Kind of Blue - World of fountain ink.

I never intended to get into anything other than audio, but...

In this age of COVID-19 disasters, I thought it might be good to immerse myself in another world for a little while. And now, I'm reexamining the world around me.

Now I'm becoming obsessed with fountain pen inks.

This is a "Pelikan Royal Blue" that I owned a few years ago.
It is a standard dye ink made in Germany, a very nice blue, and I was inspired by this color. (The top line in the photo above is this ink, a vivid blue with a purple tinge, but the exposure doesn't do justice to the color in this photo.)

Fountain pen inks have evolved to such an amazing degree that I am stunned by the state of modern inks.

Sailor's pigment inks, pure black "Kiwaguro", blue black "Seiboku" and "Souboku", have been my personal standard for the past seven years.

I was convinced that the current pigmented inks were good enough because they solved the critical problems of water resistance and ageing of fountain pen inks. The reason why I can use fountain pens normally for business purposes is because of the commercialization of pigment inks with ultra-fine particle nano technology.

So I never thought of going back to the origin of ink, dye ink.

But now, what kind of dye ink should I choose?

I tried to choose a few variations of blue ink based on the ink images posted on the Internet.

There, I found Sailor's ink series "SHIKIORI" . It had as many as 20 color variations, and the exquisite naming was very enjoyable.

In the end, I chose the blue inks "Souten" and "Yamadori", which have slightly different color tastes.

Here is a comparison of the two inks. Written with Sailor "Fude DE Mannen" (nib angle: 40 degrees).

Pelikan Royal Blue is a graceful purple-ish blue, Souten is the color of a clear early summer sky, and Yamadori is a deep green forest rather than blue.

Once again, I fell in love with the beauty of Pelikan Royal Blue. And in the future, I think I will use "Soten" more often as a new blue ink.

I was convinced that the ink madness is gradually increasing. Once again, I realized the richness of human sensitivity.

I'm going to try to immerse myself in the world of blue pigment inks for a while.

P.S. Hopefully, those in power should make every effort to bring about a peaceful world we can all feel a little happier. Never destroy it easily. No war!

"Audio Tone Generator Lite" has been updated to ver 5.0 today.

"Audio Tone Generator Lite" is a high quality audio signal generator app for iPhone.

It will help you to make the sound benchmark for testing your audio equipment and loudspeakers, your listening environment and room acoustics or your hearing check.

With the latest version, the UI design has been revamped to a brighter and more visible image, and stability has been improved.

"Vibroscope Lite" has been updated to ver 5.0 today!

"Vibroscope Lite" is a vibration measuring app by using iPhone's acceleration sensor.

"Vibroscope Lite" is a free app that is simplified the measurement function of "Vibroscope".

This app can be intuitively detected an acceleration amount, that displays the two-axial coordinates in the horizontal direction and the time-axis waveform in the vertical direction.

It can measure by determining the horizontal or vertical direction to suit the attitude of the iPhone automatically, so as to be available on the floor and desk or handheld.

The peak value of vibration acceleration can also be displayed in the "GAL" unit used in seismographs.

New updated - "Vibroscope" ver 5.0 - Vibration Level Measurement and Analysis Tools

icon-vs_v500.png

"Vibroscope" has been updated to ver 5.0 today!

"Vibroscope" is a powerful vibration measurement tool to analyze various vibrations in real time using iPhone's acceleration sensor.

It allows you to monitor by visualizing the very low-frequency vibration such as inaudible by ear.

This app can detect the amount of acceleration of vibration and display the two-axis coordinates in the horizontal direction and the time-axis waveform in the vertical direction.

It is also equipped with the ability to analyze the frequency components of the very low frequency vibration by FFT analyzer.

In the latest version, the UI design has been renewed and the FFT graph display method has also been changed.
