I can sympathize. Both are mistakes I've made too. The other bad one was rotating a board (as an entire group) in Eagle while panelizing, and so the text stays right side up but the board is upside down and so all of the text is rotated 180 degrees to what I had intended.
To try and protect myself from myself, I now very carefully look over my gerbers before I send them to China. Even so, I still make a couple mistakes on every board ...

I picked up my mail today which was on hold. Both sets of boards showed up. Actually they arrived yesterday but I picked them up today.
I ordered them on June 22 and they arrived July 9. So it took about 3 weeks.
I have noticed two thing so far. The reset button on the XMega board is on the back of the board. I don't know how I screwed that up. But it is a through hole part and it is symetrical. So it doesn't matter which side it goes on. The Mega164 board has the silk screen screwed up. I think I switched from proportioanal fonts to vector fonts and didn't recheck how it looks. So it is now goofy...
One board has several designs so I have to figure out a convenient way to cut those apart.

I got two emails on Monday saying that both of my PCB designs have been shipped. To refresh people on what I am doing, I ordered 10 boards for $50 of the...

Too bad you don't have a nice scowl saw with a fine blade. A small table top band saw with a metal blade would also be nice. ________________________________...
I have a table top band saw, but the blades are terrible. its a craftsmen and the fiberglass just kills a blade in no time. I bought the saw specifically for...
I didn't leave enough room to do a full cut with a bandsaw or table saw blade. I may end up scoring the PCB with a a box knife and snapping it. That works but...
i have a shear at work i could cut them with but it might take a week. andrew or you could take them to harbor freight and "test the equipment"...hehehe To:...
I just bought a tile saw at Harbor Freight. It was on sale for $47. It has a diamond blade for wet cutting. I also bought some cut off wheels designed to cut...
I took my new saw over to Alan's last night and tried it out. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=3733 I put on the metal cutting...

there is a freeDFM website where you upload your files and it checks them for you. send you back a photo of the problem. I have an issue with eagle where the...
I had my Xmega board assembled for the robot meeting last Thursday. (Except for a crystal.) The programmer arrived by UPS 1/2 hour before the meeting so I...
I have a stamp, and find teh fact that it will only support one PWM channel at a time limiting. Alan states that the IDE for the Arduino only allows one source...
Rich What are your requirements? I had a variety of requirements for my Power Control Module. - Expandability - Serial Communication - Lots of I/O - Free...
Terry point out that you can use a bare processor chips. This is the way I woukld go if I wanted a "cheap" solution. But keep in mind it is not a "complete...
Thanks Terry! Very articulate response to my simple question. I'm thinking of a two motor line follower with a tail wheel and bumpers. I want to be able to...
Rich The AVR Dragon can act as both a programmer and a breadboard for many of the Atmel processors. It is a USB device. I've got one I received at an Atmel...
... A quick response from a lurker here. I have an AVR Dragon and I do use it. It has a number of issues that make it problematic: 1) Some people have...
I have a Dragon that has never worked. I have another one that I have never tried. Since I was discouraged by the first one. It seemed like a great idea...
Oh I guess this is the next response. But it is not the response I expected to address the cost... You will find that $30 is not all that expensive if you are...
Rich, Don't forget that the UBW that SparkFun sells is $25 and needs only a USB connection for power, programming, and communication. No programmer to buy, no...
