I was the lead engineer on the navigation units of the mice developed from the beginning of the program in 1997 until I quit in 2005. That 8 pin part was either Iron Mouse or Copper Mouse. It was a front end imager/dsp that was connected to a customer supplied processor via SPI. The product was unnamed when I started developing it so I called it Front End Mouse which became Fe Mouse or Iron Mouse. The actual design work was done in Malaysia. I didn't recognize the wafer (I know most by sight) and think that it's a copper or iron mouse wafer.
It would be cool perhaps to probe this thing and see if it’s functional. Maybe a crowdsourced reproduction project to get this diced up and mounted? Surely there are still some small run packaging providers that could do that?
Microsoft most certainly did NOT make the world's first optical mouse. They were first created ca. 1980, both at MIT and Xerox PARC (different designs). The MIT design required a special mouse pad and was used with early Sun workstations, while the Xerox design reportedly would even work on your blue jeans.
I like the HP chip they made that outputs quadrature on 4 pins - and I made it instantly hard-wired compatible with Amiga and Atari 9 pin mouse ports. I made 40 PCBs and hand made a dozen of them into other mouse plastic cases. One way to solve the focus difference with different "ride-heights" is to use a Green or Blue LED.
If you ever have an offshoot channel, can’t go wrong with the name “HP Confidential “ . Or it could be the title for the next installment of “Halt and Catch Fire”.
My first optical mouse was the: "Microsoft IntelliMouse Explorer", top side silver, bottom with a red LED light. Everyone in my family did got one of these mouse. This was a massive improvement to the balls, I had to clean this balls and the little roller inside very often.
My favorite mouse is Apple’s Mighty Mouse. But it has several issues, chief among them is that the little trackball has a mechanical linkage to the inductive sensors that measure its rotation, and that linkage is prone to being jammed up by debris. Do you think it would be possible to optically measure the 2-axis rotation of a small (5 mm) rubber ball?
No problem. Those balls are always dirty enough for the sensor to have something to track on them. How long would the sensor stay clean is another story.
This type of hoarding behavior seems to be a common trait among EE enthusiasts-“I might *need* this $2 component one day!” Were the pins on those packages offset (for tessellation during production), it looked like they were staggered on each side?
@@djmips The real test of an engineer’s conviction comes down to how abstract and/or esoteric their compulsion to collect becomes-a bucket of random passives is “high functioning”, logical even-but harvesting the quartz glass coverings off of space heater elements and purchasing obsolete/damaged RV Dish Network satellite boxes off eBay-that’s when one realizes they really ought to get out more often. We’re probably on some sort of psychiatric “spectrum”, but it’s unclear as to what disorder it describes. “Binge Tinkering Syndrome”? “Moog’s Disease”? “Attention Surplus Disorder”?
I've always wondered if an optical mouse would work if it was sitting on a good mirror, but not enough to actually try it. My mind works harder than my body. :)
Are you the only one in your group of friends with a RUclips channel? I think it’s pretty nice of them to give you the stuff they were going to throw away. you have some nice friends
You should give away some of the stuff you've gathered as a pack rat over the years as prizes on your channel. I'm sure there's a number of people who watch your channel that could find use for those items.
I still have my Microsoft Mouse. It is great because there is no ball to get tangled up in cat hair. Just clean the lense with a q-tip about every year.
What was the price of the first Microsoft mouse? Recently I bought a (junk) optical rechargeable chinese 2.4GHz wireless mouse for $1.99 including shipping😂
Not pack rat - preservationist 😂 Thank you for sharing a bit of history with us. Regards, David

I work for Motorola back in the 70's and that was my job die mounting on the IC packaging circuit, great experience back then
The odd/even 0.05" pin spacing is unique, but it reduces the positioning ambiguity from 0.1" spacing

They called it "deskmouse" to differentiate from the "basement mouse"

@@IMSAIGuy That’s interesting, I’ve never encountered staggered pin DIPs. Thanks.
By staggering leads, you get more more devices per leadframe. cost saving step
“I might need this $2 component one day!” - but every once in a while "I knew I would need this!" and then it just reinforces the hoarding. ;-)

not this design, there are others the use a type of interferometer that I have been told still works on a smooth surface

Approximately when was that first optical mouse chip developed?
the optical Microsoft mouse was released in 1996
You didn't need to meaure the wafer. 4" and 6" (and very rare 5") wafers have flats. 8 in wafers have notch. And they break very easily!
The daddy of the ADNS 2051 ? ..a 3200 FPS camera :D
Yes, kewl.
Interesting. There's a nice little video that shows how to hack that chip. See "Hack an optical mouse into a camera with Arduino and Processing".
Dedambar?
Google says that it should maybe have read de-dambar. It's the point where the single pins in the leadframe is cut into single legs (called a dam-bar)

Anything is better than cleaning louse balls, kind of small and get dirty often….
I collect vintage leds if you wanna make 100 beans for a few thousand haha
This is super cool. So happy that it was saved!
Cool.
at least they have a process flow!! mine was the crapper! U'll need some traps now! U'r infested!
That's again an amazing technology.
Thanks for the video presentation.
