The edit was before my post, and I saw it also. More likely the host service decided it was getting too much traffic on that photo and disabled it.

Yeah sorry about that, the edit was originally to fix an IMG tag, and it worked.
Google photos must have canned external links.

Photo bucket did the same thing after about a decade, so I guess I have to find something else

Oh dear me

. Yeah bosch it is hahaha thank you sir!

Well, I was curious enough to write an email and AD they say it's a custom part, no datasheet for you.

Looking for any data/equivalent on this primary-side PWM.
Used in a Skynet AKE-9110 (850-911A) SMPS

Thanks for the link, at least that's a little something. It's incredible there isn't a single datasheet to be found on the internet for this part number.

After looking around a little, current mode PWMs with similar pinouts to SK-8060 are:

UC384x family. (Unitrode/Texas Instruments)
ISL684x family. (Intersil/Renesas)
TSM007 (ST)
NCP1252 (ONsemi. Funnily this one uses an external resistor only to set oscillator frequency. Other than that the schematic on the datasheet looks very similar to the one in your link.)

Found inside a TomTom Go Live. Any ideas?

frozenfrogz · « **Reply #1285 on:** March 17, 2018, 09:56:50 am »

Since there is a QR code - why not give that a shot?

jitter · « **Reply #1286 on:** March 17, 2018, 10:21:34 am »

I don't have anything that will scan such a small QR-code.

frozenfrogz · « **Reply #1287 on:** March 17, 2018, 10:58:23 am »

Take a close up photo and enhance the contrast with Irfanview or the photo processor of your choice. If you don’t have a mobile app, there are some web services where you can upload a picture to decode.
https://webqr.com/ for example.

jitter · « **Reply #1288 on:** March 17, 2018, 12:56:53 pm »

Thanks for the link, I tried a photo and the image from a USB microscope, but to no avail. Enhancing contrast and some other tricks don't seem to help.

frozenfrogz · « **Reply #1289 on:** March 17, 2018, 12:58:41 pm »

Mind sharing the pic here? Maybe someone else can decipher it

jitter · « **Reply #1290 on:** March 17, 2018, 01:17:42 pm »

OK,

is the link to the image straight from the USB microscope. It's as good as I can get it (yeah, it's a crappy microscope). I need to keep the camera/microscope at an angle, otherwise it's totally invisible.
It looks like a DataMatrix code, so I tried a perfectly legible DataMatrix serial number sticker that I know a Zebra Symbol scanner has absolutely no problems scanning, but the decoder just says "error decoding QR Code" on that one too. Another online scanner does recognize that code, but still not the one on the IC.

Edit: I tweaked the image a little more, put it through this online decoder and it's indeed a DataMatrix code, it says this: 2730907261P01
No hits on google, so back to square one.

Barometric pressure sensor, probably used there in combination with the GPS height info and the map data on elevation to give a weather forecast.

jitter · « **Reply #1292 on:** March 17, 2018, 04:39:27 pm »

Yes! That's it, thanks!
To be more specific, it is the SCP1000-D01.

I didn't expect to find this in a car satnav, if it had been in my Garmin outdoor satnav, OTOH...
Since the barcode on this one looks slightly different, I'm thinking they laser engrave the ICs with a barcode rather than the normal markings (lot trace codes, datecodes, etc.). Or maybe even a serial number?

shakalnokturn · « **Reply #1293 on:** March 19, 2018, 10:33:58 pm »

Anyone know what this one is?

amyk · « **Reply #1294 on:** March 20, 2018, 02:55:50 am »

CLC522AJE.

OK, this is from the film War Games so maybe it isn't even real, but it looks like something that might have been real for a short period of time during the 1960s. An input device that allows the user to select an alpha-numeric digit by clicking through them, with some sort of code output. Seen these has decimal and hex code switches, but not as full alpha numeric with 36 options. Is it fake, real, or just really rare? Or maybe I am being fooled into thinking this is user-selectable and it is not.

Digikey sells similar devices, numeric or hex only: https://www.digikey.com/products/en/switches/thumbwheel-switches/214

So far as the movie prop itself goes, I doubt it. There's no actual requirement for the whole alphabet to be there in the movie. The switches look real (I've seen better pictures than yours), and they likely used one of the more common 8, 10, or 16 position dual push-button switches much like those that are still obtainable today. Prop departments surely have people who can re-label the code wheels to any symbols required. Or the switch manufacturer will do it, if you pay them enough for a special order.

Looking at history, the Enigma machine is the one that comes to mind first, since those pictures are easy to find.
As for real cold war hardware, if our military wanted such a switch, getting someone to make and sell them with the required number of positions was merely a detail with a price tag on it.

And I haven't looked very hard at all, but this looks interesting: https://www.hartmann-codier.com/products/rotary-code-switches/dh5/

I'm trying to find some information about the following connectors.

This is the male header:

This is the mating female connector:

It is 15 pins. The pin pitch, as accurately as I could measure, appears to be 3mm. Both are through-hole mounted. The vertically-oriented male connector is approximately 32x12mm.

I've done a bit of searching but I've not found anything yet. I'm not even sure how you would classify this kind of connector. Board-to-board? Backplane? I'm specifically looking for the female mating connector, in either right-angle (as pictured) or vertical mounting.

I inherited a bunch of discrete components from my father in law recently. Many very interesting bits from the 50’s and 60’s (I think) that are in superb condition, but this set of semi-conductors (I assume they are) has me flummoxed! Does anybody have any idea what they are?

They look like a two-lead TO-92 package with color code bars on both sides. There is nothing printed on the top or bottom. I’ve put 750v dc across them and they won’t blow or conduct any current.

Thoughts?

GomezAddams · « **Reply #1299 on:** April 11, 2018, 03:59:35 am »

Ah futz! I had tested several of these and couldn't get them to respond. Now I've run the rest through a component tester and they appear to be diodes with a forward voltage of 675 mV and reverse current of 6 nA. That's a pretty simple answer if correct. Maybe the first ones I tested really were blown already?
