High Voltage Generator

[bubber25]

hey i got a lawnmower i dont use anymore wheres the magneto motor on this sucker so i can take it out and experiment

[prototype9000]

@bubber25 under the cover on your lawnmower mounted next to the flywheel just follow the wire from the sparkplug to it

[HorizonDelta]

Good vid ! More Tesla tech in "Wonderful electric lightinn" bu HorizonDelta ;-)

[achemachew]

NICE.



[zker666]

im making fun of your bench. Lol jk

[prototype9000]

you made the bench sad

[zker666]

i know this

[zker666]

@prototype9000 mine is much worse lol

[matiss234]

can you power tesla coil with it ?

[prototype9000]

you could with some proper tuning and using more than one powering a very small tesla coil

[prototype9000]

you kindof have to test around for the primary one side of the primary will usually be free glued to the side of the magneto the other will be bolted to the metal inductor connected to one end of the secondary sometimes they are hidden and just have to put a wire on the metal even though you cant see the others most magnetos also have an internal capacitor they are the first things that stop workingona magneto

[prototype9000]

takea walmount transformer not one over 600 milliamps take it apart take the rectification and smoothing capacitors off then hook it to the primary of the lawnmower magneto from where you unsoldered the rectification using some wires

[prototype9000]

lawn mower magnetos dont work very well from a pulsed 555 timer circuit there made to run on an sine wave its most efficent for them when its pulsed loose alot of performance and the spark gets shorter besides i like doing things the easy way no sense in over complicating something when you dont have to

[wildhart7]

dude, just connect a smoothing cap in series with a 555 timer output in PWM configuration then you can maximize on your little magnetos

[Aeryk333]

I mean not mains voltage, only low mains frequency. It of course is cool to run on low voltage.

[Aeryk333]

Iron cores such as in magnetos dont like high frequencies, too much of eddy currents are generated. Thats why it runs cool on mains. Good job.

but are you using a feed back coil and is the primary just the seconadry i luv high voltage and have had a few shocking experiences

[prototype9000]

no not using a feedback coil just a unrectified wallmount transformer hooked to the primary on the magneto thats it high voltage made easy

[98209276]

this is probaly because of the feed back as you only have one coil i wouldnt be surprized if the transistors blew iether

[prototype9000]

never had transistors blow should see my really big magneto no video yet that blows steel to bits the output does

[98209276]

what circuit were you running it off

[prototype9000]

im using anunrectified 12 volt 800mA walmount transformer i took the rectification off because one of the smothign capacitors blew magnetos work best off from a sign wave wich ac is a sign wave

[prototype9000]

yeah i also tried pulsing it wiht a 556 at 6 volts witha voltage comparitor and it just made the core over heat and the wires melt i went threw 6 magnetos before i figured out what was goingon a sign wave lets it run nice and cool for hourson end go to highwitht he amperage and it melts things to i guess you could pulse it if you have a diode im thinking inductive kick back could bethe overheating problem when its pulsed i dont know

[98209276]

is that a magneto off a pistion engine?

[prototype9000]

its a magneto from a common lawnmower
