For more ideas and inspiration, as well as tips and stencils, check out http://bleachshirts.reddit.comThis is the one I made for my wife, with a combination of bleach and fabric paint. You can see that it bled under the stencil at first. Be sparing with the bleach!I applied the fabric paint in the original design, and I'm fairly happy with the result, and so was my wife. She's a big Deryl Dixon fan.
Black is usually just really really dark blue or red, so it kind of depends on which dye they used. You can get lighter colors by applying heat while the bleach is on the shirt, usually with an iron that you don't care all that much about, but you have to be careful to not let the bleach eat all the way through. Thicker fabrics with a very light misting on the very surface combined with heat can give you something pretty close to white. Check out http://bleachshirts.reddit.com to get an idea of what kinds of colors and styles are possible.

You can use a relay rated for more than 4.5V. Here is a 5V relay that would work if you're in the USA. Otherwise look for a electronic component seller in your area.https://www.digikey.com/product-detail/en/omron-electronics-inc-emc-div/G5LE-14-DC5/Z1011-ND/280371

Since EL wire runs off of AC, is there anything stopping it from just being plugged in directly? If I'm not planning on having it be mobile, is there any good reason to convert from AC to DC back to AC? And could it be turned on and off with a TRIAC? Not for dimming purposes, but to simply turn it on or off?
Got my components, and built one channel of the circuit. I'm a little curious... does it matter which main terminal on the BT131 I wire the load up to? I tried wiring it up one way and nothing happened, so I tried it the other way, and nothing happened, and then I figured out I had a wire loose, and once I fixed that it worked fine. I'm just curious if it would have worked the first way or not. Also, I tried one of these dimmable LED bulbs first:https://www.amazon.com/Feit-Electric-BPA1560-827-L...And it did dim, but it buzzed and hummed if it wasn't at full power.Then I tried a normal incandescent bulb that I happened to still have laying around, and it worked fine with no buzzing. I'm curious if there are any tricks I can try to get the LED bulb to work without buzzing, since it's kin...

I'll upload a picture once I get the second channel wired and clean it up a little.

Thanks for the reply. I'll be using it with smaller currents, at least this time, just to have a way to dim a couple table lamps. Am I right in assuming that I can make this into a two channel if I just leave the blue circuit part off? Or turn it into a 4 channel if I add another one? I'll probably keep it at 3, but I'm curious how modular this could end up being?I have worked with mains power and relays before but not TRIACS or optocouplers, so I'm going to be doing a lot of studying to make sure I do it right.I couldn't get any IL251 or EL814 unless I wanted 1000 of them, so I went with the LTV814.I'm pretty excited for my component order to show up.
I can't seem to find the M5F600 TRIAC anywhere... Is this one similar? https://www.digikey.com/scripts/DkSearch/dksus.dll...It's a TO-92, 600V, 1A. I'll be using it with 110V AC (American) current. Thanks!

Seems like you could use a buck converter instead of the lm317 to get down to 4V. I have one that is not much bigger than my thumbnail that would be able to do it without the massive heat sink.

Yes. I'm currently working on a project that uses an ESP8266-01 from China ($2) that will do the same thing for a pool pump. The Adafruit board looks nice, and makes it so you don't really have to do any soldering, but at $16 it's still just an ESP8266. If you want to just plug it together, upload the sketch, and have a working project then this solution is pretty good.

I'm wanting to do something like this, except that the 30A relay needs 12VDC to switch. Is something like this: http://www.digikey.com/product-detail/en/rohm-semiconductor/BP5037B12/BP5037B12-ND/658553 similar to the HLK-PM01? It looks like it should be able to output 12VDC from 120VAC (our local current). The HLK-PM01 looks like it may need less components to make it work, so if there is a 12V version that would be cool.
Never mind, it looks like the HLK-PM12 is the 12V version of this. I'm curious why I can't find these on Digikey or anywhere else besides ebay...
