Slowing FET edges

January 27, 2021, 5:38 pm

Tasked to PWM a resistive heater, a 1us gate drive risetime seemed plenty pokey enough. Certainly slow-mo compared to our usual speed-quest. So I was surprised to see fall output times Read more »

Computer interface to a multi-device IR remote control (or functional equiv...

January 27, 2021, 5:08 pm

In an attempt to have one remote control to control a suite of devices (TV, cable box, AVS, etc.) I got a logitech harmony some years ago. Basically happy with it aside from some times the state... Read more »

OT: "We can stay retarded longer than they can stay solvent.?

January 27, 2021, 11:25 am

A fascinating thing is happening on Wall Street. GameStop stock has been p ushed to astronomical heights over just the last week or so. It has taken down a hedge fund that had overly shorted it.... Read more »

Procedure for inverse Laplace transformation to calculate periodic switch-o...

January 27, 2021, 2:39 am

Hi, The calculation of switch-on processes according to Laplace often involves the problem of transforming back into the time domain. The inverse Lapace transformation is almost impossible to sol... Read more »

Phil - SAV551

January 27, 2021, 12:03 am

I built my triggered SAV-551 Colpitts oscillator, at 130 MHz. You recommeded using a gate resistor, so I used 4.7 ohms 0603 as a placeholder. Jitter was ghastly; the phemt was clearly oscillating ... Read more »

January 26, 2021, 9:15 pm

email.me: You are an abject idiot. I have made three posts in 6 months. Decidedly makes you the hyperactive troll, you retarded putz. And your retarded setting of followups to non existent ... Read more »

White House In Danger Of Imminent Collapse, First Family Evicted

January 26, 2021, 1:22 pm

Should have been the headlines in 1949 but it was kept secret. Apparently 1 8th century architectural practice was unaware of the dangers of building a foundation on sand. The building was comple... Read more »

STmicro acceleration/magnetic sensor LSM303DLH == LIS331DLH + HMC5834?

Just had a look at the LSM303DLH datasheet and had a déjà vu ;-) It looks like ST has simply put a LIS331DLH and a HMC5843 into one package. (The HMC lacks the built-in voltage regulator) All data ar... Read more »


LT Spice schmitt oscillator

  [ 2 ]

Does anybody have a working LT Spice netlist for a simple schmitt inverter/R-C oscillator? I tried one using the library schmitt inverter and get obscure sim errors, and I don't understand the HELP ... Read more »


propagation velocity experiment

This would involve CK722 transistors, slotline samplers, and pecan pralines [1]. Unit of measure would be kiloseconds. Let's see what happens. John [1] The crunchy kind, of course. Only Yankee touris... Read more »


How to isolate 5V and 12V circuit

Hello everyone, I have extend existing circuit design by adding a 12V relay to it. AT the moment both 5V and 12V circuit are side by side. This doesn't work well. Intermitent device failure happen. I... Read more »
