Necessity is the mother of invention, it is true -- but its father is creativity, and knowledge is the midwife. -- Jonathan Schattke

Crash programs fail because they are based on the theory that, with nine women pregnant, you can get a baby a month. -- Wernher von Braun

• We have 32 years of successful electronics design experience
• Our work is inventive, creative, and up-to-date
  We have a structured step-thru technique for designing boards
  • We have templates for each step - for speed accuracy
  • The documentation is done at the same time as the design work - therefore the documentation is good and thorough

AirBorn Electronics specialties are microprocessor based electronics, serial communications and top class real time software.
• For applications requiring small microcontrollers - AirBorn Electronics uses 8051 family microprocessors (the most prolific on our planet). These range in size from the tiny Atmel AT89C2051, a 20 pin 2 kilobyte FLASH memory micro, (for which we also make a programmer), to the Dallas 80C320 family, with performance that starts to reach into the 16 bit micro arena.
• Serial communications - AirBorn Electronics projects regularly involve RS232, RS422 and RS485 interfacing, both to PC's, modems, and as stand-alone communications between microcontrollers. We have experience with the mechanics of serial communications - implementing protocols, error checking, addressing, buffering.
• Real time software - AirBorn Electronics real time software has been used to make robots move, control building plant, count coins & ballots, open doors... software is the heart of today's electronics, and we write good software.

One special line of design work we do is Serial Data Conversion units - manufacturing an interface to existing equipment or protocol. Sometimes the requirement is for Serial to Serial conversion (the unit pictured does this function), but more often one side is serial, and the other side is something special - e.g. a set of relays, a DTMF telephone dialling interface, or totalisator meters.

The Units pictured are one of a line of standard hardware products we make - they are protocol converters. This particular D25-D25 converter fits in a standard inline case and supervises a modem.

Custom units to manage protocol conversion are available to order. Also available Serial to parallel converter - program, circuit and assembler, and RS232 To RS485 converter.
