the reference to recent "bets" here made me take another look at a Post On EF the other day

Quote

It is suggested by no less an authority than Andrija Puharich that are hero Tesla was also 'Nutless' perhaps to remove sexual 'urges' and so concentrate on his research ?
I often wonder if some readers and contributers to energetics I would be very happy to name might like to urgently consider the same procedure ? (in the interests of science)

I have removed the posters Name [since he removed the post ,but it was copied by another member]

careful with the bets...... :o
Hmm it's full of half truths and misleading doctored science facts, a bit of a time waster and would be better of placed in the bin  :-\ that's my opinion sorry.

Watch this if you think its all crud !
But don't get up set by this guys first comments.

Hi AG. Before he turned on the relay his battery was sitting at 13.13V, and
at the end when he turned off the relay switching his battery was reading 13.03V.  :)

In the video when the relay is operating, it is chattering away at a pretty high frequency, and
it is producing big switching spikes and arcing. This high frequency spikey noise it produces can make
digital voltmeters read incorrectly. :) Not sure if analog voltmeters will do a better job when subjected to
this kind of spikey noise, but they might. Notice in the video how the voltage on the digital voltmeter
is sometimes reading high and sometimes reading low while the relay is running. The green sparking he is talking
is almost certainly due to the metal in the relay contacts. His contacts looked like brass or similar. I have noticed that
metal with copper in it tends to produce greenish colored sparks.

As soon as you disconnect the battery from the source of this kind of spikey noise (disconnect the relay in this case)
the digital voltmeter can show quite a different voltage reading. The guy said that if he leaves the battery sitting for a long time
its unloaded terminal voltage comes back up to around where he started from, but anyone experienced working with
batteries knows that a battery's unloaded terminal rest voltage can be quite misleading as to what the actual charge is on the battery.

In the video he was using a large capacity battery, and if his relay switching is not drawing too much current, a short run of even
an hour may not discharge the battery very much. This is why I suggested earlier on in this thread that you should probably run these
battery self charging circuits for a day or two steady, and then test to see what the charge is on the battery. A way I test the charge
on batteries is to connect my battery trickle charger to the battery and see how long it takes before the charger indicates the
battery is charged. That is maybe not completely reliable, but it seems to work fairly reliably in determining the true charge on
a battery. The longer the trickle charger takes to charge up the battery, the more the battery was discharged.

I have experimented a fair bit with driving spark gap circuits using a 12V lead acid battery, and I have seen the same thing where
the digital voltmeter doesn't show the battery voltage dropping, but as soon as I turn off the circuit the voltmeter often shows
a lower battery voltage reading. However, in some cases of shorter runs with the sparkgap circuits, after I finished, the battery
did seem to rebound back, and when I put it on the battery trickle charger it showed the battery was fully charged. This was
for shorter runs however. This is why I think you really have to do tests for longer periods of times like at least 24 hours to see
if the battery can really maintain a true charge. Those spikey high frequency high voltage waveforms produced by arcing may
actually put some sort of 'surface charge' on a battery in come cases, but it may well not hold up for much longer runs.

All the best...

Yes as the guy puts pressure on the contacts he is ether drawing out the on time or the off time and the frequency goes up where the gain goes in voltage goes up or appears to. Another video of Nelson Rocha does the same sort thing but he has a resister and a capacitor in the coil energizing circuit and a cable tie adding pressure to the coil contacts to alter the wave form.

You tube says Nelson has 70 vids

Digital meters are notorious for showing incorrect readings when using any circuit involving sparking.
To see more accurate measurements in real time, if you don't have quality scopes, use an analogue meter instead.

Cheers.

I hope you not going to do what I think you are with those coils are you  ;D ;D ;D ;D ;D ?

Cus I hope your going to have a fly wheel with a magnet through the fly wheel with N on one side and  S on the other and a split coils out of phase on each side to cancel out the drag effect are you  or not or it will have drag losses lenu's law stuff ;D ;D ;D ;D ;D ;D ;D ?

I have some fly wheels some one turned for me but it needs some way to mount through magnets in them or on them if you get my drift' ;)

How NOT to make a commutator....

LH, poor moulding method caused a shrink in the resin going below the Coppers edge.

RH, The Copper failed to adhere to the resin and moved during the machining operation.

Number 3 is curing as I post....

Cheers Graham.

Hi Grum. Very innovative. Too bad the first two had issues. Hopefully the third time
is a charm. :)


@Brad, the coils and rotor are looking good.

All the best...

Hi Void.

Sadly, not to be....

The resin shattered during machining possibly due to us having a heavy frost last night. Yet another curing as I post.

Six coils to wind, the kitchen table preferable to the un heated workshop.

Cheers Graham.

Hey grum

Its better to not put so much hardener and let cure till the next day. Will have less shrinkage.  Also if you have a supplier for marine near by try surf board resin. less shrinkage. and Im not sure what you mean by machining, but if its a lathe its will be better if you us a sanding block to whittle it down. Coarse to get it close then fine to get it smooth. If you can water sand it on the lathe it will help prevent build up on the paper. Just some tips.  The surf board resin is close to glass clear when cured.

Hey mags.

Thanks for the advice. Chet also mentioned the nature of this kind of resin via Skype, just now.

Well despite a minor crack the assembly has just passed a 5000 + RPM speed using my bench power supply consuming under 80 Watts. I had to replace the motor shown in an earlier photo, smoked it!!

The new motor is an old school field wound series connected unit and uses around 8 Watts @ 2000 RPM.

Brushgear to follow....

Cheers Graham.

Some forward progress.

Now the REAL work begins.  :)

Hmm.... my 1000th post, an omen??

Hi Grum,
Beautiful work , wire your coils so you have three seperate machines.
Offset their fields, and you can use the spikes to work with the seperate fields.
Sorry I'm not very good with words.
Thanks art v
