As has been well-documented, I like playing with LEDs. My art project of the past year has involved LEDs attached to people doing their thing and being captured in a long exposure. It’s been fun.<\/p>\n

Since then, I slowed on the shoots while trying to think of something else to do. During this time,\u00a0I was sent links to other long exposure projects new and old. One project I liked is the light bar that originally was a KickStarter project called the PixelStick<\/a>. It’s very\u00a0cool but at $349 USD<\/a> out of my price range. If it’s not out of yours, buy it!<\/p>\n

I digress. I decided to look at the project from the perspective of what would I need to make one of those light bars and would I need to buy anything to do it?<\/em> I’m heading to Maker Faire Ottawa<\/a> in a few days and wanted a new project to show at my table.<\/p>\n

I looked around my workspace for applicable components. A slip ring<\/a>. I’d bought a pair for a project that went on hold and shows no signs of returning. The slip ring would allow me to spin a bar while powering and controlling the LEDs from another source. An Arduino UNO. I did break down and buy an Arduino Pro Mini for the size. If you don’t want to, don’t. I’m a fan of making do<\/em> most times but I wanted something cleaner. LEDs. I had some leftover cast-offs from my last Infinity Mirror workshop<\/a> so I could rescue them for this project. I used leftover cuts from my LED clock build<\/a> because I wanted something moderately nice and didn’t want to spend money on new cuts. I also had a 3.7V LiPo battery with a charger. So mobile power was a go! Did you know you could power an Arduino AND a strip of LEDs with a 3.7V battery? Now you do!<\/p>\n

The last thing I’d need is a handle. Turns out, when you own a 3D printer and have a little experience modelling stuff, you can sort yourself out.<\/p>\n
