<br>* [Message7] (Regular feature) Question for discussion<br clear="all"><br>------------------------------------------------------------------------<br>Message 1 -<br>
------------------------------------------------------------------------<br>Hi,<br> I am currently working on the software framework to allow<br>easy analysis of data. Specifically, I am making a system for<br>representing both functions and buffer based (collected) graphs
<br>on the same canvas and how to make them interact effectively.<br>I have also built a very primitive GUI. Hopefully I will combine<br>these by this weekend, so I can get hacking on various sensors.<br>The goal is then to provide pre-designed setups so that one can
<br>e.g. click on the temperature probe, hit collect, and start getting<br>data. After that, along with refining the GUI, designing some<br>useful sensors is in the todo list. Finally, integration with the<br>camera and mic/speaker (for distance measurement) will be
<br>added. This is a long term schedule -- for the next two weeks,<br>I would like to get the GUI and functional/buffer based graphs<br>(including regressions, etc) working. I have never used Gstreamer<br>before, so that is a hurdle that I am trying to cross (or, better yet,
<br>avoid by using pyalsa...).<br> While I would like to devote all my time to this project, that is<br>simply not possible, so I am working on it as much as I can. This<br>varies from week to week, but I should have a looser schedule
<br>now than I did until mid/early December. If anybody is interested in<br>helping me work on this or wants to coordinate functions, they<br>can feel free to contact me at <a href="mailto:nicholas.a.sinnott-armstrong@dartmouth.edu" target="_blank">

hi, <br><br>i am, hopefully, getting an iodata usb2rgb (usb vga dongle...) cable soon,<br>and will be devoting some of my OLPC time to that - probably mostly<br>integration work, so that we can hook olpc to other display hardware
<br>(projectors, etc) when needed.<br><br>i'm also interested in working on integrating wiimote control with the XO.<br>again, a lot of that is integration work :-) but it makes several<br>different kinds of sensors trivially available, modulo the availability of
<br>a bluetooth dongle.<br><br>i'd love to work with someone on adding <a href="http://processing.org" target="_blank">processing.org</a> hardware / arduino<br>programming activity support to xo. cool stuff, those projects are, and
<br>
pushing them together with OLPC is an interesting synergy.<br><br><br>--elijah<br><br>

Hi all,<br>My current projects include the various I/O devices for the XO, but my focus is the TeleHealth Module. I am trying to design a peripheral, application, and library for the XO to successfully bridge the "last-mile" gap between the medical community and the children of the third-world. My work on the activity still remains trivial at this point in time, as I am relatively new to python. My work on the hardware is outlined in depth on the wiki page, [[TeleHealth_Module]]. I am still working on obtaining the few remaining components via samples, and am currently struggling to obtain an oscilloscope and developer boards for my surface-mount components.
<br><br>A bit about me: My heavy involvement in OLPC precipitated after I was severely burned on my left hand by a plasma cutter. I have since learned much about medical diagnosis technologies and protocols. I am a chemistry hobbiest, electricity enthusiast, Wikipedian, sustainability advocate, and student. There's more to be said, but some of it is on my wikipedia user page, [[User:ITxT]]
<br>I look forwards to collaboration,<br><br>Ian Daniher<br><br><br>------------------------------------------------------------------------<br>

<br>(Joel would be presenting OLPC at an important conference soon - on the 20th of November, Please help him with peripherals ideas and designs) Joel says...<br><br>Hi, <br>I'm presenting OLPC at a big education conference in two weeks time
<br>(nov 20th) and I'd like to demo some of the different bits that we<br>currently have.<br><br>Would you able to send me the designs that you currently have, so that<br>I have enough time to put the parts together before the conference?
<br><br>Also, consider this a my registration of interest for any hardware, or<br>software, assistance required for any peripherals development.<br><br>Cheers,<br>Joel<br><br>------------------------------------------------------------------------

Have you checked out the $1 Microscope ?<br>"The microscope, which is said to have ~ 100× magnification, could be useful to analyzing water quality, among other things.

------------------------------------------------------------------------<br>[Regular feature]<br>The question for discussion in this edition of peripherals update is -><br><br>What is it that forms the main inspiration for you to develop a peripheral around the XO ? Is it...
<br><br>* to enhance children's learning ?<br>* to help the community of people where laptops will be deployed, with a useful device ?<br>* build a cool device around the XO ? :-)<br>* Any other ?<br><br><br>------------------------------------------------------------------------

------------------------------------------------------------------------<br><br><br>-Arjun<br><br>ps - do we really need a separate mailing list for all this , wouldn't we get more participation if all this was posted on devel and/or sugar initially ?
