so apparently you can increase the capacitance of an electrolytic capacitor by putting it in a centrifuge? weird!
so apparently you can increase the capacitance of an electrolytic capacitor by putting it in a centrifuge? weird! does this mean we'll get Altera back again? https://www.networkworld.com/article/957338/intel-plans-spinoff-of-fpga-unit.html @tubetime Getting out of the ARM business once again. I wonder how long it will last this time. @tubetime interesting, though I don’t get why you’d buy a company and then put it out on its own. @tubetime spin off the FPGA unit? Spin off? Like in a Cyclone? I'll get my coat 🧥 one of the pins fell off so I carved away part of the encapsulation and soldered it back on @tubetime That power supply definitely looks like stick of C-4 that some hero cop (recently recalled from retirement to save the day) is trying to disarm in a movie from ~the early 00s. Just sayin'

@tubetime @awlnx The captain also wrote a book about this flight that is a very interesting read: https://play.google.com/store/books/details?id=mbDl7plG7RMC @tubetime Thanks for sharing this — I had to read it in two sessions (with a commercial jet flight between!) but this was a great read @tubetime Great show, the audience gets to play Guess The Failure Mode from the comfort of home. "I can Guess The Failure Mode in 5 minutes Alec! " bookmark this: https://connectorbook.com/ it is not just a book--there is an online utility that can help you identify mystery connectors!

@tubetime Am I the only one concerned with that it appears a GIF viewer is used as interface to a SCADA system? @tubetime it's got thicc scroll bars though - very user friendly to be able to see the current position in the document. this is almost physically painful for me to look at, so I'm sharing it with the rest of you, too. i've reverse engineered a printed circuit board using ARTWORK FROM AN ALBUM COVER. 😲 not on my list for 2023!!

@tubetime the Noise of Art and not The Art of Noise? https://en.m.wikipedia.org/wiki/Art_of_Noise @tubetime is that an art of noise album? Or someone copying the style with the ds3? i'm trying to install OS/2 2.0 on my Thinkpad 700C (16 floppy disks, wow) but i'm running into this weird error message. anyone recognize it?

found this https://web.archive.org/web/20140912083725/https://ps-2.kev009.com/pcpartnerinfo/ctstips/252a.htm which says i need to copy some files over from the reference disk. hmmmmmm @tubetime I think that's the error that gets thrown when there's a Prime Directive violation. OS/2 2.0 is a pre-Warp civilization 😛

@tubetime Allegro (and Cadence? Schematic capture) was my first tool for making professional PCBs. It was what Sun used for hardware design. Eventually learned Eagle so that we could do more in our department "under the radar". Our Allegro "tape out" had to go through a PCB department and generally had long delays whenever hotter projects had priority.

@tubetime Impressive that it can manage to be both wildly distasteful and anti-competitive. @tubetime I’m fascinated by some of the specifics in this ad. They had just moved to AZ (from NY). The logo (there’s an extra notch in the m) and the device they’re advertising doesn’t exist. To my knowledge, this is pre-PIC16. hey, quick reminder that i'm also on Bluesky. @tubetime.bsky.social. should i migrate over? i don't use twitter anymore, and mastodon doesn't have many non-techy folks.

@tubetime What non-techy things are you interested in? And no, a site run by a good friend of and supporter of Elon that Elon is invested in really isn't it. It might be ok now but how many corporate communities in the last couple of years have absolutely turned on their residents? Etsy, Bandcamp? The implosion of Tumblr? And also I would miss you. IDK I've found a lot of non tech people here. It's important to follow a lot of people here to get a real sense of what's going on. But, yeah, what sort of things are you looking for? @tubetime Did you see how some memory modules were constructed? I would hate to have to deal with these rope memory modules in any way, shape, or form... That said I had an old mini-mainframe things 30 years back that actually had a few cards of plane ferrite core memory and it used to dim the lights in my place when it turned on, and then again when loading/reading the memory. Quite surreal... took this hard drive out of my IBM PS/2 to measure the edge connector and noticed I hadn't cleaned up all the corrosion when I recapped it a while back. oops yeah looks like a broken trace. that might explain why the drive doesn't work half the time An historic hangar burns down 😥 https://mastodon.nz/@labradorgirl/111372862948585013 (photo from Wikipedia) this is the same type of hangar at Moffett Field. the hard hat was required because pieces of wood randomly fall down from the roof (!) @tubetime I can see the two hangers from my neighborhood, regularly shop near them (as in, drive by about 100 meters away from the still-standing end) —and they are magnificent. I don’t believe either of them had been in use for a long time, and I’m not surprised it reached the stage of dereliction and incongruity where this was nearly inevitable. I’m sure it’s not just Southern California, but large historic structures that stand in the way of some other land use have a habit of burning… @tubetime I'm doing a more thorough reverse engineering of the power PCB from the Thinkpad 700 series. lots of work so far and there are still more parts to remove on the other side of the board!

that's both sides. phew, lots of work! the next step is to photograph the top and bottom sides of the PCB. I really ought to get a scanner. 😅 |
@tubetime don't like that
@tubetime
It's pretty clear (and he acknowledges near the end) that any effect is probably due to mechanical deformation.
It would have been simpler just to measure continuously while crushing one in a vice.
