A Periodic Table Table
Bike Life: Year One
Crafting an Effective Hotlink Response- bluumax cnc kit, cheap, but much assembly required. now to try to make it work with linuxcnc.

- instructables.com has all sorts of creative how-to articles.
- Working on periodic table table project. electric arc furnace requires more work.
furnace strategies:- carbon arc melting. supply enough amps and anything will melt. the problem is that it's difficult to control the temperature in the furnace, so it's only appropriate for elements with a sufficiently high vaporization point, lest our material boil away.
- resistance furnace (i.e. a toaster or pottery kiln), like this. it won't reach temperatures nearly as high as an arc furnace, but the temperature is more easily controllable.
- induction heating induction furnace : induction melting is very attractive in that it runs off of electricity, is very efficient and only heats the workpiece itself. The downside is that the material must be inductive and the electronics seem to be complicated to build and debug; I have not found a single set of reliable DIY-style plans online.
- acetylene melting tungsten carbide with acetylene : an oxy-acetylene flame burns at >3100°C which is sufficient to melt everything except tungsten. in fact, it's a nearly perfect temperature in that it fits between the melting and boiling points of many of the higher-melting-point elements (an electric arc is ~6000°C, above even tungsten's boiling point). diy torch. the problem is paying for, lugging around and storing heavy tanks of flammable compressed gas.
- solar furnace, demonstrated by a fresnel lense furnace. although to melt the stuff i want, even a 65 inch fresnel lense capable of generating 3000°F+ isn't enough (though it would be neat to try and smelt iron with it...). parts for a homemade solar furnace such as the solar death ray, but would require more space and would be a lot of work to align properly. also, it only works on sunny days(!)
- The Toaster Project is an attempt by a British student to create a toaster from scratch, starting with mining and smelting iron ore. he uses a microwave; interesting idea. i like this project. microwave melting smelting in a microwave

: bah, need real table saw. drill press would be nice too. - Medical marijuana tax and retail laws
Once medical marijuana begins generating revenue for the state it will be impossible to go back. No one will want to pay for it. A terrific side-effect of the current economic slowdown that has everyone running around like chickens with their heads cut off.
To maintain some semblance of consistency in U.S. policy it would make sense to downgrade cannabis' status from Schedule 1. It would be shocking to see a reformed American drug policy based on science and reason rather than conservative ideology, but don't get your hopes up.
