If someone gives me left-top-front etc views of a neo case... I can try to do something with SolidEdge (academic version of SolidWorks). I can't promise exactly when, maybe this weekend.<br><br>(And it would be helpful if neo's curves were circles and not complicated splines... :D )

<br>><br>>> for a start that some of us have made on the wiki. is anyone with a<br>>> GTA01 up for whipping out their micrometer/3d scanner and knocking<br>>> something together?<br>>> even better, is anyone at FIC/openmoko able and willing to provide us
<br>>> with detailed drawings of the case?<br>><br>> If this doesn't happen before next wednesday, remind me and I'll measure<br>> up one of my GTA01s with my digital micrometer. I happen to be 1000km
<br>> from it this weekend (my micrometer not my neo :-)<br><br><br>Would be great if somebody did a really thorough job of documenting the<br>Neo case. In other words, disassemble a Neo as described here:<br><br><a href="http://wiki.openmoko.org/wiki/Disassembling_Neo1973">
http://wiki.openmoko.org/wiki/Disassembling_Neo1973</a><br><br>and make nice orthographic images of all the case parts, from all angles<br> -- back, front, edge-on, etc.<br><br>The easiest way to do this is to simply place the parts on a flatbed
<br>scanner. And put a pair of short rulers on there too, at right angles,<br>for calibration (millimeter scale!).<br><br>The orthographic images produced in this way aren't perfect, but they're<br>a lot better than what you get with an ordinary camera, at least for
<br>some purposes. You don't have to worry about camera angles and such,<br>and the resolution is potentially much higher too.<br><br>By all means, make lots of measurements with the micrometer, everything<br>you can think of that might be useful to somebody who wants to hack
<br>hardware or design add-on parts. But with some good orthographic images<br>uploaded into the wiki, people would have an opportunity to make<br>measurements that weren't thought of when the micrometer measurements
<br>were made, or that aren't easy to make with a micrometer.<br><br>Some non-trivial things to measure include draft angles and radii of<br>curvature (there are lots of these, as molded parts rarely have true<br>sharp corners on them -- these corners are usually "radiused").
<br><br>Use a high resolution, true color, PNG format. Leave the scanner lid up<br>and turn off the room lights for a nice black background.<br><br>Yes the image files will be large. I don't mind, I have broadband. :)
