Email address which forwards to my Google Voice SMS inbox

NOTE: This question intentionally replicates What SMS email address works for Google Voice? But that is 8+ years old, and the accepted answer does not apply. I guess it would be misleading to place a bounty on that question, users will not understand the “history” of the post. I have a Google Voice number XXX-XXX-XXXX. […]

High side mosfet turn off pulse

I am making a 3 phase motor drive H-bridge using N channel mosfets (IRFB3607) and BJT based custom mosfet driver such that my turn on and turn off time is about 200ns. Right now I am testing the system with a light load of 0.5A at 24V. So during turn off, I see something interesting […]

How to determine what battery to use?

I am making a project that requires two different voltage levels, 5V and 12V (although this can be lowered to 7V minimum). I have two voltage regulators as described by the schematics below: I want to have one power source that can supply enough current and last a decent amount of time to power both […]

Can I resolve a spice netlist to determine what parts I need?

I have used hierarchical schematics in my design, so I can’t really “see” anymore what’s going on behind the scenes. I want to figure out how many of which parts I need… I figured that perhaps the easiest way to do this was by looking at the netlist. However, the netlist includes subcircuit definitions, so […]

What type of capacitor do I need to stabilize USB voltage?

I am trying to use a “FET” (https://elinux.org/RPi_GPIO_Interface_Circuits#Using_a_FET) to switch the power supply to a USB speaker from my Raspberry Pi. It’s working well, however when I turn the volume to greater than 60%, the speaker plays a sound but then dies and disconnects, only to reconnect via USB 2 seconds later. I’m thinking that […]
