Air admittance valve

Stick in a T piece with a valve to let air back in if the engine fails to fire. As mentioned before, you'll have to let the vacuum out before you can open the chamber.

to get from airport queue to airport queue really fast.

Posted in LOHAN ideas..

if the rod is an I section with teflon sliders that fit around the bottom flat bit. This and many more problems are solved.

Re: Ultrabook?

Did anyone else notice the "Small Cheap Computer" died out when they dropped the Cheap part?

Geoff Johnson

"any de-listings would be published "

Excellent, a directory of all the best free download sites.

Geoff Johnson

Not a Problem

Their streaming selection is rubbish anyway.

Hopefully all these issues will be fixed soon as Netflix is coming to the UK.

Geoff Johnson

Maybe there's another way...

Have two people carrying a box each linked by some wireless data transport mechanism. One person holds their box next to the victims pocket. The other person buys something at he supermarket and waves their box at the payment terminal. The two boxes relay signals from the card to the terminal and back. The terminal and card think they're in proximity and talk quite happily via the wireless link. Money goes from victim to legitimate retailer. Goods go anonymously to the bad guys to be sold on e-bay.

So, buy your RF screened wallet from Geoff's shielded wallet store now.

But the Peltier effect can be useful the other way around.

I'd guess that this will act as a heat pump if given power. These kind of things usually work both ways.

Geoff Johnson

OEMs and BIOS people

Has anyone asked the OEMs and BIOS manufacturers for comment on this issue? Surely UEFI has a configuration system like the old BIOS settings system, and surely there'll be an off setting in there.

Geoff Johnson

plenty of time to get saving

No problem there. Just bid an absolute stack of cash from your savings account, then use the car to go back and deposit a small amount in the account. Maybe a few lottery tickets too.

Mushroom

You've probably already considered this, but...

Put the vacuum pump tube near the top, then you don't need to go through the outer tube.

Get the temperature low before pumping out the air - the thermal conductivity of a vacuum is pretty low.

And as mentioned above, make sure your lid doesn't get frozen on. I've seen rigs like this blow their top due to frozen relief valves and it gets pretty violent.

Next Generation.

So will the Second Edition be SmartARSE?

Geoff Johnson
Thumb Down

Wimps.

Should have gone with the jet engines. If they're sticking a standard petrol engine in it, I won't be buying one.

Geoff Johnson
Thumb Up

I want one.

That's pretty much all I have to say really.

Oh, and a few General purpose IO pins would be nice.

Geoff Johnson

Another PC myth

On the IT front, they (well actually the other team on the show I believe) also tested whether a laptop in a bag can stop a bullet.

Geoff Johnson

Just short of breaking the sound barrier.

He beat thrust SSC by just over 2kph. Therefore he must have broken the sound barrier.

If only he could have gone the other way too, he would have the land speed record and two speeding tickets.

Geoff Johnson

Nautical instruments

What happens if you're looking for a sextant?

And I dread to think what happens if you want to do any analysis.

Geoff Johnson

Why not 2.5 bits per cell?

I'm sure it's doable, just a bit more logic around the edges.

Geoff Johnson

Readyboost

These mini USB flash things look like good devices to use for Windows Readyboost in a laptop. Just depends whether the speed is any good.

Geoff Johnson

What do we call it?

If a Binary digIT is a BIT, what's a Ternary digIT going to be called?

Geoff Johnson

Monitoring site

Is it just some cache thing on my machine or is the monitoring site 2 days out of date?

Geoff Johnson

E-Mail

Does this mean we'll finally be able to read e-mail with HTML in it?

Geoff Johnson

Rats

"the Iranian space programme is entirely peaceful in nature."

Unless you're a rat.

Geoff Johnson

Looks about right.

This is the ping time for my house to the server where the image is.

Geoff Johnson

Instruments

The Rover chassis has proved to be an excellent design but maybe some new tools would be nice.

Something (laser maybe) to vaporize rock, and a Mass Spectrometer would be nice. The mass spec could also sample the atmosphere to see where the methane is coming from. Above all, now we know the platform can last as long as the solar panels stay free of dust, let's add a feather duster.

Geoff Johnson

blackberry batteries

My blackberry has a removable battery so you can reset the phone when it locks up.

Geoff Johnson

Make some wheels sink.

Surely if they can't move it, they can at least make some wheels sink deeper by spinning them. Maybe that would allow them to tilt the rover towards the sun and keep it alive.

