Sun Type 5 keyboard on the PC - Presented here is a simple micro-controller
device that will talk to the Sun keyboard and the PC's keyboard interface and convert
between the two. You can now throw away those nasty cheap PC keyboards and use a real
keyboard on your PC. While the original schematics seem to indicate that it converts
the Sun mouse to a serial PC mouse, it does not work for me....(electronic circuit

Supervisory circuit monitors-modem connection - 04/09/98 EDN-Design Ideas
In telemetry or security applications in which a modem connection automatically
establishes itself between two systems, a failure in one of the systems can interrupt
the data exchange while the connection remains established until someone physically
breaks the line or restarts the failed system. This situation....several
circuits included, scroll the find this one.... [Design Idea by J Bas�lio Sim�es and

S-Video to Composite Video Adapter - This simple adapter can be used to
convert Y/C video (S-video) to a composite video. This adapter is useful in
cases where your video output device has only S-video output but your signal source
accepts only composite video input. This circuit works with both PAL and NTSC
video standards. (added 4/05) |

Synchronizing Controller detects baud rate - 03/02/98 EDN-Design Ideas
A simple and inexpensive implementation using an eight-pin 12C508 controller
(Microchip Technology, Chandler, AZ] provides both bit-rate detection and a
synchronous, appended-clock output from an asynchronous input-data stream (Figure
1a].…File contains many circuits, please scroll to find this one.... [Design Idea by
