In my recent post about the “Canon MP190 series reset guide“, I’ve receive many question on how to set the printer into service mode which is needed in performing the Ink waste reset.   For those who still don’t get it, just watch the video below for better understanding.

Here are steps:

1. Press and hold the stop/reset button

2. Press and hold the power button

3  Release the stop/reset button and press it twice.

Robot Assistant Deployed at Fukushima Daiichi nuclear plant

Posted on 21 March 2011 by yizhan

A robot named Monirobo (Monitor robot) was deployed in Fukushima nuclear plant in japan. What does this robots do?  Well it was said to help workers at the nuclear power plant  in monitoring the radiation level. The 5-foot, 1,300-pound Monirobo has a robotic arm for collecting samples and moving obstacles, and it drives using a pair of treads. It is designed to go where humans can’t, using a radiation detector, four video cameras with 3-D capability, and temperature and humidity sensors. The  robots  was developed by Japan’s Nuclear Safety Technology Center in association with the Ministry of Economy.

The robot has two version, the red and yellow.  The red was design to detect radiation level while the yellow has different functionality. The yellow one is designed to collect dust samples and monitor flammable gas.

Its good to know that finally Japan is starting to move up and using all their technology to recover from the earthquake that brought disaster to their people.

Cafe-Manila Pro Review

Posted on 08 March 2011 by yizhan

Cafe Manila Pro is an internet cafe management software that delivers advance feature to provide all your administrative needs in operating an internet cafe. It has a detailed and friendly user interface for easy operation.  The simplicity of its design makes it easy for the user to operate the software.

Most of the time, customers ask how much time did they consumed or how much time  is left, well its not a problem in Cafe Manila Pro.  When you click on each active account, a window on the right side will display a billing summary of the selected account, making it easy for the operator to see some details of the selected account.   It also has a full list of the product on the side, which  you can just drag from the list to the active account and the product will automatically be added to their bill.


A graphical view is also available in Cafe Manila Pro which you can arrange the client pc in the graphical view according to its physical position . I think there is also a feature that you can add your own floor plan as background image in the graphical view.

Want to see what your customer is doing? With the screenshot view, you’ll be able to monitor what they are doing to your pc. This is very useful for large internet cafe.  Multiple screenshot are shown on the panel, you can enlarge the screenshot by right clicking on it and ticking the “open screenshot” button.

Pricing structure, security, and application profile are all connected to a user group.  With this feature, you can customize how you want to log in a user.  You can categorize  pricing structure  the way you want by selecting either basic pricing or advance pricing.

I find the advance pricing very useful because I can set it to my desired price.  Let say I have a 3hrs straight promo for Php50 and my rate per hour  is Php20, so what I’ll do is add an advance pricing of 180 minutes and put Add to Bill -10.  This mean that when the user reaches 180 minutes or 3hrs, instead of having  a total bill of Php60 since my rate is Php20/hr, it will be deducted by Php10 to make it  Php50.

The security setting of Cafe Manila Pro has many option. Its just like tweaking your client pc.  You can  disable/enable internet functionality,  download, hotkeys, and hard drive.  You can also prevent client from accessing vital functionality of windows such as control panel, explorer, and task manager.

There is one thing that I like most with this software…… Its the after sales support.  I have tried many cyber cafe management software and I think cafe manila pro got what I want.

Integrated Circuit

Posted on 05 March 2011 by yizhan

Integrated Circuits also known as ICs. A reduce size, weight, and power requirements of modern electronic equipment.  From vacuum tube to transistors, and now IC’s .  ICs are actually microelectronic circuits.  It contains small electronic components such as diode, transistors, and capacitors which is visible only to a microscope.  There are two classification of an IC,  Linear ICs and the other one is Digital ICs.

Digital ICs

Digital ICs are use in computers, microprocessors, memory chips, calculator, and digital  clocks as well as many other digital device. Digital ICs process only on/off signals or using binary mathematics to process “one” and “zero” signals.

Linear ICs

Linear ICs are use in analog type circuit like audio amplifiers, voltage regulator, operational amplifiers, and some radio frequency circuits.  Most linear ICs are low-power device with power dissipation rating lower than 1W.

History of ICs from wikipedia

Early developments of the integrated circuit go back to 1949, when the German engineer Werner Jacobi (Siemens AG) filed a patent for an integrated-circuit-like semiconductor amplifying device [1] showing five transistors on a common substrate arranged in a 2-stage amplifier arrangement. Jacobi discloses small and cheap hearing aids as typical industrial applications of his patent. A commercial use of his patent has not been reported.

The idea of the integrated circuit was conceived by a radar scientist working for the Royal Radar Establishment of the British Ministry of Defense, Geoffrey W.A. Dummer (1909–2002), who published it at the Symposium on Progress in Quality Electronic Components in Washington, D.C. on May 7, 1952.[2] He gave many symposia publicly to propagate his ideas. Dummer unsuccessfully attempted to build such a circuit in 1956.

A precursor idea to the IC was to create small ceramic squares (wafers), each one containing a single miniaturized component. Components could then be integrated and wired into a bidimensional or tridimensional compact grid. This idea, which looked very promising in 1957, was proposed to the US Army by Jack Kilby, and led to the short-lived Micromodule Program (similar to 1951’s Project Tinkertoy).[3] However, as the project was gaining momentum, Kilby came up with a new, revolutionary design: the IC.

Robert Noyce credited Kurt Lehovec of Sprague Electric for the principle of p-n junction isolation caused by the action of a biased p-n junction (the diode) as a key concept behind the IC.[4]

Jack Kilby’s original integrated circuit

Jack Kilby recorded his initial ideas concerning the integrated circuit in July 1958 and successfully demonstrated the first working integrated circuit on September 12, 1958. In his patent application of February 6, 1959, Kilby described his new device as “a body of semiconductor material … wherein all the components of the electronic circuit are completely integrated.”  Kilby won the 2000 Nobel Prize in Physics for his part of the invention of the integrated circuit.

Robert Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. Noyce’s chip solved many practical problems that Kilby’s had not. Noyce’s chip, made at Fairchild Semiconductor, was made of silicon, whereas Kilby’s chip was made of germanium.

One of the most advance integrated circuit are the microprocessor or “core”.  It is responsible in controlling  modern digital device such as computers,  cellular phones, and some digital devices. The performance of ICs is high because the small size allows short traces which in turn allows low power logic  to be used at fast switching speeds.   Migration of the ICs in a smaller scale had been consistent over the years, allowing more components to be place in one single chip.  The number of transistors in an integrated circuit doubles every two years. As the feature size shrinks, almost every function and features  improves.
