I was watching this video and the circuit at 2:28 makes no sense because when I learned about parallel circuits, the whole point was how the voltage going into each branch was equal and branches were isolated and theoretically couldn't even have knowledge of other circuit branches. And yet ben talks about how opening the transistor pulls the positive node low and sure enough when he presses the button the LED turns off.
Sorry if this is too basic for the sub or irritating. I'm having a hard time getting google to spit out anything that isn't an introduction to parallel circuits that only re-affirms how branches don't affect each other. I tried to ask r/askscience but the post got removed. Maybe I flared it incorrectly but they didn't have an electronics tag.
Thanks in advance
I have seen some reference designs with a 555 timer, but as far as I know they all change frequency when the input voltage changes. I'm planning on running a simple LED that fades in and out, powered by a supercap, so the voltage will drop over time. How do I make the frequency stay the same?
The example I saw: https://www.555-timer-circuits.com/up-down-fading-led.html
I want to use a capacitor in my circuit to smooth out the signal, but I also want to use the original signal later on, so I have to split the circuit into two independent circuits (I can‘t simply use a diode, because there are negative voltages). How can I achieve this? Thank yall in advance!
Pro Wrestlers apparently only make 5-20 bucks a match when first starting out. Does the same apply to referees?
As the title says, I have multiple (5) GFCI outlets that are tripping repeatedly. They are all on different circuit breakers, and there is nothing plugged into any of the outlets. Some of the outlets are series with other outlets, and I have unplugged everything from the whole circuit, so there is nothing connected anywhere on the circuit. I'm thinking there may be some issue with my common/grounding since it is affecting multiple circuits, but I don't know what exactly it might be or what the next steps are. Any thoughts would be appreciated!
According to the rules for Shutdown circuit, the IMD, AMS and BSPS must have completely independent circuits. I unterstand that the operation of the circuits must be independent, but I'm not sure if it's possible to allocate the 3 circuits in the same PCB. Does anyone know if this is possible or it's considered as dependency between the circuits?
Hey everyone!
I'm Matt Ralston, an award winning writer/director that made a feature film for $6000. We started work on it 3 years ago, shot it in the summer of 2018, won awards on the film festival circuit in 2019 and today, What We Don't Say was released worldwide!
Here's a trailer : https://www.youtube.com/watch?v=YMyyahzziVo&t=3s
It's available to rent or buy on amazon : https://www.amazon.com/What-Dont-Say-Matt-Ralston/dp/B088PBVP6V/ref=sr_1_1?dchild=1&keywords=what+we+don%27t+say&qid=1594741212&s=instant-video&sr=1-1&fbclid=IwAR1Wgbe-hCnq78ZPpfjyc9tEp73g3iXQ-MwB9eKeQb-dMJj-tbTiYe4oPLI
Ask me anything!
Because most are going to be online for some time, national tourneys will be cheaper since theres no need for travel or hotel. But, Idk if I’m allowed to compete (i have an account with my school name). Also i wanna know if hybrids are allowed since my school prtner might not wanna compete and pay, and i wanna be able to have a partner from a different school.
Hi,
I'm having some trouble understanding a start-up circuit for a supply independent reference circuit shown in Razavi's Design of Analog CMOS Integrated Circuits book.

He claims that transistor M5 will provide a path from VDD to GND so as to ensure that the circuit does not start in the 0 current degenerate point state.
How can transistor M5 provide a path from VDD to GND when it's not even turned on in the start? If all voltages are at zero volts, then transistor M3 and M4 are off, then there is no way that M5 can provide a path from VDD to GND?
Whenever i'm looking at people's gimmicks, i see a lot of people who opt for the kind of guy that looks nice but he's got this dark/ emo side and when he comes out, oh boy... you better be scared….
Feels a bit "cringy" and overused...
Also, i'm designing a couple of gimmicks for myself… One would be a Scandinavian wrestler with a Glima background. I'd incorporate some Viking and pagan beliefs stuff.... However i'm doubting wether or not this will get over due to other likewise (but less thought out) gimmicks, like TNA's BRUTUS MAGNUS or the Barbarian back in the 80's or 90's
Some feedback would be nice
