Have you been wanting to dip your toe into the world of programming but you’re not sure where to start? Need a gentle introduction that assumes no prior knowledge? I have a class for you.

This Saturday we’ll be teaching a class on programming NeoPixels with the Adafruit Flora microcontroller. I love programming things that blink because not only are you controlling something in the real world, but you can also instantly “see” what your code is doing. And NeoPixels are nice because there is no breadboarding. You just tie two components together with 3 wires, and off you go. You don’t even have to solder.

In the class on Saturday we will be teaching the basics of programming (what is a data type? how do loops work?, etc.) using several sample programs that you will learn to edit to change patterns. It’s a great way to get acquainted with what programming is like, and to learn some fundamentals. You can get tickets here.

And don’t worry, class will end before the World Cup begins, and you’re welcome to stay and watch the game on our big screen.

And if you do have experience programming, and would like to branch out into Arduino-based blinky things, we have a NeoPixel programming class for experienced coders on Sunday. Tickets are here.

Want to add blink to your wardrobe? Want to light up the night at Burning Man or the next NYC dance party? This intro class covers materials for illuminating your outfits. With a mixture of hands-on tutorials and demos we’ll teach you how to incorporate LEDs, NeoPixels, EL Wire, and fiber optic filament into your outfits.

This is an assembly-only class, no programming, but we will be providing some basic code to get you up and running. You are welcome to bring an outfit to add NeoPixels to, or we will provide a fabric swatch to practice on. Don’t forget your laptop! Get your tickets here.

Instructors for this class include team members responsible for our recent and on-going collaboration with the Brooklyn Ballet, adding blinky technology to the dancers’ costumes.

Felting Needles

felting needles


Resistor had it’s first crafting Make-Along recently. Our theme: Felting. We started with wool roving, which is wool that has been carded or combed in preparation for being spun. It looks a bit like cotton candy. Roving can be felted by agitating it, causing the individual fibers to knot together. One way to do this is to poke a bundle of roving repeatedly with a felting needle, which has tiny grooves that catch and pull at the fibers to tangle them. This is particularly effective for delicate work, and is a nice tool for creating small balls and creatures and for doing applique.

Another way to felt is to wet and rub the fibers. We made some felted soaps this way. We started with glycerin soap, wet it and wrapped roving around it, and then moistened it again with hot water to press the fibers onto the soap. After this the soap was dropped into a plastic bag and rubbed until frothy and matted. Then we rinsed them, and left them to dry. The result is a decorative, scrubby soap. Designs are created by felting onto the roving before wrapping it around the soap. Surprisingly the wetting and rubbing procedure doesn’t distort the design.

Felting can also be a creative way to repair clothes. One of our felters at the Make-Along brought a sweater with a hole in it, and felted on a flower on as a patch.

At our next Make-Along we’ll be working with paper. We’ll have patterns, ideas, and some supplies, but you can also bring your own projects and supplies. Here’s a little inspiration.

Alarm clock wakeup

I’ve been wanting a sunrise lamp for a long time, but I’ve never found the perfect one. Having a free summer, and the knowledge that I would be starting my first full time job in many years in the fall motivated me to actually make something happen. I’m glad I had the whole summer because this project had several learning curves for me — it was my very first electronics project, my first chance to learn how to use a laser cutter, and my first foray back into programming in many years. It turned out to be a lot of fun, and I’m looking forward to doing more projects like this!
