Electronic design service is available, generally not for a one off, as it is not cost effective, because a lot of time is involved in the design work through to pcb populating.
timers with sense inputs, in the form of a switch or pir etc to trigger an output for a given length of time through a custom written assembly language program, using a micro-controller, boards are available.
These boards are ideal for coin operated timers, and are currently used in seaside telescopes across the coast which control a stepper motor, in this case the viewing time and control was made to suit the application from the customers specification.
The timing can be changed to suit the application, the outputs can turn something on or off, or can be used for a wide range of applications.
All boards and components used, are assembled and manufactured in our workshop, using high quality components.
pcb dimensions 600mm x 500mm
Latest design, this is the pcb schematic below, which i have just cadded out.
a pic micro-controller board with a variable input voltage, which is programmed for a watch alarm
this has various amplified transistor ouputs and trigger inputs configured for multi use, by changing the program code to the chip.
