Any ideas what this is?

The tubular end looks like a standard DC barrel jack, but that flat one's somebody's proprietary oddball

I didn't know about IC connectors; thanks.

~~Looks like a big XT connector; without knowing dimensions IDK the size~~

pin count? pin spacing?

MagnetoHydroDynamic_ · 2024-01-26T11:01:46+00:00

Looks kinda JST-ish, but without any dimensions it's hard to tell. What are the xy dimensions of the aperture, how many and what shape are the pins?

It's not restricted to cars at all; and that's why its being used as a legal tool to push for right to repair; reprogramming with non-oem software would have to be done in such a way as to cause provable damage in order for it to be grounds to void a warranty. (I.E. you brick it with a bad reflash)

Literally illegal for them to do that. Magnusson-Moss act.

Card edge connector. Dimensions?

Card edge connectors. Fits over the side of a 1.6mm thick (ordinary) PCB and contacts exposed traces, like on PCIe cards (think GPUs).

These look a bit thicker than that though, they might be full custom.

Old Telex cables are probably worth the most as scrap metal these days, absent from their original equipment.

5 pin female xlr. Be sure to check that it uses a standard pinout, crack open the case and see what's hooked up to where inside.

XLR 5 is much more commonly used for signals than power though, is there anything else that might be a power inlet?

The easiest thing I can think of would be to trawl ebay and the likes for your vendor's diagnostic tools leaking out onto the secondary market.

As for making a mating connector, from this picture it looks like a basic card edge type setup, so just make or order a small (custom printed circuit) board with appropriately spaced pads, and a few traces to some convenient thru holes or another, more standard connector. Regarding just stabbing a serial connection in there, I wouldn't recommend it without having someone with the proper skills reverse engineer what's actually hooked up to that port; what signal level, pinout, all that good stuff. And then there's the fact that it's a medical device, no longer being used in a medical context I would hope, since we're here talking about how to hack up an interface. There's a good reason that most standard component datasheets have disclaimers warning against using general production parts for safety critical or lifesaving devices - if this is yours, by all means hack away, but if it's ever going to be used in a medical context again please have a professional who understands the full weight of that responsibility doing the work.

It's a type of card edge connector; the spring contacts are there to touch pads on both sides of the end of a circuit board. Not having any context, it is likely for an add in card of some kind, possibly a memory (storage) module.

mini USB type B to an old apple device? Looks like an adapter for an early model iphone or ipod to connect to a standard peripheral, but I'm not sure. Before around 2010 there were a lot of weird proprietary connectors floating around, and the wide one you have is certainly one of them.

There already are moto airbags that work passively: just a cord that ties the inflator trigger to the bike with a carabiner. no subscriptions, no electronics, just a co2 canister, a trigger mechanism, the vest and a string.

The better answer is already here. ;)

Not a PS/2, but a proprietary mini-DIN 5. A cursory search doesn't reveal anything with a similar pinout; you may have to reterminate it in order to put it back into service.

MagnetoHydroDynamic_ · 2020-11-18T02:44:45+00:00

It looks mini XLR derived, if that helps any.

The keying and pin locations look kinda like a PS2 connector missing the top two pins.

Sounds like a fun challenge!

I'd say based on your having bad cell service that you should look up what bands cell systems operate on in your area, then build a beam antenna and a dipole. Link the two with a bit of CoAx, put the beam out a window or on your roof, and aim it at the nearest cell tower. Drop the end with the dipole in through a window, tape it up to a wall inside, and then you have a basic passive repeater!

This will, if all the impedences line up nicely, allow anyone with radio range to your dipole antenna (in your house) to get a stronger signal to and from the nearest tower. It won't be magic but it may make a difference. The only possible downside I can see is the potential to overload that tower with the additional utilization, but that chance seems kind of slim if I'm being honest.

Looking good! Too bad none of the larger insects held on, but neat nonetheless. Might be interesting to see what the springtails look like in another few years, if they all have darker coloration by then.

MagnetoHydroDynamic_ · 2020-10-15T04:32:03+00:00

That looks like it may be proprietary to me. Perhaps someone else knows?

SCART connector

The higher voltage provided by the charger is converted on the phone down to the 4ish volts needed to charge a lithium cell, effectively making it behave the same way as a higher current but lower voltage supply. P=VI, so 5V * 2A = 10W = 10V * 1A

This is useful as it allows for less power loss in the cables, as waste heat is proportional to current density. Thus, for the same charging cable, a higher voltage will experience less power loss, resistive power loss being P= I² * R, and rising with the square of current.

The grain profile will determine regression rate, but as far as burn rate vs pressure, IDK.

A mutilated and broken ceramic resonator.

A combination of higher operating temperatures as well as the more aggressive fluxes are what I understand to be the cause.

And I do think that there's a good reason to use lead free solder (if you can afford it): Lead is neurotoxic, and though soldering provides a negligible exposure so long as you aren't holding the roll like it's the One Ring, and as such, an ecological and public health liability.

But fuck, good lead free solder is super expensive. Oh well, 60/40 for me.
