My new countersinking technique is unstoppable.
Of course, a whole bunch more to do, but it goes.
Brightness levels are optimal.
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… Read More »A easier and more reliable way to join 144 LED per metre strips – sewing
It’s good data. There’s lots of it. I just need to work out what to do with it…
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… Read More »No Mitochondrion Mark 5 for Kiwiburn… but something else instead
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… Read More »Mitochondrion Mark 5.0.1 progress: almost enough LEDs
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… Read More »Testing level shifters for running Adafruit NeoPixel strips from a 3.3 Volt Teensy
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 for the NeoPixel LED strips.
Why do this? Before making the next Mitochondrion, it was time to learn some new technologies.
The Mitochondrion Mark 4 (my glowstaff) is not too bad – 88 LEDs controlled by an Arduino Nano. However, it might be pretty but it isn’t responsive or interactive. It just splatters photons everywhere, generating randomly-chosen patterns.
I want more than just random brightly coloured lights. I want emotion, narrative depth, and engagement. That requires a far gruntier microcontroller than an 8-bit Arduino. Something like a Teensy 3.0 – ARM Cortex, 32 bit, about fifty times faster, lots more memory, and only 18 mm wide. And LED technology marches ever on, with Adafruit’s Neopixel strips being a big step up. And all of that is pushing me to use lithium batteries, even if they take more looking after than NiMH.
Thus it’s time to step up my technological game for the Mitochondrion Mark 5. The Hat seemed like a simple project that I could use for learning these new technologies – how to use them and what to use them for. Now that the Hat is working, I’m glad I took this step, because trying to get all this to work for the first time in the Mark 5 would be a bugger.Read More »180 LED Hat for Kiwiburn
