Tonight give great Success for US and A!!  Very nice!!   I like!    MACEDONIA TPU!!!

Okay in plain English , I got the Arduino microcontroller to talk to those tiny little LTC6904 oscillator chips.  It changed their frequency from about 1khz up to 8.3khz.   This was very headache-free from digital EE standpoint and I will be happy to answer all questions on how to replicate.  The cost of the displayed setup is about $40 in parts.


Here is a picture of the circuit... the Arduino is the green microcontroller board on the left and the LTC6904 is the tiny oscillator chip on the breadboard.


Here is the counter showing the output frequency of the LTC6904, which was 8.369khz after stabilizing. We were expecting 8.312khz.


And lastly, here is a screenshot of the microcontroller's code.   Notice it's SIX LINES...  This is why you should get an Arduino.


We can program these frequencies for just about anything.... resonance scanning, pulse charging, TPU research, whatever.  "Dial-A-Frequency".

Allright I'm going to post this for Jon. He also was working on things last night...  These are his latest results.

A single channel test is running now. It is just a logistical test to ensure that all the pieces are working together I don?t expect the results will reveal anything interesting. There are a few problems yet to work out.

The oscillator has three bands that are set with a jumper. The digital resistor has 5120 values of resistance between 2-3 ohms and 210K ohms. The test runs through one band testing each value for one second and samples the output value 6 times per value. The results are ploted on the screen and written to a csv file.

      Jon still needs to wind the control winding over everything.  Below is what I believe Spherics described as SM's build.  Problem I see is that the control winding is going to mess around with the timing on the kick swinding. Maybe not.

Thanks sparks

I have not built a TPU myself, but I'll forward your recommendations to Jon.

Okay, so here is some of Jon's latest results.  I have been playing with LEDs this weekend, but Jon has been doing real  TPU research!!!

I have started on an isolation circuit to separate the TPU from the microcontroller in case of damaging output spikes. It uses an LED, a photo cell, a .1uf capacitor and two variable resistors. The LED will not produce linear output and the photocell takes a bit of time to update but my primary concern is to protect the microcontroller. The circuit is installed in a small box to block out ambient light.

For such a simple component compared with the rest of the project it has been the most difficult to finish. Four hours later is still doesn?t work. The current TPU output is not enough to light the LED in the box but it does light an LED on its own. I may have to bypass the variable resistor.

This is the first draft of the 6ââ,¬Â³ TPU results with one channel. The data collected used an LED powered by the TPU and detected by a photo cell connected to a microcontroller ADC. The gain is too high so the data was cut off at the top in two places. The frequency is not labeled but the left hand site or lower resistance value is on the left.

There are 5120 frequencies tested each for one second and sampled 6 times each value. The inital results are for the LTC1799 higher frequency band.

This graph shows the results run again with the oscilator freqency band set on medium

Feynman:  I think this graph shows TPU voltage (Y-axis) vs oscillator resistor value (X-axis).  I *think* that lower frequencies are to the right and higher frequencies are to the left.
