Hi all,
I am looking at making an LED project using the Teensy 3.1:
I want to connect two Teensies to two 2m lengths of this and line the insides of two separate 1m lengths of clear plastic tubing so that I can make a pair of 'programmable LED Staffs' to twirl / juggle with (i.e., Each 1m staff will have 2m of LED strips - the lights will thus be visible on both sides). My inspiration comes from MortonKopf among others, who has an AWESOME and inspiring blog about light painting and other LED projects using the Teensy, here.
I am wondering, firstly:
- Are there any other 'better' light strips I could use - eg with more pixel density?.
I am wondering what kind of light arrays the more expensive manufactured POV toys use (like the $1500 'visual poi' here - video here , and the $400 "future poi" here with corresponding video here).
NB: I looked at a guy's "future poi" last week in a park and counted the lights - there were about 40 (x2 strips) on each POI, which were only about a foot long. They looked incredible. Maybe they were not WS2812Bs, maybe they were smaller lights like 3528 SMDs? (I knew absolutely nothing last week, so if I see him this week I will take pics / vid and get a closer look and post back to this thread).
- I also stumbled across this impressive project, but have no idea what light array he is using... Maybe I am aiming too high for a first project, I don't know... I just can't see how manufacturers are selling this simple technology for $1500!!! (what does it do that a Teensy 3.1 / Arduino can't do to some RGB strips, provided they have the same pixel density)?
Second Question: - what it the best way to connect the Teensy to the Strips & Battery source, in the most secure way so that it can withstand both inertia of being spun around, thrown, and caught, but also occasionally (accidentally) dropped? . Naturally simple soldering will not withstand such punishment...
Would something like this work?
- I am a bit of a newbie to all things electronic, and am not exactly sure from the Teensy pics where I am supposed to connect it to the power supply or if cables like these would be a feasible solution (from pics, the teensy to me just looks like a circuit board with no connectors, suggesting to me that it can only be soldered to wires directly. Am I wrong?).
- I fear that merely soldering all wires might not be strong enough, hence my idea of these little cables.
I was thinking of using a 3.7v rechargeable battery for both staffs, or something slightly lower-powered, but USB rechargeable.
Thanks in advance, Teensy pals!
