This piece of kit is a robot that is powered by slugs. It searches for slugs and places them into it's fermentation pod in order to power itself. The creator said he planned to make a larger model powered by rats that could run about indefinately in the sewers. I'm not sure how far along this project has gotten...
-Standalone ADSL (ie not connected to the work network/firewall) to allow you to pull down drivers/updates/apps
-Mini toolbox & multimeter (depending how much you get into hardware repair)
-spare *working* parts to help the process of elimination with faulty hardware.
-Cans of air to clean parts
-Second monitor/keyboard/mouse so you can work on two separate projects without have to muck around with a KVM
Check out an apple keyboard. You plug the mouse into the keyboard; the keyboard into the computer. Mac monitors have USB hubs built in, so you could plug the keyboard into that.
That way you cut down the amount of cables going into the back of your computer.
When it comes to something as risky as space travel I'm still in the belief that it's better to go for a simpler approach. Like the guy said, and I quote:
"It's just too complicated. I know from flying it four times"
To me it seems the US has gone back to the K.I.S.S. (Keep It Simple, Stupid) strategy that the Russians have always adopted. To me it never made sense to have the shuttle strapped right next to the fuel and solid rockets. I believe it wasn't ever intended to in the original design...
This way they'll be able to have an escape capsule thus giving them half a chance in the case of a launch error. The shuttle is amazing, but the sooner it's retired to a museum, the better, IMO.
The blades of a helicopter rotor are only effective at a set range of speeds. It's not as simple as "just turn the blades faster". Much like a propeller for boats...
Also, you don't seem to have thought about the opposite side. Imagine the same example you give with the heli doing 100kph with a rotor with tip speeds of 100kph also. The trailing rotor has an effective speed of 0kph, but the leading blade (going into the wind) has an effective speed of 200kph. This will cause the helicopter to flip upside down or even go into a spin. Either way, it's messy.
The only solution is to have dual counter-rotating rotors and to increase the rotational speed of these rotors as airspeed increases (at Mu, the effective lift of the dual rotors will halve).
I never had to use a computer for anything properly useful (reading, writing, etc). I remember when I was at school lessons involving computers were never useful and always considered a cop-out as by the time the (usually non computer-literate) teacher had got all the kids sat down, and after all the 'problems' (kids closing the apps, screwing around) had been fixed, three quarters of the lesson had been wasted. Word processing is a different matter, however, but most people have a computer at home these days and shouldn't really need to spend much time on typing lessons or anything; there seems to be such an influx if ignorant kids/young people these days it concerns me deply that society is failing these people (parents are easily the #1 cause of this, I'm sure).
I think lessons on how to use a computer are important since they play such a huge part of today's society, but all this talk of lessons on a computer or even over the net is, in my view, poppycock.
The first time computer use was genuinley useful for me was at A-level when I studied computer science.
How about a CO2 and O2 sensor pair that checks to make sure breathing is still going on?
So if your kid stops breathing you can be informed when you're 50 miles away and unable to do anything... well handy.
I'd rather just have a nanny watching the kid so they could call an ambulance/do some CPR if the above nightmare does occur.
It'd be better to have a call saying there's a problem but the ambulance is on the way instead of getting some message the kid's not breathing, then having to ring whoever's in charge to find out if it's an equipment failure, etc etc....
You can buy cheap wirelss cameras complete with receivers for very little cash these days. Some are good for night vision and have IR LEDs so you can watch the kid at night. I don't see why you would ever need to watch your kid on your phone or anything, just get a decent babysitter and she can call you in case of emergency.
Sometimes you can go overboard with technology, you know!
I just bought a 64bit computer with a 17" flatscreen monitor, 512RAM, Bluetooth, wireless and a seriously good OS for £700. It's called the new iMac, btw and I think it's a very reasonable price for what you get. They were even doig a special offer where I got an HP printer for £5, normally they're £70+.
Macs really aren't expensive any more, it's a myth.
Yeah, but those cigarette lighter jump leads aren't all that good. The starter motor of a car takes the largest current of all components within the vehicle, so much so that the usual path of cable in a car goes:
Battery -> Starter motor & solenoid -> everything else. The cigarette lighters take very, very little current in comparison (you can power one from your PC's power pack! ) and the circuitry leading to them is normally only of the guage required.
It is therefore very easy to burn out a chunk of your car's wiring loom or a fuse by using these dodgy jump leads.
Also think about it, who's going to know the correct procedure for jump-starting a car but not know where the battery is?
The idea is there and it's good to think outside the box, but sometimes the box is there for a reason so it may be a safe idea not to stray too far outside the box:)
The fact of the matter is, a low cost cruise missile with a payload of anthrax or whatever could easily be made using off-the-shelf components of model aircraft (you can even buy model turbine jet engines). Bruce here is simply showing that it is possible to do so.
0-60 in 3 seconds for $1m or $30,000?

