Electronic Designs, High Voltage, Vacuum Tubes, Teardowns, Reviews, Repairs and Travel Videos :-)
I started the channel initially as a way to show Status updates of my Prototyping Work, but after some Time I thought that eventually some of my content could be interesting for others too.

All my Videos are unscripted & unedited, what means that there will be some misspelling and eventually some brain-farts :-)
