Joule Thief

[innovation_station]

if we want to advance this .... can some one look into useing a 9v battery dropping down the voltage...  to 1.2 -.5 vdc ... 

and in the process makeing more amprage available  to the unit to switch hence increaseing out put ....

ist!

i may be able to find a few fets...      to do this ....  key is to keep the spikes with in working range ...     so you dont start popping fets...

This is the same circuit as my other joule thief video. This time there is a secondary coil off the big toroid (which is still run in series with my mini toroid.). The secondary is connected directly to a CFL. I noticed that when I run the joule thief circuit, just the motor and LEDs work, but when i disconnect the battery the CFL flashes. I spose theres some back EMF that does this. I've tried disconnecting the motor and LEDs to see if the CFL will light continually, but to no avail - it doesnt even flash on disconnection. Anyone got any ideas on some modifications i could make to get the CFL to light continously on my 1 AA battery?

@flathunter

where did you get that core...... that is huge ..... 

i want 1 lol

but im cheep ... 

you need high self inductance coil  to get a nice hv kick from the colapse ...  that will power the cfl

you get a small one from the motor windings.... 

you can add additinal CHOKE COILS... as you see fit to enhance this effect ....

@ ist

Good work ! looks real nice.

@koen

The current is the same in all the coils .


@flathunter

Nice video , great work !

@all

I said that in the end , sharing and success  for all was my goal , i am happy to see it happening , we may have to fight to keep our pc running tho.

Why don't you make the slayer007 circuit?
