The question is how long you want to run this stuff. EL wire tends to be very low-power, so you just need some nice solid inverters and handful of serious batteries (or one motorcycle battery, depending on how your'e using this).<div>
<br></div><div>There's also the fact that EL Wire is ~1.50$/foot. If you've got a yard on each of your 128 ports, that's $1,000 in wire alone.</div></blockquote><div><br></div><div>It's about 1.5 feet to a few inches per. Any suggestion for a good place to by? Coolwire</div>

Thanks! Yea, I'm not looking forward to the terminating. I'm even more sad that EL-WIRE wears out :-( </div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

Hello Noisebrige,<div><br></div><div>My name is Gregg Tavares. I'm new to the list. I hope can contribute more than I take.</div><div><br></div><div>I'm mostly a software engineer, not hardware so I'm looking for advice.</div>
<div><br></div><div>I'm planning to build a el-wire display with 128 individually addressable el-wires. (yea, I know it's a ton of work)</div><div><br></div><div>My current plan is an Arduino connected to 8 <span style="font-family:Arial, Verdana, Helvetica, sans-serif;font-size:12px;color:rgb(51, 51, 51)"><a href="http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en537375" target="_blank">MCP23018 16-bit I/O expander chips</a> connected in series w</span>ith 2 of these <a href="http://www.sparkfun.com/commerce/product_info.php?products_id=9259" target="_blank">El Escudo boards </a>on each of those along with these <a href="http://www.coolight.com/product-p/ifw-3294.htm" target="_blank">ifw-3294 power inverters</a></div>
<div><br></div><div>It seems fairly straight forward. I'll take it a step at a time. If can get 1 MCP23018 working with 2 El Escudo boards and 16 el-wires then it should be pretty easy to chain in more of that combination to expand the number of wires.</div>
<div><br></div><div>The question I was hoping to ask is is there a better way? Should be looking at different solutions? One big power inverter to power all the el-wires? Some chip I'm unaware of that handle's more outputs?</div>
