Bang & Olufsen Avant 28 television reverse engineering

Or in other words:more electronic salvaging.This television has many interesting features:two great speakers,which I will use for my stereo set,a build-in video player,a motorized foot and aluminium frame. Since this is a relatively modern TV,the early 2000's the components are fairly small,but there are still plenty of useful things to be had.

My Tube.......

These last few weeks I've been collecting old electronics again.Among my finds are a Grundig radio from the 1960's,working but with a small defect(tuning is not possible),a record player from the same era but what I got most were television sets.When I was picking up things a few years back I wasn't interested in them but finding free electronics gets harder these days.For example Video 2000 recorders I hardly see anymore.
But TV's are around a lot since a lot of people buy flatscreens or LED TV's.Of course they are big and heavy and contain a relatively small circuit board,but beggars can't be choosers......

Joule Thieves ......

So the last two weeks I haven't written this blog,even though my resolution was to write once a week.But there you have it.....In that time I have looked into new Joule Thief circuits and ways to power them.For example there is the cement battery,the Magnesium battery etc.Also I have made my first pancake coil.And the result seems to be that it works better than some coils,depending on the size and number of windings.
The coil is a Nikola Tesla patent:
