I have a problem with bumping the usb cable that powers my RPI3B+ and it wiggles out and kills power. I was curious if I could cut off the USB end, solder those two wires to female GPOI connectors and...
HiSome of the components used in our designs are difficult to source and can have very long lead times.Do you have a warehouse service where we could store some component inventory for us to use in fu...
It is always seen that audio amplifier work at fixed gain, while attenuating the signal at the input to change the volume. That doesn't sound good since you decrease signal to noise ratio. Also re...
Why does an inductor cause current to lag voltage? Doesn't a conductor need to have current running through it while it is passed through a magnetic field to produce an opposing EMF?
Since I've no experience with buzzers, if there are any good ways to choose the right resistor and npn. By the way, I'm using STM32's MCU, supplied with 3V1 to drive a buzzer (GSC4417YA-16...
I have designed a PCB using the ttgo t-display and other components. I have been attaching it to the PCB that you make for me. Can you install this board to my PCB so I don't have to do it later?T...
Hi all, I need to control the speed of a handful of small pumps independently. The speed is directly related to the voltage supplied. I can't really use pwm and the voltage to the pumps must...
I'm building something with an arduino nano which uses 8 buttons (digital) and 8 potentiometers (analog). I would like to add more inputs to the build, but need to be able to use multiple inputs a...
