Tag-only blogware
I think there’s something interesting here…Tags, not Trees. Take my new tree-structure-free gizmo out for a test drive: What is it? Whatever you want it to be: Navigation-free website. Tags-only blog. Complicated-to-simple database. Active resource picker. Knowledge and learning base. File system. Whatever. An experiment for the heck of it. Basically a different approach to organise data, finding data, and transferring knowledge. An example of no-tree-structure-at-all. Anataxonomy in practice… Link.
I’m posting this from 30,000 feet in the air using Boeing’s Connexion wireless service on their planes, so far so good. I’ll have a lot of photos, audio and video posted soon- but for now, check out all these as they upload from the air!!
I think this is the coolest clock ever..used but working DG7 tubes and a transformator cheap, one from Mullard and one from Phillips. Other CRT Cathode Ray Tube types can be used; you can even rip one from an old and maybe dead oscilloscope, then you also get the powersupply and stuff. If you are lucky the deflection amplifiers also work :-) Then your own home made Scope Clock is soon up and running, good luck. 
The shell is a festive holiday popcorn tin about 10 inches in diameter and 11 inches tall. This was lined with a layer of castable refractory insulation approximately 2″ thick. The foundry fired with charcoal with the cricuble in place and loaded with chunks of scrap aluminum. Even with the fire inside hot enough to melt aluminum (1200 to 1400 degrees F) the insulation is effective enough to keep the paint on the outside of the can intact. In fact, I can touch the outside of the foundry BRIEFLY with my bare hand without injury. 
Build your own little paper rocket – it comes complete with a pneumatic launch pad. Using pressurized air as it’s only fuel, the rocket might rise as high as five meters. No fire and no explosives are used – it’s perfectly safe for indoor use.
