As I promised in my video "EL Wire Made at Home" .www.youtube.com/watch?v=AcXHx5ikjM4 I came up with a few circuits for building your own power supply for electroluminescent wire. The first one is very similar to the "tickler" style 1908 Ford Model T spark coil http://en.wikipedia.org/wiki/Ignition_system#Switchable_systems
<p>I've read some of the instructables (and other tips) on quieting down noisy EL wire power supplies. Will building my own help in this regard? Meaning, would using a different circuit or with &quot;better&quot; components alleviate the high pitched whine of the cheaper supplies. The 12v little cube I have (from Chinese ebay seller) appears already expoxied/sealed but still noisy (I'm running 12v LED strips as well as EL, thus needing the 12v version).</p>
<p>We made a working version that goes from 9v to about 150v, driving a meter of wire nicely. We got most of the parts from an old clock radio. It's tough to read the schematic in the video, but the following worked for us:</p><p>Resistor at the bottom (on the base leg of the transistor): 33 ohms</p><p>Resistor in parallel with the capacitor (left of drawing): 1 K ohms</p><p>Capacitor: 10uF (I think the drawing shows 6.3)</p><p>Transistor: NPN - unknown harvested part, but an NTE 123AP also worked.</p><p>For the transformer, we reversed the step-down from the clock, which had a single primary winding (700ohms) and a pair of secondaries (5 and 8 ohms). We bridged the two secondaries together and applied the + voltage in the middle. We found that the secondaries were wound in opposite directions, so we had to crossover the leads or it wouldn't work.</p>
is it posible for you to post the cercet. I have a hard time seeing hers and would like to have it right in front of me when working. if you can do that, that would be great.
*circuit <br>rofl idk what I was trying rofl spell there.
<p>Here's a schematic, as we built it.</p>
<p>Thanks for the info. Great explanation of how EL works.</p>
love the video, I was wondering if you could put up a schematic. its really hard to see. all in all very nice!!
<p>Hopefully you didn't already address this, but do you have this circuit posted somewhere? I want to try and take a closer look at it before I take the plunge and try to build it. BTW - Great video!</p>
<p>Hi</p><p>I'm working on a new project which will use about 200mm (8&quot;) of EL wire. In Ireland we have 220v ac. Can I just use this supply to power the wire or should I use an inverter of some sort?</p>
This video is helpful and has even inspired me in a new project. Thanks so much!
Thanks for the EL instructable. I'm interested in EL and now you have saved me some time in researching EL. <br> <br>You should try improv acting.
Nice video tutorial. Is that a 2N2222 NPN transistor? I'd really appreciate if you could post a detailed schematic.
that sic yo something new to learn
can you use a modified flash unit from a disposable camera?
Very good info. Thanks!<br><br>NeuroPulse: this is one of those plugin night-lights. you can get them at home depot, etc
Wonderful! <br>Can we use a Compact Fluorescent Light circuit from a cheap &quot;silly straw(R)&quot; bulb to drive an EL display?
your camera has a death pixel
Nice. I've used a variety of similar circuits to light fluorescent tubes. I think it's time I made some of this 'EL Wire'.
Yay! Glad to see more posts to Instructables!<br><br>Is that an electroluminescent panel or is it just EL wire in a flat box? I would love to know how to make EL panels.<br><br>Thanks :-)
