Ok, we are all used to different types of calculators powered by batteries, solar powered etc. In fact most of people nowadays, don’t use calculators, but cell phones for simple calculations.

But for all calculator lovers, we have a type of calculator you haven’t seen before. It is powered by water, and here it how it works:

Just add water or any other electrolytic liquid into its fuel cell and the chemical reaction between its zinc anode and cathode produces an electrical current that will power this Water Calculator for a month before it needs another sip.

Great idea, wonder if it can be implemented in some other devices?

The price is $19.99 at Computer Gear

D:Scribe is a digital fountain pen, designed by Reuben Png, that allows users to send SMS and email messages from paper. Just write out the message and circle the person’s name to send. You need to have Bluetooth enabled phone, and of course the surface to write on. Once a message is sent, the status is displayed on the built-in OLED screen. Sounds interesting to me, but we’ll see if there will be any interested companies.

Here we have quite interesting spy gadget. It is a picture frame with built in microphone that you can call with your phone and listen to what’s going on in the room.

This larger sized picture frame (which you can add your own picture to) may be hung on a wall in a room of your choice. You can then dial the number of the GSM bug built into the rear of the frame - the call will connect silently after two rings and you will be able to hear whats going on in the room…from anywhere in the world!

The price is 250$ at this store.

Today I came across this very cool gadget - the Laser Stars Projector. What this gadget does?

It’s a unit about 10inches tall that projects a combination of green laser stars and blue (slightly ultraviolet-ish blue) clouds onto your ceiling, walls, pets, etc. Both the clouds and the stars are constantly moving and morphing, just like a proper Universe should. And there are literally thousands of green laser stars to look at. There are two ways you can adjust your Laser Stars Projector, first you can pivot the projector itself 180 degrees horizontally around the base so that you can control *where* it is projecting in your room. It can literally fill up an entire ceiling and portions of several walls at once. And the other thing you can adjust is the intensity of the blue gaseous clouds, from zero to full intensity.

Here are some features:

 

Uses Green Laser and Holographic technology

2 built-in precision glass lenses

Creates thousands of stars with or without blue cloud formations

Ac Adapter Included (US Only - 120V)

Unit Dimensions: 10″ tall x 9″ wide x 7″ deep

The photos can’t show you how cool this thing actually is. And it can be quite romantic also
