I wanted a nice powerful stereo amplifier for studio use, I'm pretty sure this will drive a few pairs of headphones/speakers though I...

there isn't really much to say about this circuit as it is mostly a 8038 based function generator with a few bits added on such as a DC...

sometimes it's not always possible to get the response you want from an existing potentiometer and sometimes like me, you don't wan...

This is a very basic circuit which consists of 2 parts 1st is the noise generator which is the first transistor with no collector connecti...

This was kind of a rush thing I did today because I have a few projects awaiting various IC's which I can't publish yet but I haven...

I've been quite unwell so I have been unable to face firing up the soldering iron, I've just been lying in bed feeling sorry for mys...

first of all I have to apologize for the lack of schematic (unless of course one has appeared) I designed this on a stripboard layout (in DI...

Another circuit born from necessity, the story goes like this, the door bell I have is a wireless thing that needs it's battery changin...

A very simple Sweep Generator - it goes through the audible (and beyond) range which is useful for Impulse Response recording and other stuf...

after building my Deacy amplifier it was obviously missing a vital part - the treble booster Brian May used however instead of just buildi...
