Jim writes in with a cool upcoming class @ TechShop...
Most makers love to watch combat robots fight to the death on shows like RoboGames, BattleBots, and Robot Wars.The folks at TechShop in Menlo Park, California, are conducting a special 2-day intensive class called "Build A 60-Pound Combat Robot". The class gives you the opportunity to build your very own fire-spewing, buzz-saw wielding combat robot with the personal help and guidance of veteran combat robot builders.
The expert instructors for this class include Matt and Wendy Maxham (Team Plumb Crazy, with robots Sewer Snake, Pipe Wench, and Devil's Plunger), Stephen Felk (builder of robots Voltronic, Pump, Plasma), Kevin Barker (builder of robots K2, Terminal Velocity), Gary Gin builder of (robots Original Sin, The Big B), and David Calkins and Simone Davalos (they run RoboGames, the world's biggest robot event).
The class happens Saturday September 13 and Sunday, and September 14, 2008. Up to two people can attend for each registration and work on a robot together. Registration is open now at the TechShop web site.
This is a great demo of block printing in India. (not my voice on the video) It's amazing how accurately the printer can line up the successive prints by hand. The blocks themselves are gorgeous as objects; I have some that I've used in mold-making for casting glass.

Our first MAKE host for weekend projects Bre Pettis, has a new show coming out this month on the History Channel called "History Hacker" - congrats Bre, looking forward to watching!

We had a commenter that was really upset about the Large Hadron Collider (or as I like to call it, the biggest refrigerator ever made). I also received a few emails, with the same concerns. Here's what the commenter said and below that, the latest from Science Daily...
This experiment is sick and those that think it a joke are sick. The scientists are terrorists in threatening mass destruction. They have no right to veto my existence, the lives of my children, life on earth in all its wonderous beauty and complexity. They have no right to threaten the people of Earth with mega death. The experiment has to be stopped at all costs. No data or knowledge is worth this kind of risk. Science has reached its limitation. People were quite happy in the past with simple pleasures. No one needs this science or data. we have too much already. Humans need to return to simple and sustainable living and not be threatened by a minority of freaks with over sized brains and no appreciation of Nature and everyday things like mountains, birds, insects, flowers or the sunrise.
And here's a snippet from Science Daily & The Review of the Safety of LHC Collisions. Journal of Physics G: Nuclear and Particle Physics, September 5, 2008.
A new report provides the most comprehensive evidence available to confirm that the Large Hadron Collider (LHC)?s switch-on, due on Wednesday next week, poses no threat to mankind. Nature?s own cosmic rays regularly produce more powerful particle collisions than those planned within the LHC, which will enable nature?s laws to be studied in controlled experiments.The LHC Safety Assessment Group have reviewed and updated a study first completed in 2003, which dispels fears of universe-gobbling black holes and of other possibly dangerous new forms of matter, and confirms that the switch-on will be completely safe.
The report explains that if particle collisions at the LHC had the power to destroy the Earth, we would never have been given the chance to exist, because regular interactions with more energetic cosmic rays would already have destroyed the Earth or other astronomical bodies.
The Safety Assessment Group writes, ?Nature has already conducted the equivalent of about a hundred thousand LHC experimental programmes on Earth ? and the planet still exists.?
I think the problem is that when you ask a scientist "is there *any* chance things could go wrong" - they will always say well, sure a 0.000000000x chance... it's not zero, but it's also not exactly like pulling the slot machine handle when this machine is fired up either. I do agree with the commenter though, "they have no right to threaten the people of Earth with mega death".

I think this works better as a DIY project than an actual marketable product: glue an enter key on your doorbell for dork-tastic hospitality. Via Geekologie.

I found this amazing marble machine on YouTube - the details are fantastic! The video is a little fuzzy, but there are some good close-ups of the workings.

