In this experiment I replicated Shinichi Seike’s example of a mixed (PNPx2+1NPN) transistorized coil which he used to demonstrate the “Time Reflection of an Electromagnetic Wave”.
What strikes me as interesting about this coil is that, when viewed as a whole, this coil operates much like one would imagine a transistorized Mobius coil would.
3x 1000ohm 1/4w (998 ohm)
3x 500ohm 1/4w (495 ohm obtained by soldering together 3 resistors)
1x SC2120 NPN
2x 2SA950 PNP
30cm copper coil 1.5mm diameter, from satellite cabling.
Plexiglass platform for mounting.
Note that at the time of assembly, the 2SB175 was no longer readily available and so I selected the replacement transistor 2SA950.
Seike states that transistors of 2SA, 2SB and 2SC are required to reproduce the correct results. This is something I need to investigate further and cane be done by comparing the differences between Seike’s recommended transistor types and similar common transistors like 2n2222 & 2n2904.
This design is similar to the endless amplifier and is based on the simpler 3 phase design. Seike recommends building a 9 phase version of this oscillator, something I will be doing at a later stage.
To explain how this circuit operates in layman’s terms(how I understand it), is that two of the transistors, the PNP’s, pull current and while the one NPN is pushing the current back into the circuit again.
The circuit oscillates at around 400Khz.
Interestingly enough, the lower the voltage the higher the frequency climbs.
Initially the circuit mimics Seike’s test results of an ever decreasing frequency over time. Then its stops and stabilizes after which it slowly increases in frequency as the voltage begins to drop in the battery.
After monitoring the circuit for 3 days I noticed during the day light hours the circuit oscillates at a significantly higher frequency while during the night a noticeably lower frequency. This pattern was common through the 36 hours of letting the circuit run.
Input current at 12Volts: +- 30 milliamps.
Single wave form.
Multiple wave forms I.
Multiple wave forms II.
Waveform continued; Anomaly:
Notice the wave pattern produced by the oscillating circuit. This waveform has the same frequency, but its amplitude is gradually being modulated and forming another waveform superimposed
Here you can see it more clearly.
And again here, it’s even more apparent.
If you can share some information on why this could be happening, feel free to leave a comment.
Further investigation is necessary and will be done after the 9 phase mixed transistorized coil is built and tested.
