The Flying Carpet

While lying on damp, cold, and hard ground at Kiwiburn one night, we decided that festivals are more fun when dry, warm, soft, and fluffy. So we made a festival blanket that we named the Flying Carpet – fluff on the top, waterproof underneath, padding in the middle, and LED animations around the edge (Teensy, …

In short: the Mitochondrion looks as stunning as I hoped for about five years ago. My journey into the obsession of making LED staffs About five years ago, I stopped fire spinning and started building LED staffs. I wanted to have images hanging in space around me while I am spinning staff. Technology (and my …

A easier and more reliable way to join 144 LED per metre strips – sewing

  Posted in Uncategorized on

  by Jez

The 144 LED per metre LED strips are stunning. The LEDs are close enough that they blur into a single bar of light. Sadly, the LEDs are close enough that joining the strips is a nightmare. The pads are tiny, joints are sketchy, the LEDs too close together to get an iron in there, and …

No Mitochondrion Mark 5 for Kiwiburn… but something else instead

  Posted in Uncategorized on

Right then, after a fair amount of swearing, I made the decision that the Mitochondrion Mark 5.0 has some fatal design flaws and won’t be ready for Kiwiburn. Turns out the 144 LED per metre Neopixel strips are a bastard to join and connect to. There’s a variety of ways to do it, none of …

Yeah, this is going to be bright. That’s the test power board, the test centre board, and the test strip. The power board holds four 16340 Li-Ion cells and a 5 Volt, 4 Amp converter (and some other gubbins). There’ll be four of them, one for each strip. The centre board holds the Teensy, motion …

Mitochondrion Mark 5.0.1 progress: almost enough LEDs

  Posted in Uncategorized on

  by Jez

  ,

The answer to the question “how many LEDs?” is always “moar!”. However, I think this counts as “almost enough”: And you’ll note from the change in version number that the Mark 5.0 power design didn’t work out. The Mark 5.0.1 power design is underway. In short, while I could fit 18.2 mm diameter cells into …

Winter, therefore tidying up

Winter’s kicked in, so I’ve switched modes into finishing things off, tidying up, and getting generally tatted down and squared away. So, the Too Bright Hat needed a new cable. 3-pin mini-XLRs seem to be the right balance of durable, small, and able to handle 8 Amps, but finding connectors with decent cable clamps took …

Testing level shifters for running Adafruit NeoPixel strips from a 3.3 Volt Teensy

  Posted in Uncategorized on

If you’re running NeoPixel LED strips off a Teensy 3, maybe because you want to put 180 LEDs on a hat, then you need a level shifter. But which one? The NeoPixel data protocol is high speed and pretty harsh on timing requirements and I’ve had a bugger of a time getting reliable data from …

180 LED Hat for Kiwiburn

Here’s details on my Kiwiburn project – a hat with 180 LEDs, all individually controlled… but to be honest, this was my project for Circulation, back in November. Getting it built was easy, getting it to work took quite some time, but I learnt a great deal. So here’s my design for a portable driver …

Four thousand LEDs

This is possibly the most relaxed video I’ve ever put together. Squidsoup were kind enough to let me have a play with Volume 4,096 – a sculpture of four thousand LEDs, in a 16x16x16 cube that hangs in the foyer of the Royal Society of New Zealand. These patterns are all Perlin noise in HSV-space, …

Circulation is one of New Zealand’s finest little circus festivals.

Mitochondrion Mark 4 code is now running on the Mark 5 chip. Teensy 3.0 – an ARM Cortex M4 on an 18 mm wide board. Consider me pleased. Have yet to time the code, but should be faster. Much faster. Which is required, as it might be possible to replace the Mark 4’s 88 LEDs …

That tiny thing is a Teensy 3.0. ARM Cortex M4. It’s a serious step up in performance from the Arduino Nano that runs the Mark 4. Four times the program memory, eight times the variable memory, four times the clock speed and 32 bit not 8, so quite substantially more grunty. Which is somewhat handy, …
