Teensy Project Roundup
What can you use a Teensy for? A surprising number of things!
In case you weren't aware, SparkFun is now the sole manufacturer and sales channel partner for PJRC's beloved Teensy® line. We've been really blown away by the community's support and enthusiasm for our favorite small microcontroller (not that we're biased or anything). We've also seen a bunch of really creative projects around the web that are helping us understand what customers are using Teensy for, but also what Teensy is capable of. We thought we'd highlight a few of our favorites on today's blog.
Loom Light
by Christine Sunu
Loom Light is a "Teensy driven LED system lights up the shafts of a 16 shaft table loom to make weaving easier. It reads .wif files from an SD card and has little flippers on each side that let you advance the pattern." There is a cool video demo at the BSKY link below explaining how the system works. "Clicking the little buttons causes the pick to advance. Blues are levers that should be flipped, whites are ones that shouldn't, and reds are ones that were previously down but now should be up. The color shifts slightly on each pick. This helps a lot in keeping track of the pattern."
A full list of code, materials, and wiring can be found at the GitHub link below. What a cool application for the Teensy 4.1!

2-key keyboard for a rhythm game.
By Adrian
This is a simple, if not really satisfyingly-professional looking project that came about from someone wanting to make a light-hearted surprise gift for their friend, who is apparently an avid fan of the rhythm game OSU!. Little projects like this are a great way for beginners to learn some of the basics around electronics and design! The result: a simple-yet-cute little two-key keyboard with a Teensy housed underneath.

One Hacker Band uses Teensy to make musical instruments play themselves!
By Aaron Todd
One Hacker Band (aka Aaron Todd), is a band that utilizes Teensys to control instruments via MIDI. For instance, a keyboard playing Van Halen on it's own... (RIP Eddie) say less! This rad project utilizes a bunch of servos that pull down on each individual key, getting input from a Teensy which is taking in MIDI and interpreting it into the exact servo locations.
Aaron does more than just keyboards though. Check out this fully-automated band covering Nirvana!
