Here's what the finished setup looked like for some LED fun I put together

Here’s what the finished setup looked like for some LED fun I put together for a 3.5 hour night “glow” hike. It turned out great. The 28 hikers all had multiple glow sticks in all varieties, but this was a total hit.

LPD8806 strip (1m long, 32 pixels), controller was a Teensy 3.0, and power from a cell phone recharger battery. The strip was slipped into one of those 1" cable organizer tubes and that attached to the backpack with a few Velcro straps. Controller and battery tucked perfectly into a little pocket on top of backpack. I had the master brightness turned down to 40 but it was still really bright out on the dark trails!

Code was a modified DemoReel100 sketch and a few more added patterns that it randomly picked between. I made a few patterns “rare” so they didn’t come up all the time, and one of the calmer patterns sort of the default that ran about 60% of the time.

Ooh!, I was looking for something like this to build. Where did you get the wire loom? It diffuses the light really well!

Nice! I picked up some wire loom from Ikea, been meaning to try it out. Thanks for the nudge. :slight_smile:

@Adam_Wright ​ Found it at Home Depot in electrical area. It works very nicely.

@marmil Thanks! I would have guessed there, but wanted to make sure before I made the trip. Prices on Amazon were outrageous

It also looks a LOT like pool tubing (which I have used in addition to split loom).

I guess the advantage of using pool tubing would be that it’s more sealed/protective against the elements since it’s not slit open. @Andrew_Tuline , were you able to buy the pool tubing by the foot or in smallish lengths?

I bought it in one long tube (whatever was available at Canadian Tire) and then cut it to 1M lengths over time.

Here’s a video giving an idea of what it looked like in action. Video is running 4x speed so it was actually more calm then this for the people hiking along side. (But 4x speed does look cool too!)
