Re: Purpose of the cap in this RC Debouncer circuit...
I think I might understand now. I was forgetting about the anode / cathode on the cap. When the switch isn't closed, the circuit is broke, the cap can never charge, right? VCC can't go through the caps anode terminal and then down through the cathode terminal to get to ground, right? The cap would only charge up when the switch is closed, is that right?

Purpose of the cap in this RC Debouncer circuit...
Hello,
I'm trying to learn how to debounce my push-button switches. I'm looking at the hardware way of doing it right now. I've attached an image but I'm curious as to how the cap is actually working in this schematic.
When the switch is closed, wouldn't VCC just travel through R1 and R2 to the NOT gate?
I know that electrolytic caps block DC voltage but allow AC voltage to pass through and I understand why. So, in this diagram here, the cap would charge up and if the circuit was broken, the cap would provide DC and pass it through the NOT gate, right? But the circuit with the cap never gets broken, right? How does the cap actually help to do away with the bouncing effects of a switch?Attached Files -

Hi Everyone. First official post so fingers crossed I conform and also manage to get photos to work.
So I am requesting some help from anyone who happens to have one of these motherboards to hand and perhaps a multimeter.
My board has a single row of header pins for all the front panel stuff (have seen others where they are grouped together differently so thats no help) and the two pins for the power on switch had been previously repaired and I am trying to make a better repair. There looks to be pad and trace damage and im happy to relocate the header pin/pins to...06-24-2024, 01:24 PM -

Hello everyone
Small technical problem on a Nintendo Switch lite
Here's what I noticed: the USB port has been damaged internally, with a short circuit on the power supply line to the small fuse.
After replacing the USB connector, the short circuit went away and I can't see any other short circuit in the whole motherboard.
When I charge the console, it seems to be charging: I get 15 volts and an amperage of 0.450 A.
Then, after a while, the amperage increases to 1.1 A and the BQ24193 charging chip starts to heat up, as evidenced... -
Hello.
Have this GB 2080 Super that crash on load. When half load i see instability on one of two switched 12V rails. I dont know its purpose and dont have BV or Schema for this board.
Can anybody explain me what is purpose of this two switched 12V lines?... -
Hello,
I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.
I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.
I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....
