Solid State JB's SSG

[imtotob]

Hi Minoly

Lidmotor used a strip of wire wrapped aroiund a mains extension cord for use in trigeering the base in his flip flop inverter

I like the 2nd ssg much simpler and easy to replicate

thanks

Hi imtotob,

Which 2nd ssg? I only show one in this vid.

thanks

@min2oly

Hi

im talking about your first video on JB SSG

and this one the 2nd vid im referring to

thanks

yeah, it always interests me when i touch my bedini and i see the neon glow much brighter when i do. ha : )

Thanks for the upload, it verified an issue with my Protek 6502 scope and coil circuits. i would connect to a non running SSG and a sinewave would come up ! The coils are inducing the AC...in fact, if you touch the end of the probe with your hand near a fusebox you'll see the sinewave. I run tests in our small utility room and the fusebox is on the wall.

What is the freq. of sine wave? It maybe due to the circuit not being "grounded" - no primary connected and scope picking mains 60Hz. However, oscillator running with disconnected trigger is quite strange. There must be potential between the base and emitter in order to sustain oscillation but it has to come from somewhere. Interesting.

yup you got it, we traced it to the house mains. gotta love the internet for getting all the great minds together. Guy pointed me to the 1n914 switching diode - it's providing the base all it needs - I cut it off and the oscillations stop. I think this is a great discovery - no trigger wire necessary, just a tap from the primary + and a single wire. then, just tune by using different batteries on front and back to get the best amplification.

Thanks,

Patrick

picking up stuff in the air? what is the frequency of the wave? Great Stuff! How long is the electric wire? Hope u post some specs of your build for replication.

Ok you all have it down, and are being kind with your questions, the coil is picking up the houses current - 62.5 Hz - my other coils have never picked this up...

the wire was originally 100 feet I used about 25 already. I remember now I picked it up in the garden section, I think they use it for irrigation timers. my bet is this will work with other coils as well, I just have not tried it yet.

Specs all on BM2 :-)

see you there...

the sound of the fire was relaxing, now im good to go to bed hehe

[Migueldeservantes]

what is that explosive noise on the background?

[min2oly]

@Migueldeservantes

That's the fire crackling in the fireplace, sounds louder in the vid...

Hi min2oly-thats a realy cool effect you have going there.I have no idea about the sinewave with nothing hooked up,maybe a radio signal?. But anyway reguards to the second part about not having the trigger hooked up,the coils collapsing voltage spike may be exceeding the breakdown voltage between the collector and base and resulting in fireing up the base again and so the cycle starts all over.Not sure -just a guess,but realy cool either way.Keep up the good work.
