If you're struggling the big electronics retailers, Farnell for example, will have them on their sites. Either that or the component manufacturer, the LM parts are out of patent so very generic but I think Linear Technology still make linear regulators. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2385&page=2#post-92753 Thu, 29 Nov 2012 12:02:20 +0000 DaveC 92753@http://citycyclingedinburgh.info/bbpress/ <p>Cheers, I googled the LM517x lastnight and eventually found a datasheet free as most places want to charge to veiw them... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2385&page=2#post-92731 Thu, 29 Nov 2012 11:00:24 +0000 steveo 92731@http://citycyclingedinburgh.info/bbpress/ <p>Dave this is the slightly better regulator I found from some intensive google work earlier in the year </p> <p><a href="http://yacf.co.uk/forum/index.php?topic=6672.msg116111#msg116111" rel="nofollow">http://yacf.co.uk/forum/index.php?topic=6672.msg116111#msg116111</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2385&page=2#post-92727 Thu, 29 Nov 2012 10:52:38 +0000 DaveC 92727@http://citycyclingedinburgh.info/bbpress/ <p>Saw this tweeted today.

Its nominally a sine wave but in reality its all over the shop. Nominal 6v at 500ma but voltage can rise to &gt;100v if unloaded, you realllly want some circuitry in there. </p> <p>Best bet I think is either the 4aa nicad I mentioned last year or a fairly chunky capacitor and a 5v regulator of some description preferably one with a fairly high v-max. A LM517 might do but you'd need to keep it loaded to keep the voltage down. </p> <p>I've got some better links for diy projects in the office I'll post them in the morning. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2385&page=2#post-92692 Wed, 28 Nov 2012 22:27:45 +0000 DaveC 92692@http://citycyclingedinburgh.info/bbpress/ <p>Let us know how you get on Steveo, though looking at the pics on the Biologic website there is no port for charging, which means cutting the case. Though at $55 (incl SII silicon insert) for the case they are not so expensive. I just need an simple rectifier and regulator circuit, which can be easily made from Maplins. Just mount on the underside of the handlebars, and plug into the two spare (rear light) leads which come out of my B&amp;M light.</p> <p>Do you know what the output from the Shimano dynamo is? Is it a sinewave or just pulsed DC 6V&gt; If sinewave is 6V pk to pk or RMS?</p> <p>Dave C </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2385&page=2#post-92498 Wed, 28 Nov 2012 10:22:45 +0000 steveo 92498@http://citycyclingedinburgh.info/bbpress/ <p>There is a guy selling a few biologic chargers on ebay for £20 at the moment, still trying to decide to get one or not... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2385&page=2#post-92486 Wed, 28 Nov 2012 08:05:50 +0000 Bigjack 92486@http://citycyclingedinburgh.info/bbpress/ <p>I got the Nokia DC14 which I plug into the hub dynamo (although it comes with a bottle dynamo).Although it comes with the standard Nokia micro plug you can get suitable adaptors from Amazon or ebay for any other kind of plug. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=2385&page=2#post-92482 Wed, 28 Nov 2012 00:44:14 +0000 kaputnik 92482@http://citycyclingedinburgh.info/bbpress/ <p>The latest <a href="http://www.bumm.de/produkte/dynamo-scheinwerfer/lumotec-iq2-luxos.html">Luxos IQ2</a> light from BuM has a USB charging port included.
