High Voltage Fun!

Tesla coil plasma

All sorts of nifty cool high voltage projects.

This section deals with the power supplies which output mich higher voltagethat is safe to touch (voltages above 75V DC). NOTE: High voltage power supplies are very dangerous circuits which should only be built by persons who know exactly what they are doing and do it safely. High voltage power supply can easily kill you if you do mistakes with it.

Heavy Lift Blimp

IThese would be so cool to see floating into a military opperation. I wonder if they can take a direct hit with an anti tank weapon.

The Walrus operational vehicle (OV) is intended to carry a payload of 500-1,000 tons (that’s 1-2 million pounds) up to 12,000 nautical miles, in less than seven days and at a competitive cost. Given these enormous capacities, they would mostly be used to deploy full-scale fighting units (for example, the components of an Future Combat Systems Army Unit of Action) quickly, getting them to their site with a minimum of equipment reassembly work required. The ideal is that transported forces should fully ready to fight within six hours.

Watch Out For That Rake!

I guess there is a day for just about everything isn’t there? Well September 10th is the day when you might want to keep clear of your neighbors garden. Or not, depends on the neighbor.

Get ready for the inaugural World Naked Gardening Day (WNGD)! People across the globe are encouraged, on September 10, 2005, to tend their portion of the world’s garden clothed as nature intended.

Gardening has a timeless quality, and anyone can do it: young and old, singles or groups, the fit and infirm, urban and rural. An elderly lady in a Manhattan apartment can plant new annuals in her window box. Families can rake leaves in their back yard. Freehikers can pull invasive weeds along their favorite stretch of trail. More daring groups can make rapid clothes-free sorties into public parks to do community-friendly stealth cleanups.

Stealth cleanups? I’m heading to the local university in hopes of spotting some of these.:P

Wrt54g – Unlock the Secrets!

SD card on a WRT54G

I recently bought a Linksys WRT54G wifi router and I am so darned happy to discover that it can be flashed and modded!
Here are a few of the cooler ones I’ve found:

A Wikipedia entry with links for firmware upgrades and what the different hardware revisions are. The new firmware loads are cool, lets you use RADIUS and loads of other stuff.

This one is sweet, how to add an SD card reader to a WRT54G

This project is for people who would like to add a little storage to their Linksys WRT54G router besides the builtin 4MB flash ram. What we will do is connect an SD card reader to some of the GPIO pins of the CPU found inside the Linksys and with the help of a little driver we can use as a block device from Linux. This means that if you compile your kernel for the Linksys with e.g. support for MSDOS partitions and VFAT you will be able to mount, read, write, partition and so on your normal SD cards. The speed obtainable for reading and writing seems to be about 200 KB/s.

Some more information on the GPIO ports.

And if all that wasn’t enough, you can even make a robot out of it
