Hello there …
I`m seeking a controller for my gearbox, and do not know where I
must find one or someone who can make one for me thats why im writing in here 
I have a proto type air shift gearbox on my dragster under
development, and I need a fairly simple control for it.
what I need it to be:
- Must have 2 buttons, 1 up switch button and 1 down switch button
- Must have 4 relay outputs (to control 4 x 12V air valves)
- And large digit 1 digit display that can display the gear im in (1 - 2 - 3 - 4
) example:
1st press on up button must show 1 and activate No 1 relay, 2nd pressure on
up button and it will show 2 and activate the No 2 relay ect, and when it reaches
four, it must go down again from 4-1 again by pressing the down button, it has to be that cycle to prevent the gearbox in engaging i two gear at same time…
(buttons to be built into the steering wheel and display, into the dashboard)
( the digit could be spared so its just the control )
I only have 12v available.
maybe someone knows where to find something similar or make me one …
thank you in advance …
with regards …
