Self Running Micro TPU, with closed loop.

hello all, ive just signed up!

ive been reading these boards for around 6 months now and following various projects in other threads, congrats to hartiberlin for starting a fantastic forums for subjects such as these...

this thread has made me sign up, as i wish to play around with this circut aswell....



@all


i have some questions:

running the circut WITHOUT the coils do you get MORE or LESS running time?

running a DIODE just with a charged CAP gives you more or less running time that running on the circut (with coils)

do you have higher or lower running times if you put like a faraday cage over the circut? thus blocking outside electro sources?


answering this question will prove weither or not we have something "special" here....




recapturing the magnetic field from the TRIGGER and putting back into the circut VIA the capture coil is the aim of the game right?

then we use resistors to step down the voltage so we dont fry our transistor yes?

this then recharges the main cap?

then smaller cap then pulses the transistor and starts the circut up agian?

sorry my electronic skills are very weak.... i only know the basics, calrification on this would be great, on a step to step basis on what happens would very much help me understand this...



thanks

I was looking at a schematic of a full-wave rectifier and it gave me the idea to try with our toroids.  Has anyone tried this?

@MANNIX, AND ALL,

has anyone heard of the recall on christmas wreaths?  it appears the iron wire that they have been made with have been coated with "LEAD"  to prevent oxidation before they were coated with plastic.  i wonder, what lead might add to this wire?

lol

China seems to be a primary exporter of lead lately.

Looks like it will short pretty quick on the primary with diminishing return from the secondary going into the capacitor. I dont think its going to work.
need to put a transistor on the primary transformer lead and have it switch from the secondary. Might work much better.
