  • Uh … The letter is dated March 10, not the 7th, and it refers to 250 digital multimeters, not 2000. Perhaps the business model of buying cheap stuff from the Alibaba web site and selling it on your own site is coming to an end?

  • Tubing by it’s very definition is hollow; otherwise it’s call “rod”. It’s a bit like saying an angular annulus.

  • Damn it man! What’s the answer? He can’t keep stomping the question forever!

  • No adult large tee shirt?

  • It is wonderful to have someone admit that luck, or more accurately, being in the right place at the right - opportunity - was an important element of their success. Often it is many things coming together at the right time that makes for a successful business. Without the Aduino IDE, Sparkun, Adafruit, Make, Evilmadscience, etc. would not be where they are today. Nate founded Sparkfun before Arduino, but I believe his success is deeply intertwined with the Arduino. It is great that Nate is posting this thoughts and experiences, I love reading this stuff. The Founder of Polulu has written some interesting pieces on their website; my personal favorite was his piece on open source, with his dialog with Philip from adafruit. But I digress … Good work Nate!

  • Personally I would design a 15 or 20 element 2.4GHz Yagi pattern on the plastic film. That way you could have a flexible strip antenna for extending the range of wifi project up to a mile or more. The thin-film antenna could be attached to the side of the project’s enclosure or to a window. I would use a design similar to this: http://www.ti.com/lit/an/swra350/swra350.pdf PS, Actually, I have a second suggestion now. I’ve had projects that used a LCD shield plugged into an Arduino, where I needed to access some analog pins but couldn’t because the display was up against a housing. Adding a flat, flexible conductive header between the shield and the Arduino would have been nice. You could make one for each of the four header sockets, and terminate them with the same header sockets so that the user could just solder in individual breakaway header pins as needed.

  • nice package, very professional looking. Where did you find that housing?

  • See that stepladder propped up against that door? That’s why I’m under here …

  • You are right, this will not work. What you need is an instrumentation op amp: http://en.wikipedia.org/wiki/Instrumentation_amplifier

    Unfortunately Sparkfun does not sell one.

    But a TI INA128 or 129 should do the trick.

  • yeah sure - get me some tesla coil wire and we’ll call it even …

No public wish lists :(
