Baluncore's latest activity
-
Baluncore replied to the thread Undergrad How Do You Measure Energy Conversion Efficiency?.That sounds like school or homework to me. You do not. You look at the total energy output in the form you require, and divide it by... -
From AI. I'm too lazy to check it. Publication: On July 25, 2026, Ramana Kumar published an AI-assisted Lean repository containing a...

Baluncore replied to the thread Solderless SMA screw mounting RF issues."Causality" is a product of the way that the TDR can be computed from the S parameters. The resolution of TDR was limited by the rise...
-
Baluncore replied to the thread Undergrad Stability of different X-Frame Spreader Beam geometries.That is true, but as I mentioned in my previous post, the 'X' is over-constrained, and so has too many disadvantages. Something must...
-
Baluncore replied to the thread High School Could instrumental error be the cause of interference in radio telescopes?.There are several thousand satellites, any of which could have transmitted, or scattered a signal. There are too many sources of...
-
Baluncore replied to the thread Undergrad Stability of different X-Frame Spreader Beam geometries.A lifting beam has the hook on the top of the beam. The beam must be able to handle the bending moment at the lift point, and at all the...
-
Baluncore replied to the thread Undergrad Why does voltage drop become more noticeable in longer LED circuits?.For only one LED on, that LED would be operating at the same voltage. For all LEDs on, double end fed would have higher voltage than in...

Baluncore replied to the thread Undergrad Stability of different X-Frame Spreader Beam geometries.The crane cable above the hook will be vertical, with the CoG of the spreader and load being below, on the cable axis. The stability of...
-
Baluncore replied to the thread Undergrad Why does voltage drop become more noticeable in longer LED circuits?.You are too easily persuaded. The voltage droop diagrams shown, are true only for one LED turned on at the time. When all LEDs are...
-
Baluncore replied to the thread Undergrad Why does voltage drop become more noticeable in longer LED circuits?.In these schematics, a LED with a series resistor is represented by a vertical 1k resistor. The resistance of the conductor is...

Baluncore replied to the thread Undergrad Why does voltage drop become more noticeable in longer LED circuits?.The UK ring main is a quite different system, one that does NOT balance the voltage drops. The UK ring main supplies current from both...
-
Baluncore replied to the thread High School The "decagon" on Saturn.There appear to be 11 sides if you interpolate the radials equally around the polygon. That polygonal figure is only visible because...
-
Baluncore replied to the thread Undergrad Why does voltage drop become more noticeable in longer LED circuits?.Where you have an end fed strip of many groups of LEDs, each group with a current limiting resistor, the voltage drop along the supply...
-
Baluncore replied to the thread Undergrad Why does voltage drop become more noticeable in longer LED circuits?.The same current does not flow in the circuit. The supply voltage is fixed, Vs. The LED voltage is fixed, Vd, (by the band gap of the...
