How to design any second order passive RC-lowpass (PT2) in seconds: 1. Select the “second order RC lowpass” template. 2. Select the voltmeter. 3. Adjust the “f [Hz]” to the desired 3dB corner frequency. DONE!
Once a little learning curve is passed, CircuitShepherd reveals a new art domain where you can explore highly efficient ways to design analog electronic circuits!
Pro Tip: DC-sweep plots also support a resistor's value as input. Just select the resistor as input in the plot properties!
Since its release, CircuitShepherd has received some significant feature upgrades, which are not shown in the video tutorials!
Insider Note: CircuitShepherd is a hardcore one-man side hustle project by an electronics engineer who got tired of manual parameter tuning in LTspice ;)
Pro Tip: DC-sweep plots also support a potentiometer's alpha as input. Just select the potentiometer as input in the plot properties!

For a second I somehow thought this was excel and I was terrified.
Use a string of mirrored current sources to adjust them all with a single analog potentiometer:
Truly amazing that you don't need resistor drop for the collectors of the 3 transistors. Analog revolution started with current mirrors, the basic ingredient of opamps and more!

@CircuitShepherd This software seems to be very practical, it can see how small the current split flow is. What kind of software is this?
@CircuitShepherd Thanks for the circuit questions. Here is a nuclear power plant operator test question. I post these but no traction. Glad yours do well. I work these out from scratch so only post a few at a time.
Seeing such circuits my first idea is too improve my knowledge of analog transistor circuits. Then I think: 3 GPIOS with 3 resistors and LEDs can do the same via software. 🤪
Use a string of mirrored current sources to adjust them all with a single analog potentiometer:
@CircuitShepherd It has to be s3 as it forces à 0.6V voltage on R1 and limits the current to 3mA. If opened, this voltage becomes almost 23.3V with a 117 mA current way greater than the maximum current the LED can take.
