Dave show you how to solder a small 3 axis accelerometer LGA surface mount chip “dead bug” style onto a microcontroller prototyping board.
This technique allows you to easily prototype projects using tiny SMD components designed only for reflow soldering.

Sorry, no chat window overlay, it got corrupted.
Mostly almost 2 hours of Q&A, so a good one to listen to instead of watching. Just start watching when you hear something interesting happen!, like when Dave opens up his 1980′s vintage LED clock project.

A follow on from some of the recent blogs that have involved basic thermal heatsink calculation. This time around Dave takes you though the basic theory of thermal design and how heatsink calculations work. Then there are some real world temperature measurements to see how close to the theory we get.

How do you read a heatsink thermal response graph? What is emissivity? It’s all here in thermal design 101.

Is it one of those brilliant “why didn’t anyone think of that before” moments, or just another silly patent on a really obvious idea?
Is it workable in practice?
Can YOU bust the patent by finding prior art before 2006?
