I think you should make a radio controlled boat out of simple parts.First you get a lever and attach a rotary switch to it.Next you would hook up a battery to the rotary switch,you also hook up a radio transformer to transform electicity from the 9 volt battery into radio waves.Next you attach a transformer to a enlouser to transform the radio waves back to electricity then you hook up a motor to a shaft and the shaft to a propeller.Now you make it water tight and you have a R.C. boat!!! -Nick a-k-a "Vanilla Gorilla" | ||

I am finding hard to find piezo lighters in India. Plz let me know to make one electric lighter | ||

You have plenty of them. Just look around. People will give you them at garage sales. Any time a gadget dies or gets replaced, its power supply is often thrown away with it, but just as often ends up in a corner of the garage waiting to be turned into a spark generator. But you can wind a bunch of wire around a nail, that will work fine. Where to find the wire? In an old transformer, of course! | ||

This 'lighter' also hurts a lot. hehe. Actually, a piezo-electric sparker is not hard to find. You can easily take them out of those red lighters w/ the long black end. | ||

Transformers don't do anything with direct current except heat up. For our purposes, we want just a quick tap from the battery. Any longer is just a waste. But if the coil is heating up, you have probably used the wrong side of the transformer. You want the side with the most windings. That will probably be the side that would normally plug into the wall. | ||

So.........how do you make one out of the nail and wire? | ||
| Simon Quellen Field (Sfield) Senior Member Username: Sfield Post Number: 677 Registered: 12-2004 |
You wind a few hundred turns of wire around the nail. Briefly attach the battery to the two wire ends. When you disconnect the wire from the battery, you will get a spark. | ||

Neat so could you use something like that to make a film can cannon? Or could you use a Leyden jar? | ||
| Anonymous Posted From: 70.106.101.39 |
What kind of wire would you use? | ||
| Simon Quellen Field (Sfield) Senior Member Username: Sfield Post Number: 678 Registered: 12-2004 |
An automobile spark coil is bigger than the film can cannon, but not by much. It makes a spark similar to the one from the piezoelectric igniter. A smaller coil wound around a nail will probably not make a useful spark with a spark plug or even a small spark gap like the cannon uses. But it will make a spark between the connectors as they are disconnected. To make a spark cross a always open gap will require more voltage, which means more windings. Any insulated wire will work. Magnet wire (the kind used in transformers) has a very thin insulation, so you can get more windings in a small space. | ||

How bout the Leyden jar? They are pretty easy to make. If you had one off to the side and had the wire going inside the chamber? | ||

i accidentally made a spark by striking a hammer with the nail try to use that in the film can canon ill give you a hundred bucks if you are able to fire it with out derstroying the can =) (Message edited by mnado on January 1, 2006) | ||

i want 2 kno how 2 make a transformer. i need more voltage in order 2 take down the ampage. could u tell me how to do this? can i buy 1 in Ace as a last resort? i kno its been a while but please respond. | ||
| Simon Quellen Field (Sfield) Senior Member Username: Sfield Post Number: 1049 Registered: 12-2004 |
Buying one would be my first resort. It is cheaper than making your own, and has more likelihood of working without hurting you. | ||

Does piezo crystal --quartz can be generating voltage for ever if a load is kept over it. | ||
| Simon Quellen Field (Sfield) Senior Member Username: Sfield Post Number: 1061 Registered: 12-2004 |
Are you asking if putting a rock on a piece of quartz will generate electricity forever? It won't. Electricity is only generated when work is done. So, when you first put the weight on the crystal, you get a pulse of current. When you take the weight off you get another pulse. You have to do work to get power out. | ||
| Kawanna (Unregistered Guest) Unregistered guest Posted From: 221.134.57.66 |
Is the volt delivered by quartz is ,anyway dependent on the size of the crystal or the quality of the crystal. Is there any material better than PZT . can you mark a link which give a detail on this subject. | ||

We already did. | ||

I connected a torch bulb with a piezo lighter , it did'nt glow ---as there is a voltage generated why it did'nt glow. | ||

An incandescent lamp needs too much current. Use a light emitting diode instead. To make light, you need power. Power is the product of voltage and current. One volt times one ampere of current is one watt of power. An incandescent lamp such as a flashlight bulb needs over 2 watts to operate. A light emitting diode can operate on as little as 0.002 watts. So your bulb requires over a thousand times as much power as an LED. | ||

What is Open Circuit Voltage and closed circuit current in piezo sensor device. | ||
| Simon Quellen Field (Sfield) Senior Member Username: Sfield Post Number: 1092 Registered: 12-2004 |
You didn't say which piezoelectric device you were referring to. But since we only sell piezoelectric ignitors (not sensors) I can answer for what we sell. For something else, you will have to ask the company you bought them from. The voltage is 18,000 volts. The total wattage will depend on your fingers, but a couple milliwatts is a reasonable estimate. That puts the current at 0.1111111 microamperes. | ||

