Successful TPU-ECD replication !

I'm eager to start winding once I see some confirmation of the initial results with RMS input current readings taken along the lines already suggested using filters and a 12V battery as the power source.

Hi Rob,

I see your point. There is as always at least a nice way around. For the synchronous operation just use DDS SW to preset correctly a programmable hardware synchronous counter. You could provide actually for the preset of 3 synchronous counter on the board. So clocking the 3 counters with the same master clock trough an enable signal we get just what we want.

What do you think about (of course there are many similar options...).

Marco, quite a nice Avator you have drawn !
Looks very nice !

The frequencies are all asynchronous, I cannot see how you can sync them.
Maybe fine tuning the phase perhaps.

If you are using AD9833 (10pin) DDS then you can synchronize multiple chips with this procedure:
1. stop the common clock to all DDS
2. program individual DDS to obtain required waveform, phase and frequency
3. send soft reset command to all DDS
4. enable the clock

Other DDS chips (ie. 18pin AD9834) have Reset pin that can be used for synchronization.

Otto and all of us on this Forum wants this to be in the public domain and formally publishing this document and 'records' of these on-line interactions together constitute "prior art" per the date of public records being kept. There is no need to even go any further.

Now, UEC or whichever SM assigned his invention to (if there was such a patent) had one year from the first public disclosure (1997?) to submit the invention to the patent office, after the one year period, his own invention constitutes prior art to himself and becomes public domain.

Also, even today, unless SM or UEC publicly disclosed their 'invention', we will never know if their "claims" are being thread upon by Otto's contraption of double mobius arrangements, etc. A patent is only as good as what is in the claims.

Anyway, welcome to the 'believers- club'! Membership is free. The only other requirement is to free your mind of previously conceived or previously taught orthodox ideas of how things can and must be done!

Peace
