	Small turnout for electronics course. Work done on Rostock. There seems to be a problem with the temperature sensing. The square glass bed broke (there were plenty of replacements).

	Signal lights for safety switches on laser cutter added. Computer control of laser cutter worked fine from 3D printer computer but tabletop computers were unable to control laser cutter. Laser cutter cut extremely poorly; power was coming out of second mirror but was barely getting to cutting surface indicating a problem with the final mirror.

	Hardly any turnout for electronics course. Laser cutter seemed to work at one point after adding a diode in series with the fire line to raise the voltage from .3 & 3.3 V to 1 & 4 V. After cleaning up the control wiring snakepit it again seemed to work (but the safety switch under the control panel doesn't work reliably).		Hardly any turnout for electronics course.

	Masonry blade for new saw brought in. Radon detector showed low one-day Rn level, reset for long-term reading. Temporary terminal strip installed in laser cutter to aid debugging but some connections are inconveniently short. Further testing indicated Smoothieboard output is not open drain which could be the cause of incorrect firing. Work done on getting supercomputer running. All working tabletop computers updated (5VVYKH1 doesn't work, most likely because an update was halted halfway thru at 3:30AM Tuesday morning) & new file update.txt created giving the date of the most recent update & any files that were not updated because they had been modified. Discovered a few cases where programs that had definitely been installed (listed in installed.txt) were no longer present.		Masonry blade for new saw brought in.
