Printing, just printing PCB layouts
caveteursus
I was wondering if anyone had a better way of "printing" PCB outlines
for reproduction. I use Ultiboard as my design, routing program. It allows saving the document to Adobe through Distiller. When I open the document (in Acrobat) and magnify it, however, it looks as if the doc has been saved as a somewhat rough bit-mapped file. If I just print the diagram to my laserjet, everything looks great. For now, I have been fixing up the jaggies in a drawing program. Time consuming. Anyone have a better way -- scanning in hi-res produces too big a file btw. |

ultrasonic cleaners
J Mitchell
Hi,
I have been lurking on this list for ages, as I want to learn more about electronics (especially interfacing pic chips to the real world), but as of yet I am still learning and mostly confused! :o) Although I can assemble small project PCBs and roughly understand how they work, my understanding of why "that" resistor is "there" is next to zero. I have a couple of questions for the group. 1. are there any good basic electronic foundation tutorials on the net? all the ones I find are too basic (like what a resistor is) 2. Anyone here have any experience of ultrasonic cleaning baths? I have the schematic for the electrical side, with an explanation of many of the components, but I have no idea what specific components to use, anyone interested in looking at the schematic, helping me make one of these and furthering my electrical experience and understanding? thanks in advance Jon PS: Anyone here ever known someone to buy one of the cheap (under $300) fibrescopes? (also known as a borescope or endoscope)... I would love one of these, but I suspect they are trash. |
Re: ultrasonic cleaners
Jon:
Here are some various electronic links. Perhaps one or more will be of interest/use to you. I realize Radio Shack is a Yank firm, but I have seen them there in smaller towns outside London, so perhaps there is one near you. The ones here, at least, carry "basic" books, and if you can find one with a helpful/friendly staffer, you might become a PhD in a week! Regards, and good luck!

Sean I actually purchased my tank at Circuit Specialists. Here is the spec sheet on it. As you can see it uses a standard fish tank heater and pump. The air is pumped into the side at the top and it travels down the side to small holes in the bottom its that simple. You just want gentle agitation of the ferric chloride. Pick up the FeCl at any radio shack. The heater need to be set till the tank is warm to the touch. It takes only about 3-5 mins to etch the board. Use gloves and other safety equipment. Hope this helps Derek -----Original Message-----

Re: EasyTrax DOS drivers for HP LaserJet 1100
Wolfgang Maier
As far as I can recall, EasyTrax came with DOS drivers for a HP Laserjet Printer, Epson compatible Printers, and several pen plotters. I'm pretty certain I still have my disks, so if you get stuck, I can probably get you a copy of the drivers.

As the original driver was for a Laserjet 1, I think this should still be suitable as new Laserjets just use a superset of the original PCL driver language. Regards, Wolf Maier At 10:18 PM 18-02-02 -0600, you wrote:

Re: Ads banned or allowed?
Hans
Thank goodness someone figured out what I really intended... yes it is a
warning. I am not the only person that feels like this about Easy-PC. I really don't care if I sell it or not ! I truly tried giving these people every opportunity to fix the well documented bugs and even spent another $75 on the Version 5 upgrade, only to find to a large extend the bugs are still there. According to another eGroup a Company called West Dev purchased NumberOne (Easy-PC) and are now selling a different program, it is called Pulsonix...... the Schematic drawing portion of the program is free, but the PCB layout portion costs several 1000 dollars... ! If you know Easy-PC and download the Pulsonix you will notice they are very similar. The point I'm trying to make is exactly as Harry saw it... its a warning. OK, I know I should not have purchased it. But 20/20 hind sight works well for most people. I gave them 15 months to fix the problems and have documented each and every email, and phone call to these people, they simply do not make the effort to fix bugs. They chose not to do so, and that's why they ended up on my other web site COS (Change Of Subject) As it happens this crusade of mine has a positive side, I found HomeBrew_PCB .... I have been making my own PCB's for the last 35 years, from the early days of painting copper clad boards by hand, to today when I make 8 mil traces as an everyday affair. Examples of my home made PCB's are scattered all over my web site. I silver plate my boards, I expect you all know how to do that. So I look forward to asking a few questions, mostly about how to do through hole plating at home, other than conductive ink and electro copper plating in sulfuric acid baths, does anyone have a good simpler solution.. If I offended anyone, I'm sorry, and I apologize. Best Regards Hans W "Harry W. Lewis" wrote: I didn't take that message as an ad but as a warning. SomeoneADVERTISEMENT

Re: Ads banned or allowed?
I didn't take that message as an ad but as a warning. Someone seriously trying to sell something usually doesn't start out with calling the product "trash".
CAD programs are expensive in both money and in time to learn and really evaluate them. An early heads up can save a lot of both. Commercials of the type "My product is wonderful - buy it from me now" probably should be banned. As I said earlier, I didn't take that particular email as a commercial.
