Burning Seed 2015

I didn’t think this through

I learnt some very insightful things last weekend, whilst attending Burning Seed 2015. This was my very 1st “burn” ever!

Above is an awesome still shot of me wearing the Wow Suit and the V4 LED Mask Hot glue is not the best thing to use when making complicated electronics used in the Australian outback! Who would have thought ? Whilst none of my creations suffered at all, it was the very 1st thought that ran through my head as i opened my car at 5pm after a 30 sunny day. I met some very interesting people, one awesome gent told me about E6000 which is a solvent glue that solidifies hard permanently. I will be trilling this for my future wearable projects

The best way to test your power usage is to run it in a real world scenario. The wow suit lasts for exactly 6 hours on 4 x 10ah packs. The 5th power pack, which i use to power the RPiA+, was 70% full after the 2nd night of use. I managed to to swap over the 4 LED power packs at about midnight with the help of my bestest friends.

People LOVE to hug at festivals. Why didn’t i think about this one? about every 3rd person who came up to to check out the suit wanted to hug me. “I want a light hug” …. “bright hug me”….”oh my god woooow…can I please hug you”. This is totally awesome, and an absolutely acceptable way to go WOW in my books! No one was denied a hug…well almost no one, there was that one really smelly naked hippy! The suit stood up to the challenge and didn’t break.

Test your code over and over! Whilst standing in front of a small crowd of people, suddenly my whole right side went dark….i immediately freaked out…and then 5 seconds later immediately got a wave of relief when I realised I coded the frame to buffer incorrectly whilst shifting pixels! I then stopped looking down at myself in fear of seeing this dreaded bug every 10 minutes.

If you plan to wear almost 2000 very bright animated LEDs on your body, PLAN your evening accordingly. I found myself unable to enter any small covered areas in fear of freaking out the crowd around me. I also stood helpless as hundreds of very munted people drooled over the animations! This i didn’t mind so much, i just wasn’t prepared for it.

Deep Sea LED Creatures


With thanks to Aerie from Kamp Kraken, who put together the creatures bodies, i was able to make these awesome looking bases:


No, get your mind out of the gutter :) its not what you think:

The will be decorated and hug on a big hoop. I really hope everyone at Burning Seed likes these!

LED Mask – V4

I started work on a new version of the LED mask. I recently found a less creepy plastic face mask, and decided to work my magic on it:

First thing to do is to map out the LED arrangements. This is key to how each strip is connected and how the software drives the LEDs. You can see the strip placement markers and the direction of data below.

It has a kinder, more neutral appearance…

Next I cut up the LED strips and prep them each for placement on the mask. I usually mark out the required length of connector wires on the mask and cut them up, prep them with solder and markers

Finally I connect each strip together in the order assigned in step 1, and the stick the strips to the mask:

And here is a test animation of the new mask in action:

This version uses the NodeMCU V1 module. Great little piece of hardware!

A couple of new pieces

First off we have the lovely pink lady from many a Coco Poco Loco party:

wpid-20150915_114513.jpg This is in fact a very silly looking fiber glass model of a naked lady. It has a base with a normal bulb inside.

The outside is covered in small glass pieces and the inside is covered in jagged fiber glass that cut my arm up pretty badly

I was asked to work my magic and here it is:

I put a strip in the head, onto the bust, all the way up the spine and along the lower parts of the front facing legs. The whole thing uses about 68 LEDs from a WS2812b strip. I used a NodeMCU for this, just for shits and giggles and to see if i could get it to drive WS2812B strips. I used THIS modified NeoPixel driver with the NodeMCU module running at 160Mhz. Note you must use the UART driven library on Pin 4. Here is another example:

Next up is Jords Disco Shoulder Pads

I used a Arduino Nano for this along side a WS2812B LED Strip. The results is hillarious:

My best piece to date in my opinion:

The LED Sphere

I have had this idea in my head ever since i saw these cheap lighting fixtures at Ikea:

These comprise of 2 outdoor lights. the bottoms are hollowed out and fixed together using some screws.

Each half has 182 LEDs arranged in 13 x 14pixel strips.  You end up with a 28 x 13 pixel grid to work with, and for magic to begin.

The sphere is controlled using a NodeMcu clone that runs an ESP8266 core. It easily accepts Arduino code via the latest Arduino IDE so porting my code was relatively simple. The only change required was the FastLED library which isn’t yet supported on the ESP8266 core. The APA102 LED strips can be driven using standard SPI so rewriting the driver was pretty easy. The SPI library for the NodeMcu is even better than the arduino as it has frame based transmition where you can just shoot out a huge buffer of bytes at one go, instead of byte by byte. The performance increase is massive.

Look at these Pods!!

I added a capacitor inside each pod to help with the power issues I was having! Look at these Glorious colors! They are not very neatly set up at present, as I’m still testing out the basic driver system.

Power Modules for Burning Seed have arrived


15 x 10Ah @ 5V Battery Modules

All the Battery modules have arrived and all work! Yei!!! I have planned to run the Wow Suit for 3 nights. The suit requires 4 x Modules for the LEDs and 1 module for the Controller. I have recently migrated all my code and control software to a Raspberry Pi Model A+. Im sing the “mraa” NodeJS module to drive the suit via SPI. The A+ only requires 5V!!! Another YEI!
