I made another FM transmitter. Old components from a 1986 Mitsubishi VCR were used.It is a 3-transistor circuit. Only FM mono is transmitted.This is the transmitter. ベイブレード

ベイブレードI have built an FM transmitter.Previsouly I have built an AM transmitter but it never worked right, only very short distance.http://cappels.org/dproj/FMXMTR/fmxmtr.htmThe design is somehow finicky, and does not work like shown.…

1. USB GizmoIt can show japanese characters! Individually programmed 5120 bits.There is a software on the Windows PC side too. Visual Studio C++ is used! It can link via USB.2. Random images shown on my homepagehitechworld.orgThe redesign …

How can this be done? It is not so easy, as the LED matrix does not understand UNICODE.I have digitized japanese katakana font from a character LCD, about 5120 individual bits. This exists as binary data inside the microcontroller.I want t…

Cut it out Tyson posted by (C)takao21203Actually I have examined Fukushima prefecture (on the internet) in December 2010. It is a weird feeling. 1980s Japan took depature I think...altered color set posted by (C)takao21203But, how to follo…

By YURI KAGEYAMA | Associated Press – Fri, Aug 3, 2012TOKYO (AP) — Worn out and resigned to its dwindling status, Japan Inc. is said to be quietly shuffling off the world stage. But don't tell that to Kenji Hasegawa, who is ready to conque…

LED matrix showing temperature! I2C chip is used for temperature measure. Based on 16f59 microcontroller. 81% program FLASH is used. MPLABX/ XC8 were used for programming.8-bit microcontroller, 560 KHz. 50 LEDs, 3V supply.

1. TL494 SMPS (switching mode power supply). First tests have shown 12A capability. a large VGA cooler is used! However since I don't need it currently, the project sleeps.It makes funny noise!2. 1.8" color TFT This LCD has 384 kbit memory…

this is a prototype I have built for research purpose. Recently I have learned how to use MOSFET technology.1x VGA cooler is used together with IRF9540 p-channel MOSFET.20V/100A welding transformer is used as voltage source! With no load, …
