have finished some toughest workings, I mean instalation of stars, power sources, regulators and a switch. During carving the traces for wires I didn't avoid some scratches on the neck and, unfortunately, once I drilled troughout it. Scratches
are not visible too much, but maybe some day I would like to draw something on neck and the hole is actually on the 12th fret, so it also might be an advantage, because it's easier to orientate about position of hand during playing. If it will be helpful I may match some other frets this way.
I have installed 12 blue stars on neck and 6 orange on the guitar body. Brightness of its light can be adjusted with two potentiometers (500 Ohm and 1 kOhm). Junctions of electrodes appeared not to be identical for each of them, so it gives an interesting effect of shining with different intensity. Orange diodes shine dependently on actual position of 5-positional switch and show which coils are actually turn on. There was a
problem with isolation between coils circuit (alternating voltage) and diodes circuit (direct voltage). It was necessary to do it, not to carry direct signal to a signal from the guitar (audible hum in loudspeakers guaranteed). Transformer separation was out of question - too much of thinking and not to much space. Configuration of photodiodes would have to be made very precisely, so mechanical separation was the best solution. There was needed a curved wire, head of a pin and unmounted ethernet socket.
Blue and orange diodes are powered by separate circuits. The switch (yes, I know it's rose, but only rose were tripple and had the best shape) enables turning on two circuits separately and gives a possibility of application other solutions. The whole thing is now powered by two 1,5V batteries places in a casket, which I got from an old clock-toy in shape of a duck. The casket with socket for electrodes endings fitted perfectly in space between springs retracting the bridge.
Meanwhile there is such an astronomical phenomenon like blueshift, which consists on a fact
that spectrum lines of an electromagnetical radiation, that come from some stars or galaxies, are shifted to decrese in wavelength (increse in frequency), which in visible lights causes a blueshift exactly. It's because of Doppler effect connected with movement of a source towards the observer. This kinds of spectra can be seen for some stars placed quite near to the Earth in our Galaxy. Analogous phenomenon to blueshift is redshift, which is connected with objects that are moving away from the observer.
My stars depend on themselves, because they use the same power source, so intensity of their shining depends on regulation of resistance and actual position of 5-positional switch (in two positions shine 4 diodes and in other three - two diodes shine). It turned out that blue diodes shine the most when humbucker is turned on.
It's possible to expand the structure by adaptation a system of powering the diodes from outside using transformer or impulse adapter. I will also think about the instalation of a solar panel instead of a hatch at the bottom side of the guitar body, but it's still hard to find something cheap, which would be easy to adapt to efficiency of accumulators (in question of speed of charging and occupied space) and diodes requirements. But now my universe works quite well, especially with connection with usual kitchen clock, which I use as a metronome.
