Successful TPU-ECD replication !

Jason:

Thank you for the heads-up on finding these fairly inexpensive battery operated function generators specifically to drive the three phase oscillators. I sure am looking forward to your good work on verification of the usefulness of these function generators. Only thing is, like you say it's only good for 500k hz? Maybe a problem if we needed higher harmonics.

Please let us know your progress. If they work well, I will be getting 3 myself too!

Hi Chris,

I already own three of these function generators and used one of them for the original demonstrations that I did (I blew the IC in the other two from some earlier, unrelated, experiments).

They will drive the MOSFET drivers up to 1MHz with no problem at all. And the other good thing is that they are controlled by a single monolithic function generator IC so if something ever goes wrong and you blow one up, it's very easy to pop the chip out of the IC socket and get another one for it (they run about $8 for replacement chips). This is definitely cheaper than replacing a $200+ generator if you spike it out. I definitely recommend these to everyone as an easy alternative to the fussy 555 chips.

God Bless,
Jason O

Thanks again. can you vary the duty cycle on these?

Hello all,

sorry I was a few days off line.

I saw the last video. A few comments:

1. there are 2 frequencies used and everything was OK. Then the 3. frequency added and nothing was OK!!!

When you use 3 frequencies, when you see that the 3rd frequency "disturbs" the other 2 frequencies then you MUST surch for better frequencies. The first 2 frequencies are NOT GOOD. You have to find a better frequency mix for your first 2 frequencies and then add the 3rd.

When all 3 frequencies are OK then you can swith off 1 frequency and the bulb shines NOT so bright as with all 3 of them. Then swith off 2 frequencies and the bulb is maybe only glowing.

In this case you know that all your 3 frequencies adds a littl power to the bulb. This is then the frequency mix you need.

This is then what I call a harmonic work off all 3 frequencies.

ps .. i cant download the vid from the link or other vid downloaders .. it keeps erroring .. may be a prob on my end.

No devilzangel, your correct, theres an issue with google videos, I just tried another d/ler as well.
That d/l link used to work, somethings changed.:- http://javimoya.com/blog/youtube_en.php

I just sent google video an email, telling them of the problem with there videos, hopefully will get an answer, will let you guys know.

@Otto, appreciate your guidance, thank you.
