- A tracer per etherdream/laser that take current client point list, correct geometry, recompute in etherdreams coordinates, send it to its controller,... and report etherdream status to the manager.
- A manager that talk to all tracers (which client number point lists to draw, new geometry correction,...), handle the webui functions, OSC commands,...
- Up to ten clients, that simultaneously send one point list per laser.
You run and write your clients in any redis capable programming langage (50+ : https://redis.io/clients).
Needs at least : an etherdream DAC connected to an ILDA laser, RJ 45 IP network (gigabits only !! no wifi, 100 mpbs doesn't work well with several lasers)
- A compiled version for os x and linux of nannou.org etherdream+laser emulator is included. For more informations, like license see https://github.com/nannou-org/ether-dream
We use static network configuration. Our Etherdreams controllers have static IPs defined in their SDcard from 192.168.1.1 to 192.168.1.9. Because wifi will always finally sucks for many reasons, our computers (laser server and clients) are *gigabits wired connected* with 192.168.1.10 and after. Don't trust end user gear marketing on wifi, we have a big gigabits switch for laser only stuff. We provide Internet through wifi on different network like 192.168.2.x
A dedicated computer to act as "laser server" usually depends on how many lasers you want to control and your main computer load. If you seen flickering with small point lists, try the dedicated computer option and/or stop process interfering like redis monitoring,...
This program suppose that the ether dream is configured in a certain way especially for its IP address. For ether dream 1 : write an autoplay.txt file inside an SD Card within the ether dream DAC, with the following lines you can adjust i.e for pps or fps. Yes, there is a builtin DHCP client in the ether dream DAC but if you run multiple lasers, having a fixed dedicated network makes you focus on laser stuff.
/net/ipaddr 192.168.1.3
/net/netmask 255.255.255.0
/net/gateway 192.168.1.1
/ilda/pps 25000
/ilda/fps 25
About hardware setup, especially if you have several lasers : ILDA cables are insanely expensive. You may consider the Power Over Ethernet 'POE' option. Buy a very small ILDA cable, a POE splitter and connect everything to the ether dream fixed near your laser. You can have then a simple and very long network cable and use a Power Over Ethernet injector or switch closed to the driving computer. Beware some vendors use 24V POE Injector : POE injectors and splitters must match.
