Yeah, it was no fun, but after 2 1/2 hours and about 2500 captcha tries I finally won. First time I've won in the 3 years that I've tried. I was starting to get depressed that I might not win. Part of the reason for using captcha was so the site didn't get so lagged down like it did in previous yea...

Captchas are kind of dull - they could have made a way to alternate between those, trivia questions, taking them to a random page - asking the user if they have purchased one before, novel kind of things like that. People -do- seem to be winning, but perhaps some ideas for next time?

Re: patented product created with SparkFun modules

I've always imagined that when using Sparkfun products - they are 'building blocks' to rapidly prototype something together. Once you have a rough working prototype, it's up to you to design a custom product using a PCB designer, a listing of the raw components, and the know-how of how it all works ...

I ran into a similar issue with the Protoshield and an Arduino Uno board - I covered the top of the USB port casing with Kapton tape to prevent electrical contact. It seems to work pretty well.

Give you the way? No. Help you figure out how to do it for yourself, yes. Have you procured this item, tested it's output - done any coding to do anything with the gibberish wonderland it gives you when you swipe magnetic cards through it?

Re: Ethernet PRO, free digital pins????

Hmmm - from the Arduino web page on the item: Arduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 ...

Re: I want to have my prototypes robot assembled

Is this possible? With enough money (or volume), anything can be done. Most places that run pick-and-place machine runs usually have a minimal run, setup fees, and batch requirements. If you are doing enough items, it makes sense - otherwise, it's gonna be very VERY costly.

Keyboards and Keypads

It would be wonderful if Sparkfun would carry usable keypads and keyboards for embedding into products. The only one you carry is a simple matrix style telephone style keypad w/o Enter key.

200VDC means the setting on the voltmeter that will read up to 200V in DC. It means you are getting -6V when running the engine in reverse, +6V in forward - and no voltage flow idle. Servos are basically motors with some insane gearing to allow them to do work with their power. The big problem I can...

I've never gotten my Arduino to work with my Mac. Ever. I had to dig out the crusty Windows laptop to develop for it. Anything that involves the use of Java, serial ports, and the Mac OS is always asking for trouble.
