Re: Eagle: Polygons have fallen apart

When I draw the polygon after routing the first time, it's just an outline. Once I run it through the second autoroute, it creates the polygon pieces, and connects them to the ground traces. Is there some other operation (aside from autoroute) that causes a freshly drawn polygon outline to be realiz...

Re: Eagle: Polygons have fallen apart

Nice. That worked.

I wonder if it would be possible to create a ULP that says:
1) Delete the ground polygon if it exists
2) Autoroute the board
3) Create a ground polygon to the dimension of the board
4) Autoroute the board again.

Eagle: Polygons have fallen apart

First of all, I understand that real engineers manually route. I'm not trying to start a debate between using the autorouter and manually routing. What I am trying to do is to figure out if there is a way around this 'polygons have fallen apart' issue. I design two layer boards. I usually try to put...

Tabs between depanelized boards

Is it typical for boards to include the little tabs between them? I just got back three boards from OSH Park and all three had tabs similar to these: tabs.jpg The other board houses I've dealt with (primarily batchpcb, but also another company based in Canada whose name I forget) never had these lit...

Is there a list of standard mm drills somewhere? I'm also curious whether they round up or down (my guess would be up).

What size hole to drill?

I have some pins that I've measured to be about 1.8mm / 0.71". What size drill should I use? I'd like a fairly snug fit. In particular, are the drill sizes are before through-hole plating or after through-hole plating. Also, is there a list of the standard drills that are available at batchpcb, and ...

LED visibility in sunlight

I have a project I'm working on that displays a bar graph using about 10 SMD LEDs. They are super-bright LEDs, like these: http://www.ebay.com/itm/50pcs-Red-1206-Super-Bright-DASH-SMD-SMT-LED-Lamp-Light-/120750035209 I'm using 220 ohm resistors on a 3.3V microcontroller (I've been playing with resis...

Re: Has BatchPCB shutdown?

I just tried a paypal order myself and it blew up with a 'oops train wreck' message as well.

Resubmitted the order with Visa checkout and it worked fine.

MPL115A and Eagle autorouter

Hi, I'm trying to use the MPL115A from the sparkfun library. But, Eagle refuses to autoroute it, manually route it, and generally believes the footprint is in some way utterly evil. Usually I've fixed this sort of thing by adjusting the routing grid in the autorouter, but it's not working this time ...

Re: I need a LIS3LV02DQ badly

Although not as convenient as the SFE breakout board would have been, in one of my projects I used a QFN-28 to DIP-28 SMT Adapter (0.8 mm pitch, 7 x 7 mm body) (PA0066) from proto-advantage.com. In my particular case, I needed a quick and dirty way to breadboard the accelerometer.

Re: 1.27mm pitch headers

Out of curiosity, why is the header pink and the rest of the traces and pads green? Is it possible that they are one different layers, but the drcbot does not realize they are connected and thus thinks they're different signals?

Re: Multiple designs, one of each?

Thanks again guys, and if I decide to use batchPCB I shall report feedback, although, I've seen examples and the manufacture looks perfect, its sometimes the designs that are awkward ;) I've had something on the order of a dozen different designs that I've had produced and I've yet to receive an or...

Re: Multiple designs, one of each?

You can put multiple design into one giant panel, just make sure that there is 10mils of space between each design. As batchpcb charges by the square inch, what is the advantage of panelizing them yourself? Other than to save perhaps a little bit on rounding, it sounds like a bunch of extra work cu...

XBEE AES Encryption

I have two XBee Series 1 modules. They are configured with IO passing so that the value on DIO1 on the transmitter is reflected on DIO1 on the receiver. The transmitter is an XBee Pro and the receiver is a regular (non-Pro) series 1. On the receiver, I set EE=1 and loaded a 16-byte key into KY. To m...
