I make a home security system at my house by myself.

The core technology of this system is a super-classic communication protocol whose patent right had already expired. However this is useful for my system.

The plat home is the Windows XP whose network connection is cut from the internet perfectly. However the devices of the system become to drop from exhaustion.

The system reliability becomes law and down day by day because of the series of the devices faults.

If I get buy new one, there is no problem. However the distributor in Japan becomes not to deal with the device.

If I try to import them from abroad, I don't like to pay the additional fee. Then it is doubtful that the devices work well in Japan, because the specification of the device may not fit with Japan.

Therefore I am thinking over another new system.

Thought I can finish the concept of the system, recently, I am going to feel

"Too much of a bother"

At every weekend, I have to spend my time for writing columns. Moreover the time is needed for not only system construction but also the maintenance.

In addition, I have to get a special instrument for the system validation. Though I sent mail to the maker company, unfortunately I cannot get reply at all.

I have just asked the company with this line “Please borrow me the instrument for a month for free. I am not going to destroy it".

I think that

"They don't want to build up the relationship with me."

There seems to be no company that wants to make the relationship with me, as opposed to an organization I belong.
