EEVblog #140 – Battery Capacity Tutorial
Posted on January 23rd, 2011 23 commentsEver 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. -

EEVblog #110 – Let’s Design a DC to DC Switchmode Converter
Posted on September 10th, 2010 49 commentsDave takes you step-by-step through designing a DC-DC converter using the venerable MC34063. And then he build it and checks the performance.
An online calculator is here:

EEVblog #105 – Electronics Thermal Heatsink Design Tutorial
Posted on August 15th, 2010 20 commentsA 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.

EEVblog #95 – Linear Regulators, Closed Loops, Simulations, & Brand Shenanigans
Posted on June 20th, 2010 29 commentsA bit of a follow-on from the linear regular episode. Dave dances with a simple linear closed loop circuit he built, and bodges it up in LTspice to get a remarkably consistent result.
Not really a tutorial, just a few random tidbits.
