I made quite a simple modification to the sample, adding an auto-changing two-leg Red-Green-Blue LED.<br /><br />The connector is designed to come apart so you can change colours, or packs in case of damage. The plastic tube pulls back onto the battery-pack leads. A small plastic cage comes away in two pieces. (It's used to hold the LED pointing directly onto the ends of the fibre-optic fibres.)<br /><br />So I just wrapped the legs of my RGB LED in electrical tape, placed it in the register marks of the cage, and held the whole thing together with more tape. (It's a temporary set-up.) Then held a 3V coin-cell battery between the LED legs, and voila.<br /><br /><center><a href="http://pics.livejournal.com/chebe/pic/00160ek7"><img width="400" alt="" src="http://pics.livejournal.com/chebe/pic/00160ek7" height="300" border="0"></img></a><br />A look at the connection mechanism. My LED in cage on left, provided LED and sleeve on right. </center><br /><br />The RGB LED is rated for 4.5V, and I think here it really would benefit from the extra power. (Surprisingly it's quite a sunny day here.) Otherwise, yeah, kinda nice. Here, have a video. <br /><br />You can see the colours being produced by the LED on the left, and on the very right at the end of the fabric see how it gets mixed. With a bit more power it would be prettier.<br /><br /><span class="cuttag_container"><span style="display: none;" id="span-cuttag___1" class="cuttag"></span><b>(&nbsp;<a href="http://chebe.dreamwidth.org/68601.html#cutid1">See more...</a>&nbsp;)</b><div style="display: none;" id="div-cuttag___1" aria-live="assertive"></div></span><br /><br /><img src="http://www.dreamwidth.org/tools/commentcount?user=chebe&ditemid=68601" width="30" height="12" alt="comment count unavailable" style="vertical-align: middle;"/> comments tag:dreamwidth.org,2009-04-20:105601:67175 2012-03-14T17:55:11Z 2012-03-15T23:43:14Z contemplative public 0 My <a href="http://www.lumigram.com/catalog/product_info.php?cPath=1&amp;products_id=89">sample</a> from <a href="http://www.lumigram.com/catalog/index.php">LumiGram</a> arrived!<br /><br /><span class="cuttag_container"><span style="display: none;" id="span-cuttag___1" class="cuttag"></span><b>(&nbsp;<a href="http://chebe.dreamwidth.org/67175.html#cutid1">Show&Tell</a>&nbsp;)</b><div style="display: none;" id="div-cuttag___1" aria-live="assertive"></div></span><br /><br />This fabric is very very delicate. You can't really cut it into non-geometric shapes, can't fold it or bend it too much across the grain, or do anything to damage the fibre-optic strands. But as the LumiGram website shows, there are still plenty of things you can do with it. I'm going to try incorporating this sample into a piece of clothing. And if it goes well, maybe come up with a bigger project to do with this stuff. But it'll have to be on a body area that doesn't move too much! Still... pretty...<br /><br /><img src="http://www.dreamwidth.org/tools/commentcount?user=chebe&ditemid=67175" width="30" height="12" alt="comment count unavailable" style="vertical-align: middle;"/> comments
