Re: Dummy layers to get 4-layer rules in DRC?

The board is $8 instead of $2.5 and I don't really mind as the alternative is my other supplier at $200. My other supplier would give me 5 panels of 90 boards pr panel in 5 days though. I just don't need $200 worth of junk if they don't work... Also, I actually may need to go 4-layer so then the la...

Re: my first,simple PCB design in eagle-did I do it right?

Not bad for a first attempt at hand routing. (12 mil trace can handle half an amp so you are probably ok) 12 mil can handle more than that. depending on temperature rise allowance, it can handle ~1A. I've got 16mil traces, can handle 1.2A Also, you should google what a decoupling capacitor is for, ...

Re: possible to have two power polys on the same layer?

I guess you're right, I just figured that it would fill the best of both out, but what you said makes sense. I tried it on a small area and it worked as intended, so I'll just have to hand draw the entire 5v plane out. Edit: I guess what I am looking for is if there is a way to have a wire expand ou...

^^ Agree. I've made dozens of parts myself. just grab the data sheet and start copying. Very easy to do.

In eagle, specifically 6.1, is there a way to have two power polys (+5 and GND) on the same layer, but of course isolated? I've got 5V and GND traces all over the place, and I'd like to be able to lay down planes for 5V where possible to increase current capabilities. I have a problem though, becaus...

dorkbotpdx and advanced assembly I am working with so far there awsome! Dorkbotpdx has fast boards and made in USA. How much are you paying for assembly? I'm workign on a 39.3x54mm board, that has 40-some parts on it, 1/3 are 0402 or QFN packages...very hard to hand solder. I have been using stenci...

I've been in a customer or technical support position my entire life, so I think I might know one or two things about providing decent customer service. Up until now, Sparkfun seems to have decent customer support, but I cannot make that claim anymore. I placed an order at the end of July for qty 5 ...

you can start with something like this: int incomingByte = 0; void setup() { Serial.begin(9600); } void loop() { if (Serial.available()) { incomingByte = Serial.read(); } Serial.println(incomingByte,BYTE); } however this will only read one byte. What you need is something more like this: int incomin...

dude, u have the same reader?... Cr003t? I'll try this out.. I am going to get confirmed 125khz rfid tags tday.. Had unconfirmed tags maybe 13.somethint mhz.

I got this rfid reader today and it dosnt seem to work.. as i understand, if i connect it's tx to arduinos rx, it should give me an STX value of 02h. Or something like that.. So.. How is this supposed to work exactly.. My code is: int incomingByte = 0; void setup() { Serial.begin(9600); } void loop...

Re: Can you do castellated pads with BatchPCB

Is it possible to do castellated pads, which appear like a normal circular pad cut in half, with BatchPCB? These are boards that you place flat onto another board, and solder in the cup. http://screamingcircuits.typepad.com/.a/6a00d8341c008a53ef010535d51230970c-800wi Thanks! -Seth you should try co...

I've looked for a long time, and BatchPCB seems to be the cheapest so far. You could try one of the chinese suppliers, like PCBCART.com, but they have high setup fees for the first run of each design. My recommendation, consolidate your order, so you run 4 or more designs at once...you'll save on th...
