BWJT

[stprue]

@all interested

Ok I have tuned my novel device/toy to where I want it!!!!

I have an oscillator BJT circuit that will power an LED indefin.....well with normal circumstances 

The BJT is a Kooler mutation but will run on a 1.5-2.3v mini calculator solar panel as long as the components last.

The solar charges an already charged 2.3v@10F max cap and will light an led (not bright) all day and through the night.

The OSC range is around 20hzs-7Khz output

If you choose to build this please try Koolers easier BJT's as pre-rec because this is very tough to tune!!!!!.....but I built this off his most successful version so use his schematic

I forgot....


Have fun with this amazing circuit

if the first pic you posted didn't work.. it sounds like you might be using a rf choke instead of a ferrite inductor..
it will take a higher perm ferrite you you want to light off the battery..
i haven't had any luck using the powder iron inductors..

kooler have you posted the 16ua circuit? i would like to see it if you dont mind.

artic
i didn't mean to dodge you..
i had a 160ua circuit but the led wasn't bright.. it was noticeable
i have some components here in the house i will see how low i can go with the ma's on the led brightness..
maybe i will be able to post them tonight..

sorry for over looking your post..
