I don't want to be human! I want to see gamma rays, I want to hear X-rays, and I want to smell dark matter ...
I want to reach out with something other than these prehensile paws and feel the solar wind of a supernova flowing over me.

LOL - he opened mine! The Chinese metal detector!

I need to go to that thread and congratulate the member who finally guessed it. Hopefully he will tear it town and probe it.  :-/O

Please sacrifice the thing for science.  :clap:

That's the intention.
I have something else already for next Tuesday though.

I'm pretty sure the little paper strips are intended to be used as page markers in books/manuals. I used to use the Scotch version of those back in the 90s when I saw something interesting in a textbook or manual. Some of my older manuals have lots of yellow "frills" on them!

Those blinker are fairly complex because it can most likely to detect a bad light bulb. When the current drawn is less that a set value (a bulb is bad) it will stop flashing. It will stay always on. It is very similar to the one from our family Toyota Corola (1974 model).

That mechanical blinker... Love the old-school mechanics!

Love how the Clamshell pack opener was in a Clamshell pack.. Those bastards!

Think I found the schematic for those little hybrid/IC/whatever things in the blinker module.

K224GG2 (?224??2)

Some sort of timer perhaps? Wish there were some labeling in the schematic.

"?224??2"... forum software, you win again...

I find that the vast majority of these "annoying" packages can be defeated with a sharp knife.

Typically to machine or engrave on a curved surface like the pen you would draw the design in the normal flat manner and "wrap" the design around the workpiece with CAM software. The Cam software will generate the linear and rotary toolpaths. The workpiece would be mounted into a rotary indexing head mounted on the linear axes. With two rotary axes  connected at 90 degrees it is possible to engrave onto a spherical surface.

I suspect the Lada flasher relay is not the normal thermal bimetalic type coz it gets bloody cold in parts of the former USSR.  So cold in fact an old trick to starting an engine is to light a fire under the engine sump to heat the oil to the point where it will actually flow allowing the engine to turn over.

Got to love the irony of the clamshell package opener packaged in a clamshell package.

What is the point Tinhead, your forum opus on the tekway tells it all LOL.
Checked out the photos. Some amazing cable management going on in some photos. I also love the ultimate multilayer PCB from the Audi fuse panel just to prove the Russians did not have a monopoly on clunky design. The site is well worth a look and the guy is clearly a decent photographer giving justice to some of the exellent workmanship.

I like opening up old stuff too. I'd love to have the enclosures from some of that old Russian hardware so I can repurpose it into other things (synths/audio stuff mostly).
It's funny to see those pins with wires spiraled around them instead of solder.
Old Furuno marine equipment is amazingly jam packed with through hole stuff and is built like a brick. I even found a 512K-BIT UV erasable memory chip in a Loran-C from the 90s.

Complaining about the people who make clamshells and blister packs when receiving free products from a company that makes that packaging was hilarious :)

I believe that these low integration hybrid modules on the calculator board are not so unique as it's essentially Soviet implementation of IBM's Solid Logic Technology. I remember that 20 or so years ago these used to be on display in National Technical Museum in Prague with description of the manufacturing process used which is essentially same as is described in IBM's SLT materials, ie. multiple ceramic thick film hybrid dies stacked in one package, all connected to same external pins on sides.

I liked the "redneck PSU Brick replacement." stuck to the back of the computer monitor. O0

That's wire-wrap, and when done right, it's surprisingly durable.

Oh, and Dave, those multicolored things with the blades are, I think, envelope openers.  I imagine quite useful if you have to open a lot of envelopes...

BTW, most of that swag is why I'm not in marketing.  What on earth could possess someone to think that most of that was a good idea...

Seconding. I don't think I've ever heard "indicator light" anywhere in the States. Turn signal, yeah. Blinker is also very common.

Haven't heard anyone called a mug though.

"Flashers" is also something we call them here in the states.  "Indicator light" is used in the auto manuals and DMV booklets and that's about it.

We don't call people mugs, but we call their faces mugs. :)
