|Use case #3||Description|
|Date and location||Aug 31st--Sep 1st, 2013 - Bratislava, Slovakia|
|Show type||Village fair|
|Lights||Front: 2 PAR64 1000W, 4 PAR56 300W
Back/effect: 4 GLP Volkslicht moving heads on the back truss, 2 Varytec Gigabars II on the back truss, 4 PAR56 with color gels on each side
|Details||The event was a two-day village fair in a part of Bratislava. There were various acts from Abba revival through folk dance groups.
We have put white lights on separate circuit due to last-minute and not tested code changes. We wanted to avoid blackout if there are any problems with QLC+. That way we could also adjust scenes between acts.
I could only preprogram general scenes, since I didn't know the acts before. Due to lack of time, the side PAR56's were not included in the scenes.
I created scenes for several colors and color chases for the moving heads, and for LED bars. For moving heads, I created a collection of EFX movements -- circles, left-right (pan) and up-down (tilt), and positions (forward, upstage left, downstage left, upstage center, downstage center, etc.) These were created at home by guessing the angles and manually computing the DMX values for pan and tilt. I adjusted the positions a bit when we put the light in place. For the movements I created 3 variations -- all lights follow the same path, every other goes in the opposite direction, and all lights are offset by 90 degrees from the previous. That made 9 EFXs altogether.
For LED bars, I created RGB scripts for basic colors, that for some colors would run upwards, and for other downwards, so I could run more of them at once (I learned this trick from friends).
Timing: I created several speed dials each with its own fader on LC2412:

|Use case #4 - BLEM||Description|
|Date and location||October 31st, 2013 - Stia (Arezzo), Italy|
|Show type||Club, custom stage for a live dj set|
The BLEM project has been created by BLAQ Crew for a dj-set night in a local club.
The team home-made a LED Matrix panel with 250 RGB WS2801 pixels, controlled by a Raspberry Pi via SPI interfaces.
The Raspberry Pi was running OLA and it was listening for ArtNet packets sent through an ethernet network.
QLC+ was used to control both DMX fixtures (through DMX-USB) and Jinx!, a LED matrix software, with one DMX universe each.
Jinx was controlled remotely (changing scenes, presets, strobe, dimmer) via ArtNet protocol.
Both DMX fixtures and LED matrix scenes were mapped to QLC+ functions/chasers and triggered live by MIDI inputs pads.
The projection mapping you see in videos are controlled independently by VDMX and MadMapper.

|Use case #5 - Light Play||Description|
|Date and location||May 15-17, 2015 - San Mateo Maker Faire|
|Show type||Light Play - Artistic installation|
|Software equipment||Macbook Pro with QLC+ 4.8.4. Tested on Mountain Lion and Mavericks|
Home made FTDI USB-RS485 adapter
The installation consists of 84 delta robots mounted in groups of 7 on custom fitted base assemblies.
Each robot has 3 RC servo motors driving 3 arms which converge at an RGB LED. A custom made PCB using the same chip as the Arduino receives the DMX data coming from a RS485 CAT5 cable and is implemented as a QLC+ 6-channel Fixture.
The project consists in a series of still scenes that trigger groups of robots (just even, or just odd, or all)
to assume a position and change a color. After creating several dozen of these scenes they have been added
to a chaser, which would cycle through the scenes at a consistent interval.
Additionally, there's a virtual console with buttons which would trigger several other movement presets, as well as light patterns. This allows to select different combinations of movement and light patterns on the fly.
