Above you see the finished installation, I'm currently updating the code for a better gaming experience.
In the V-Slot Belt & Pinion Example Build the spacers for the wheels are 5mm. This is actually to tight when your using a piece of extrusion like I do instead of a gantry plate. The spacer for the wheels should actually be 8mm so there is space for the motor mount plate.
I made use of laser-cut acrylic glass to make 'stands' for the small NeoPixel bars, the single Neopixel ball (shown below) and the 14 segment Alpha-Numeric LED backpacks to show the score.
Testing all LEDs with SPI and one of the Alpha-Numeric backpacks over i2c.
All wires to the control box! I use a 12V power supply from Mean Well to drive the steppers. I make use of a UBEC step down converter to get to 5V for the Arduino and NeoPixels and Numeric Backpack.
I decided to make the lid of the little 'black' box transparent so the players can 'see' how it works.

Build in 'Everything Else' published by Gerrald, Jun 2, 2016.
This build is to show what's possible as well with openBuilds! I use a single ArduinoMega and 5 separate stepper drivers (A4988). The LEDs are all NeoPixels. Collision 'detection' is all done within the code, so the endstops are only sensors I use in this build. I'm a self-employed video-artist and this is my first installation which just needs power and it runs (where I'm quite proud of). Normally my interactive installations take a long setup time, so this installation is a relief :)

Special Notes
Any questions to this build are welcome, I hope to find some time to update the parts list for this build in the near future.
Due to the long wires to the Stepper motors I got interference on my end-stop switches and SPI signal for the LEDs when there's no SPI signal or message send.
I got rid of the interference (electro magnetic field) by adding condensators on the endstop wires.

Reason for this Build
I walked around with this idea for quite a while, and I wanted to place the machine in my toilet (it became to big, so now it's finished it din't end up there).
I dropped the idea at a children's movie festival for their MediaLab, they liked it and funded the whole project. Now it's a rental for other festivals as well.Inspired by