· Score: 3, Interesting
Check out these babies . They can do 0-60 in a mere 2.9 seconds, that's actually 0.1 quicker than the bugatti!
They're powered by two bike engines working together to give a power to weight ratio of 600BHP per tonne, and the amazing part is they only cost around 16,000 although some assembly is required. Top speed isn't close to 250+mph, but do you know anywhere where you could get to that speed (UK driver speaking here!)? These certainly win the 'bang-for-buck' award here, and are available to joe avaerage...
for FPS games.... If this thing could be tweaked to provide an image for your entire field of vision it would be far superior than those nasty goggles that were used in 'Virtual Reality' systems a few years back. They were simply screens right infront of your eyes. Desert combat and the like would rock if you could use your peripheral vision. It wouldn't be much harder to sense if the eyes have moved and could allow the user to see larger images if they could look to the left and right and have the image scroll along...
Would be interesting to find if it gives headaches to the users like CRT monitors do these days..
Firstly, at the time of writing an ark the size described would have been impossible to build due to the building materials available. Only wood was used and an ark of biblical proportions would simply fall apart.
Secondly, there's not enough water on the planet to cover the entire earth, especially to the height of a mountain!!!
It has been found that noah was infact just a trader and that the 'flood that covered the earth' was simply the local river flooding. The story has been basically dramatised for the bible.
What a waste of time trying to find the thing...
A man designed some specs that used this technology in order to provide clear sight to the poor masses in Africa. All he did was have two syringes - one for each lens- and he adjusted the lens by pumping in/sucing out liquid as the person looked at some images, then he unplugged the syringes and a valve kept the liquid in and the glasses set to the same level.
It's kind of a one-pair-fits-all system where the vast majority of people that needed glasses could use this one system. They sure weren't hot to look at, but no-one gave a crap because people aren't so vain over there!
This certainly isn't a new technology.
I'm not sure that it would be able to do anything useful, I mean, it has spheres for hands and is only 39cm tall! Try stapping some basketballs around your hands and see how much useful stuff you can actually do...
Also, doesn't anyone find it a little sad that people are looking for robots to perform menial tasks such as fetch them a beer? Why not research better vehicles/bots for exploring other planets, or for more effective bomb disposal, maybe create intelligent limbs/organs to replace those that the handicapped/injured require? Why spend so much time and effort on research just to allow the human race to be even lazier? There's so many overweight and unhealthy people that are putting a strain on the health systems of various countries, why allow these people to be even lazier?

However, like the space race, we try to ignore what the russians managed to do first, eh?
Stevo said apple would be at the 3GHz mark a year ago... looks like IBM aren't coming up with the goods.
...is to give it the ability to smoke: Smoking bot
A Mac is a personal computer, so it is actually correct. The PC/Mac differentiation is common although incorrect, strictly speaking.
That scrollwheel with the button in the center sure looks like the iPod one... I wonder how apple feel about this.

no need for a tail rotor as the two main rotors rotate in opposite directions, much like the kamov hokum:
http://www.helis.com/Since80s/h_ka50.php
Counter-rotating rotors also allow heli's to fly a lot faster as you don't get the problems with retreating blades stalling.
