school boy project (TheDaftman)

[KyleCarrington]

As simple as it is, it's really quite eloquent of days gone by (though new). I mean that it reminds you of something Faraday or Tesla might have built, and would be a great subject for a nicely crafted, antique looking project, you know? Not that your work isn't good, i don't mean to imply that at all... I hope you get what I mean :) Thanks Daftman.

[giecuk]

you are amazing



[Gigastorm123]

daftmn, can you provide in the description how much volts/amps goes in and how many volts/amps comes out?, like say you hook up a amp/volt meter to the output terminals, measure, then hook it up to the input terminals, to show what the draw is. im interested in building in the near future a meg using some sortof bedini clicky circuit like you have here and looping some of the acsess energy back to a capacitor to keep the system constantly charged and at the same time running.

I LOVE IT! its very close to how tattoo machines run! except we use two coils

[Lukeidea]

Woot!!

Go daftman :)

[MrFreddyv]

this is almost identical to tattoo machine principle!

[2bigHybrid]

This setup is similar to Electrofishing device...very informative and nice to replicate...

God Bless...

[LogicStudioMadness]

Wonderful work! Great explanation, too. Your setup offers all kinds of possible applications.

This is actually how some switchmode power supplies work, among other things. But those use semiconductors instead of relays. I do believe the high voltage transformers in CRT TVs use the back EMF aka flyback effect as well, if I remember my homework.

fantastic man! It took me a whole day to get this video downloaded (im out in the bush) but it was well worth it! great job and thanks!!!!

Hey DaftMan, my old Pop is gonna try and make a setup like your basic circuit here, and feed it with a battery charger and do a pulse charge/conventional charge simultaneously. Do you think that could work?

[Kntryhart]

Always a pleasure to see your work. Clear explanation; excellent presentation.

Hi DM, JustAnElectrician from your forum, glad to see you finally getting around to this! This device is what I have the most experience with, and using a small RS relay I have generated nearly 400v DC into a cap. 380v to be more exact, but it was an old cap and leaks down even at lower voltages. Something my pop had lying around... Anyway, I am re-doing my old experiments with solid state and WAY BIGGER coils, your contacts are rather heavy and reduce the switching speed, reducing output a bit

[electrician725]

but I love the adjustability! MartHale and Lidmotor and myself, to name a few, have all played with this and LOTS of work can be done with one of these at under .4 watts! Lidmotor ran one from a 12V solar cell, 30 mA and charged a set of batteries while lighting a modified CFL. I have done all types of battery charging, it rejuvenates batteries of all types that I have tried. Amazing device!

Great video, and thanks for your salvaging video, finally got me BACK IN THE SHOP to scrap that monitor

[RawVisualsVj]

I used to make electric shock machines from relays ;)

[wizardangel]

adaptable to a trickel charger maby ..Great Post ,, I always enjoy your projects ..Thanks 4 shareing !!

[electrician725]

@wizardangel charges ALL types of batteries I have tried, NiCad, carbon NR, Alkaline NR, silver cell, button (watch) batteries, NiMH, Lithium Ion, oh, and Lead Acid...

NR listed above means Non Rechargeable.

[gadzometer]

Hi mate, good to see you making videos again.

[grodenbarg]

LOL A homemade oscillator relay. These can also be used to drive high voltage inductor devices. >:)

[marthale7]

I did something similar to this with a door hinge. There seems to be some magic in spark gaps... Imhotep has something similar with a relay that keeps doing the same buzzing :-) I don't have it hooked up in the same room with me.

[solorstars]

all it is a relay in a BASIC form nice video :)

[harpbloke]

great simple stuff !! thanks for posting this, i might insulate one of the relays i recycled from a fridge truck, they are reasonably quiet. smallish cream coloured things.

caps with batteries in them ??? my, what are some people like eh? thats desperate. makes one wonder about their intentions, tacky to say the least. scoundrals indeed.

[rroge5]

its a very simple way to make a taser, i suggest you make a spark gap to show us youtube people. =D i used a relay to zap my friends at school and the science teacher couldnt work out how it could work just with a relay and 9v battery.

[Careica]

Good to see you posted new video! I was waiting for new video. Nicely done motor as allway ;)
