Mechanical Resonance (Projects)

@tinman

Sorry again for off topic. I should not have raised the scope question here but will just respond to @citfta quickly. I just hate opening new threads but maybe it would deserve a thread indeed.

@citfta

Yes I understand that basic function but needed to know if there is a specific equation that the scope resolves from the values it receives from the probe and ground. I will start a new thread this weekend on AC and will bring up this question again since the scope does in fact use the AC neutral in every measurement. Thanks for your response.

But here is one small crumb for thought. If AC is alternating current between the hot and neutral, then how is the scope able to measure steady potentials and derive them when the scope ground is actually an AC neutral that is supposed to be alternating during half of every one cycle? If that neutral half cycle is energizing the scope itself at every half cycle for it to function then how can that same neutral, now become an impartial probe ground? Ouch - brain squeeze. Constructs should never surpass logic.

No I am not doing anything with mechanical resonance these days because my plate is rather full as it is. I will eventually do some resonance tests but I am planning to use only a 1 inch length of wire as a secondary and create micro movements around that wire. This will be when I get deeper into Spin Conveyance where if you consider any device that produces any form of output to a load, the last inch of wire before the load is conveying all the potential effects of the device to the load so all the activity in that 1 inch of wire is really the final effect that is transmitted to the load. I would like to see if there is a way to directly produce an outer effect around a 1 inch of wire to produce the energy going to the load and I am sure resonance will play heavily in this. If I can make the dogs swing their heads left and right in that 1 inch of wire, why should I need a complete coil? But I am not there yet. But actually in SC, even primary to secondary resonance in a coil is mechanical resonance because it considers the energy to be physically conveyed and not electron flow based. 

Consider what I suggested in my post about your secondary coil in the fork thingy. Sorter secondary turns will remove the energy quicker with less cancellation potential.

Ask yourself this: Why does a coil prefer that a magnet polarity pass beside it in a perpendicular direction? Why would non-physical electrons care about direction and then how can non-physical electrons then know or decide which direction to flow to create the potential difference in your coil? Now look at E=MC2. It's all mass in movement. Mass can move or it can spin or swing or sway, it's all still movement. But you still need the mass which is physical. So how can a physical magnet move and create a non-physical movement of electrons? Oh but electrons have mass. Well if electrons have mass then that coil needs to change its weight while it is energized because moving mass at speeds of near light has to create some level of inertia. OK, sorry going to deep but hope you get the point here. Constructs cannot surpass logic man. Logic will save you every time.

Just did my first video and will post it this weekend but on a new tread. I don't want it on the JT thread because of all the commotion.

After working with the bending strip and the tuning fork, Ive found I want more adjust abilities. So I am putting this wheel into the mix using magnets as the spring actors.

I wasnt fully convinced that increasing freq with the other 2 examples gave me more efficiency. So Tinman has me beat there.

Will be making drive coils tomorrow that fit the distance requirements of the wheel hole positions. Im interested to see how the drive will be achieved facing the points I make in the vid below. Using 1 magnet on the wheel in attraction to the stator changes freq drastically depending on the distance of movement, something I didnt show on the vid. But the less the distance of the wheel back and forth, the higher the freq.  Wasnt expecting these issues.....

I figured out what might be the cause of the freq change while oscillating down.  Its my magnet config I believe. The mags should be face to face for the spring operation.
Going to work with it as is to see how it works with drive input. May be good, may not. Working on it now.

Ok. Just doing some simple input with a stator coil and mags on the wheel, Im finding the resonant freq point is not a sharp point of max resonance. Meaning it is a some what wide band of resonating frequencies it will operate at. It must be the magnetic spring config where the spring is not linear.  Like if center freq is 11hz, I can get it to ring at 9hz and 13hz, but those outer freq need a boost to get them going and then will follow the input. like if I stop it at 13hz without changing the input, it will need a higher input to get it going then lower the input to keep it going. Odd. And when i get it started by upping the input to get it going, it still seems to want to have the same back and forth throw after turning the input down, which may be interesting as I will discuss that later.

So my next step is to try using the Tesla Igniter pat circuit to see if it will run and find its own best freq.  Will use a reed to trigger timing. I will have my dc input with a large inductor in series with a diode and all series loop with a cap. The reed will discharge the cap into a low inductance drive coil as a pulse. Then after the pulse, reed still closed, the large inductor will charge up. Then when the reed opens, the large inductor will charge the cap to a high voltage for driver pulse.  So we want the cap discharge to be a very quick pulse and after the pulse is done, the reed still closed, the large inductor will limit the current of the drive coil as to not affect the wheel much till the reed opens.  Will be interesting to see if it works. And hopefully it will find the center resonant freq.

Last winter I did some experiments with magnets in resonance in a linear tube. At both sides of the tube is a bounce magnet. The magnetic field of a  pulsed coil makes the magnet(s) moving back and forth. At a certain frequency the magnet is in resonance. My goal was to measure the output of the pick-up coil(s) when magnets in resonance. Conclusion: The very low frequence of 6 to 12 Hz needs an other structure of the pickup coils. When you want to benefit from the lower input power by resonance of the magnet, the output coils have to be many narrow coils in series.
