Cats had been recognized as the most commonly pet in household.

According to the pet survey, cats and dogs are the top two favorite pets that mostly rear by peoples in their home. The reason why peoples love these two kinds of animals, is mainly related with the loyalty for their master (dogs) and the elegant and its always laid back behavior (cats)

Having cats with a pet or partner is a pleasure experience, as we can learn their daily life habits, behaviors, body languages and their socialization. However, some of the cat lovers facing many problems rearing cats and this can greatly become a great headache for them.

Some of the matters that currently turn into major problems to cat lovers:

From now on, you can waive goodbye to the above matters with “Pet Porte“.

I’m known you must be wondered, what is this “Pet Porte” is and how can you fully benefit from this “Pet Porte“.

Well, this Pet Porte is a brand new and high-end technology, which is an awesome selective cat flap that work as sensor. This sensor can consistently senses your cat with their in-build pet ID chip implants.

What’s that mean is your cat can now free itself from the traditional yet old-fashioned collars. The PetPorte works accurately by just reading the cat’s microchip cat flap. Read more »

This is a small programmable device (similar to PLC) with 4 inputs, 4 outputs and full development system running under Windows.

You can write and test a simple program, with debug feature, then store such program in the device non-volatile memory and then, every time device powers up, your application starts autonomously. Project archive contains schematic, printed circuit board, HEX file ready to be uploaded to microcontroller and application program that runs on PC (Windows environment).

You always expect some of the important emails in your email account, but the waiting process makes you become even more nervous?

Kill the nervous today with this stylish twinkle star ambient email notifier.

Those materials that needed are:

• 4d-micro-USB module
• RGB LED
• RS-232 port
• Picaxe 08M
• COM port
• Python script

Firstly, you need to use a 4d-micro-USB module to provide the power resource. The RGD LED will be controlled by the RS-232 port through the Picaxe 08M.

One of the cool feature about this ambient email notifier is you can control the colors and the brightness. How? It’s all can be done by sending execution code to the COM port. Read more »

I know - COM ports are quite obsolete, it is still used in many embedded projects. This one is a simple serially controlled I/O board with 29 lines that can be configured to control anything like from stepper motors, relays and other automation appliances.

The board constructed around z8 microcontroller which is quire rare in embedded projects. Despite of 29 I/O lines serial I/O board has some special features like programmable pulse generator, incremental encoder switch input, 3 counter registers, I/O port memory registers. Each I/O line is LED monitored. To make control easier there is a Visual Basic Program Template available where you can set up easy interface to access all board features.

Alberto ricci bitti has a nice collection of amazing projects in his website. One of his designs is scriptable thermometer which can be programmed in basic like language within built in editor.

Design circuit is very simple four buttons, four relays, RS232 interface and graphical LCD connected to 8 bit COP8CCR9 microcontroller from National Semiconductors.

Scriptable controller has 6kB non volatile memory where custom scripts can be stored and executed. Built in ASCII interpreter can run scripts as custom applications. Author even provides two examples of scripts that can be run instantly. One of them runs controller as graphical thermometer while another as GSM cell phone connected vending machine. This design also was awarded as application of the day in national Semiconductors.
