  Thanks! I remember seeing that a long time ago and thought it was pretty neat.

  Hey everyone, a couple years back I made a project with the propeller called the Pixelmusic 3000 and created a walkthrough for Make Magazine. Make has created a new, free project site and put the project up there for all to toy with. The source code and schematic are up, as are all the instructions to make one yourself. Check it out and let me know if you make one! http://makeprojects.com/Project/Pixelmusic-3000/606/1

  
  Hey!
  
  I have built this thing on my breadboard now and its looking really good! Only problem is I can't make the chip power up and run without sending the scetch over usb-serial first. When I DO do that it runs smoothly, and I can remove the usb connection and it still runs nicely. But if I then remove DC and re apply it it does nothing. LED does not power, but circuit is measuring 3,3V. I don't understand this! Do you?

  Sounds like you are using F10 or Load to RAM. This only loads the SPIN program to the Propeller's RAM and once it loses power, the propeller will run whatever is in the EEPROM. If you use F11 or Load to EEPROM, it will load the program to the propeller's RAM and then copy it to EEPROM for future boots.
  
  edit: I just noticed the MAKE article states to use F10 to load the program. Can you update that tk3000?

  Looks very cool! There's a lot of tearing going on though; is there a way to eliminate that?
  (At least, the video referenced on the make site shows a lot of horizontal tearing.)
  
  Any way to synchronize the generation/update to the vertical blanking interval? The prop
  should easily be fast enough to keep up with the vertical beam.

  Hi! I know this Pixelmusic 3000 stuff is a bit dated, but I'd really like to build one. I gathered all parts.......but I cannot get my hands on the SPIN source code! All URLs, articles, etc. I found on the net are either dead or lead to the Make Magazine project page...which doesn't provide neither the schematic, not the SPIN source code.
  
  So, if there's anybody out there willing to provide me with the source code, that would be HIGHLY appreciated!
  
  Thanks in advance,

  Had to hack the internet a bit, but here is the original code from 2008. Unfortunately, the code was only on the Make site originally and they messed up the link in the article. The Make site has been restructured since then, so the code was probably dumped as an orphaned file. With some Google tweaking, I found a PDF in Spanish that contained a full link to the newer location of the code (which was dead) but it at least gave me the full path of the latest file. From that, I used the wayback machine to get to the original file.

  Hi Andrew,
  
  man, that's phantastic! I never got that close to the links while I was researching.....using the way back machine was a thought that didn't cross my mind. So, thanks for all your efforts, and for providing "living" links. I really do appreciate that!
  
  Best regards,
