Many city cyclists struggle to get themselves noticed as they do battle with cars, buses and lorries. But not any more, meet the Hornster ... a bicycle equipped with a horn that is louder than Concorde.

At close quarters the Hornster bicycle emits 178 decibels; a level of sound so powerful that if used in anger it could deafen any motorist who veered too close.
 
The Hornster bicycle was developed by the Environmental Transport Association (ETA) to highlight the dangers that cyclists face on city roads. Trucks are involved in over half of cyclist fatalities that occur in London.

The triple air horn fitted to the bicycle is an Airchime KH3A from an American locomotive, which has been adapted to run off a scuba diving cylinder. 

For most people, testing their new iPad 3 might involve looking at images on that high-resolution screen or seeing how fast the internet access is -- bit not for Richard Ryan.

Instead the gun-owning Apple fan decided to shoot his new gadget with a series of weapons including a Tech Assassin HK53 assault rifle.

His resulting slow-motion video -- filmed on a shooting range -- shows the iPad 3 being set up and them targeted with the guns.

When the first weapon doesn't quite do the damage Ryan was hoping for, he opts for something with a little more firepower. The result? An iPad no amount of AppleCare could help.

Digital cameras seem to be getting smaller and smaller -- but this is just ridiculous. Meet the world's smallest camera!

Balancing on the end of a finger it's clear to see the camera is small, however it's still fully functional and boasts a 2 megapixel sensor for photos and video.

Measuring just over one inch in all dimensions and weighing only half an ounce, the £65 camera appears to require Lilliputian dexterity, but retailers insist it's easy to use.

A spokesperson for Hammacher Schlemmer said of the diminutive device: "A human finger can snap a picture with a touch of the shutter button.

A US woman found out the hard way why you shouldn't buy an iPad 2 in a McDonald's car -- she paid $180 for a piece of wood painted to look like an Apple device.

22-year-old Ashley McDowell says she was approached by two men as she went to buy a burger from the store in South Carolina and they said they were selling iPads.

The men claimed to have bought Apple iPads in bulk and were selling them for $300. they then showed her a working model and agreed to sell her one for $180.

But when she got her new iPad 2 home, she opened the FedEx box she had been given and discovered it contained a piece of wood painted black with an Apple logo. 

In a bid to get more men into the supermarket, a Sainsbury's store in Kensington, London, has fitted iPad docking stations onto their shopping trolleys.

It's said this means blokes don't have to feel disconnected while doing the grocery shop and could even keep up-to-date with the latest scores by streaming football matches.

The high-tech trolley -- which could be rolled out to other stores if successful -- features a tilting iPad holder and speakers mounted to the handle.

Anticipating iPad using shoppers could find themselves distracted the trolley also has a front bumper with a sensor which lets off a warning beep if you get too close to other shoppers.

Apple have today released the official prices of the iPad 2 which goes on sale on Friday -- and they are a lot cheaper than this one.

That's because Apple have set prices of £399 to £659 for their versions of the iPad 2 and this one comes in at a whopping £5,000,000.

It's been given the bling treatment by jeweller Stuart Hughes who created a  24ct gold back with 53 individually set sparkling gems making up the iconic Apple logo.

The front - which normally only comes in black or white - is made from Ammolite, 75 million-year-old rock which has been finished with T-REX Dinosaur’s thigh bone.

If you are set on spending £5m on an iPad 2, but don't fancy the diamond home button, you could always buy 12,531 of the basic 8GB wifi only iPad 2, or 7,587 of the 64GB 3G version.

A man who returned his iPad 2 to Apple along with a note saying "Wife said no" has been given it back free of charge, with a note saying "Apple said yes".

At least that's the story currently doing the rounds after it was posted on MacRumours and picked up by several news outlets.

Apple keep a record of the reasons people give if returning a product to an Apple store and it's claimed this one was circulated by amused employees.

When two Apple VPs heard the story they are said to have decided to ship the iPad 2 back to the customer as gift along with the "Apple said Yes" note.

While it's a great story if true, we're not sure if we believe it… and neither will your wife if you tell her Apple gave you your new toy gratis too.

A bizarre iPhone and iPad app which digitally helps gizmo-wielding Catholics to confess has been officially approved by the Catholic Church.

"Confession: A Roman Catholic App" has been designed to be used in the confessional and guide sinners through the process.

In addition to logging how long it has been since their last confession, the £1.19 app provides a step-by-step guide to the sacrament and prayers.

Makers are keen to stress the app is not designed to replace confessing before a validly ordained Roman Catholic priest… because then if your iPhone crashed you would go straight to hell.

Just because the iPhone is one of the most technologically advanced communication devices known to man, doesn't mean it has to look it.

At least that's the idea behind a new case which is designed to make your Apple gizmo look more like a 1980s-style handset.

Makers Thumbs-Up say they hope the retro styling of their £12.99 80s iPhone Case will be a hit with phone users who are looking for something a bit different.

After sliding their iPhone into the retro holder, users have a device which looks like it could have come straight out of Del Boy's hand, but still has all the mod cons.

And because the iPhone can sometimes have a dubious call quality, your shouting into the handset just makes the whole thing look more authentically 80s.

A Chinese Canadian inventor who impressed the internet by creating a water-powered jet-pack says it is now due to go on sale.

The JetLev device can power a user 30ft into to air and allows them to travel at 22mph across water by  constantly sucking it up via a hose and then blasting it back down.

Users control the thrust and direction via an arm which hangs over their shoulders from the light weight backpack.

Raymond Li - who spent 10 years perfecting the device - says it's finally ready to go on sale for £60,000 each and sure to become a must-have toy for  fancy holiday resorts

But he also reckons the JetLev could also be employed in search and rescue missions. Unfortunately it won't be any good for your daily commute… unless you're a fisherman.
