Re: beginner seeking for necessary utilities
Hello, Etch resist pens are just those permanent laundry
marking pens. So I only need to seek for a permanent marking pen? Do you know the exact material which is used in these sort of pens? (so I could check whether it is found in the pen' description) You can also get sheets of rub-on shapes of PCB traces
and IC pin patterns. They work just fine directly on
the copper as etch resist. Yeah, I know these sort of sheets, but I rather design my own PCB, print and etch it to the board (the rub-on shapes don't fit complex designs, at least that's what I think...) I'm in the USA and there is Radio Shack in almost
every town. You can also order from companies such as
Digikey and Mouser
RadioShack just openned two new stores in Israel. I'm going there today in order to see if they are selling the "Complete PCB making kit" that was once sold in their website. Thanks for the links, I will pay a visit to those websites. Look through some of the past messages for opinions on
different kinds of etchant. Ferric Chloride has its
own set of problems. I don't like it because it is
just way too slow. What would you offer me to use? A link to a website that sells it would be nice ;) Best Regards, Aviv Revach

check out www.lavenir.com for a free Gerber viewer.
they also have a 516 page pdf file which has all the d-code
conversions etc

Re: Sumo Robot list invitation [Yahoo! Clubs: Wires and Circuts]
I've started a group called SumoRobot. Sumo Robots or
SumoBots are small robots that try and push each other
out of a small flat ring area. They are -not- supposed
to damage each other. There are numerous weight
classes from Ant-weight of several hundred grams to
Japanese Sumo class at 3 to 5Kg.
I intend to advertize to get people to the list. Other
robotics lists are more general than I am looking for.
I'm interested personally in the autonomous 500g Sumo
Robots but discussion of other Sumo Robot classes is
welcome and invited.
I've already posted a small number of links in the
Bookmarks section there. I'm interested in more links,
especially to suppliers of motors, gearing, wheels,
and pre-geared motors.

Re: beginner seeking for necessary utilities
Not sure where to direct you for the ferric chloride, but I have used the
Sharpie brand marker pens made by Sanford for etch resistant pens and they
worked great. Available in a variety of widths and available at the local
office supply store.

Re: Hints and Kinks - Fast PCB's
I've been using positive photo sensitized board. If you use a PCB layout and print transparencies in positive it is possible to get 8 mil lines every day.

I use Ultiboard, so have the option of generating output in HP
Graphics Language or Gerber. Looking at the file of the same project
produced in the two languages, it seems to me that it would be
fastest to use a translation of Gerber to HP G/L -- convert
the "tools" that Gerber flashes for different pad sizes and trace
widths to different pen sizes.
With HP G/L and Ultiboard, a circle is drawn with the "Arc Absolute"
command, using a chord angle of 1 degree. This is very slow. I
use "Search and Replace" to change the chord angle to 15 or 30
degrees which speeds it up dramatically. I guess you could
use "Search and Replace" to draw a circle using CI, but this assumes
that the current pen position is the center of the circle (which it
is not) and you need to recalculate the coordinates with a little
trig to determine the true center of a circle.

Re: What to do if you have a virus
At 07:56 11/01/2002 -0800, you wrote: First off, let's take this off list. Before you take it off list... In addition to real live viruses, there are also a number of hoaxes doing the rounds - email messages, again that you will receive from people you know, with messages of the form "Go look on your hard disk for file named XXX.YYY & if you find it, delete it & flush it out of your trash can. Then send this message to everyone you know". The result, if you take it seriously, is that you delete a perfectly good Windows utility file or whatever, and tell your mates to do the same. If you get messages like this, you can look up the encyclopedias held by people like Symantec (who sell Norton Antivirus), Macafee, etc. and check whether the warning is real or not before you a) damage your own system or b) make a complete a$$ of yourself by sending the hoax on to your mates/colleauges/clients etc. I have had about 6 of these forwarded to me in the last year by people who didn't know any better!

What to do if you have a virus
First off, let's take this off list. 2nd, get a virus checker. You should be running one. My wife wasn't, her computer got infected without even getting it by email, we think it was from someone's website. 3 days after she started running without a virus checker, Norton Antivirus reported more than 2000 infected files, none could be cleaned but only quarantined. I ended up doing an FDisk, Format, and Reinstall. 3rd, -don't- -open- -executable- -attachments-! Not without scanning with a current virus checker first, and even then if you weren't expecting it, don't open it. So many people tell me, "But I only open them if they are from someone I know!" Well, duh, that is how the virus propogates. It uses your list of email addresses so you are SENDING IT TO PEOPLE YOU KNOW!! 4th, change your default settings in Windblows- set it so you can see the three letter extension for -all- filetypes. IE, turn off "hide extension for registered file types". Note the name of the virus below- If Windblows hides the ".scr" (script), then it looks like an MP3. About the only things that can't hide viruses these days are JPG, GIF, PNG, RTF, and TXT files. Please, last word on the list on viruses. Try the newsgroup alt.comp.anti-virus and you'll get a lot more experienced people. I use Norton AntiVirus from Symantec. You can download a 30 day trial version.

HP7550a plotter and Windows 2K
Does anyone have any experience connecting an HP7550A plotter to Windows
2000?
I am having some problems with cables and drivers.
I plan on using this plotter to directly plot onto a PCB for etching if I
can get it to work.
Thanks
