About

We are just friends dabbling with electronics, software and …. stuff, and need a place to document the knowledge we obtain.
So we decided that if we share our questionable knowledge on this blog, others might find it useful or simply blow themselves up because we got it totally wrong đŸ™‚

Most information on this blog is probably stolen from somewhere else (sorry), misunderstood or simply plain wrong – so if you use it, it is your own risk and expense.

BEWARE – YOU HAVE BEEN WARNED!!! đŸ™‚

Enjoy!
