Laser Software / Arduino laser controller

DISCLAIMER: This is not for controlling the laser modulation or galvos!

I have written a little piece of code for an Arduino designed to read the current state of the SHUTTER and INTERLOCK.

The code does the following.

IF the SHUTTER signal is OPEN (+5v) AND the INTERLOCK is a COMPLETE CIRCUIT, only then will a relay close providing power to the laser(s). (after a 5 second delay)

If at any point either of these states changes (shutter closes or interlock is broken) the relay immediately opens (its default un-powered state) and the lasers power is interrupted.

If laser power is interrupted there is a 5 second delay before you can turn the power back and the interlock and shutter have to be in the proper states else you cant turn it back on.

The current state of the laser power is printed to serial if you want to monitor the state.

For safety the GALVO power should not be interrupted

The Arduino pins are as follows

ShutterSignal = The signal coming from the ILDA shutter signal. +5v = Shutter OPEN (this is an input pin for reading the shutter voltage)
ShutterPin = Pin used to control the relay state (Output pin for sending signal to the relay)
InterlockOut = set to +v5 to send a constant signal over the interlock loop (+5v output pin)
InterlockIn = Reads the signal from the interlock loop sent from the InterlockOut pin(input pin)

The interlockIn pin has a 10k resistor to ground so that if the circuit is broken there is no voltage float to worry about.

Please feel free to ask any question you may have or suggest any additions to the system.

 I am thinking about adding a few temperature sensors that would shut down the ENTIRE system on overheat of a component and wait until it was below a certain threshold before allowing the system to start back up.

Code can be found here

NOTE: This sketch assumes that the the relay required a LOW signal to turn on. This can be edited in the #define section

Construction / Boxed up my projector.

I have put together my 1 watt RGB analog projector and its all neatly tucked inside an enclosure I scavenged from a 1000 watt sodium light ballast.

DACs / CMEDIA Win 10 driver
« on: November 12, 2018, 09:03:55 am »
Here is an official driver for the CMEDIA 6206. It is packaged for windows 10 and includes an example INI file in the ZIP (\WIN10\SoftwareDriver\INI\cm106.ini) which disables all the unneeded features and enables only 6 and 8 channel modes.

After install you still have to open the windows sound control panel and set the card to NOT default and 7.1 mode. I have tested this driver with the EZAudDac.dll and it works fine
I have also tested with 6 channel laserboy waves, Spaghetti and LFI player.

The INI file should be saved to C:\Windows\cm106.ini if its not automagically installed.

Just unzip the above file, run the setup, open windows sound control panel set the driver to 7.1 mode and NOT default, reboot. if the CMEDIA control panel still has extra features (like karaoke mode effects) simply overwrite C:\Windows\cm106.ini with the one included in the zip, uninstall the sound card in the device manager and reboot. The sound card will be reinstalled with the new INI on reboot.

See reference images attached.

Other software / Text adventure

Ok im working on a MUD, its a multiplayer text adventure
its accessible through telnet but i REALLY recommend using a mud client like MUSH Client (google it)

Thats the domain and port for logging in ..

If you do log in please read the message of the day..

because thats where it belongs now

DACs / Scope Shapes
« on: December 15, 2009, 04:18:20 pm »
check this out

it takes DXF files and allows you to rotate them live on your scope thru your sound card
u can also switch between 10 different on the fly.. kinda cool