Then you have a stationary lander rather than a rover but it's still good for some of it's science work.

Geoff Johnson

RE: balance... #

The Harrier had a few little thruster vents in strategic places (I think they called them puffers), these were used as a fine balence control mechanism. I believe this new toy has a similar system.

Geoff Johnson

Planet X?

Pluto (formerly the 9th Planet) was stripped of it's planet status in 2006 so surely any Planet X would be Planet IX now.

Unless NASA are hiding two planets.

However many, we should be told exactly where they are so the astrologers can be more accurate. How many of us aren't buying lottery tickets because our horoscopes are not telling us how lucky Nibiru will make us this weekend. Not to mention how many get run over because they didn't know how unlucky they were due to be.

Geoff Johnson

html?

I notice they carefully avoid showing the e-mail capability. I bet it's still text only.

Also noticeably absent was a demo of the web browsing capabilities. But then there's not a lot of WAP compatible pages out there these days.

Geoff Johnson

home server

Lets see what the total system power consumption is. Hopefully I can get something sub 20W and replace my Geode system.

Geoff Johnson

Quick and easy sale?

They missed free listing day on eBay last weekend.

Geoff Johnson

RIAA

Rumour has it that the RIAA persuaded Microsoft to disable a PC's ability to record the audio it was playing. Looks like they need to persuade the rest of the world now.

Geoff Johnson

Could be good marketing

How many people have looked at that page who otherwise wouldn't.

Geoff Johnson

Nano lego?

From one of the links... "The tail is made out of 15,000 Lego bricks..."

That's a lot of bricks for 30 cm.

Geoff Johnson

HTML

Have they got HTML e-mail working yet?

Geoff Johnson

Understandable to announce this now.

Let the world (+ dog) know they've submitted it to Apple so the world (+ dog) knows if Apple reject it.

They proved it wasn't filmed in Nevada

Surely it was in Australia. That's where the tapes showed up.

Geoff Johnson

Welcome to our world.

Where an _already_censored_ image on Wikipedia can can cause half the country to be banned from editing articles.

Where a configuration blunder by an ISP can block the whole internet archive.

Where we live with it all for the sake of the anti-terrorist industry.

ICESat should help slow the melt.

Ice melts much faster when it's broken up to expose more of it's surface to the elements. Therefore we can slow the arctic melt by stopping Icebreakers full of scientists from cruising around the place measuring things.

Geoff Johnson

Iceweasel

To use on-line banking I had to install the user agent switcher plugin. The Debian bunch seem to like to put barriers in the way of mass adoption. But on the other hand it's about the most stable platform I've tried.

Geoff Johnson

Rules killed it.

The stupid 80 HP power for 6 seconds rule renders KERS pretty much redundant. To encourage innovation, there should be no falsely imposed limits.

BTW. The brake balance problem comes from the way the batteries are charged by using the motor/generator as a brake on the back wheels. Once they're charged you suddenly find you're braking with the front wheels far more then the back.

Geoff Johnson

"a study by UK government advisers"

They can safely make up the figures knowing that the Government won't actually bother reading it anyway.

Geoff Johnson

Dissapointed.

From the headline I thought HP were going to start employing Teenage Mutant Ninja Turtles.

Mobile phones.

The mobile people just agreed to standardize their USB ports. Now they can all change them for different USB 3.0 ones and protect their car charger markets again.

Re: google squared

Try putting 0.1 into that.

Geoff Johnson

Not as dangerous as it looks.

When I worked at a university it was common practice to dip your bare hand in liquid nitrogen and throw a handfull at a colleague. As long as you don't hold your hand in for more than a few seconds it doesn't even hurt. The person you throw it at gets a bit cold and damp as the nitrogen condenses water from the air.

The liquid boils into a gas as soon as it comes near a warm hand so you're only in contact with the gas. The gas is still pretty cold though (-195 C) so will freeze you if you hold your hand in there long enough.

The main problem I can see with this kit is liquid nitrogen is good for getting things really cold, but it has a low latent heat figure so it doesn't take much energy to boil it away. I can't see this pulling much more heat from your CPU than a good water cooling system would.

At last

A hulu story that looks like it's done some research and realised it's only a local site for americans.

Geoff Johnson

WWW

At least You Tube is international. Hulu is just a little local site for Americans.
