Design Caller ID using DTMF decoder MT8870

il rassemble tous les ports, disques durs, ram, connecteurs, sockets…etc qu’on peut trouver dans nos ordinateurs…
Ainsi vous ne serez plus jamais pris au dépourvu devant un connecteur que vous n’avez jamais vu. A conserver accroché au mur pour tous les fanas de hardware, en guise de memento.

SeaTalk is a simple interface for networking Raymarine/Autohelm marine equipment so that all devices of a ship can exchange and share their data. SeaTalk is a proprietary solution of Autohelm and not compatible with NMEA or CAN. Unfortunately Raymarine keeps the technical details of SeaTalk secret. To assist users who want to develop hard- or software to connect their devices to the SeaTalk bus these pages uncover some of the mysteries. Part 3 adds hints how to interface SeaTalk with a PC.

This instructable will show you how I developed a simple yet full-featured digital sampling oscilloscope that I hope will enable you to get a successful start in this domain. The main goals in this development were:

Openembedded, your best-in class cross-compile environment. Openembedded allows developers to create a complete Linux Distribution for embedded systems.

The MicroClient JrSX represents the least expensive x86 compatible computer solution available. The MicroClient JrSX uses the revolutionary System on Chip, the Vortex86SX, that integrates a complete computer on a single CPU.

The final goal of the MICROTRANSAT challenge is to sail across the Atlantic ocean with a fully autonomous sailing boat. The boat are supposed to be small (less than 4m), fully autonomous and unmanned (no other energy than sun and wind) and cheap (it is supposed to be developed in an academic context, as a support for research and/or teaching)

This circuit takes standard 0-10V control voltage (for example from analogue light controlling desk) and outputs a standard 1-2 ms RC servo motors control pulse.

This document descibes the interface used by the PS/2 mouse, PS/2 keyboard, and AT keyboard.  I'll cover the physical and electrical interface, as well as the protocol.
