Self Running Micro TPU, with closed loop.

Now if you can tell me how to further amplify the signal, that is what I would like to try.

burce did you try a magnet to amp the effect? put a magnet on the feroitte then smak it at the right speed


i still dont think much of this is needed  in a tpu maybe in a steven mark tpu

Hi hakware,

Welcome...  I'm a newbie too.  I think most are running at 2hz, but I hope someone will try 7.5hz to see what happens.  I believe the frequency depends on the RC circuit.  I don't have a ferrite core, but plan on getting one soon.

@all
Anyone recommend an online site for getting cores?

I recommend using one transistor and one LED to keep the circuit simple and reducing the size of the supply capacitor to reduce run times. I think we should focus on the frequency, coils, and cores.  Speaking of coils, can someone explain to me what the "trigger" coil does?  It seems that the transistor is the trigger.  Has anyone tried the circuit without the "trigger" coil to see if it is doing anything?

Thanks,
4Tesla

@4Tesla
I could not agree with your statement that I bold faced, more!   
I will gladly try your tuning to 7.5 Hz.  Please draw me a diagram and placement idea.  Need values on Pot (saw, 100K) and type of cap.  (ceramic I suppose?) Thanks!

@IS
Thus far a magnet(s) have no effect whatsoever.

@ALL
Reminder, I am using only a 1000uf cap, and a nine volt battery.  I have 8 LED's that self run for nearly 30 minutes.

Cheers,
Bruce

EDIT:
@4Tesla
I have tried no trigger, and it will not work.  Also, I have my Transistor complete opposite from EM's original drawing!  Everyone says it should not work, but that is the ONLY way it works in my setup.  You can read the description I wrote to Wattsup as to where everything is hooked up.  My emitter is where my collector should be and the collector where the emitter should be.

@ bruce lol

do you know why??

it has no effect ?? the magnet ??

@btentzer

Tried your set-up but with my present 2N2222 transistor and still no go. I am going to get a few other transistors.

It has to be my coils so I will make some others this weekend. I think my trigger coils are too big or long and are hoggy up all the  juice.

I tried spiking with 9 volts but just keep blowing leds. If I only use one led, should I still spike with 9 volts or must I use like 3 volts instead?

Do you have a part number for your ferrite?

In the tests that I have actually done to I have noticed, that the device doesn't probably produce any OU, in how much the LED pulsates with brief flash that a few milliseconds duration.
For example, with 1000uf electrolytic capacitor, if the LED pulse 4 times at the second (4Hz), if the duration of flash is 2 mSec (The pulse time I have been able to measure through an oscilloscope), we have 8 m/sec * sec of working time. After 4 minutes with 240 Sec the total time in which the LED has been turned on is 0.08 * 240 = 1.92 Sec.
For example i simulate the circuit:
a generator of impulses with a basic frequency of 4 Hz and once of impulse of 2 mSecs, This means that the LED stays turned on for 2 mSecs every 0,25 Sec. With a button I have simulated the loading of the 1000uf electrolytic capacitor.
I start the simulatro circuit, loading the capacitor by pressing the button and I verify with what speed goes down the voltage to the heads of the capacitor.
In my simple experiment the voltage of the condenser reduces him of around 1/10 V every 15 seconds, Therefore later around 800 seconds (12 minutes) the led is not more visible. If the frequency of pulsation of the LED is smaller, for instance 2 Hz, the time doubles (24 minutes), if 1 Hz, 48 Minutes.
This simple experiment brings to the following considerations:
1. When you verify the time of operation of the LED, it is fundamental to verify the frequency of pulsation.
2. Is opportune to verify, with an oscilloscopio, the real time when the LED is on that to make best verifications.
3. During my experiments I have built only a nice pulsating LED, whose energy is only due to the energy of the condenser.
4. I would not want that who declares an increase of the time of operation, in reality, you is reducing only the frequency of pulsation or the time when the LED turned on.
5. For times of operation under 30-60 minutes is extremely unlikely to have produced some energy from the device!

@EMDevices

I would like to know from @EMDevice if the frequency of pulsation were always the same one and if he has measured the current absorbed by the LED during the cycle.

You have succeeded in repeating the experiment other times with superior times to 2 hours (7200 sec...) ?
Has calculated the real energy absorbed by the LED ?
