I wrote a small C program for this graphics card. It is a CGA model which was used in early 1980s!After a while it really works.A lot of effort is required to set a single pixel. 320x200 in 4 colors...Borland C++ is used but this program i…

C program which I wrote. It can set pixels, draw a circle, and draw a box. All very primitive- technology from 30 years ago.It is old graphics card and MSDOS (FreeDOS) which runs in a hard drive partition. C compiler is not free but it is …

Given the fact most operating system files are almost never used, essentially these files are slack. OK they have to be there, belonging to an installation, and the software eventually is used in very few cases.Actually this can be 10,000s…

Compressing file system - LINUXWhen I installed MPLABX + all the C compilers, about 98% of the hard drive partition was used. There are about 20000 files or more!1. I created a new partition, and moved 4.1 Gigabytes installation there.2. I…

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.…

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…
