EEVblog #105 – Electronics Thermal Heatsink Design Tutorial

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.

EEVblog #86 – Buy a real Analog Oscilloscope PLEASE!

Dave is sick of getting emails asking if the cheap toy DSO’s and FPGA/PIC/AVR oscilloscope kits are worth buying.
Guess his response… answers by telepathy please.

EEVblog #75 – Digital Multimeter Buying Guide

Who else in the industry can give you 52 solid minutes of beginner advice on buying a multimeter?
Dave of course!, who started out wanting to give some “quick” advice, but as usual Dave likes to rant…
So you get a feature-by-feature breakdown on what makes a good multimeter. It turns out there is a surprising amount of stuff to talk about on the humble multimeter.

And this is what happens to cheap meters when you overload them:

EEVblog #72 – Let’s Design a Product

In this supersized lecture length episode, Dave foolishly attempts to explain how to design an example product (the uCurrent) from start to finish.

EEVblog #67 – Hacking the Princeton Tec EOS LED Headlamp with a Cree XPG

Dave does a teardown of the Princeton Tec EOS headlamp and mods it with a new Cree XPG LED.
Throw in a quick reverse engineer of the circuit, gratuitous scope shots, torturing a thermistor, a practical demonstration of why you really do need 5 multimeters on your bench, and as usual Dave finds no problems filling up 25 minutes.
