[[File:Led_overview.jpg|350px]]

TkkrLab used the lights of OHM2013 on the following events :
* [http://2013.gogbot.nl‎ Gogbot Sept. 2013], Enschede
* [http://www.tecart.nl/ TEC ART Feb 2014], Roterdam
* [http://www.greenvibrations.nl/ Green vibrations hemelvaart 2014], Enschede

This lights exist of 
* LED strips / sleves
* Pixels
* Floodlights

All can be controlled by ethernet/dmx For more info see [https://ohm2013.org/wiki/Team:LOC/DMX_lighting OHM2013 site]

To connect all the lamps these are connected over ethernet UTP cables where [http://en.wikipedia.org/wiki/Art-Net Art-Net] packets (UDP in certain format) are send [http://www.artisticlicence.com/WebSiteMaster/User%20Guides/art-net.pdf 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[?]

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
* source code & pcb layout  [https://github.com/bobo1on1/loc_controller firmware controller])
* Sort -> for Pixies / O = Ledstrip
* 12V / 5V
response to universe 0 (broadcast) and their own ip number

== LED strips ==
* 5m 150 LEDS
* 5V

==Sleeve==
[[File:LED_Sleeve.jpg|250px]]

* 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 ==
[[File:One pixel.jpg|150px]]

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

== Floodlights==
[[File:LED_floodlights.JPG|250px]]

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

==Floodlights Controller==

''' 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

[[User:Onedutch|OneDutchBrother]] has bought 2 controllers and several Floodlights, and is now experienced using the equipment. (Without Blow Up)

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.
