    button on/off

    do you want just a switch? you say its push on/off does that mean you push once to turn on then push again to turn off? is this for foot or hand? for push on push off try these http://www.jaycar.com.au/productView.asp?ID=SP0718 http://www.jaycar.com.au/productView.asp?ID=SP0656 for foot...

    lockable knobs

    you could probably make your own if you have the time. use a couple of gears from rc cars etc put one on the end of the knoband then make a second knob just beside it put a new cover on the device and voila. or simply putting a piece of perspex over the knobs so nothing interferes with them is...

    Solve the riddle and get a piece of test equipment

    oh stuff it is it a gold plate capacitor? gold is noble capacitors are blue(depressed) and other colours there is nothing between their plates

    do I need a circuit?

    imight go the 25V ones then. ty harald yet again. this is going to help out so much

    do I need a circuit?

    hey harald got a question what voltage rating do I need? I can get my hands on some 10v 16v 25v 50v or 63 v I was thinking the 16v range but thought I would triple check

    peltier devices

    this is my garnd scheme as it stands now. I hope to get a trial run soon. I doubt it will revolutionise the world but I hope it coolsme down in summer lol. if all goes well I will be back on here with pics... if it fails lets never speak of it again lmao

    Step down voltage from 36V to 12V for EV

    I have to counter this question with another, how many amps we talking? if its to start a car engine you need about 100 cranking amps which most step downs won't be able to do. just stepping down a voltage is not the only thing you need to look at, also look at current ratingand let us know...

    Readily Available Energy

    actually i just wiki'ed it. I thought the earths magnetic pole could be used for making a small current, it turns out I was slightly wrong and found telluric current. I can't find too much out on how many volts though or standard current, but I have found that it was used to help telegraph...

    do I need a circuit?

    ok thats new. I am turning the net upside down trying to find a schematic using thedevice or a datasheet, nothing as yet. stupid me thought I simply put this on my 12volt battery and got 5volt out.

    Readily Available Energy

    lol I thought your idea was for lightning originally. but the earth battery was a technic used to boost signal on the old telegraph system. I am very dubious this will create huge quantities of voltage but yet it is another for of alternate energy that is out there.

    do I need a circuit?

    yep will do thank you heaps harald. I always getjumbled up with caps and was trying to figure out the differences between the ceramic and electrolytic, thank you wiki lol

    hey mystic haven't seen you for a while. any way to keep on topic with this thread you wanna make an earth battery? tully might be the best place or Atherton as the soil needs moisture and you know as well as I how wet those areas are. Brisbane is ok place to try it but not having much luck atm...

    do I need a circuit?

    something like that? and then put 2 100nf caps ontop of the 220µf ones? that was just a quick sketch sorry if Its bad but I work better with pics
