  • Nice vid! I’ll suggest a new title: Everything you need to know to know about Wi-Fi.

    It isn’t so much about how WiFi works, but really just listing the most important technologies and standards that allow it to work.

    I especially liked the parts about the various transmission techniques, but I’d also suggest that you notate (in a youtube-comment-thing?) which layers of the OSI are responsible for implementing each of these standards of the wifi-alphabet-soup.

  • Check out the Howler Arcade Controller. It’s open-source and programmable. It can handle all those buttons and more and LEDs. http://www.wolfwareeng.com/

  • For all who want a drop-in I2C replacement, Check out the DS3231 breakout from lovelectronics. Just got mine for a clock project that I’m working on. The new SparkFun DS3234 is good and all, but it is SPI.

  • I ended up doing that with 16 pieces of 3-pin, but it’s super-ugly.

  • The tube contains a mixture of Neon and Helium gases at low pressure. My guess is that air is getting into your tube and blocking the radiation or throwing your counts off. Sparkfun sells replacement tubes now. https://www.sparkfun.com/products/8875

  • The schematic shows that the red charging LED is connected directly to vSource, so it will come on as soon as you apply power.

  • For everyone who was looking for more information (and usage instructions) for this product, here’s a link to the designer’s website: http://www.pololu.com/catalog/product/750

  • For everyone who wants more information about this product, I found the designer’s website here: http://www.pololu.com/catalog/product/751

  • It is, indeed connected to pin D2. (the third digital pin if you count from zero)

  • I second this (or something like it). I’d like to use something like the Pushbutton Power Switch together with this shield to turn off my project’s power usage…. https://www.sparkfun.com/products/8904

No public wish lists :(
