An Introduction


Hello there, my name is Silas Ernst. I'm an engineering student and I enjoy restoring and working with antique radios and laboratory instrumentation. I've been fooling around with "hollow state" devices since I was in 6th grade, and this website is devoted to some of my projects.


My Bench


I suppose the About page is as good a place as any for a picture of my workbench, since it's almost like an appendage... This thing is constantly changing as I find cool gear to restore and add to it. Here's a recent picture with a list of the equipment.
