"The future doesn't exist,

its ours to invent"

What is DEXTREL?

Dextrel stands for "Dego's EXTReme Electronics Laboratory" - a nickname for my spare time electronics activities. My objective is to present to electronics enthusiasts (and hobbyists alike) some tidbits of useful information. This includes sharing some of the simple but serious non-commercial DIY-projects that I have designed and built during my active hobbyist years.  I have also included some design ideas that might be useful. 

About this site

Why is it that electronics as a hobby seems slowly and surely to disappear.  One probable explanation is that most of the gadgets that you ever will need or can imagine - can nowadays be bought straight off-the-shelf. And at a cheaper price than a homemade equivalent. Why bother with the extra effort to construct yourself something - when you can buy it ready-made? When you are swapping ideas with someone you always gain something - when swapping items - you won't!! I'm glad if I can contribute to the electronics community, as it has provided me with plentiful and useful information, during all these years.


Nowadays almost everything is microprocessor controlled - and there are numerous highly integrated application-specific IC's that do most of the tricks. The ability to read an application note means that you can construct a useful circuit with less knowledge in the art and fewer parts. Unfortunately the FUN of inventing things of your own - is almost gone - almost.

Here's a list of the contents. Each header is a clickable link to the respective page.

Design Ideas

This section contains design ideas - in the same fashion as published in the EDN-magazine. The only difference is that the ideas presented here are my own. Some of these ideas were published, some should have been - lazy me. 


This is a collection of simple but usefuö electronics projects. Not necessarily complete with instructions or PCB layouts, but nevertheless, projects that have been built, and are really tested.


This page contains some personal information about myself.


A brief view back in the history of electronics - from my perspective.


My mildly schizophrenic spare-time video editing activity called Studio Kingshill.

Tips & Tricks

This is a collection of instructions about how to fix, repair or improve different gadgets.


A collection of hard to find service and repair manuals that might someday come in handy. At least I spent lots of time locating them.
