RESONANCE EFFECTS FOR EVERYONE TO SHARE

[Groundloop]

@najman100,

I got the new switch up and running today. The logic part is using 80mA at 12,7VDC. The fan
is using most of that. The switch was tested with 12VDC input and the load was a 12 volt 25 watt
light bulb. The transistors was a little warm since I run with the plastic box top cover off. With the
cover on the transistors get an airflow and will be cooled. The switch itself uses too much current
as it is now when running without any load. This is probably due to timing issues. I will change the
software so that there is no overlap in the switching. Attached is a image of the almost assembled
unit.

[EDIT] I have worked with this switch into the night now. The "leakage" current when running without
any load is still too high. At low frequency the current is 0,1 ampere and at 1KHz the current is 0,8 amp.
This is really bad. It seems that the Darlington transistors (MJH11022) has too much gain and is too
much sensitive on the base input, to fully shut off. Tomorrow I will put in a normal power NPN and see
if the switch behave better. I will try the high voltage NTE2354. This transistor is probably much better
suited for a switch like this. If this fail also then we have no choice and must use HEXFETs. No modifications
is needed on the PCB, so far. Stay tuned.............

@groundloop

The important is that the programing works as intended changing this to hexfet or other type of transistor  will not affect the design .
Thank you for all the ahrd work

@najman100,

Got the switch up and running now. Had to use HEXFET's transistors. There is one design change,
one 330 Ohm resistor must be soldered between the gate and the source of each transistor. This
is easy to do on the under side of the PCB. No PCB change is necessary. Attached is the Eagle
design files. The software version 1.0 runs well on the switch. (Posted earlier.) I will send all pcbs
on Monday.

@Groundloop

Fantastic stuff. I have a question.

Is a 330 ohm resistor the same thing as using a 330 ohm coil. What if you take leads out of each gate/source and connected each to a small coil, that makes 4 coils that could maybe turn a small rotor so the circuit could "do something" while running and trying to achieve OU on top of what is happening off the traditional output.

Maybe a more general question for circuit designs in the same line of thinking, could all resistors in a circuit be replaced by such a coiling idea. I have always considered a resistor to be a major point of wasted energy because they generate heat. Am I wrong in thinking this way.

Something of possible interest. Last Friday at my shop we had to repair a chemical dosage pump and by chance I had a few identical used units that were removed from clients that had overall system changes. We had to do a quick fix because the client was running this on a 15 home mini-aquaduc so it is always a rush. Anyways the final problem was the circuit board that had to be replaced so I took one from a unit that had a good board but had a bad pump head and replaced the defective circuit. Now this got me thinking. This circuit is pulsing the dosage pump solenoid that I took apart also and brought it home. The pulses are fixed at 125 per minute but very strong dc to actuate this very strong solenoid coil that has great steel mass to initiate a very strong small outward attraction when it is energized. So I am wondering if such a circuit could be modified to receive a FG signal and pulse to faster rates.

If any of you guys just stop by a local water treatment company and tell them you are involved in energy research and you are looking for some used solenoid actuated chemical dosage pumps that they may be looking to get rid of. All of them should have several that are just lying around collecting dust and I am sure they would not mind letting you have one or more for free. The model I have is a Pulsatron Series C. Actually this could also be used for cavitation studies and you could also use it to oscillate a magnet in linear mode inside a coil and try to make another type of linear generator. The solenoid coil is very hefty and is 98.5 ohms and could also be used to do other resonance tests. Sorry for off topic but wanted to give guys new ways of looking for potential sources of parts.

Now to start pulsing this solenoid coil.
