What's the project?

We are going to build a Mate Light-inspired display at Noisebridge. Our goal is to have this completed for MakerFaire for use there. Then the display will be permanently installed within Noisebridge.

Idea is based on the c-base matelight display shown at the 32C3 and the 2015 Chaos Communication Camp. Our code that drives many LED strips from a Raspberry Pi is on Flaschen-Taschen github.

Flaschen Taschen is planned to be 9' 9" wide 7' 7" tall (about 3m x 2.3m) and host 1575 lights. See the drawings at the bottom of this page for the current design information.

We'd like your help with this. Very soon we will be scheduling build nights, build/drink ups, and drink ups. So please keep in touch.

In this blog post you see some work-in-progress video.

Drink Ups

This project requires a lot of bottles, so we'll want to setup a bunch of "Shut Up, Drink Up, Hack Up" events at Noisebridge.

Requirement for Bottles

12 oz is the right size
  • Approximately 12 oz (which is the average beer/soda bottle size)
  • Clear glass only
  • Rinsed out with water

Bottles are known to work

Check out this amazing matrix of beverages and sellers!

  • Most glass soda bottles with flat sides, such as Jarritos.
  • Corona
  • Some nicer ciders like Crispin
  • Club Mate

Where to buy in bulk

List out where we could buy some of these in bulk for the drink ups

Costco should have Corona for <= $1 a bottle.

Server

There is a server running on flaschen-taschen.local that supports three protocols:

  • FlaschenTaschen framebuffer protocol: receives UDP packet with a PPM image on port 1337
  • Runs http://openpixelcontrol.org/ server on standard port 7890
  • Provides pixel pusher compatible control. Can be easily be controlled using processing (use the in-app browser to get the third-party lib for PixelPusher and play with the examples).

The native protocol is particularly simple: for instance, try the following all in the comfort of you shell (in bash, to be precise, that conveniently provides the /dev/udp pseudo-path):

 bash$ jpegtopnm myimage.jpg | pnmscale -xysize 20 20 > /dev/udp/flaschen-taschen.local/1337

There are utilities in the repository to send arbitrary images (including animated gifs) or even videos. It is also extremely simple to write your own client in any language that supports networking (See protocols section in documentation).
