Steady Turn Plot about origin
A plot exhibiting right handed stable steady turns with positive steer torque, near the upright zero steer configuration read more...
Multiple SSH key pairs, some with passwords and some without
I needed to setup some ssh key pairs that could be used with cron jobs, thus not requiring a password. But I also needed to have passwords on some of my other server connections. This is how I did it. read more...
Stable right hand steady turns with right hand applied steer torque
According to the nonlinear equations of motion of the benchmark bicycle model that I have derived, stable steady turns to the right do not always require a left handed steer torque. read more...
Very cool papers proving gyro and caster aren't required for bicycle stability are out.
Jodi Kooijman et al just published a paper about a neat little "bicycle" they built that is stable even though the angular momentum of the wheels is negligible and the trail is slightly negative. read more...
