== Description ==
DIY stage LED for the lightshow of the [https://fixme.ch/node/224 concert of the FIXME metal band], the Tendinites!

== Goal ==
* Cool light effects
* Synced precisely to the music (not auto generated)

== Hardware ==
* Tube: 2x 1 meters d:12mm aluminum with a PVC 10cm tube to join two tubes together
* Tube foot: table leg with 3d printed inserts for the 12mm tube
* Tube holder: 6x 3D printed. A velcro is taped between the tube holder and the led profile for easy removal.
* Led profile: 6x 0.5m angle diffuser
* Led: 2x 1.5m 12v WS2814WW (individually addressed (by group of 3) 60led/ strip RGBW (warm white 3000k))
* PowerSupply: 100w 12v Meanwell
* Controller: Athom music esp32
* All of this x4 as I built 4 fixtures

== Software ==
Wled 0.14 installed on the 4 esp32 and around 30 presets created using the built-in effects. Using Art-net as an interface with a different universe for each of the units and set the channel to brightness + effect. On the computer, QLC+ 4.12 installed. I created a new Fixture using the editor with 2 channels (dimmer, effect), then created the same number of scenes as presets. Then I created virtual buttons calling each scene, linked with a MIDI trigger. In Ableton live, I created a set made out of all the songs in midi format. I created a new track that was firing MIDI notes using a midi loopback software to trigger QLC+. Finally, I used the markers in ableton with a novation midi keyboard to quickly navigate to the beginning of a song and trigger a stop at the end of it. The sound engineer manually triggered the button at the beginning of each song.

== V2 ideas ==
Questions:
* Is it ok to have 230v go to each light or is it better to have a large distribution box to convert to 12v and then use large 16AWG cable to distribute? Probably much heavier…
* LED: use RGB ultra bright (if only for lightshows?) What Digital 5v/12v/24v RGB(W) LED Strip to buy - quinled.info
* Controller: Use custom esp32 with ethernet ? Use PCB with Fuse + switch + level control + 5v
* Holder:
** use 1m angle diffuser? (less holder, tube 1.5m,...)
** Get rid of tube? -> how to hold the diffuser together?
** Replace the diffuser with own alu and own diffuser
* Base:
Foldable feet
Think about setting the stage with power and ethernet, and quick install of fixture (as in inspiration video)
Software:
Use geopixel, madmapper, or other DJ software for more control instead of QLC+

=== Bity ===

We are ~20 hackers from Bity and the crypto-currencies community around Switzerland to be willing to come. As you know last year we organised https://events.ccc.de/congress/2017/wiki/index.php/Assembly:Crypto_Currencies I emailed CCC tickets department to get vouchers, but they asked to contact a local hackerspace. So here we are. As you know most of us are attending usually via Fixme or Will's group. Now we are even more to participate and will need a total of approximately 20 vouchers. We will bring lot of activities around crypto.

We are also with people from Paralelni polis and might organise with them for the Assembly

== Description ==
* Networked satellite tracking basestation, opensource project: https://satnogs.org/

== Goal ==
* Operate a SatNOGS antenna at FIXME
* Build most of the parts using Fixme's equipment (PCB making station, 3D printer, laser cutter, etc)

== Components ==
* https://satnogs.org/documentation/hardware/
* You can print the components and put them in the box in the green shelf
** Settings: 0.25 layer height, bottom/top thinckness 1.0, infill 100%
* Feel free to advance the project, and add the part you're building on the wiki

=== Parts ===
* Rotator: https://wiki.satnogs.org/SatNOGS_Rotator_v3
