instead of a fluke 101 multimeter, you can get pranarom - aromaforce oregano mini-caps. basically the same thing. they are easy to swallow!

any firefox/linux wizard around? since a few days ago, when trying to drag tabs out of the main window to put them elsewhere, they become ghostly and unselectable. initially this happened when i had something else in full screen, but now it happens under any condition www.youtube.com/watch?v=dHm-...

merisky, for when you want to be ESD safe, but not too safe

lead free solder, you pay for the tin, the lead is free!

huh! i didn't expect to see an FPGA in a mid range AV receiver (yamaha rxv4a)

does anyone off the top of their head know how to calculate filter caps for a linear power supply to get a specific ripple voltage? i needed this today and learned that i had already forgotten how to do it and had to google it. i'm curious if anyone keeps it in their mind

does anyone know what's the name for this type of enclosure and where to find them? i've been looking for a sloped box for a project, but no luck, they all have a very long sloped face, but i want something like this thing. thank you!

my sweet boy, coco, performing the most important task: being wonderful

i don't understand how this makes sense statistically. i'm playing the same, or it feels like the same, but every once in a while, after i reach a new high, the next few days i'm dragged down like 200 points, and i am not tilted. i'm playing calmly, but am outplayed consistently. then it normalises

youtube defaulting to the bullshit robot dub for every video sucks so much. there should be an option to have it default to the original language, it's my problem if i understand it or not. don't force a language on me!

finally found what looks like real TL082s out there: the rising edge is quite wonky and the transitions are as well, so, maybe this is a rejected real one that didn't pass QC or something? whatever this is, it's much more usable than the crappy stuff i had before: bsky.app/profile/anth...

there are fucking nazis on chess.com for over a year now! not banned!

so i'm working on an Fm transmitter and receiver for this semester's project. i've made two antennas and tuned them with the help of the nanoVNA, which show them to be quite usable, individually, but when i connect both antennas to the VNA, to see S11 and S21 frequency shifts, and i have no idea why

a new job rejection rolls in. at this rate i'm going to end up living under a bridge soon!

i made a little stand thingy for the nanoVNA. i thought making a stand for it would be too hard, but i was cutting wire for an antenna and i had this little idea. pretty happy with this silly little thing

this is not what is expected from a TL082 op amp, right? the slew rate is ~0.5V/us. set up with a gain of 10 i should expect to see about 17dB at around 300KHz with a TL082, right?. this isn't even close, yay only having access to counterfeit everything in this hellhole!

what is this the logo of? i'm sure i've seen it before, but not sure where. in this ocasion it is shown in the song Primer: www.youtube.com/watch?v=6Dif... attached image is from it being played on my scope. the original doesn't have this visible all at once in the same frame

it's been so long since i do anything electronics related just for fun. we've been needing dual supplies for class a lot lately, for op-amp stuff, and i got tired of cobbling together a virtual ground split supply on a breadboard every time, so i looked through my parts bin and made this for 0$

the true face of meow

damn! tp link routers don't shut up!

so i got this scam email, but the scammer failed to disguise the, whatever it's called, service? used to spam people, and it is sendgrid. i looked at the email header, and thought to report it to sendgrid, but, how do i clean the header so no identifiable info is there? i have no idea what most 1/n

there's a weird 8 in my room

i had not said anything cause i felt it may have been a premature celebration, but i've been ocasionally testing it, turning it on and leaving it on for hours, running self cal and self test on it, and after a lot of that, i think i can safely say my scope lives again! (hopefully it stays like that)

i always find it so amusing to see that my computer, in a way, experiences time dilation like this:

Hey Everyone! Here is a free giant 97-page document on #FPGA. Share with your friends that want to learn or be introduced 😀 files.digilent.com/reference/Fi...

is gigabit internet a waste of money? our isp upgraded us to gigabit, and so far the only thing that gets that fast is speed testing, and the odd linux iso download. I'm downloading guild wars 2, which is like 70GB, and it goes at a glacial pace worthy of the early 2000's

what's the deal with ai slop like this showing up all over the electronics feed? this account mostly posts crappy ai images with a paragraph saying stuff that could make sense, but nothing else, i don't get what they're hoping to achieve with that stuff

why is the vivado download so damn slow and so cpu intensive? good lord

does anyone recognize this species?

"auto dubbed". fuck off with that! if i wanted to hear a robot speaking my language i'd only accept "your word is my command"

does anyone own a TP-link archer AX55 router? i have some questiosn about its VPN capabilities and there doesn't seem to be much info about it online

A perfectly sensible setup for doing perfectly sensible things.

Looks like a sawtooth wave right? But this one is special! I designed the chip that creates it! Let's dig into how it works.

Very proud to be the original creator of this #FPGA meme

I thought I was coming down with something and took a test. Looks like I'm just feeling a little flat.

and they say RF isn't pure magic www.youtube.com/watch?v=rVJw...

this showing up under electronics did me a bit of a confuse. i was like "wwhy is a PCB person dressed all sporty?" lol

great, now the scammer bullshit from twitter is getting here

found my first ever diy switched-mode power supply, an MC34063 supplying the 13v needed to get PICs into program mode or something, the top side is ridiculous, but i cringed when i saw the bottom side still pretty proud of l'arc de induction. first time seeing it on the scope!

this power estimate for lighting up some LEDs with an doesn't make sense to me. how is an io pin using almost 2W, at 3.3V and 12mA? that would be 39.6mW at most, no? am i interpreting this power utilization chart correctly?

a full adder! guess i had to start with the very basics! (weird that the 7 segment display is dimly on tho)

first FPGA adventure outside loading pre-made projects is not going great! 🤡

on my 13 reasons why tapes, 6 of them will be dedicated to summer, heat waves, the sun, oil companies, heat sensing cells that don't activate only when temperature is dangerous, and the fact that it is physically possible for matter to be hotter than 21°C

what's with random meme/animals accounts following people? o.o

who else still uses sudo when running a cron job from root's crontab for that extra superuserness? and what is the overlap with those who uset apt-get instead of just apt to make sure apt knows you mean business?

so, what's going on here? bluesky posting about moderation changes, and everyone asking for an apology and mocking their posts. what happened? i am not that much on this site, so no idea what's going on, but people saying "your site is on fire" will this platform last? again, what happened? o.o

another attempt at copper diodes. today i tried just quickly immersing the caps in water 10 seconds after they started glowing pinkish orange in the torch fire. this looks promising. the oxide layer flakes off easily, so i'll test after figuring out how to softly probe the oxide
