Massive Solar Flare gets HD Close Up
Take a closer look at the flare that erupted on March 6, 2012. This movie of the March 6, 2012 X5.4 flare was captured by the Solar Dynamics Observatory (SDO) in the 171 and 131 Angstrom wavelength. One of the most dramatic features is the way the entire surface of the sun seems to ripple with the force of the eruption. This movement comes from something called EIT waves -- because they were first discovered with the Extreme ultraviolet Imaging Telescope (EIT) on the Solar Heliospheric Observatory. Since SDO captures images every 12 seconds, it has been able to map the full evolution of these waves and confirm that they can travel across the full breadth of the sun. The waves move at over a million miles per hour, zipping from one side of the sun to the other in about an hour. The movie shows two distinct waves. The first seems to spread in all directions; the second is narrower, moving toward the southeast. Such waves are associated with, and perhaps trigger, fast coronal mass ejections, so it is likely that each one is connected to one of the two CMEs that erupted on March 6.

Four Cable Drawing Machine
This is a cable driven drawing machine I constructed for the Telus Spark Science Centre in Calgary, Alberta. More information and construction details are on my blog at: http://dbynoe.blogspot.ca/2013/12/four-cable-drawing-machine.html Each of the four stepper motors is connected to a pulley and string. By winding in or letting out string on each corner the computer can position the draw head anywhere in three dimensional space, or at least within its work envelope of roughly 590x590x220mm. The machine is controlled with LinuxCNC using a custom kinematics module and python script written by Kevin Loney. Its input files are standard g-code, the same format used for controlling a CNC mill, all the weird coordinate transformation math is handled by the kinematics wrapper. Accuracy is pretty good, theoretically it can position itself to about 0.1mm, this breaks down near the edges of the draw area as the cables sag, leverage, and a variety of other interesting physics effects take hold.
