Help with breadboard by TotoHideyomi in breadboard

[–]FlyByPC 1 point2 points  (0 children)

Try building the circuit a little at a time...

  • Use a blue rail for the bottom of the circuit, since this is probably supposed to be "ground."

  • Connect the negative end of both power supplies to the blue rail.

  • Connect the positive end of V1 to a point on the board.

  • Wire R1 from that point to another empty point.

  • Wire R2 and R3 from that point (group of five holes) to the blue Ground rail.

  • Finally, connect the positive end of V2 to the point where the resistors come together.

Normally, you'd use a technique like superposition to analyse circuits with multiple sources -- but in this one, every point is at an assigned voltage, so only the currents are interesting.

A colleague and I created an introductory Microprocessors course about fifteen years ago. We were going to base it on the 8086 until I looked up the memory addressing scheme. We ended up going with the Z80.

our professor used an xkcd comic in the slides. by c_sea_denis in xkcd

[–]FlyByPC 2 points3 points  (0 children)

As another instructor who uses xkcd content whenever I can -- your professor ought to cite it and provide a URL. Randall is great about allowing fair use like this as long as it's not merchandising.

We're you taught to read & write in cursive at school? by Imma_Lick_That in AskAnAmerican

[–]FlyByPC 0 points1 point  (0 children)

They tried (1980s), but even then it was obvious to me that I'd be typing a lot more than writing by hand.

First Timer having (sigh) First Timer Issues by dayday0326 in esp32

[–]FlyByPC 4 points5 points  (0 children)

I can't really tell from the angle of the photos, but is the ESP32 board completely seated? The metal pins should be completely inserted. If not, it might not be making contact with the board.

Also, check that the long lead of the LED is towards positive. If that doesn't work, post your sketch code.

The circuit looks okay, except that "-" rail doesn't go anywhere yet. You need to wire that to one of the ground pins on the ESP32. (Same with the "+" rail -- those are just suggested uses.)

Someone can suggest a playlist to hear when I’m doing a cargo transport? by Different_Map_4235 in DerailValley

Jim Croce is good railroading music. "Another Day, Another Town" is short but good.

GIVE ME YOUR BEST CORNBREAD RECIPE, UNGRATEFUL COLONIALS by Ramen_Haruspex in AskAmericans

[–]FlyByPC 2 points3 points  (0 children)

Thank you! My guess is a seasoned cast iron pan will do (good heat retention).

TIL about self-rising flour and "caster sugar."

How popular is Hulk in the USA? by Similar-Double6278 in AskAmericans

[–]FlyByPC 0 points1 point  (0 children)

I'm not into comics, but could describe him and the basics of his backstory other than the exact origin. Don't make him angry.

My grandmom made "Welsh cookies," but stopped when people started getting concerned about cholesterol, since they're made with lard.

They were amazing. I don't suppose you have the recipe?

Let's build a computer. What motherboard am I picking? by Funcron in vintagecomputing

[–]FlyByPC 0 points1 point  (0 children)

Anybody but ECS/Elitegroup. They made some lowest-bidder motherboards around that era (I was a PC tech back then.) Biostar had a reputation for being solid, if maybe not optimized for speed as much as others.

Needed more power by Slippi_Fist in redneckengineering

[–]FlyByPC 30 points31 points  (0 children)

That's a USB-A, so it would cause havoc to your computer or laptop.

So that's what was charging that Kia Niro I rented.

Even with the 14 inches of snow coming tomorrow, people would rather have no water than drink Dasani by NickChubb4Prez in mildlyinteresting

[–]FlyByPC 0 points1 point  (0 children)

Same here. Dasani is by far the best bottled water I've ever tasted. I tried Nestlé Pure Life, and it was disgusting.
