My main battery has a pretty nice cradle, and works well, but it isn\u2019t enough power. I like physical switches, and a second battery has to have its own 7.4v -&gt; 5v DC -DC converter, and its own switch. This works..but means more holes, and I have to flip two switches on and two switches off. And I have to take the wheel apart in two locations to charge the battery. I guess 4 batteries spread throughout the wheel might be best\u2026and I wish I had a clever way to have them all output 5v, and easily be chargeable all at the same time. That would be awesome.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" title=\"IMG_6109.JPG\" src=\"http:\/\/www.corbinstreehouse.com\/blog\/wp-content\/uploads\/2016\/04\/IMG_61091.jpg\" alt=\"IMG 6109\" width=\"800\" height=\"600\" border=\"0\" \/>\\<\/p>\n<p>Epoxy \u2014 don\u2019t forget to heat up the room. Covering with tape still works well, but is a pain. Wiping with acetone makes it easy to clean off tape residue.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" title=\"IMG_6117.JPG\" src=\"http:\/\/www.corbinstreehouse.com\/blog\/wp-content\/uploads\/2016\/04\/IMG_6117.jpg\" alt=\"IMG 6117\" width=\"800\" height=\"600\" border=\"0\" \/><\/p>\n<p>\u00a0<\/p>\n<p>I discovered a problem when I ran certain patterns. The LEDs furthest from the chip (the two left pieces) would get some wrong data. The only way I could fix this was to slow down the clock speed. 24Mhz doesn\u2019t work at all; 12Mhz works well for a certain amount of LEDs, and I have to run it at 8-10Mhz. \u00a0At first I thought I had a bad LED and was going to have to crack apart the epoxy, but a bunch of careful testing made me realize it was the really long length of strips (804 LEDs is quite a bit).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" title=\"IMG_6243.JPG\" src=\"http:\/\/www.corbinstreehouse.com\/blog\/wp-content\/uploads\/2016\/04\/IMG_6243.jpg\" alt=\"IMG 6243\" width=\"800\" height=\"600\" border=\"0\" \/><\/p>\n<p>Still working on it&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Okay\u2026the wheel is coming along!
