Aromaz, check this page out, particularly the comments under the heading "Negative Resistance"

Aromaz Ice Machine???
Aromaz-- I was not going to say anything because of possible ridicule but I noticed that the coil was cold the first day that I ran the experiment. The 2n3005 is the hot part on mine also. The day that I noticed the cold coil I had just watched something on tv about endothermic vs exothermic chemical reactions and wondered if this phenomenon would apply to electronics. If we pull energy into a system from the environment rather than releasing it the effect may be coldness rather than heat. I read somewhere that Tesla could heat or cool a room using one of his systems.
Ren-- I like your bright light. I got similar result with the inverter that I built a ways back. It took about 1.5 amps to get the light to come on blinding bright. If you feel like it give us a sketch of your circuit. I am able to run Aromaz's circuit on about 70 mili amps at dim light and have not been able to get super bright light out of it yet. I can get good light in multiple bulbs at about 300 mili amps. I will try Gino's idea with the 2222 base and see how that works.
Bodkins-- I will try to run this with no 2222. You may have been able to do this because all the transistors are bunched together. A feed back thing?
Does anyone know why there is HV all over this circuit? Can or should we try to get rid of it? My version of this thing is a real shocker.

Fair enough Aromaz, I never know just how far people are in their understanding and knowledge of all things electrical. It pays to question these things to make sure we are all on a level playing ground so to speakOriginally posted by Aromaz View Post@ren: See my posting #1301 for foto and details.
I do share your sentiments. And I did check with two different brands of digital multimeters as well as 50 mA scaled analog. You can zoom in on settings of the digital amp meter. I have done multiple SG and SSG Bedini's thus I am aware - and sceptic of measuring instruments; but that is the only option we have now. Further, after running 11 CFL's through 8 hours of 'going home' plus all play yesterday with various modifications using only my smallest 12 Vdc Lead Acid battery, the voltage went down 1.72.
Looks like you have correctly measured your devices and you are aware of the questionable state of some meters. Sorry to butt in gents, please continue
PS: Here is a pic of the toroidal PWM circuit I have been playing with. I was aiming for maximum light from a low voltage source. If I switched that light off the room was totally dark i.e. that light is the only source of illumination in this photo. No long exposure either, we all know how pictures can be deceiving. I simply covered the flash on the camera with my finger. I might make another video soon, the light is too bright to look at directly for any length of time.Last edited by ren; 06-13-2009, 12:40 AM.

Impossible readings
@ren: See my posting #1301 for foto and details.Originally posted by ren View PostTypo? Point 62 of a milliamp (0.62mA?) 62 milliamps? 620mA? What setting is your multimeter on Aromaz, and what is the reading? Ive said it before too, all of these measurements need to be comfirmed with a analogue gauge. I dont even use my digital for amp draw any more.

@ dulcet tones
Hey bodkins, I just loaded up your #30 vid, nice scope shots. The missus dropped stuff in the kitchen when your voice came on. Tee hee. My brother coming over for the weekend, see you guys in a couple of days. Take care.

i guy's i found a solution for "2n2222 base" question
i hanve connect at hv output
amazig boost in the light
the leyda jar i think is replaceable with neon bulb or spark gap or any stuff help you to find the resonance
p.s. the leyda jar singAttached Files

Open base on 2n2222 or not
The circuit that I showed in my last video has the base of the small 2n2222 configured in two ways. Either open (except for a clip lead attached) or it is connected to a 5M pot that is led to source voltage. If the base is left open it usually needs a kick start to get the system running but once running the thing runs at about 70 mili amps, the whole circuit becomes electrified with HV, and you can light multiple CFLs. It is that configuration that has me facinated. I think that in this setup it is feed back that triggers the little 2222 and that the trigger energy is being transmitter----THROUGH THE AIR. Also to get the amount of energy that we are seeing----I think that we are getting help from mother nature. This coil is going into a resonance and opening a door.

Re: linking coils together..
Came across this site a couple of days ago. See if system still self oscillates with a variation of the dual coil schematic.
RMCybernetics - DIY Homemade Ignition Coil Driver
I think I may make a mini tesla transmitter as in patent 1119732.. All the tesla coils I see recreated leave out the tube being same length as secondary. And max area thus max capacitance of transmitter 'globe'
Also going to make a few caps, just 9 inch square Alfoil glued either side of 10 inch square window glass.
Ps, vacuum diodes thus far: not able to make high enough vacuum.
