    Bypass Capacitor Using Recommendations

    Hi, all I have built new crossovers for my Thiels using mostly Clarity CSA caps. On the coax board, the two feeds and subfeed are bypassed with Multicap RTX (~1%). I am super happy with the SQ improvement. Well-recorded music sounds fantastic, just sublime. Really hard to fault, especially at...

    High voltage divider circuit to run an LED?

    Thank you for helping 🙂 I have a bunch of 1k, 1/4W resistors, so 10 of those will work fine. I guess that 6mA at 60V is only 360mW, which might be a bit high. I could always use a lot more resistors and experiment by reducing it until I get to a suitable brightness.

    High voltage divider circuit to run an LED?

    Good day, all 🙂 Recently, I have a system running at 62V max, 54V nominal based on voltage divider rule formula. I wanted to have a little alert LED, so I was thinking about using 10, 1kohm resistors, and adding the LED bewteen the 9th and 10th (or 1st and 2nd, if it matters), to get at most 6V...

    Sink current using PCA9685?

    Hi, all I'm using a PCA9685 with a pinout board like Adafruit's. I'm trying to run a bunch of LEDs at 20 mA, and the chip is supposed to be able to source 10 mA and sink 25 mA. I understand that to have it Source, you connect the LED between the PWM and GND pins and to Sink you connect it...

    Introduction to Non-Inverting and Inverting Amplifiers Basics

    In electronics, a non-inverting amplifier is an op-amp circuit configuration which produces an amplified output signal. Its output signal is in-phase with the input signal applied. And non-inverting amplifier always behave like a voltage follower circuit. There is less info anout non-inverting...
