After much development and investigation Extron has developed some very unique and low cost basic Doppler speed radar measurements electronics. This has been used in various products including kickertube and a number of traffic speed advisory signs.
After a number of years of research and investigation into markets needs Extron has developed a low cost speed advisory sign. It has been developed with permanent installation in mind. The unit will display the speed of traffic up to 50m away with minimum reading of 20kph and maximum speed of 99kph. The unit has the ability to run from internal batteries with solar panel charging. The unit can have GSM connectivity to report the speed statistics on a regular basis.
The USB serial communications port is one of the most popular interface standards in the PC world today. Designing hardware/firmware to talk to the USB port can be challenging. Many years of experience and design work developing USB hardware has resulted in some very easy to use low cost solutions for this interface. Please call Mark for for information.
Using the Nordic series of RF link devices to provide a high quality audio link in the 2.4GHz range. Some very good audio quality results from this project.
Over a number of years an animal deterrent system designed to scar birds from food crops was developed, utilising a number of unique technologies a simple to use wires less audio system was developed that had very good results. Using moving audio around a crop filed the birds were confused and frightened off with no hard to the animals and the crops were protected.
Over the years Mark has been involved in the design of engine control systems, most notable a diesel engine control system providing starting and stopping control of backup system generators. Using a range of sensors and monitors the controller would look after the engine and start and stop it when required.
