Baluncore replied to the thread Question about causality in s-parameters.With TDR of any form, everything beyond the second step or kick, becomes indeterminate pinball insanity, in a hall of mirrors. -
Baluncore replied to the thread How to measure the diameter of a shaft without a caliper?.The helix measures the hypotenuse of a triangular wedge with a height of the thread diameter and a base of the (shaft + thread... -
Baluncore replied to the thread How to measure the diameter of a shaft without a caliper?.There are two effects, the length of a helix turn, which is of minor importance on big diameter shafts with small threads, and the... -
Baluncore replied to the thread Running older induction motors on VFDs.If you can hear a buzz when a motor runs on a VFD, then that vibration may chafe the field coil insulation. The buzz is the sound of the... -
Baluncore replied to the thread Running older induction motors on VFDs.Snubbers in this case would be RC networks that make the output look like a low resistance at high frequencies. That will attenuate the... -
Baluncore replied to the thread Running older induction motors on VFDs.Not at the motor terminals, but at the inverter output. The voltage switching outputs need to see an inductive load. Wind three... -
Baluncore replied to the thread How to measure the diameter of a shaft without a caliper?.What is the approximate diameter of the shaft? 1mm, 10mm or 100mm, it makes a big difference. Maybe use an AF specified spanner/wrench... -
Baluncore replied to the thread High School Spotting 1997 NC1 flyby on Fri/Sat.Maybe when it gets brighter it will be listed here: https://www.heavens-above.com/Asteroids.aspx -
Baluncore replied to the thread High School Spotting 1997 NC1 flyby on Fri/Sat.I would start here: https://astro.vanbuitenen.nl/neo/1997%20NC1 https://newton.spacedys.com/neodys/index.php?pc=1.1.3.0&n=152637 -
Baluncore replied to the thread Method of storing energy on the Moon.I expect the first significant lunar power will be required by the robots to install and operate this radio astronomy project. The... -
Baluncore replied to the thread Method of storing energy on the Moon.Yet, without our messing with it, it is the Sun that provides that service. -
Baluncore replied to the thread Method of storing energy on the Moon.At the same time, it may not actually be necessary to go to the Moon. I am including concepts at this stage, not trying to rule them... -
Baluncore replied to the thread Method of storing energy on the Moon.The biggest advantage of lunar satellites would be the lack of an atmosphere, so the orbit could be very low. The orbital period could... -
Baluncore replied to the thread Collection of Science Jokes P2.1/12 scale is the standard and most common scale for models and traditional dolls houses. In the "one-inch scale", 1 inch in the... -
Baluncore replied to the thread Method of storing energy on the Moon.Yes, but not circling the lunar equator. Lunar libration of about 10° would require the cable cover 190° longitude of the 80° line of...
