Hey guys
is it safe to put a 16v rated capacitor behind (to the output) of a 7815/7915 dual supply regulator? I have some lelons laying around that i want to use for the a hifi project. will the capacitors blow, or is the regulator stable enough to be at a constant 15v?
thanks
hey guys, so back to my amplifier project, do i need to pair the two mosfets on the output level? i do realize there is a gain control resistor i was wondering if i could tune that instead of buying paired transistors.
how can i make a 120v dc power supply for hi fi audio (super flat signal) without the need of a super large regulator or capacitor? (the capacitor would have to be 27000 uf @ 160v)
any help appreciated
thanks
hey guys, i know this question is very unfeasable, but can you roll your own capacitors? i need a very large capacitor, a couple farads big, and up to around 150 volts. is it possible?
hey guys, so i wanted to do a project that involved connecting a usb device to my home theater pc that draws significant power (>300ma). I want to be seated on my couch, and have freedom of movement while the cable is not lying in the middle of the room, so i need at least 50ft of usb cable...
hey guys, do you know if a disconnect switch will isolate electricity enough that the two contact points are far enough away so that a 16000 volt spark won't jump across it? will a knife switch work?
hey guys, so for my amp project, i need a relay. Problem is, i don't know the pinout, but problem is, parts express didn't put the pinout on their website, and the datasheet wasn't helpful at all.
heres the relay...
hey guys, what drill bit type and size do you guys use to drill your pcbs? The small ones always break, and the big ones are too big, and i can't find any suitable ones.
thanks
hey guys, for one of my projects, i need a hdmi selector switch, but it is very impractical to put like a 20P10T switch. I need help with selecting a readily available for sale chip that will do the job for me.
some specs:
19 pins (hdmi)
about 10 channels
thanks

i am building a HIFI amplfier. the current is gonna be big so I need some solder that will carry at least 4 amp of 100v current efficiently. WIll regular solder work? or is there some...
hey guys, so i'm building a super hifi power amplifier from a chip amp, the harmonic distortion is 0.0003%, and i need a line in mixer. but all the line in mixers they sell in stores are => .01 harmonic distortion. i'm curious if anyone knows a weak hifi chip amp that'll do the job.
thanks!
Hey guys, I made a starter solenoid for my boat cuz im a cheapo. i made it from a push-pull solenoid, and couple brackets and screws. when i start the boat, the 90A of current tack the starter uses welds the cast iron contact points together, making me have to pull the plug on the starter. is...
