LaserBoy !!! / Compiling Laserboy on OSX 10.9

« on: November 21, 2013, 09:46:11 am »

Hi James,

  I followed the instructions for installing on osx 10.8 but the compilation fails with this error.

Code: [Select]

In file included from ./LaserBoy_space.hpp:34:
./LaserBoy_frame_set.hpp:259:38: error: parameter of overloaded 'operator++' cannot have a default argument
    LaserBoy_frame& operator ++ (int = 0) //post
                                     ^
./LaserBoy_frame_set.hpp:272:38: error: parameter of overloaded 'operator--' cannot have a default argument
    LaserBoy_frame& operator -- (int = 0) // post

Any ideas?

DACs / Problems calibrating a new laserboy DAC

« on: November 21, 2013, 09:43:02 am »

Hi James, and other laserians.

I'm having some issues calibrating this dac.  After your help figuring it was one of the LM072 chips I replaced those with an LM358 (another dual op-amp) and tried to do calibration on it.  At least until I have time to go pick up the new chips.

I've managed to zero all the colour channels but when I check the X or Y I get +8.5V and -8.5V and nothing I do with the voltage offset seems to do anything.
This is still without a test signal from the soundcard.  I'm using the pins right on the IC's to check, so pin 1 for the xy and intensity and pin 7 for the color channels. Although the color and intensity channels testing on the jumpers yields the same numbers.

Any idea what's going on or where I should probe to see what's happening? It's not the actual chips as the color channels are behaving normally and swapping them around doesn't seem to change this annomaly.
