I've been quiet for too long... and I need to publish some more tuts on the NetDuino and other things I have been up to, but in the mean while check this out:
I picked up this fully functional valve based scope for R200 ( < $30 ). It was dirty as all hell, but I spent the last few evenings cleaning it up and now its shiny :) What a piece of old skool awesome! I think this is over 40 years old...
Don't make 'em like they used to!
