This does not mean that I did not find much that was wince-worthy. ,
Ah ha!
So you're the infamous Chris! I've heard about you from Mel, and I think that I've spoken too everyone else at ilxo on irc or the phone except for yourself. Anyway. I was browsing the hardware articles you've been working on and I'm impressed. Good work. There is a pretty lively Flickr OLPC group that I manage, one of us should upload your photos as another method of distribution. Seth 21:05, 31 May 2008 (EDT)
Bridge Design Handout
Chris,
Any chance of getting that bridge designer activity referenced in the lesson plan rewritten as an activity?
I went to the jhu site and played with it a little. It would seem to be a natural fit as an educational activity.
As a model railroader I also feel like pointing a couple of MR lists to it. Frequently there's the 'does this bridge make any sense' discussion.
Do you know what it is written in? Any encumbrances to using it? Or may the simplest solution be (ahem) reengineering it?

I like that idea, though I don't have a lot of time to put together a bridge building activity for the XO at the moment. I'll start doing some work on it toward the end of summer.

IBM AC/DC combo power adapter
You might want to try to get your hands on a couple of "Lenovo AC/DC combo adapter 73P4503", this is the 72 watt version, I think there is also a 90 watt version. The tip works okay in the XO (maybe a little extra wiggle, but it works). The really cool part is that this can either plug into wall for AC source, or you can use the cigarette light adapter to plug into 12V DC source. Figure out what's inside one of these and you're well on your way. Cjl 17:38, 10 June 2008 (EDT)
Voltage_regulator
Voltage_regulator is uncatagorized. But seems to be a work in progress. Could you categorize it please? 18.85.47.91 05:45, 2 July 2008 (UTC)