Hot glue guns & LEDs - two great tastes tools that go great together -
What would I do without LEDs and hot glue? They are integral components to nine tenths of my projects. Well, while I was working on my first instructable I noticed that the LEDs I'd hot glued onto the wires kind of made the translucent glue glow a bit. I thought to myself, "What would happen if I put the glue on the focus end?" And so, this instructable was born.Good idea - it's always awesome to discover new uses for common items. Find a a good deal on bulk glue-sticks and you've got an illuminated art installation. - Hot Glue LED Diffusion

Here's a good project for those interested in getting started with microcontroller circuit builds - Izuna posted details on building a PSX controller --> USB converter using an ATmega8 chip -
Sure, you can buy an extensor and cut the cable, but you can also buy a PSX to USB adapter for cheap if you want. This is not the point, the point here is make something yourself (and if you have the rights tools beforehand, this is cheaper than buying the adapter [At least I think it is in Brazil]).
[?]
The circuit is very simple, the Atmega8 do all the work, there is just some resistors and zeners to meet the standards for USB protocol, the oscillator crystal and some filtering caps

Hands-on jobs like these are where some of the the worst U.S. talent shortages exist, according to Manpower Inc., which recently surveyed more than 42,500 employers worldwide. In a weakened job market, the overall percentage of U.S. employers struggling to find talented workers dropped by nearly half to 22% from 2007.But companies are wrestling with how to fill the ranks of technical and trade careers?particularly when it comes to enticing young professionals as baby boomers transition out of the work force. Another problem: As people live longer, flattening or declining birth rates mean there aren?t enough people to work and sustain the retired.

Instead of relying on the usual project wiring, Kris designed a custom Arduino shield for controlling an LED light bar. He was also kind enough to document the ins and outs of his process -
After many months of working on my Arduino based project, I decided to finalize my project by making my own custom PCB. At first I wanted to design a PCB that connected to the Arduino through a series of cables. After some thought however, I realized that a shield would be better because it would eliminate the need for cables.- Make a custom Arduino shield

PopSci has an interesting feature and video on making your own ammo, it's as simple as pouring it off a roof :)
About 230 years ago, molten lead that rained from the sky?historically something to avoid at all costs?became a clever new way to manufacture an important commodity: shotgun ammo.Precisely round pellets fly straighter, but casting each in its own 1/8-inch mold isn?t exactly mass production. In space, making them would be easy. In zero gravity, surface tension pulls any liquid into a sphere, the shape with the least surface area for a given volume. This is as true for molten metal as it is for drops of water floating inside the space shuttle. On Earth, the closest thing to zero gravity is freefall?falling objects experience weightlessness right up until they hit the ground.

Robotic Telepresence is the ability to transport yourself to a remote location without going there. It is similar to video conferencing but whereas video conferencing gives you only a small window into the remote world, Robotic Telepresence gives you a presence, instantly transporting you there and enabling you to move around, look about, and interact with people, objects, and the environment as if you are actually there.Our robot, named TiLR (pronounced Tie Ler) has an 8" LCD screen and a powerful Canon camera - providing you with live bi-directional video and audio. As such it brings you face to face with people and objects - and gives you the freedom to move about the remote world from the convenience of your PC - wherever in the world you may be.

Nope, we aren't sensationalizing anything -- that creature you see above really has made the streets of Liverpool its home. According to an in-the-know tipster, it's reportedly going to be stalking citizens and making all sorts of ruckus, possibly the kind involving pyrotechnics. So what's with England and these totally random stunts? First a full-sized UFO crashes in Potters Fields Park, now a gigantic spider shows up as part of La Machine. Be honest here: are any of you terrified?Filed under: Robots

There's really nothing great that can be done with Styrofoam other than not produce it in the first place, but in lieu of recycling it or throwing it away, one man and his son, inspired by this artwork, took 5 years worth of Styrofoam packaging and did the next most logical thing—built a giant robot.
Assembled from 5 main pieces sliced with a foam cutter and held together with silicon seal, the limbs fit the torso as if they're sitting on a shelf (requiring no additional adhesive for easy assembly/disassembly). Also of note: this styrobot only weighs 20 pounds.
