This is the second video in our LED driver tutorial series. This video covers successful prototyping of switch mode LED drivers with a focus on using solderless breadboard Part three coming up will cover designing and producing a PCB for...

Hi, Another quick post before whilst we get our ChipKit tutorial finished today; we have been designing a circuit which is powered from a thermal battery. These have a fairly slow voltage ramp rate when they are first powered on,...

This is the third video in our filter design series and we’re finally looking at variable filters! We’re starting off with an overview of some basic techniques and then switched resistor techniques in detail, building up an...

Here is a video in which we show you the build process of a new electronics bench, we also go through some of the decisions that were made. We'd love to hear any comments. Thanks for watching.

In this, our second tutorial video about filter design, we build on the topics that we covered in the last video. This time we take you through the steps to design a state variable filter of a...

This is the first in a few videos looking at analogue signal filters. We’ll be building up to designing filters controlled from a microcontroller, but firstly this covers some of the tools which’ll make designing filters easier,...

Here's the first in a series of tutorials on LED lighting drivers.     We take you through the background to designing switching power LED lighting drivers and through to component selection. In the next videos, we'll take you through successful prototyping...

We’ve made it to the 4th video and in this video so moving on from our last video investigating variable frequency filters using analogue switches, we now go into more advanced variable filters using multipliers. As per...

On Workshops As the mark 4 workshop nears its fitting out period, thoughts on laying out and designing workshops are currently occupying much of my waking thoughts. This will be my fourth workshop and they've got a bit better every time....

Observant viewers may have noticed that there haven't been any videos filmed in Dave's workshop for a while. After a move a couple of years ago, the previous workshop was lost and I've been stuck without one since then. However, the new house had a back garden. And who needs a large back garden when you don't have a workshop!
