  1. Hi there! I'm the original author of the chatpad reverse eng/firmware, and I just discovered it was been featured on the Ben Heck show because a student contacted me with questions about it. This stuff happens often with many of the project I used to release back in the days, and I just wanted to take a minute to tell you how awesome it is to me. Keep sharing!

  2. how convienient! choosing a keboyard with an internal header that can be re-programmed with…and element14 pic programmer!

  3. i expected something like an pc-xt 8086 or some comodore 64 or something, not an arduino project with an xbox keyboard. it is great, but not what i expected.

  4. "I found someone who had done this whole thing"… WHO?? WHERE?? How about some frelling links to your sources? Presenting a project wherein you say, essentially, "I'm using somebody else's work but I'm not going to tell you who or how I found it" is pretty frustrating to those who might want to try it for themselves.

    At any rate, it looks like a lot of stuff about reflashing that chip has been lost to history; however, here is a very useful page that still exists about understanding the chatpad's actual default protocol (which one could then translate with an Arduino or other such chip):

  5. Hey ben!
    I've seen your show and I do like it.
    I primarily work with programming of the batch language for PC and XP, I'm looking for a build that uses the Arduino mega as a robotic control for movement but can permanently connect to a separate computer (Hardline) but smaller than a laptop.

    Basically what I want to do is build a full-on robot, that is small enough to do basic household chores similar to the ones that you would see on the movie Flubber

  6. could you tear down the samsung dex and put it into a laptop case and have it slid in the bacl or anywhere really. i want to build one, i figure it wouldnt be too difficult.
