Second hand, lots of people sell them when new models come out, there's like a dozen.

I bought a bunch of asic/soc boards and i got a pineapple pi too somehow...

Ah, that works.

Here $30 is the cheapest I've seen a 3b sell for.

WOW that is BS, people are selling SD cards with free rom images for 100-200 again.

Are people still that dumb?

*shakes magic 8 ball and notices warning label telling me not to break it open and drink the contents*
Yes.

*signs point to yes

Huh, I just learned there are two conflicting pinouts for TRRS plug headsets- ground on the 2nd ring and mic on the sleeve, and mic on the 2nd ring and ground on the sleeve. I thought it woud have been the latter as the common one, but best I can tell it's actually the former.

My launch revision playstation (PSX, SCPH-1001, PU-7 motherboard) just started having intermittent disc read failures again (this happened around two years ago, too), and I fixed it by once again doing the same thing I did last time it did this; reflowed solder to all the fuses on the bottom left corner of the PCB as well as the capacitors in the same corner.

Just played it for five hours without problems. :|

I probably broke something loose from the PCB when I transferred the system to a new top shell half. The screw posts had broken away on the original years ago and so I'd had to hot glue the top of the shell down, which requires a lot of force to pull back apart and exacerbated the problem.

The original top of the shell was super brittle and breaking into three pieces. The new one is from a -9001 model which i cannibalized for the CD drive and power supply, so I had to cut into it quite drastically to make it fit. Later revisions rotated the drive orientation.

Note the missing parallel port hole on the new shell top, and the massive chop taken out of the back for the RCA jacks
…if anyone has a non-brittle/yellowed -1000, -1001, 1002, or Japanese -3000 shell (I just need one with the RCA jacks on the back) floating around, please consider PMing me. A complete unit would be cool, too; I don't mind if it works or not.
I never see launch units for sale around here because they all had terrible drives when they were manufactured and most were probably trashed decades ago. The one I have is the only one I've ever seen. I pulled a donor drive from a later revision console.

Maybe I should try that (reflow thing) on my -5501 (PU-18 motherboard) as well, since it's got a similar but slightly different problem sometimes.

My -1001 has had so many janky fixes applied over the years that it's kind of terrifying to look at, but it's actually become my most dependable model when it comes to reading discs properly.

Bonus: vintage CPU's and other old chips of mine

I have four more atari 2600 CPU's (6507's) than I have uses for. Too bad the 6507 has no IRQ line.
The NEC V20 is actually nice, though.

Quite impressed with the comfort and sound quality if my headphones, though I ought to be for the price point. I had to use the dumb Bose Connect app to configure the button that changes noise cancelling level, and make the annoying as fuck voice prompts stop though. And inexplicably, that app requires location permission and location on to run.
Installed it on my old phone, fired up a GPS spoofer and directed it to McMurdo Station, then cut wifi and started the Bose app + setup the headphones. If data did leak to coporate, some engineer can scratch their head at it.
But seriously, that shit pisses me off so much. Bothe needing the app, and the app needing uneeded things. I didn't even do anything to the button in the app, it just made me connect at least once to make it work instead of nagging me. If the app hadn't worked on android 6, I likely would have returned the headphones, or pestered Bose until they fixed them.

Aaand this is why I never buy anything new anymore. IoT is a disease.

I'm at the hentai tech forum.
I wonder if there are threads about how to build AI/robots.
Wait, isn't "What is the last thing you thought?" supposed to be in another category?

It is just a cheap board plus compiled tensorflow/torch. I'm sure if one asks there are at least a dozen users here with experience in both.

I have at least compiled tensorflow/torch

As for cheap boards that run it well, not so much, but I have still got experience with building it (which is kind of painful sometimes - Cross compiled especially).

It's in almost all categories, albeit sometimes in a different name (IMG:[invalid] style_emoticons/default/rolleyes.gif)

If the tax man asks, then my ultra high end PC is for AI research / data analytics.

I unplugged my headphones from charging last night (pity they made the decision to disable BT and noise cancelling when charging- they still work as passive normal cans though) and noticed they auto connected when I turned them on. That part seems normal except they connected to my gaming PC and phone. Audio worked from either, and both devices confirmed the connection. I didn't having sound from both sources though.

Not sure what the deal with that is, but I'll have to explicity disconnect my phone before gaming so texts and emails don't pester me.


btw, dragontamer8740, I tend to find your project posts quite intersting even though I don't usually have any noteworthy commentary on them.

At least I'm not just posting into the void, then :)

Have some gore from inside my most reliable playstation.
Replacement 5 amp surface mounted fuse, some through hole caps replacing smd ones, built-in decoupling capacitors on the RGB lines by lifting the encoder pins and hooking components to them. Hot glue to stop from torquing the pins off the chip while placing. I was low on good project wire so I just used more glue blobs as bumpers to stop the uninsulated leads from shorting on anything.
Also one wire going back for the S-video luminance line, since that was borked on this board.
Also also a PSNee modchip (open-source modchip for AVR's).
Fun fact I've probably said already: This is an unusual playstation revision in that it (and other early ones; only the very earliest in the US) uses dual-ported VRAM instead of Synchronous Graphics RAM (SGRAM). It's closer to the design of the development units than probably 90-95% of the retail units in north america. Since it launched about two years earlier in Japan, it isn't quite as unusual there. But they launched here in late September of '95 and by early '96 they were apparently already using SGRAM. Mine has part codes from October of '95 on it (the GPU - IC203, CXD8514Q - is week 40; October 2-8), but I think the CPU might have an April '96 part code, so sometime after April is probably when they switched. It could also have just depended on supply at individual plants, though.

Modded the board a little bit so I could use a later model PSU on the early board (they have different pinouts and pin counts).

Can't show in a still image, but it pretty much never skips in FMV's.

Smoke detectors can't be "reset" after tripping, can they? That is, their "fuse" or whatever is a one-time deal, right?

Had a frying mishap today (not a grease fire; just burned potatoes) and set one off. Assuming I need to just buy a new one. Haven't tried plugging it back in yet because I don't want to annoy my roommate if my suspicions are correct.

No, there's no fuse or anything in smoke detectors. some types of cable based heat detectors may require the cable be serviced, but the self contained ones and combination smoke/heat ones don't.
The smoke will keep alarming for a bit because there's still some smoke in the sensor. Depending on the type, it either measure smoke's increased ability to be ionized or to scatter infared light. The sensor can become fouled and depending on how smart the logic is will either compensate for dust buildup or gradually get more sensitive to false trips. That's mainly a concern for dust buildup though- if enough greasy/sooty smoke or heat got at the sensor to foul it, you're gonna have collatoral damages.

Source: I'm licensed to work on fire alarm systems in my state. I still have a few cans of 'smoke' and a heat gun around somewhere...
I once used the heat gun on the end of 20' of pipe because the fire marshal decided the one at the top of the elevator shaft needed testing during the inspection.

Danke.
I plugged it back in after around 12 hours and it's good now.
You seem to lead an interesting life.

My dumbest story, I was in a multi level corporate building and the fire alarms had been deactivated due to being serviced/repaired and they forgot to rearm the system. Well... there was a fire in one of the kitchens on one level and huge amount of smoke and people were just sitting around ignoring it. It took a lot of convincing to start organizing people to leave the building because 'if there is no smoke alarm then there is no fire" even though people were starting to cough from the smoke.