I tried taking a little quartz rock, taping wires to either end, putting the ends of those wires about 1/4 inch apart. When I hit the quartz with a hammer, no spark :-(. Is there any way to get a piezo effect with just regular quartz you can dig up anywhere? | ||

why piezo ignitor gives such a low current at such a high voltage | ||
| kawanna marshall (Kawanna) New member Username: Kawanna Post Number: 2 Registered: 3-2006 |
Anyone can help on this: why piezo ignitor gives such a low current at such a high voltage | ||
| Simon Quellen Field (Sfield) Senior Member Username: Sfield Post Number: 1117 Registered: 12-2004 |
You aren't putting much energy into the system by pushing on the igniter with one finger. So the total wattage will be small. That means that if the voltage is high, then the current will have to be low, since voltage times current is power. As for why the voltage is high, consider that you have millions of tiny crystals in the piezoelectric ceramic, and they are all connected in series, and each little crystal produces a millivolt. They add up to thousands of volts. | ||
| kawanna marshall (Kawanna) New member Username: Kawanna Post Number: 3 Registered: 3-2006 |
Simon, Is there a way by which we can convert this output(high voltage--low current)to an output(low voltage--high current). | ||
| Simon Quellen Field (Sfield) Senior Member Username: Sfield Post Number: 1118 Registered: 12-2004 |
That's what a step-down transformer does. But there isn't a lot of energy to harvest -- it's just your finger pushing down on a button, after all. | ||

Two things to remember about low-bandwidth communications media like email and forum postings: 1. It is easy to piss people off when they can't see your smile or hear your tone of voice, and you can't see their reaction and calm them down right away. 2. Don't get pissed at short comments in such media -- give the poster the benefit of the doubt and assume they didn't mean it the way it looked to you at the other end. The corollary is not to post really short messages. Explain yourself well, and with enough redundancy that the real meaning is very apparent. Unless your aim is to piss people off, in which case send the message only to yourself, so you get it off your chest without damaging your reputation. Stuff posted on the web stays there forever. | ||

Well, I wasn't pissed off actually, I just didn't find it really nice, and it didn't sound much of a joke to me. No hard feelings.  | ||

Hello Simon, I have a piezoelectric igniter with a brass cap at bottom i connected a long wire to the brass cap the other wire is short so i added another wire to that i can make a spark gap but it didn't. So please give me the right information. I shall be thankful to you. | ||
| Theresa Simmons (Theresa) New member Username: Theresa Post Number: 1 Registered: 1-2008 |
First see if you can make a spark by bending the short wire down close to the base. Then connect a BARE wire to the short wire, and see if the end of that makes a spark. Then connect another bare wire to the base, and see if you can get a spark between the two wires. You may not be removing the insulation from the wire properly, so start with bare wires. You may also be allowing an electrical path between the two wires, so you get no spark because of what is called a "short circuit". Fingers or dirt can make a short circuit at these voltages. | ||

In advance, sorry for my English and lack of terminology in physics. Someone here wrote about connecting a piezo lighter to a bulb. I have succeeded in making this thing spark (just by accident, as i didnt know what would happen - I'd been just experimenting with the piezo on different things) First you take the piezo part out of the lighter. A short wire is coming out from it. You just connect the end of this to the base (to either pole) of the bulb, and push the button. Voilá, there is a lightning inside the bulb. Note : - you should hold on the bulb's glass, not on its base (otherwise it won't work) - after some hundred discharges the piezo gets weaker and less effective - the thing works with fluorescent lamp bulbs too, but you can't actually see the sparks just the plain flash of the surface - I have a special bulb that is called in my language like 'candle bulb'. Its nothing to do with incandescence; it contains a flame-shaped whatever-metal instead of the tungsten spiral. When you turn it on, a yellow glowing light vibrates on the surface of the metal. NOW, if you discharge the piezo with the wire end close to the bulb's GLASS, an amazing jet of glowing light flashes in inside that kind of "splashes" on the glass from inside. (My question is: does anyone know this bulb and/or knows how it works? In my language it was simply called "candle-bulb") cheerz, Viktor | ||

Is it the kind of bulbs you get from a starter or testpen? Zap that with high voltage and you will see that glow | ||
| viktor pless (Viplex) New member Username: Viplex Post Number: 2 Registered: 5-2008 |
Nono, it was sold as a decoration, nowadays i can't find it anywhere. Its a mignon sized 240V bulb. |
