The electronic dashboard was designed in the days when only very expensive cars were equipped with such things. These plans enabled any boy racer with a Ford Cortina to have an instrument panel that looked like it came out of NASA Space Control. It is pretty low tech., by modern day standards. It does not contain microcomputers and simply converts electrical signals from the car’s sensors into LED displays. The instruments include Fuel gauge, Temperature gauge, voltmeter, oil pressure gauge, rev. counter and speedo. To build an entire dash works out quite expensive, but the individual circuits could be useful to someone who wants to add a touch of flashiness to their dash.
25 pages. First produced 1985
that I would make if I were to do it today.
I don’t think that the 10 dot LED
display is made any more, but it basically consisted of an LM3914
chip and 10 LEDs on a small circuit board. That means that if you use an LM3914
and your own separate LEDs you can come up with the same thing. Plus you can
alter the colours of the LEDs to give a “Safe” and “Danger” warning. The
circuit and info for the LM3914 can be found at:
The speedo sensor (That fits onto the
speedo cable) can be obtained from:
It is on the page as the “Brantz Speedometer Sensor”. You will need to check the circuit that comes with it in case different voltages are required to drive it to those mentioned in the plans. (Maplin, who supplied the original ones, no longer stock them.)
