piezos

What is a good place to find piezos? I know I can find them in some old computers and cheap toys with "sirens" in them. What other devices readily have piezos installed? (....and please spare me the sarcastic answers about finding them at Radioshack)

Piezo analogue sound

Hi all. I am a newbie and this is my first post so i might be barking up the wrong tree here. Would it be possible to use one of those small piezo-ceramic speakers to play sound e.g. from an mp3 player headphone jack? i am not looking for great quality sound, only voice quality, but i needs to be fairly loud. Many Thanks, Bob

piezo reacting from splitting power to multiple things

I have two attiny85s that I'm powering with a single 3v battery.  One of these is connected to a piezo (so lights will flash when tapped).  However, the second one keeps affecting the power enough to set off the piezo reaction frequently without tapping.  I don't want to use two separate batteries.  How do I split the power between the two without them affecting each other? Thanks.

Using a Piezo to trigger lights?

Hey all. What I am trying to construct is some kind of circuit that will trigger an LED when a piezo is tapped. The reason I would like to create this apparatus is to trigger lights using acoustic drums for my band's live show. I would like a light to go off every time a drum is hit and I figured that using a piezo would be the best way to do this. Any help that anyone could offer in this would be greatly appreciated. Thanks again. P.S. I found this diagram for a piezo switch but I am unsure as how i could use this or even how to make it in the first place. I am very new to electronics.

Where to get piezo igniters?

I have several lighters that I still like, either for their design or intended purpose. But over the years some failed to produce proper sparks with the piezo. For some I could salvage replacements from cheap lighters but not so much for the longer ones - the type to get your bbq or oven going. Here the wire from the igniter is in ne long piece going all the way from the piezo, through the long neck to the flame outlet. As the wires in those piezo igniters are aluminium it is next to impossible to attach a longer wire as usually there is no room for crimped connections and the isolation is a problem too. I also have one particular lighter that uses a slightly longer and thicker piezo igniter, the common ones don't work here as they are too short. Adding more support underneath is a no go as the shorter ones have less travel when activated. Last but not least is one lighter that requires a piezo with not just the little metal cap at the end but with a full metal body for the stationary part. The lighter in question does not work with standard types even if I add a little metal strip to make proper contact. Problem is simply put that like this the standard ones arch over and no spark comes out of the wire. So big question: Is there any supplier or Ebay shop where one could actuall see the various types of piezo igniters and order them in small or single quantities? So far I already struggled to find a source for the crappy standard ones and the only one I found wanted to charge $ 2.95 US per igniter plus postage. Sounded a bit greedy to me considering I can buy a complete lighter with it for around one single buck...

Piezo buzzer for LED flasher? Answered

I have built the flasher found here; https://www.instructables.com/id/LED-Flasher-automotive-or-motorcycle/ It works great with the LED turn signal bulbs on my bike I would like to hook up a piezo buzzer to the flasher that buzzes when either the right or left signal light is on (motorcycle flasher reminder buzzer). What would be the easiest way to do it? The flasher runs constantly when the key is on, only powering the turn signals when the turn switch is activated right or left. The buzzer won't work when hooked up to the B+ and load terminals like it was on the mechanical flasher with incandescent bulbs. I figure the problem is that the incandescent bulbs provided the ground for the buzzer though the filaments. Does this sound right? Thanks. Sorry about the long diatribe.

Piezoelectricity Experiments. Help Needed!

I'm currently experimenting with piezoelectricity.And at the moment my experiment is limited to just a few piezo sparkers extracted from cigarette lighters.The sparker works with observable voltage spike on my multimeter. No voltage spike however when I use the tiny crystal (the size of a zippo flint) taken out from the sparker.I was trying to replicate this experiment (without the oscilloscope):Piezoelectric Rochelle SaltAnother thing, Would continuous vibration produce continuous voltage?It is known that piezo crystals produce high voltage, yet very low current. What are the options to increase the current? Would winding un-insulated copper wire around it (or any kind of contact with conductive metal) increase the current? Apart from lighter, what other surplus sources of piezoelectric crystals (i.e. quartz, PZT, Rochelle)? Can the crystal in RC toys, radios be used to generate electricity? Although there is the option to grow my own Rochelle salt, I'm not looking into it at the moment since it's going to take quite a while to grow.Thanks in advance!

