Computer on a Stick

Intel is coming out with a 'Compute Stick' that is a full personal computer. It is about the size of a USB memory stick. On one end, the device has a full-size HDMI plug which attaches to your TV or monitor. On its side is a microUSB port which plugs into the wall for power using a standard USB cable. A second, full-size USB port allows you to attach peripherals and a microSD card slot provides for memory expansion.

Not to get too technical, but it is a quad-core Atom-powered mini PC with 2GB of RAM, 32GB eMMC storage, running Windows 8.1. The price when it comes out later this spring should be about US $150.

It also has a power button, and in addition to its USB port, it can pair with a keyboard and mouse using Bluetooth. Since Bluetooth sends a signal to about 30 feet, you can sit in your easy chair and have the best of TV and PC on one device, with no extra wires or gadgets. It also supports 802.11n Wi-Fi for connecting to the Internet and your home network. Now you can have a real PC TV with a keyboard, etc. No longer necessary to send YouTube videos from your PC as they are already on the screen. Am very sure I need one of these and hope by the time it is available I will be able to explain/justify to myself why.

New Mini Computers

The drive is on for TVs to get larger and computers to get smaller. Last year Intel introduced Edison, a computer the size of a postage stamp. This year it introduced a new model called Curie, which is so small that it could be built into a button on a shirt.

Curie is based on the Quark SE core, Key Features:
• A low-power, 32-bit Intel® Quark™ SE SoC
• 384kB Flash memory, 80kB SRAM
• A low-power integrated DSP sensor hub with a proprietary pattern matching accelerator
• Bluetooth* Low Energy
• 6-axis combo sensor with accelerometer and gyroscope
• Battery charging circuitry.
It is for both the wearable fitness market and biometric and security applications, with additional tie ins to other brands like Fossil (watches) and Oakley (glasses). Unlike TVs, when it comes to computers, smaller is better.

Bluetooth Symbol

Have you ever wondered how the bluetooth symbol was developed? Look at the top line on your smart phone to see it.

It comes from the Nordic runes for the letters GH and B for Harald 'Bluetooth'  Gormson, the king of Denmark and Norway back in the nine hundreds, who turned the Danes to Christianity. The name suggests he had a dark or blue tooth.

Five Microwave Facts

A common myth surrounding microwaves is that you can not put metal in them. The walls of the microwave are metal. You put metal in when you cook things like hot-pockets in those sleeves they come with (lined with aluminum, which heats up and browns the crust via convection). Some even come with a metal rack for double deck cooking.

A microwave oven’s radiation does not cause cancer, because it is not ionizing radiation. Even mice that spent their whole lives exposed to low levels of microwaves at the same frequency as a microwave oven, showed no adverse effects from the microwaves.

Devices like your wireless router, GPS satellites, Bluetooth devices, and smart phones also likely operate using the same band as your microwave oven. This is also why when you run your microwave, you may notice those wireless devices stop working well when you get too close to the running microwave. Some fractions of the microwaves from the magnetron are escaping and interfering with the signal your devices are using. The amount is too miniscule to be noticed or felt if you stand in front.

There is nothing special about the material the window of your microwave is made of. It is typically just plastic or glass. What stops the microwaves from cooking you is the metal mesh that is on the inside of the plastic or glass. The holes in the mesh are smaller than the wavelengths of the electromagnetic radiation your microwave is producing. The microwaves bounce off and back into your microwave oven to heat the food.

Many microwavable foods have a recommendation that you let the food sit for a few minutes before eating it. This is because sometimes the food is very thick and the microwaves may not have managed to penetrate deeply and so the center may not be warm, but is surrounded by a very hot outer layer. By waiting a few minutes, it allows the hot part to warm the center and the overall temperature of the food evens out. This is also why when you click “defrost” on your microwave you hear it periodically kicking on and off. It heats the frozen object for a short period and then lets the heated part warm the inner part by convection.

Mini Printer

It is the size of a computer mouse. PrintBrush is the smallest printer in the world. It is Powered by rechargeable batteries and wirelessly connected via Bluetooth. It can be used on any surface and prints full 8 1/2 by 11 pages at 600 dpi. It also features an optical sensor that helps to ensure a high image quality. Cool stuff should be available the beginning of next year for $199.
