General Discussion / Getting to 64k speed in OSX on a macbook?
« on: January 23, 2017, 12:31:59 PM »
I built openlase for OSX and am using jackd/jackdmp from "".  the fastest rate I can start jackd is 48000Hz.  The jack documentation says it will only allow rates supported by the input and output devices. "Built in Microphone" and "Built In Output" are what are selected by default in the JackPilot GUI interface.  Any ideas on how I might modify this parameter?  I can use the jackd command to try to start the server with a different rate: "jackd -R -d coreaudio -r 60000" but this results in an error saying something like the device doesn't support that frequency  My galvos are rated to 60k, so I'd like to max them out and see if I can increase my refresh rate.

OK, it wasn't that hard.  So This assumes an install on Yosemite using edy555's homebrew openlase install:

To get it to install in Yosemite, use
Code: [Select]
brew install openlase instead of
Code: [Select]
brew install openlase --HEAD
OK now that you have openlase installed, a couple of modifications are needed for lasershark to build. 

first install libusb and pkg-config:
Code: [Select]
brew install libusb
brew install pkg-config

now open the MakeFile in lasershark_hostapp and add
Code: [Select]
-I /usr/local/include -I /usr/local/include/libusb-1.0after the first "$(CFLAGS)"

It should look like:
Code: [Select]
$(CC) $(CFLAGS) -I /usr/local/include -I /usr/local/include/libusb-1.0 -o lasershark_jack lasershark_jack.c lasershark_lib.c `$(PKG_CONFIG) --libs --cflags jack libusb-1.0`
then use "make" and it should work!  You can ignore the linux instruction about editing permissions in /etc/udev, this is not needed in OSX.

I fumbled around in dependency hell with ubuntu and Mint VMs for a few hours before trying the OSX route with homebrew.

OSX installed way easier than anything else I tried!  The last step is compiling lasershark for OSX.  Any tips?  right now it's stuck since it can't find jack/jack.h or libusb.h.  I installed JackPilot, so probably have the jack files somewhere...

If anyone has this working, please let us know how you did it!

General Discussion / lens needed for laser?
« on: May 20, 2015, 12:30:59 AM »
I got an RGB Laser from ebay, and it doesn't seem perfectly focused.  This is what it looks like when the red laser is shined at a wall:

This is my setup:

Is there some kind of lens I need to focus the beams?  If so, does anyone have suggestions of what to use or look for?


OpenLase Discussion / Re: Cheap Linux Box Recommendations?

Thanks!  I think the best route might be to not go crazy trying to get a small SBC, but to get a small form factor PC with a core i3 or better off ebay or craigslist for cheap.  it doesn't need to be low power and the size is not a big concern.

It looks like if you compile world war vi with OPENLASE=1, it hopefully does the simplification for you.  The guy has videos of his laser rig running a simplified version. 

Thanks for the perspective on the hardware!

The Intel Compute Stick looks promising.  Thoughts?

OpenLase Discussion / Cheap Linux Box Recommendations?
« on: May 11, 2015, 11:26:34 PM »
I'm looking for a recommendation for a cheap linux box that I can permanently install with my projector.  I want it to be capable of running some of the openlase games like world war vi, and a node server for input via the web.

Do any of you have any recommendations?  What kind of specs will be the important ones to look for?
