Donald L Smith Device

[Void]

There is a replication of the Don Smith device which was posted few years ago.

That is not a 'replication' of Don Smith's circuit as the circuit shown in that video by BlueSerge obviously
has a number of significant differences from Don Smith's circuit. You can see that components are connected
differently and BlueSerge's setup also appears to use as many or more turns on the primary than on the secondary (possibly step down).

Also, as anyone who has any experience at testing these type of circuits would be aware, it is a major mistake
to attempt to estimate the output power based on how bright you think a bulb is glowing, especially
when the bulb is being driven with a signal that contains all sorts of high voltage spikes from spark gaps.
That is very deceiving. The output power is probably a fair bit less than the input power, but measuring the
output power with any degree of accuracy on a setup like this that uses one or more sparkgaps is very difficult
to do. These are not at all easy circuits to do meaningful tests with.

I had communicated briefly with BlueSerge a few years ago shortly after he had posted his videos, and he told me that
he accidently touched a high voltage capacitor lead and got a very bad shock, and that he had stopped all his experiments
with that type of circuit because of the bad shock he got. The warning I gave previously here about high voltage capacitors
of relatively large capacitance values being dangerous is for a good reason. You have to really know what you are doing and be
super careful when working around capacitors charged to high voltages.

On another note, the rising 'trumpet' voltage waveforms shown on his scope in the video are common waveforms seen when
using a sparkgap circuit. It is no way implies anything unusual is going on.

Hi there guyz

A replication of Don Smith's Device.
Used a schematic of Cloud (chinese) which has a video on youtube, will link it down in this post.


This is my attempt on replicating only the First half of the device with extraordinary results .
Must be tested and experimented on, Whom is ready to do this one , pls be safe , this one can kill,
those HV Discharging caps and Spark gap is no joke.

This is Cloud's original video with working device showing a equiv. of 660 watt loading at the end.

Cheerz~

Absolutely AMAZING that he can get so much action from just shorting out adjacent turns!
That Don Smith replication has to be putting out a LOT of juice to do that.

No, that is normal as well for that type of circuit arrangement.
All you have to do is hook up an NST through a sparkgap arrangement to a secondary coil with not too many turns and
you will see that kind of arcing between windings. If you don't have too many turns on the secondary, then
there is a large voltage difference between each turn on the secondary coil, hence the arcing between turns.
All the best...
