Baluncore replied to the thread Running older induction motors on VFDs.I think the two channel amplifiers are saturating before the subtraction is done. You need more attenuation. Do you have a neutral... -
Baluncore replied to the thread Need a technical term for part of pressure hatch.Hard points are usually tapered, and called Dog Keepers or Dog Catches. -
Baluncore replied to the thread High School What if we could use a Black Hole as starship?.There is no escaping the fact that both point A and point B must be within the event horizon. -
Baluncore replied to the thread High School What if we could use a Black Hole as starship?.To accelerate a starship, to the maximum speed, using a fixed energy, requires a starship with minimum mass. That is inconsistent with... -
Baluncore replied to the thread Undergrad Why the initial choice matters in the Monty Hall problem.The player selects one door of three. That selected door comes with a frozen probability attached, of 33% that it will win. Then one... -
Baluncore replied to the thread Cray-2 Supercomputer Comparisons.46 years of Moore's law can make a difference. 221 = 2.1 million. There is another difference between a Cray-2 and the iPhone 14. The... -

Thanks! I did have CT surgery about ten years ago. This is more a side-issue of deep thenar pain, maybe tenosynovitis or basal joint... -
Baluncore replied to the thread Running older induction motors on VFDs.How to wind a coil faster, and more safely, with less pain. Get a nerve conduction study to confirm CT. If CT get the surgery. If RSI is... -
Baluncore replied to the thread Implementing Kramers–Kronig causality check on real VNA s-params.Causality Verification Using Polynomial Periodic Continuations for Electrical Interconnects... -
Baluncore replied to the thread Copper piping and cathodic protection?.Rainwater is usually pH 5.0 to 5.6. If you measured pH 7.0, then it has been neutralised before you sampled it. If you sampled the... -
Baluncore replied to the thread Copper piping and cathodic protection?.Rainwater contains dissolved CO2 which forms carbonic acid, H2CO3. Carbonic acid will react on the zinc surfaces to form a white... -
Baluncore replied to the thread Running older induction motors on VFDs.First find the AL value for the core. Wind a test coil of say 10 or 20 turns, then measure the inductance. AL = uH / turns2. uH = AL *... -
Baluncore replied to the thread Implementing Kramers–Kronig causality check on real VNA s-params.It will depend on the format of the data available. Google AI to find papers and code. -
Baluncore replied to the thread Implementing Kramers–Kronig causality check on real VNA s-params.To work perfectly, Kramers-Kronig requires a bandwidth from DC to daylight, but perfection is impossible, so you must settle for less... -
Baluncore replied to the thread Copper piping and cathodic protection?.Zinc is an essential trace element for humans. Zinc is not a problem where houses have zinc roofs and zinc water tanks. There is...
