One of the most powerful tools to have when doing any type of design that involves communication protocols is a protocol analyzer. It allows you to see exactly what the communicating devices are seeing which is very useful for troubleshooting many types of problems that might come up… Wireshark is probably one of the most well-known of all protocol analyzers. [via]

If you’re looking to make your own shield for the Arduino platform, you’ll definitely need to know where all the pins and holes are located on the Arduino. After doing a quick search, I was unable to find an accurate technical drawing of the new Arduino UNO and Arduino Mega 2560. Using the PCB design files available at the Arduino hardware website, I created a detailed technical drawing of both the Uno and Mega 2560.
