Combining online and offline: the future of cash registers

Monday, October 4th, 2010

futuristic cash register from IntelHate going shopping in person but don’t want to buy everything online? Consider the future of shopping where cash registers will not just be able to ring up your purchases, but be able to tell you what other items would match the sweater you’re buying that day….including a review of your past purchases.

Love the idea or hate it, that is the future of brick and mortar checkout. Combining the online catalog with a streamlined checkout process, the goal is to help you shop smarter, better and of course, more often.

Intel has a future generation register in development right now that does all of this, plus more. In fact, it is predicted that in the future you won’t even need to bring your credit card – your cell phone will be the method of payment and receipts will be sent right to your phone. Added bonus – no more lost receipts for returns and exchanges.

Take a look at this video that shows what Intel is working on right now:

How to Jailbreak an iPad

jailbroken iPadJailbreaking an iPad

If you have an iPad, you may be intrigued by the thought of jailbreaking it.

Jailbreaking a device permits you to install and use third party applications and utility programs. In the case of a jailbroken iPad, you would be able to then run apps like Adobe Flash which is not available through the Apple OS, or access files like you can on a PC. One app that caught my eye was the multitasking app which would allow you to run multiple programs without having to save/close them. Another great app called Wi-Fi Sync gives you the flexibility to sync your iPad with Wi-Fi – no plugged in USB required.

Of course, jailbreaking the iPad is not without risk (the number one concern would be warranty) but PCWorld.com has put together the definitive guide to jailbreaking your iPad. In fact, PCWorld’s guide is so complete, it even gives you instructions on how to revert back should you get cold feet (or have to go back).

Once you’ve hacked your iPad, be sure to avoid the iPad updates from Apple since your device can be reverted to the non-jailbroken state. Should that happen, you can jailbreak your iPad again after the update is installed.

Make an inexpensive & simple UV LED Torch

Thursday, July 22nd, 2010

UV LEDFrom our friends at instructables comes an easy project for use with UV LEDS.

To make this simple project, here’s what you’ll need:
2 Ultra Violet LEDS
1 1/4W resistors (the value of the resistor needs to be calculated based on the forward voltage of the LED you use)
1 non-working 9V battery (or a 9V battery clip)
1 new 9V battery
Pliers
Solder
Soldering equipment

UV LED torchThe full instructions on the Instructables site will show you how to put everything together. Once assembled, the light snaps on to a working 9V battery to function.

Keep in mind, you don’t have to use UV LEDS for this project – you can use any color. Just adjust the resistor required based on the forward voltage and forward current of the LEDS you choose.

Buying LEDS without specs or you don’t remember the specs of the ones you have sitting around? Assume a max of 2.8V – 3V and 20mA. I would think high intensity white LEDS would work really well for this project.

I haven’t put this one together myself yet, but I think a few of these are coming with me on my next camping trip. Nice way to light up the tent and the ‘facilities’ late at night. Fun project – and you probably already have everything you need right on hand.

How to Make Your Own LEDS? Whooooooooa

Wednesday, March 10th, 2010

I found this how-to today on the great Popular Science web site.

Now that I’ve read through the article – I am amazed that I’ve never seen these instructions written up before.

Theodore Gray, who authors their popular “Gray Matter” column, gives the full scoop on the basic materials used to construct LEDS and provides the basic instructions needed to see just how LEDS work.

OK, it is not so easy to find some synthetic silicon carbide (carborundum) laying around, but surely everyone could get their hands on some sandpaper, needles, a 9V battery and a snap. Follow his instructions, and VOILA…you’ve recreated the basic principles behind the creation of LEDS.

This one’s a keeper.

Circuit Bending

Tuesday, September 30th, 2008

Have you ever taken apart a kid’s electronic toy to see how it worked? Maybe tried to cut the wires or rewire the circuitboard? That’s how circuit benders begin their hobby.

Circuit bending is the creative, short-circuiting of electronic devices such as low voltage, battery-powered guitar effects, children’s toys and small digital synthesizers to create new musical or visual instruments and sound generators.

One of the most popular toys to circuit bend is the “Speak n Spell”. Here’s a great demonstration of circuit bending featuring a Speak n Spell:
