I'm offering free data and advice, and you're whining about the price.

And it's not a web page, it's an FTP site.

And my camera makes jpeg's, not gif's.


Did I leave anything out?

John

My complaint was not about the price but the usability. I can use jpeg
and svg and png as well. Zips are problematic. Maybe a pdf or a tgz?

Yes, one item: It works :)

(Both the web site and the circuit)

I'm right now doing the next version, a new board, with (I hope)
improved copper-hacking technique [1]. It will include an MC10EL gate
driver, SO-8, to really wail the thing. I'd post more pics, if I
didn't think I was boring people.

[1] Score two parallel lines in the copper with an x-acto, and cut the
ends, to make, say, a long, skinny rectangle, like a 50 ohm CPW gap
for example. Tin the strip, or dab it with liquid flux. Now place a
soldering iron near one end, and lift the trace; this is the tricky
part, getting started. Once the end is free, pull it up gently with
tweezers and run the iron along the trace, peeling up behind the tip.
The heat softens the epoxy and the copper comes off like a zipper.
Very clean cutouts of, say, 30 mil width or bigger can be done.

Do they make really tiny Dremel router bits? That could be
interesting.

Yes they do. But for really fine work i prefer dentists burrs.

One of those purple ceramic Intel 486 CPU's makes a damned fine x-acto
sharpening stone.

But make sure you know what's in that ceramic material ...

Why, alumina of course! Probably some Cr2O3 and other stuff giving that
unique color (ceramic vacuum tube parts are made of the stuff, it looks
pink to dark red -- it's basically polycrystalline ruby).

You can't unzip files? I zip a lot of stuff, because a lot of my
customers have firewalls that don't let any interesting stuff in.
Sometimes I have to send files to their gmail accounts, or zip it and
rename it to .txt!

The actual issue is a hosed client the mishandles zips.

Atmel's in-bound E-mail handler blocks attachments named "*.zip", so I
send the same attachments, but named "*.piz". They go right through
;-)

One of my customers accepts .exe files if I name them .txt!

As long as they haven't used any Beryllium in it ...

The zip format is widely used in industry. How else would you beam photo
plotter files back and forth where a set easily consist of a dozen or
more individual files?

Lets see, tgz, bz, tar, and lha come to mind promptly.

Heh-heh... I have some white ceramic 4CX250R's. I hope not to drop them!

You better be 'very' careful with those. A tech at Cincinnati
Electronics nearly died when he handled a broken 4CX250 form the RF deck
of the GRC/106 he was testing. Luckily for him, the tech at the next
bench was aware of the danger and grabbed a plastic bag to cover his
hands and the broken tube. He rushed him to the rest room to rinse off
as much Beryllium Oxide dust as he could, while someone else called the
hospital. I heard the commotion, but that product was about 500 feet
away on the production floor, and I didn't learn all the details till
the next day. He had inhaled some of the dust, and had permanent
damage.

C'mon, get real. I've got a lot of clients yet the number of clients I
am aware of using Linux on they work PCs is zero. Those are exotic
formats and I bet most of my client's engineers would not even recognize
them, let alone be able to open them.

I think WinZip will open all of those formats. I know it will open
"tar", because I get files in that format from foundries in Southeast
Asia all the time.

Lots of FPGA software automatically archives a project, hundreds of
files maybe, in zip format. That's also how we send pcb designs (10-20
files, maybe) to the board fab houses.

Same here. During the hot phase of the layout my layouter and I "zip"
files back and forth, sometimes at 15 minute intervals or less.

I do the same with hex files, with Skype, to my mate with a little
assembly shop in the yUK, and he just programs the protoype live, so
to speak, I just talk him through it, if needed

Skype is good, but just cancel the call as you send the file(s) and
it's much faster, then call back. PDQ

lha is a PC format, sit is a Mac and PC format and most tools open all
of them.

Nasty! I have them safely inside my tube collection, wrapped in some foam
padding.
