Current idea: Wiki integration using built-in version control capability (diff, history). Code contributors need to provide companion png and ogg files for visualization. It would be nice to have a web service to generate media files from wiki code automatically. (DirkS is looking into this)
Animation of DirkB riding hands-free and walking baby python w/ cargo, File:FoldingPythonDesign02b.ogg (testing how ogg video file appears here, but no thumb or still image)
when the video plays, the link shows http://en.openbike.org/images/openbike/d/df/FoldingPythonDesign02b.ogg
Sample code:
// main parameters
s = 1; // scale from inch
rider=true; //
c_frame=[1,0,0]; // red frame color
a_seat = 40; // 20 to 70 degrees clock-wise
a_pivot = 60; //
front_wheel = 20*s; // 10 to 26
rear_wheel = front_wheel; //
wheelbase = 45*s; //compromise bt weight ratio * compactness;
// assemblies
translate([-wheelbase,0,d]) wheel(w=rear_wheel); // rear wheel
python01(); // front wheel, chain stay, BB
//pivot
translate([-ttt*sin(a_front)-4*s*cos(a_pivot),0,-ttt*cos(a_front)+4*s*sin(a_pivot)])
rotate([0,a_pivot-90,0]) cylinder(h=8*s,r=s,$fn=20,center=true);
// rear tube
color(c_frame)
{
translate([-wheelbase+h_rear/2*sin(a_rear),0,d+h_rear/2*cos(a_rear)]) //
rotate([a_rear,0,90]) roundedBox([0,2*s,h_rear+2*s],1*s, false); //
translate([-wheelbase+t4-h_mid/2,0,z_pivot]) //
rotate([a_mid,0,90]) roundedBox([2.5*s,2.5*s,h_mid+2*s],1.25*s, false); //
}
// rider & seat
translate([-48*s+BB2FWA+crank,0,z_pivot+14*s]) //
{
rotate([90-a_seat-atan2(26*s-front_wheel,55*s)/2,0,-90]) //
scale(2*s) color(suit) groomRider(); //
