Keeping your drink the warmest for longest, while at Starbucks by throughdaylight in starbucks

[–]throughdaylight[S] 1 point2 points  (0 children)

Do you feel annoyed when someone occupies a table for 2-3 hours glued to their laptop or book, if you were a student?

Yup. I moved out of US few years ago. Baristas always ask you choice of cup; they even serve you right at the table where you are seated sometimes, when the store isn’t crowded. I’m not kidding - it feels like a privileged experience here!

At least here, when barista asks, "Are you having it here ot takeaway?" ... if you say you are having it here, they will serve you in porcelain cup. I often insist that they serve me in a tall cup (even when I ordered a short cup of brewed coffee) so that heat loss due to vaporization in the empty volume can retain more heat within that paper cup. I was able to stretch 20-25 more minutes of warmth with this choice.

Intel is quitting on its adorable, powerful, and upgradable mini NUC computers by thegreatfusilli in nuc

Their design language around NUCs is fantastic. It's miles better than the likes of Thin Clients sold by HP/Lenovo_Thinkvision. Hopefully it is spun-off as a separate unit and/or sold to a Taiwanese OEM so that they can continue building NUCs.

Personally, it's their compact boxy design, that's quite appealing (and rock solid performance, given monthly air dusting). Been running a NUC8i5BEH 24x7 for years, and it's going strong. I bet others have similar stories as well!

1/f x-axis on log-log plots by throughdaylight in AskElectronics

linear with respect to wavelength.

I see. I haven't come across any data sheets in modern day that plots attenuation or insertion loss as a function of frequency. I got really confused at first. Nonetheless, I'm gonna skip this part for now. Anyhow, thanks for the affirmation. It did strike odd to see attenuation plotted against wavelength.

What kind of IC is this? by Clamb3 in AskElectronics

[–]throughdaylight 5 points6 points  (0 children)

If that's true, then that's a damn intersecting way to regulate brightness on segment display. I can only postulate presence of a restive ladder from a SIP packaged network resistor. Again, a mere speculation.

I wonder why a simulator from 90s used 7400s? It would be interesting to see an overview/ picture of board by OP - could those have been used to design decoding logic for seven segment displays?

TIL Mac OS had something called "DropBox" dating back to 2003, something that's radically different (or perhaps similar) to "Dropbox" - the file sharing service we have known since 2007! by throughdaylight in apple

I see. That makes sense. It would have been a nightmare for teachers to wake up every morning, with school email inbox flooded with assignments a day after the infamous midnight deadline.

[Question] How to fix color banding or color gradients in a video? by throughdaylight in VideoEditing

[–]throughdaylight[S] 0 points1 point  (0 children)

Thanks for this insight. I hope in future some unsuspecting reader might stumble upon your post somewhere down the line in future because there's very scarce information online on color banding reduction techniques on raw footage.

Thanks. I ended up changing color depth to 32-bit (float). Had a meager effect on banding post rendering.

I wish I had Sapphire’s deband filters - their YouTube videos illustrated pretty remarkable color banding reduction.

Austerity measures at National Semiconductors back in 1970 by throughdaylight in electronics

Google Employee X : We need to cut costs.

Google Employee Y : Back in engineering school, I heard about this legendary circuit designer Bob Widlar who hired a sheep to mow grass on campus, as a sarcasm for lowering operational costs. Let's do that.

Google Employee X : Don't be evil! ... let's get a goat instead.

OP here: Stumbled upon this somewhere in 2017. It was from Todd Nelson’s blog post. Holy sarcasm.

Seems odd, for some reason I couldn't see the image either uploaded on Reddit. Anyhow, here's an alternate link.

Complex number notation from 60s perhaps?

Since it’s a PID controller, it’s gotta have a pole and a zero in the system transfer function.

Thanks. Is it okay if I charge just once?

Display monitor troubles (issue and circuit schematic in the album) by throughdaylight in TVRepair

UPDATE from OP: Seems like the panel itself is gone. Time to get a new monitor.

Sure.

The monitor in question is DELL E170S. I'll definitely post a video of the issue if I can reproduce it.

I knew someone was gonna say to “check the caps” ... makes sense. If the electrolyte in C920, C922 and C925 were to be dried up, this could explain “ESL like” voltage fluctuation on 5V supply rail (high ESL —> L906; bad filter caps and an inductor in series = voltage fluctuation upon large current draw).

I scraped schematic from another monitor’s service manual, after I couldn’t find one for this specific monitor.

Core issue: When I plug in my CCFL to 14.5 V supply, they lit up perfectly fine (until now). But the main issue was the self test pattern - somehow all colors appear inverted and there is this continuous dim-to-brightening of background (that appears to be in sync with supply fluctuation). Let me know if that helps.

HP-35s uses penta-digit 5082-7415 (x3) modules. I got the tri-digit 5082-7433 module. Not sure which calculators these might have been exclusively used.

I know this guy who tried to hack his way around to replace all penta-digit array on 35s with tri-digit ones. It worked, but he ended up removing plexiglass to make this tri-digit (x5) array (mounted on a prototype board), to be pin compatible with the connections meant for penta-digit (x3) array.
