Hello, the tachometer in my 1st gen 4runner suddenly died, and I pulled it open to look inside to see if it was damaged inside. Upon looking inside, I saw rust on some of the traces and what i believe is capacitor fluid on the chip and a capacitor. The chip doesn't have any visible damage except...

The Universal motor used in a washing machine has a taco which provides a signal via two wires to assist the computer control the washing machine operational speed. When reusing the universal motor for other projects is there an after market type of clock digital or otherwise that can use this...

Hello to those far more knowledgeable on the subject of electronics than I. I guess I'll tell you what I'm aiming for and go from there. Ideally, I've been wanting to create a led tachometer that at least resembles the one from a honda s2000, I'll include an image for reference, but to make it...

Hi guys, I have a fan tachometer signal that is faster than my PLC can manage to read. Is there any readily available PCBs out there, that would be able to take the tach signal, analyse it, and provide a simple ON/OFF output based on the speed?

Hello, I'm currently working on an LED bar tachometer using an LM3914, with the alarm flasher functionality being used as a shift light. I followed a circuit diagram from this post (https://forum.allaboutcircuits.com/threads/led-tachometer-lm3914.37656/) about setting the input to be 0-5v...
