In response to my posting of the DIY hobby o-scope item, Ken_S sent a link to his “Minimalist Oscilloscope 08M Project,” which uses a PICAXE 08M chip and a Nokia cellphone screen to create a… well… minimal oscilloscope. Given that he got the phone for a buck, he was able to build the scope for $5. I like at the bottom where he brags: “Check out these impressive specifications rivaling scopes costing twice the price.”
