OHM LEDS tijdens Green Vibrations

Led overview.jpg

TkkrLab used the lights of OHM2013 on the following events :

This lights exist of

  • LED strips / sleves
  • Pixels
  • Floodlights

All can be controlled by ethernet/dmx For more info see OHM2013 site

To connect all the lamps these are connected over ethernet UTP cables where Art-Net packets (UDP in certain format) are send specification.

The UTP cables are connected to a loc_controller, that controls the LED strips.

You need a dhcp server in the network to give all the LOC_controllers a ip, tip of OHM LOC Team was to use the isc dhcp server[?]

Hardware

LOC_Controller

These controllers are specialy developed for OHM2013. They connect directly with ethernet and the LED strip of pixies.

There are 2 jumpers on the controller, be sure to have them righ or you might blow something up

response to universe 0 (broadcast) and their own ip number

LED strips

  • 5m 150 LEDS
  • 5V

Sleeve

LED Sleeve.jpg

  • the above LED strip wound on a PVC tube
  • with power suply so you can connect this to 220V
  • with loc_controller with ethernet cable so you can connect it directly to a switch

Pixels

One pixel.jpg

  • 12V - 2,64A
  • 50 pixels on one strip
  • can be controlled with a Loc_controller

Floodlights

Specs: 12V powered 10W 5m cable 4 pin connector for +12V, R, G and B. Roughly 300mA per channel.

IF YOU CONNECT THESE TO THE POWER BE SURE THAT BLACK/GND IS TO CENTER AND THE YELLOW/ +12V TO THE EDGE. FAILING TO DO SO BLOW UP THE DMX CONTROLLER!!!!

Control of these are a bit different : Converter ethernet --> DMX =UTPcable=DMX512 controller--> Lights Sourcecode, pcb layout on http://ohm.sa007.nl/ Remark of SA007 : het optocoupler deel is geupgrade van deze schema 's en de output connectors zitten 180 graden gedraaid


  • DMX input
  • 12V powered (compatible with ATX 1.x P4 connector)
  • use a atmega169
  • 100 Watt light
  • 10x8cm, can control 10 lamps, isolated dmx bus, with 9 bit dipswitch
  • max 1A PWM per channel,so max 30A on the whole board

OneDutchBrother has bought 2 controllers and several Floodlights, and is now experienced using the equipment. (Without Blow Up)

ETH0-Floodlight 05.jpgETH0-Floodlight 04.jpg Currently I use the wires without the use of the common ground on the DMX connector. So I only use DMX+ en DMX- wires.

One of the troubles I have is that not only the the ATX 1.x P4 connector needs 12 Volt. Also the wires 4 and 7 needs 12 Volt, I used the same 12 Volt as the connected ATX 1.x P4 connector. If the setup has multiple controller board you could end up with Ground Loops.

End Result : Setup :

  • Laptop met Freestyler op Windows O.s.
  • USB - > DMX kabel (ENTTEC OPEN DMX Controller inclusief XLR Female)
  • Showtec Microspot Led moving head (DMX address 31)
  • Zelfgemaakt XLR Male naar RJ45
  • ETH0 Floodlight controller board
  • 2 Floodlights (op de eerste en op de laatste poort)
  • 12 Volt uit een PC voeding op de Floodlight controller board (ON led brand continue groen)
  • Dipswitch 1 op de Floodlight controller board op 1 gezet

Software

First you need the set up a netwerk, use isc dhcp server.


With special software that send specific packets you can control the lights.

OHM software

TkkrLab software


code door Duality: (wat led patroontjes gemaakt door Duality zo als barpole random leds, random shifting leds)


  • Freestyler (settings for OHM led lamps follows later)

Not tested yet but might be userfull http://www.solderlab.de/index.php/software/glediator
