these kids don't know anything about this.

if you were talking about ordering RAM from newegg, then they'd have something to say

11/26/2005 11:24:04 PM

haha losers

11/27/2005 12:01:20 AM

Excoriator half the damn tech talk is ECE.

You're the dip shit that couldnt even be a salesman at Best Circuit Buy City.



Hey dumbass, get your company to make me some PCBs .

I got them all designed up.

Please

11/27/2005 5:12:06 AM

i don't care what you guys major in - all you talk about is crucial vs. kingston

11/27/2005 8:50:35 AM

GOT DAT VALURAM!!@@

11/27/2005 9:36:31 AM

CRUCIAL FOR LIFE !!!!

And yes, this che has no idea what you're talking about.

How easy is it to get into FPGAs? That is, a basic developement board, etc? I've wanted to dabble with them for awhile now but haven't taken the time to research the start up cost.

that board cost more than you can imagine to build...

if that link doesn't work goto Xilinx.com and put 210-044 into the search window and then click on the only link that comes up...

if that link works its a starter kit that has premade board
its enough to mess around with it, xilinx webpack 7.1.4 tools are free... but they suck... and they aren't very intuitive... FPGA's are a whole different world, expecially since a LOT of what they tought me in 406 doesn't work on a real board... its bad b/c I roughly only remember things that wouldn't work...

You need to take the next class after 406 with Franzon (i'm drawing a blank on the number at the moment) and you'll see how a lot of the shit you coded in 406 won't synthesize in the real world. Of course maybe you have already figured a lot of that stuff out by now.

11/27/2005 1:27:00 PM

just need single layer PCB, no small elements at all. This isnt anything high tech, it simple stepper motor controllers.

11/27/2005 3:18:24 PM

Quinn, if it is just single layer with no small stuff, why can't you do that yourself? Or can Dumbass have it spun for you quickly and cheaply?

11/27/2005 3:23:15 PM

Yes i can iron and toner and blah blah blah

but if i can find an easy way thats cheap

ill go with it

i dont even have the components in yet, so its not a rush.

11/27/2005 3:24:35 PM

We contract our PCB's out, I wish I could get boards made at a whim... I would have hundreds of amplifier projects done by now... but I can't

My senior design board is a full corporate released board so we had to jump through all the hoops in order to get it produced. the 5day turn time on 2 boards I believe was somewhere in the neighborhood of $2k but they are 6layer boards with 2 controlled impedance layers... I think the total cost of our project is pushing $3k... here's to corperate sponsership...

I didn't have to worry about it, it was taken care of for me, but most of the other senior design hardware projects had boards made so you could talk to them tommorrow about who/where they had theirs done. I know that a typical board is only ~$100 total

11/27/2005 3:32:13 PM

i wish ncsu offered some PCB program

i agree, i have been looking at building amps for awhile now and it would make it worthwhile

maybe they do offer such a program and im a moron

here's hoping

11/27/2005 3:44:59 PM

Nah im not talking about toner and ironing, that shit sucks. Get some photosensitive boards and then you can just print out your circuits onto plain paper. Affix the circuit over the board and then expose them with any cheap flourescent. Drop them in a bath to remove the the photo sensitive coating, rinse, then drop them in some heated ammonium persulfate (which btw is vastly superior to ferric choloride) and then pull it out when you can see the etching is finished.

From the time you print your circuit out to the time you have a board ready to be drilled is probably 1 hr maybe once you have done it once or twice.

Then if you have a good drill press you can fly through all your holes pretty quickly if need be.

11/27/2005 4:02:14 PM

awsome, ill PM you for more details.

im building them for my CNC so i dont have to ever etch it out again, i can have the mill do the work >.<

11/27/2005 4:52:19 PM

actually you can get orcad student version for free from NCSU off of the ece403 website and it has PCB layout tools. its just a student version but its enough to create a basic board.

11/27/2005 7:31:26 PM

I don't know about you guys but the learnin curve for OrCad is steep to do basic stuff. The software package is designed such that very complex layouts can be done and all checked against rules. Well, the rules have to be set up first before you get this functionality and that takes an even steeper learnin curve.

Also, it's a bit of a pain to find the exact footprint of a part you need and creating one isn't that easy either.

If you think you are going to do any serious hobbyist type work as far as PCBs go, learn eagle. Even here the curve isn't exactly flat to learn (at least in regards to creating new parts) but all the "glut" associated with OrCad or Protel doesn't exist and I think you should be able to pick it up ok. I can also put you in touch with someone that can probably get you up to speed pretty quickly on it (he even used the built in macro language for part placement/etc).

Heck, I even used expressPCBs software to do a board and used some photoshop trickery to turn it into something I could use personally.

11/27/2005 8:08:00 PM

OrCad >>>>>>> Eagle

by far

but Virtuoso >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>x10 OrCad

Cadence Allegro with a librarian, a component engineer and a layout technician

although I do feel that I missed something in not having to do the physical design entirely on my own... but that kind of experience would only be helpfull in the realm of hobby stuff...

In what respect?

11/27/2005 10:18:57 PM

its just my opinion after working with them

11/28/2005 9:41:06 AM

What is the basis for your opinion?

11/28/2005 9:55:17 AM

personal preference

11/28/2005 10:05:15 AM

You know, there are some pretty good reasons this whole website hates you.

It was pretty obvious with the comparison post you were trolling. It's even more obvious now.

Eventually, Bobby will suspend you when I can get him to realize you perform some of the most subtle but nonetheless obnoxious trolling in every forum on the whole site.

Stop posting in tech talk until you have worthwhile information to add.

11/28/2005 10:38:20 AM

errrr ok.

I thought I was being pretty straightforward when I acknowledged that I was speaking only on the basis of personal preference; not sure how you're interpreting it as a troll.

If you must know, in my experience, Eagle fell flat on its face when I used it to try to lay out a highly congested PCB. And at this point I've done more work with the Virtuoso suite so I prefer it

... are you going to think this is a troll?

weirdo

11/28/2005 10:51:26 AM

Yes that reply was a troll too.

Or maybe you really are just that stupid. I mean it fits, you haven't given one smidgen of worthy advice in your entire Tech Talk history.

11/28/2005 11:07:23 AM

ok, like i said - i was just speaking on personal opinion - not trying to give advice.

11/28/2005 11:09:38 AM
