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.

Dave takes you through everything you need to know to do good quality soldering.
Part 1 is all about the tools you might need.
A lot of this was already covered in my general lab tools video.

One of the more obscure controls on an oscilloscope is the Trigger Holdoff control. A dedicated control on most high end analog oscilloscopes, and a main menu option in modern digital scopes, yet often poorly understood. What does it do and how does it work?

Who else but Dave can turn what was supposed to be a simple 2 minute AVR ISP hack video into a 30 minute episode on designing and measuring the performance of an LM317 voltage regulator circuit, with a bonus shootout between the Fluke 87V and the Gossen Metrahit XTRA multimeters?

Ever wanted to know what battery capacity is? Dave takes you through everything you need to know about amp-hours, mAh, watt hours, internal or series resistance, temperature effects, battery cutoff voltages, and characteristic curves.
Part 2 coming soon.
