crutschow replied to the thread How is coating wear on ESD tweezers typically assessed in production environments?.What is the purpose of this "anti-static" coating on the tweezers since they are made of conductive metal? Does the lack of it affect... -
crutschow replied to the thread Found problem in Kenwood KR-V95R.Hopefully. But the OP hasn't been seen here since 2020.

crutschow replied to the thread Latching relays in a control circuit.My question was whether you could wire and solder the parts on a vector board if given the circuit schematic and the parts required?
-
crutschow replied to the thread Latching relays in a control circuit.It can be done with some simple logic circuits if you are up to building that. What are the relay-coil voltage and current requirements?
-
crutschow replied to the thread Cat door sensor jammed by steel (metal) enforced wall.The plastic is just to provide more space between the sensor and the metal wall. It does nothing by itself otherwise to block the...

crutschow replied to the thread Television reception antennas farce....And what will you do if you have that info? I would think the antenna gain vs. frequency (into a fixed load) would be of more interest.
-
crutschow replied to the thread Ignition coil....Doubt that you get more than a few hundred volts at 60Hz, which likely is not enough to go through the hair to skin of most animals...
-
crutschow replied to the thread Cat door sensor jammed by steel (metal) enforced wall.So what about adding wood trim to replace the removed metal? What is the purpose of the metal wall?
-
crutschow replied to the thread Cat door sensor jammed by steel (metal) enforced wall.Could you trim the metal away from around the opening?
-
crutschow replied to the thread Cat door sensor jammed by steel (metal) enforced wall.The metal wall apparently acts as a shield that prevents the ready from functioning. Where is the metal in relation to the mounting...
-
crutschow replied to the thread Ignition coil....12Vac would likely saturate the core, causing the primary current to be limited only by the primary resistance. It would increase the...

crutschow replied to the thread Loop parasitic.Resistors?
-
crutschow replied to the thread Max Current and Shorted Current.The shorted current will be slightly larger than the regulated voltage maximum current, due to the low gain of the current limit...

crutschow replied to the thread Buck converter calculation does not match with LTspice results.So everything looks ok now? Note that the high frequency oscillations you are seeing at the output of the switch is due to the stray...
