    Nah I was too lazy today to go to my workplace. I can pick one up tomorrow, I also have FTDI breakouts just for testing, because with that the original software should work just fine.

    The method for building the fw for the serial chip is quite simple:

    1. download LUFA 100807 http://www.fourwalledcubicle.com/fil...UFA-100807.zip
    2. put the arduino-usbserial folder into LUFA's Project folder
    3. change these lines in Descriptors.c
    .VendorID=0x03EB,// Atmel
    .ProductID=0x204B,// LUFA USB to Serial Demo Application
    to this
    .VendorID=0x2341,// Arduino
    .ProductID=0x0001,
    4. make all
    5. install flip http://ww1.microchip.com/downloads/e...03.4.7.112.exe
    6. plug in your arduino
    7. short the 2 pins on the 16u2 spi header closest to the usb port on the UNO (resetting the chip, entering DFU mode)
    8. install the dfu drivers, they are in flip's folder in program files.
    9. use flip to upload the compiled hex.
    10. unplug and plug back in the arduino.

    Well it's a lot of steps but most of them are one time only.

    Hope this helps

    Cool, thanks for the write up. I am sure it will help (me and others if they find this too).

    I cannot find my real UNO. I must have given it away or blown it up. Lots of clones and a Leonardo (Atmega32u). I will put an UNO R3 on order.

    In the meantime I will try to get the software to a state where you can try it out with a COM port based interface. This will work for both the FTDI chips and other chips as long as they have a CTS line. While some Arduinos have a pad for easy access to the CTS pin some you have to solder to the USB to Serial chip. The original boards I designed this for (Diecimila) had a breakout header for the flow control lines.

    I tried the way back machine.... searched for "my missing UNO" .... 345 billion archived web pages and no UNO to be found.

    I've made a dirty UNO R3 hack that works for me so I can at least try my laser.

    Do you guys have any suggestions on software? I've bought the LaserShowGen because that was the cheapest, but I'm open for suggestions for anything. I'm a total noob, just started this "hobby" so anything helps really.
    (I'm pretty good with laser safety so you can skip that part, I do have industrial laser cutters safety googles ect. and I'm very aware of the hazards when working with lasers)

    I'm not giving up on making the UNO R3 work with this DAC I just needed something that works and I'll be on a holiday from tomorrow.

    LaserShowGen works well. http://pages.bitlasers.com/lasershowgen/

    Spaghetti Laser Show ($89 USD) is also good for making shows and viewing them. (needs the MLD driver) http://www.spaghettilasershow.com

    HeLaserScan works pretty good (free/donation?) (needs the MLD driver.. V5 works with the drivers from my site, V6 I am working on the driver as there is some sort of crashing issue). There is a lot of features in this software and there are some nice shows that can be downloaded.

    LaserShow XPress is very comprehensive. ($129 USD for the Lite version) The only issue with this software is that professional shows cannot be played back with the open source OLSD driver. https://innolasers.com/shop/index.ph...roller=product

    what do you mean by "professional shows cannot be played back with the open source OLSD drive"?

    suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

    I mean if the show is locked like the demo shows that come with LaserShow Xpress they don't output to the Open Source OLSD driver (OLSD.DLL). Andrew has a version that is not Open Source but works with a special version of the firmware (also not Open Source). This is so someone cannot bypass the locked/encrypted shows by making an OLSD driver that writes to an ILDA file therefore bypassing the copy protection. That is what I mean.

    That being said you can play your own shows you make and shows that aren't locked (I forget the actual mechanism so I am using the word "Locked" as a blanket word). I like LaserShow Xpress a lot. It is the most powerful out of the bunch.

    oh. you mean the protected show content.

    yes, that makes sense.

    Probably its just me being lame but HeLaserScan would only start for me in demo mode with dummy output devices, seems like I have to buy the software to make it work. Also, the site is in german and I can somewhat understand most using google translate but the whole site is just akward for me. Or maybe there is an earlier version of the software that is free and able to use OLSD? How do you guys using that sw?
    LSX is out of my budget at the moment, I just built the laser and the dac for fun I'm not planning to use it a lot. I'm more interested in tinkering with the hardware and software as a fun thing.
    By the way, the laser I got is only TTL so I should build an analog driver for the diodes, do you have a schematic recommendation that works well for you?
