Chinese Oscillator and MOS FET Driver, Hardware experiment

1) The 4,7nF capacitor goes to pin13 and not to pin8 as you have made it above.
2)The IC we want is the 74LS132 schmitt quad nand gates. Without the letter "D" at the end which i think is the smd type of the IC.
3) In your drawing you forgot two more gates so you need one more IC for them. In total you will need 3XIC's in a total of 10Xgates. Look the original circuit again above.
4) When you finish your board you need to attach 100nF ceramic capacitors straight on pins 7,14 of all your three IC's
5) I am afraid that you will need an oscilloscope to adjust and learn the behaviour of the board.

That is the associated video which will give you an idea of the layout.

The business of modifying/upgrading old ready-made items to new ones is one of the most thriving businesses around the world.

This is a good example of how a promissing thread got totally diverted in to the ground. Yes. The agents live amongst us.

Mr Plasterer  Perhaps Jed has a ware house full of old Low Power TTL devices 

At some stage Ruslan bless him  let the cat out of the bag in the Russian language
when he started selling his devices some where on this tread the young lady on this
thread posted a link to it not all that long ago but it's such a mess god knows where
it is now, but its still on here only find it and go through it all.

There is this posting some years ago that works as far as generating the timing
pulses is concerned. I knocked up the first 2 stages on a bread board the delay
and the pulse width section and fed it with a CD4047 oscillator and used a CD4093
at 15 volts and it worked well after a bit of experimentation but ran out of components
after that 

Regarding Color's 494 circuit I couldn't get the 494 to lock on the correct place  and
it kept trying to lock while having some kind of unstable  'twitch' where the data window
appeared to try a synchronous lock, It was just a wast of time. Any way such is life.

Yes too sloppy here
And a bit vague on what is being said


I think a new fresh separate topic at all forums will be good !


For teaching purposes ( educational tutorials on how to save our planet


Also we have "open source" experimenters in need of equipment ( India and other places)
And probably funds too or at least parts





Not just one mans opinion
