LED Grid: RGB, The Evolution

This started with wanting a new outfit for EMFcamp. EMFcamp ended up being cancelled this year, but the project had begun (in earnest at SciHackDay), so I had to finish it (at campGNDd). At least I'll be real prepared for 2022.

Once upon a time I made a 7x7 blue LED matrix grid top, with LED beads and conductive thread. (I've since misplaced it. *sad face*) I wanted something similar, but green, and that could survive hanging out in a field for several days. I've learnt a few things in the last *checks* ten years, so wanted to upgrade things a bit.

First things first; RGB LEDs. Single colour LEDs have their place, but the limitations are rather absolute. NeoPixel Mini Buttons are the smallest breakouts available. They come in five packs (Adafruit / Pimoroni), and in fifty packs (Adafruit / Pimoroni). You simply snap them apart, and chain them up, to use. The solder pads are on the back, the usual 5V in/out, GND in/out, Data in/out.

Details, glorious details )

And here is it worn, and on. Again you can see the grid conforming to my body rather than constricting it. You can also see that I only have it attached at the top two corners. The grid is so flexible that its own weight (91g) is pulling it down in the middle. (Easily corrected by attaching more points of the top tape to the outfit.)

So it's flexible, it's versatile, but how durable is it? This is the first version, so we'll have to wait and see.

Sugru'd earphones and footwear

I've had more adventures in Sugru! Some good, some not so good. You can see the previous post here.

I bought some new packs, of black and white (which I haven't used yet, tut), and they sent me a nice little booklet full of helpful information. It has a chart of what colours to mix in what proportions to give you other colours! It has a section on texturing for a better grip, and they tell you that soapy-water is a release agent!

Onwards to more Sugru adventures!

Sugru'd video goggles

Now I'm sure you've already heard of Sugru. I got a pack at MakerFaire, and only just around to using some. Inside the big pack you get twelve little packs in different colours.

Pics! )

But, yes, Sugru, teh awesome. Ten more sachets to play with :D (Hopefully before it expires.) Have you used Sugru? What did you use it for?

*edit* Having looked through the Sugru gallery I now intend to fix all my half-broken pairs of earphones!
