Blocking Oscillator/Charge Pump/Astable Multivibrator

[astral]

Overview:

Hello everyone! For awhile I had been trying to have a simple circuit with low voltage input that would start an astable 555 circuit off 1.5volts. Now after reading many and many pages of material here on the forum, I decided to take some basic ideas, connect them and see what results would be obtained.

The overall circuit is three sub-circuits connected in series. Please see the schematic attached. I drew the thing, because to tell you the truth I love to draw and it was much simpler than the programs on the market.

Moving forward:

Stage I:
Blocking oscillator/Joule Thief composed One 1.5 volt AA battery. Inductor, iron ferrite [Green toroid from computer power supply] bifilar 18 windings of cat5 twisted pair wire. R1 is 220 Ohms resistor. Q1 is 2N4401 transistor.

Stage II:
Charge Pump composed of D1, D2 are 1N914A Diodes. With C1, C2 are 220uf electrolytic capacitors.

Stage III:
Astable Multivibrator at 100us or 10khz. Composed of decouple capacitor 220uf electrolytic. R1 is 1 ohm resistor. R2 is 100 ohm resistor. C1 is 1uf electrolytic. Plus the TS555 timer.

Simple enough right?

The idea was that the end result would be, circuit that could be used to trigger other circuits, exciters, joule thieves, etc.

What I wasn't expecting was the significant “current gain” that was achieved this action of staging these circuits in this particular fashion.

Readings from Multimeter per stage:

Stage I: New AA cell

Volts 1.45 ref GND
Current Draw 110 MA

Stage II:
Volts 3.75
Current 200 MA

Stage III:
Volts 3.75
Current 200 MA


Now the interesting part: When these are connected in series, if you measure the current off the 2N4401 collector there is a whopping 1.45 AMPS! At 1.45volts!

I've been able to power some interesting sub circuits with is layout.

Replication is needed.

Any thoughts?

Update:

I just acquired some images of the input current and output current of this circuit on my bread board.

I know these are crummy images but its the best that can be done at the moment.

Hi,
I did do a Rebuild with a N555 and some fast Diodes. My Power Source is a Powersupply, where it shows, what it consumes.
But it did not work for me. I can read at the Points you are refering too 2,1Ah,
but only with the low Resistor on my Meter for mA.
When i plug it into the 10Ah Resistor, it only reads 0,2Ah.
At the same time, as i put this Load on it, the Power supply shots up with the consumed Amps to 2,2Ah.
I did try a 5W/12W Bulb also and it consumed at 4V still 0,2Ah more.
It looks pretty 1:1, what it takes and provide for the Load.

So i assume you take it from your Batterie. Some of them have a Capacity from 2Ah. So you may can run it under heavy Load one Hour or 2.
But when you would connect a 5W Car bulb on it, it would not run to much Time.
The 2Ah what it does reading seems more is a measurement error on the Multimeter.
