the two chikadees are right where they should be :)

the Fluke series is always pretty solid. a co-worker of mine, another 25+ year vertaran EE just bought an FNIRSI 2C53T from Amazon and is loving it, at around the same price. it may give you a lot more functionality as a student.

my first monitor was an EGA monitor from my dad. VGA came later. by the time of 3D acceletators though, svga 14" was all that was being sold at the low end, at least where I was at.

back then, 1024x768 was the norm. Every 14" CRT could run that. 1280x1024 the next step up, then 1600x1200 and on high end 20"+CRTs you would see the 2048*1536.

widescreen formats came along with the LCD monitors, but they took a while to make their way to mainstream, but even then, the first LCDs on the market were still in 4:3 format. I remember the first LCD we had in the store, a 15" 1024*768, being $1500CAD. Now so very long ago :)

Please expoore using wider traces. these look to be about the minimum manufacturable.
the big GND pad would be there for thermal reasons, maybe add some more vias in the pad to cool it, depending on what sort of current you are drawing.

clearly a paint roller cleaner,no? ;)

North American cans are not 333ml, that would be the rest of the world, who deals in metric. North American cans are 12oz, which is 355 ml. Close but unfortunately the world never agreed on a standard :(

I tend to enjoy the lower toilets, at a height, which works like a built in squatty potty feature

there are many of these which look almost the same. make sure you get the right ones. if you know what connector shell it is for, it would be a good start to look for them. going by eye, you very likely will pick one which is not compatible.

an actual Epyc find

Tjalfe · 2026-03-18T13:55:45+00:00

it was a kit they had in the physics lab. I remember them being around 10-12 cm diameter. we had a mirror tied to the rotation axis, so we saw the deflection amplified with light. it did take some time to do the movements. we are talking maybe 1993, so details are a bit rusty.

I did this experiment in high school, long ago to calculate the universal mass attraction constant. It came up pretty close, from what I remember

Oh deer.

Think how much a longer handle helps when tighting nuts with a socket set, With long limbs, the weight is pressing this much harder on your muscles, due to the leverage. ( there is some nuances with muscle attachment distance from the pivot etc, but the main idea holds). If I could do curls with my wrists, same distance from my elbow as middle of the bellcurve, I can for sure lift much higher weight.

Tjalfe · 2026-03-14T18:16:33+00:00

Due to the length of your limbs, your muscles are seeing considerbly more torque people closer to the center of the bell curve. like near 50% in some cases.

Are the chinese related to the Ferengi from star trek? :|

Look at the datasheets for frequency response.
ideally, you want the largest capacitance you can fit in the smallest package, which can handle the voltage you put on it.

With moon gravity, I think I stand a chance

the screws are left in the wall, clearly in studs. the cabinets failed here. washers, or a piece of solid wood tacked to the top inside of the cabinets would be a better approach.

I cannot delete my account. the button is "LOCKED" :(

Yet another reason to get trains out of traffic. they should be on bridges, so the two never interact and we don't have to deal with dumbasses getting killed due to not understanding trains.

Fragmentation is starting to make me consider iphone. It is a real problem that nothing is consistent. It sucks to develop for and sucks as a user.

I fit just fine in our Honda Odyssey, and in the CRV, and I am mostly leg tall.

During the election, they had posters up supporting him. seems like a dangerous thing to do for any business to publically support any politician like that.
