Hows things going with your biggo? Have you made it past 6 hours of light yet?

Hi Altrez,

No, I haven't made it TO 6 hours yet.
5 1/4 is the maximum so far.
I made what looked like a mistake and put 2, 47uF 100v caps in series across the battery.
Later I found out that this was 47uF 200 volts not 100uF 50v.
But when I 'corrected' my mistake, the light only went on for 4 + hours. I think it is curious. Have you lit a fluoro tube for longer?
Did you resort to diodes or a full bridge like stprue to make it work?

Do you still have your big one set up with multiple secondaries?

@XEE2

yes indeed i do love your design i have built it useing a small tranisistor ..   

i have improvements to it ....   but   some time when i get there ...

for now anyone herd about the telefone.. power supply tpu .... 

lol

round here when the power goes off most fone lines have some free juice running through them .... 

a friend said something like 70 volts..  hummmmmm

might just work well with the last tpu i posted wich is almost done..  and as built can be hooked up as a mk1 jt or 2 jts   or what ever you choose it is a darn complex device...



ist!

Ok I noticed something today!

You don't need 400v to light a ccfl!!!  It look to be around 370-380vdc but check out this other info.

On my biggo coil you have seen many setups that vary the output from 344 to over 900.  In the next pic's I will you you what looks to me like empty voltage, kind of. When I pull the cap out the ccfl gets a little brighter but my dmm reads lower voltage.  With the cap in it's brighter at higher voltage voltage but my dmm reads higher voltage!   Not in it's like 20v out it's like 160v. Can anyone explain this?

Pic's...I hope there in order!!!

SH?tT there not in order but you can see what I'm getting at.
