Looks like a converted garage?

Do you still use that D-sized plotter? :-)

That cat looks awfully dead in the 2nd photo, lying on top of the computer.
:-) Hmm... and a second one on the car... how many of those critters do you
have!?

I like your drill press-cum-mill...

Bingo!

We downsized about a year ago, and since I'm not doing much hardware
production any more, it's perfect for development.

ANSI A to E size, actually, but generally no.

Three; Monty, Missy, and Josie.

Monty was the dead-pretend guy on the Windows box, Missy was asleep on
the chair, and Josie refuses to pose...

Thanks. :-)

I worry a little about side-loading the bearings in the quill but, so
far so good.

What's in that photo below your company name?

WW Grainger.

On the clock it says: "Dayton model 5H571", but a search at Grainger's
shows an entirely different face.

Bits of wire trimmed off components that seem to get everywhere.

Don't get many "offcuts" from SMT. ;-)

I often work in just my socks, but regular clothes :-) I meticulously
save any clips of consequential length (and the Teflon wire scraps),
to use as jumpers on my bread-boarding system:

Being a Spice guy, I wouldn't have thought you did much bread boarding.

If anyone knows a good source for those double sided perf boards (power
planes top/bottom and isolated holes, like Jim's pic, over the entire
board), anti up. Those seem to be hard to find at a good price. perfect
for wirewraping.

Here's the Vectors series, I think. As usual, Digikey thinks they are
made of gold

Being a Spice guy, I wouldn't have thought you did much bread boarding.

Not for chip designs... for my "G-jobs"... I tinker a lot with
home-brew gadgets, like aircraft noise trackers, school bus
annunciators, light controls via the street light sensor, etc ;-)

I laid that out myself while I was at GenRad, to ease bread-boarding
of analog I/C's from so-called "kit parts". I may still have the
original films around here somewhere (I save everything :-)

I'm just about out of scraps from that system (after 33 years :-)...
they were one-foot-square to start!

So I'm considering making a six-socket version for my G-job needs...
maybe run it thru one of those cheapy PCB houses (it's only
2-layers/sided)... maybe add some surface mount type pads.

For fairly high-speed (~100MHz) prototypes which need double-sided
copper, I like to use Vector's 169P44C2 cut down as needed, their T44
terminals to carry parts on one side and wiring on the other, and a 1/8"
drill to _judiciously_ remove the copper from around the holes where the
terminals need to be pressed in and connect to neither the power nor the
ground plane.

I've used their pad-cutting tool and found it to be absolutely worthless
after a couple of cuts, so I now use a vanilla 1/8" drill bit, in a
drill press, with the depth of cut set to just barely remove a 1/8"
diameter disk of copper around the isolated hole.

I've got some photos, somewhere, which illustrate the concept and, if
you're interested, I'll go find them and post them.
