All 30 of Massie’s patents were on the same invention: haptic feedback in VR. Developed while a student in Cambridge, not in Boone County.

Resistance mode on a multimeter can damage individual diodes, lamps, or gates in an electronic circuit. chatgpt.com/share/68b0e417… Some electronic components burn out over 1 volt and some multimeters put out a few volts in resistance mode.

youtu.be/aB2v-2C4HJI Wavefronts of hot resin are cooler than the bulk of the flow behind it. When cool wavefronts meet after parting around a hole, they leave a mechanically weak weld-line. Capillaries can quickly cool a hot resin to reduce cycle time.

60% of a car engine’s power gets lost due to friction in the pistons. howacarworks.com/video-course/w…

The empty/full fuel needle on your car may be controlled by a wiper resistor tied to a balloon. youtu.be/NGyfHHk_VAw?si… Fuel in the tank lifts the balloon, which wipes the potentiometer which signals where the needle indicator should go.

mills had to transmit enormous amounts of power, doing so with belts or ropes. Someone discovered that multiple belts in multiple grooves transmitted better than a single belt. youtu.be/Mz5PMJMLhSE?si… The V belt is recent. Hard tugging wedges it into the groove of the pulley.

A nice wood mounted, pulled apart starter motor, broken down for students: youtu.be/SYLDMb7HHZ4?si…

A starter motor is small because it doesn't need large cooling fins. youtu.be/VRe_hKxzKUg?si… Only runs for a few seconds= no need to cool, despite being almost 5 kW (400 CCA).

Tim Hunkin has just released remastered versions of The Secret Life of Machines. I can't emphasise how great these shows are - the pinnacle of TV education. The first four are now on YouTube: youtube.com/watch?v=SgWh-5…

I found the ultimate tool. It is so powerful it literally cannot be used.
