In this site, I'm trying to show some handicraft of me.
At first, I apologize to the guest of this page.
Because of I'm not a native English speaker, the English page is a small essense from Japanese page.
You may not able to understand by it's shortened story and my broken English.
And the translation is just starting and I am lazy.
I will show some handicraft of me.
I made some, but only a plan for many. Some of them may be a plan of make-believe.
I made some pages by salvaging from my old note. Then some story is very old.
If you try to make them, you should do it by your own risk. Some one may have a hazardous problem.
And I think many of them are not suit for a child. It will require some skill.
Photos shows the basic structure of my infrared thermography.
The radiant heat is collected by the parabolic mirror to the thermal color changed surface. The surface can be seen through the hole of mirror.
The color change at 60 degree Celsius of target temperature.
I made a kind of axial air gap generator.
To reduce a magnetic resistance, I use the core in the coil.
To reduce cogging torque, I select the numbers of each magnet and coil.
For converting from many phase to d.c., I use full-wave voltage doubler.
