Generators

[audioguru2]

Steven,
Are they in parallel or in series?

Since you like loud bangs then BE VERY CAREFUL and try powering-up a big electrolytic 1000uF/100V connected backwards to a high-current supply. If you are not injured too badly and can still hear, then you'll be cleaning it up for months.

re audio guru, there all in parralell, audio guru, i like exsperimenting, im useing the microwave oven motor/generator to power these up. and i wont use the mains , as i kinda like this one to be portable, like my other high voltage circuits , which they run off a 12 volts lead acid cell rechargeble, battery, ill be biulding a sieries one latter, when i can get more parts, as our dicksmiths electronics stores in australia are no longer stocking many parts, and there phaseing them out ,

In these pictures a length of pvc pipe is used to house the microwave oven motor/generator. in one picture taken from the opisite end youll see the rear of the microwave oven, motor/generator. and a microwave oven filter circuit, that i ended up leaveing this out as it puts a load on the motor/ generator, makeing it harder to turnin the other 2 pictures, ones a side view showing the brown plastic motor turn peace , protrudeing out the side near the front strut suport, you only need to rotate the turnpeace half way botth ways to charge up the high voltage multiplier circuit inside

in these pictures, above view showing how it looks and with the suport leg struts in place, and in the second picture the long high voltage multiplier circuit board supports allready glued in place and an a bare circuit board which i put in to show.

in these pictures the end section not yet sealed , showing the terminals for the output fitted . and the wireing yet to be cleaned up more and in one of the other pictures the front end sealed up with a peace of round pvc , made from a pvc pipe. onece thats all finished, then a few coats of varnish will look good .

In these pictures of a second, hand powerd high voltage output generator. i put my mini marx generator . between the output terminals, each high voltage ceramic capacitor is rated at 6 thousand volts, and the 1m resister is 1/2 watts. every few half rotations of the turn peace on the microwave oven motor/ generator charges up the high voltage multiplier inside the pvc pipe, houseing then, this output via the 1m resistor ,, charges up the mini marx then it fires off a fat reasonably loud arc between the gap.

in these pictures i used a small hv multiplier circuit that consists of 3kv ceramic capacitors and 1n4007 1kv diodes, and the small black thing is a push button piezio electric ignitor from a portable gas oven electric ignitor. so in this circuit setup i hold the piezio electric ignitor in my right hand and repeatedly press it about 12 times or more. the output ac from the ignitor is multiplied by the voltage multiplier circuit. the hv ceramic capacitors hold enougth voltage to give you a better shock than you would get from the arcs of the pizeo ignitor, alone.

in these pictures is the lates generator , all installed into a pvc pipe with leg struts, one end of the pvc pipe at the top i used 2 screws for the output terminals , and at the top front end where i havent seald it yet, is the piezio push button ignitor i salvaged from our gas stove portable hand held lighter. the inside of the pvc pipe body , is 2 quarter circle pvc sections to sit the short high voltage multiplier circuit on , of which i tacked into position with hot glue, useing a bostic glue gun. this handy unit i just repeatedly push the black piezio ignitor , for about 12 clicks or more, thats the ignitor you push till it clicks and the output from it is multiplied by the hv multiplier circuit and the charge stays there untill i discharge it . i can use the small arcs from this to light the gas stove . when matches aint around to use. when i put my fingers across the output screws, after ive pushed the ignitor a number of times it sure puts out a reasonable electric shock. sometimes prity awsome

although not finished yet this more compact hand powerd generator , will have 2 circuit boards inside it, as shown in one of the pictures, ones a high voltage multiplier circuit to multiply the output ac voltage from the microwave oven motor, the other cirvcuit board when finished is the full length parralell capacitor stack , so when the boards are filled to the end these will be inserted and fixed into the pvc pipe houseing, upside down and above each other, the parralell capacitor stack has a 1/2watt 1m bleeder resister to charge it up so at 630 volts the current will be higher. on the motor turn peace i fashioned a pvc lever to make turning more easyer , the front end of the pvc pipe is flared out to an oval shape to make more space. inside the pvc body are 4 pvc quarter sections fixed in place and modified to holde the long component boards, the unfinished parralell capacitor stack i tested before , chargeing it up from another high voltage multiplier circuit powerd by another hand powerd generator , and it sure works good .

Mixos, off subject, but your penguin cloth on your table is awesome, best thing since sliced bread!

 

[audioguru2]

Quantum,
Actually, that is the work of Steven, as reported by Mixos.
I was going to mention those penguins too. With that much high voltage, they will fly!
Have you ever seen a penguin fly? They can't, look at those tiny wings.
Notice that Steven uses his finger instead of a voltmeter. Ouch!

 

[steven2]

re audio guru and quantum\ thankyou for such a good peace of humour this was the best contact paper i can get for my work desk as i had to get rid of the last contact paper before that, as it was metalic highly conductive and i had a lightening storm on my desktop as the arcs from my high voltage exsperiments was arcing to this conductive desktop , it was awsome , i can asure yous these pengiuns wont feel a thing as there none conductive as pictures, on this latest contact paper,

 

[audioguru2]

Steven,
If you get your voltage high enough then anything will conduct, including those penguins! ;D

 

[mixos1]

here are the resisters id like to have identified and like to know if they are 10 or 20m

[steven2]

: re audio guru oh i forgot about the puncture voltage yes your right, those pengiuns would be toasted, say how do you like them choose from the following, well done. medium .rare or . do you like crumbs , batter or flour,

 

[steven2]

ive made a boo boo some where here are pictures of resisters i was ment to go to the parts general reqest section but i dident know how to do that so they ended up here, im looking into makeing a high voltage devider circuit but these resistors were amoungst some sent to me by a contact and i like to know there values as my resister colour code calculator dose not cover that many bands and i havent any info to check them

 

[quantum1]

If I am not mistakened, just put the first three bands together, multiply/ divide the number by the fourth band.

reply to hotwater wizard, sorry for the delay thankyou hotwater wizard this was realy handy the information you gave me.

from steven with the final completion of my latest hand powerd , generater with the full length high voltage multiplier circuit and 20x 630 volts 0.33uf capacitors in parrallel all in the one unit i found that the microwave motor ,used as a generator ,if it has a plastic shaft with plastic internal cogs,although there hard to turn , but with the turn peace if you rotate it hard enougth that after a while the internal plastic cog easily gets damaged. so it may pay to use a motor generator with a metal shaft,

 

[mixos1]

in one picture is the high voltage multiplier circuit inserted, and allso the 20 stage parralell capacitor board. fireing this up resulted in 20 x 630 volts capacitors blowing so i took out the parralell capacitor setup pending on some investigating. so if i reduce the 20 parralell caps down to 16, would be better, as i tested this when i had 16 parralell caps and it allways fires with a bang when i shorted them , in the picture some of the 4 extra caps dident go flatt to the board , and dispite blowing 20 caps which i think was a bit to many to have , the hv multiplier circuit still fires up good , and even charges up my mini 2 cap marx generater, which firesa good loud fat arcs. in one of the pictures i decided to dress up the hand powerd units, pvc houseing with bits of white pvc shaped to fit.

Steven,
When you parallel two capacitors, the voltage rating remains the same, not doubled. But the capacitance is doubled.
If you put two equal-value capacitors in series, the voltage rating is doubled, but the capacitance is halfed.

Hi Steven,
I'm sorry that you blew-up all those nice big greencaps. I think that your voltage-multiplier fed them too much voltage.
If turning the motor produces AC, then its output needs a rectifier to charge those capacitors. But keep the voltage within their rating.
