Two very dear friends decided to have their wedding at the same place they met: AfrikaBurn.
To do this, they would have to bring two families from three countries together in the Tankwa desert.
Instead of a wedding cake, they came to me to help create a chariot for the wedding.
This led to a year long process of design, build and burn.

All work is mine, unless otherwise noted.
Skills utilised in the project:
Our initial meeting led to the following wishlist:
The classic pumpkin towed by a mouse was chosen.
We wanted the bride to be presented from a blooming flower, so the protea was chosen as inspiration.
Afrikaburn can be quite disorienting at night. We needed a beacon and a home base where you can find your tribe, even from the other side of the playa.
We wanted the recreate the feeling of sitting around a bonfire. We wanted it to be an initmate enclosed space, whilst still being open to the outside world.
The majority of the materials used in building the camp and everything around the wedding was recycled materials, and much time was spent sourcing materials. Everything short of the electronics were recovered materials.
The playa may seem flat, but sandy, dry river beds crossed the playa in various places. The vehicle needed to be able to deal with these conditions at night whilst carrying up to 15 people.
We had a hard time choosing between a vehicle and burning an artwork, so why not both?
An initial model was drawn up using fusion 360 to play around with concepts.
After the initial design, I laser cut the pieces out of some modelling board to create a physical scale model.
The scale model was used during the entire build phase as reference, and travelled with us to the desert. It eventually met the same fate as its bigger brother.
The chariot required the following in terms of electronics:
Control over 40 meters of LED strips, divided into 8 lines. Each of the lines needed to be individually addressable and each colour needed to be pwm controlled.
A sound system consisting of an amplifier, subwoofer and four 6x9 speakers.
A supply of power that can keep both the sound and lights running for at least 12 hours, along with a charge display.
Pictured here is the circuit to control the LED outputs. Not shown are the input controls, sound system and power supply.
First step of the build process was cutting the pieces. The groom and I worked our way through almost 100 pieces, countless blades, and two jigsaws.
The platform on the trailer was built using old pallets, which also needed to be cut and adjusted to be fit for purpose.
The electronics were driven by an Arduino mega, with custom designed boards that were daisy chained to control the LEDs.
The boards consisted of a shift register and a transistor to control every color. Each board were set up to control two strips, and pass the signal on to the next board.
A display provided the controller with system information, and modes were selectable using a potentiometer.
The code was built to control the LEDs.
The scripts included 10 modes to select from.
There was some base work done to include an FFT mode so the lights react to music, but we ran out of time before that was finalised.
Code on GithubFour of us arrived in Tankwa a week before the event to put everything together.
The first step was putting the base of the trailer together. The base was constructed using pallets and reclaimed floorboards.
After the base was laid down the fins needed to be mounted. Work carried on until late every night.
Hydration in the desert is of extreme importance. All supplies had to be brought along. A supply run would cost hours of driving, and we could not afford that. If we did not have it there, we had to make do with what we had, which meant that at a point we had to make drill bits, as we did not have one long enough to get through the base.
We cut holes in some of the fins with the goal of reducing the weight, as we had about half a ton of wood to mount.

Here Grizzly is hooked up for the first time. This was not an excuse to cruise the desert and drink beer, but rather cardinally important stability tests.
A view of the electronics and sound system mounted.
We had to pivot away from the centrally mounted sound system, as the rules require sound
systems to be directional.
Here the petals are mounted, and the Grizzly had been converted into a mouse. The Grizzly design was made up on the fly using some aluminium flatbar and stretch material.
Mice need cats to chase them, so we made one of those as well. Bikes are unfortunately not very practical with 10kph speed limits, and we decided to park it after a very out of breath ranger eventually caught up with us and threatened driving privilege suspension.