Piezo Triggered LED lighting with a twist!

Hi There are already a few threads and topics on this site explaining how to hook up a piezo triggered light strip, however I'm looking to build a custom drum kit with particular lighting system and i can't find the info I need to build it. Inside the drums I want a constant, static colour of my choice on the led strip (e.g. blue) and then the piezo trigger triggers that LED strip to to different colour (e.g. red) for a quick flash and then back to blue. I would also like to have control over which colour combinations I use, so if i want yellow drums with green flashes, i would hopefully be able change that with a remote. Is there a circuit or a mod of an existing circuit that will handle my needs? Cheers, Owen

How to properly setup an undefined numbers of piezos for drumming ?

Hello everybody ! I'm currently into a really cool project which gives me quite hard times. To begin, I'm a big noob in electronics, but I'm decent in programming. So i'm able to understand, learn or correct myself easily when it's about code, but I'm really in the dark for everything concerning electronics despite the fact that I read so much about it recently... My projet ------------ My goal is to make my own MIDI drum kit. Not a new idea, but the difference is that I want to use lot of pads. I bought some WII, XBOX and PS drum kits that I disassembled to get just de pads. Then I bought an Arduino Uno, not a mega because I'm a beginner and I can totally start with a small amount of pads, also I wanted the perfect solution in terms of compatibility etc. STEP ONE : 1 pad -------------------- So, I first made a prototype with 1 pad, which was very easy to do, since there is billion of officials and unofficials tutorials about how to connect a piezo to the Arduino. So basically, on my breadboard its like that (except im on A0 not A2) : http://learning.codasign.com/images/1/1e/Piezo_arduino.png So I connected my pad to the Arduino with a 1 Mohm resistor in parallel and I made a program which function very very well. You can read it the : http://codeshare.io/VzUGn The only challenge here was to set proper threshold and delay so the signal is clean when I hit the pad with a drumstick, to integrate the MIDI library and finally to find a software that makes the informations i send available in any of my favourites music softwares (Ableton Live, Maschine, ...), this software is Hairless Serial to MIDI, btw. STEP TWO : X pads --------------------------- It's when I'm getting troubles. At first I believed that all I needed to do was to reproduce the same schematic but "duplicate it" x times. So I tried with 4 pads. I used the same strategy on my breadboard : each pad is connected in parallel with a 1 M ohm resistor, but all are connected to ground. You can see it there : http://oi57.tinypic.com/aymsli.jpg The code, take the old one, but just loop on the 4 pins : http://codeshare.io/8Tb6z So here are the 2 issues : - The pad on the left is OK, like with my 1st program, the second one is still ok, the third one I have to hit a bit hard, the fourth one I have to hit VERY hard. - When I hit a pad, it seems it send electricity in others pins, I say that because when i connect the Arduino to a music software, hiting a pad = having multiples notes at the same time. For the hitting force issue, I'vre tried to play with resistances, puting higher or lower values and I got totally lost with that : nothing seemed to be better. About that "leaking" issue, I thought it could be useful to put some diodes, as i heard diodes are usefull when you want to make the current going in one way only, but when i watch some others schematics, i see no diodes and only 1 Mohms resistors everywhere, so I really don't know what is wrong and what to do. Here is the MIDI xylophone someone made and posted on instructables : https://cdn.instructables.com/FB6/VMRG/H4AGICO1/FB6VMRGH4AGICO1.LARGE.jpg I have no idea why this is working and why there is ground directly linked to these analog pins, and many other things i cannot understand. Any help would be really appreciated ! :)
