A wonderful SX28 board with USB, EPROM and 24 volt drivers - Where?

A box of goodies arrived from Parallax today, including my HP Printer kit.

I was very surprised by the enclosed board as it has an SX-Key interface along with several other features -· 24volt outputs to 12 lines, USB input, an on-board EPROM, dual power supply, i/o to a BasicStamp.

Simply, it is open to reprograming.

I am sure I haven't properly figured it all, but if I ever get tired of Inkjet interface, the board offers numerous other possilbilties and just may be worth many hours of hacking.

And of course, you have the Inkjet too.
I didn't realize that it was so involved either.· It seems that you can't just fire away with dots as they aerodynamically interfer with each other, so they only fire in distant pairs.

    You're right, Kramer -- heck, John Barrowman and I did the hardware (JB) and software (JW) for that project, yet we never once talked about "hacking" it as a controller for the EFX group that the two of us started!

    Well, I actually imagine for EFX, the 24volts output might be an advantage as you might have to drive some long wires that tend to drop voltages.

    My first impression was to trade out that 24volt switcher with another lower voltage chip at some point, but I doubt I will ever do it. I am really enjoying the HP Inkjet more than I originally thought I would. I'd prefer to keep it intact.

    I am pleased to see the SX/B code for it is included. This provides insight in how to combine serveral functions into a working whole. It is a model for transfering data from your PC to EEPROM through a USB interface too.

    If you need 12 outputs at a high voltage [noparse][[/noparse]a fireworks display?

    I am certain to learn a lot from it.
