Possibly with a potentiometer and bi-coloured LED's.

Thanks to Stuart

That's really easy to pull off. My mouse can do that.
If you literally want to know how it's made from scratch:
Someone would build a circuit that has a timer chip, some digital outputs, 2 LEDs and a small microcontroller. The tachometer gets connected to the counter, maybe you could get the signal from a spark plug. When it detects high revs it changes colour by switching the one LED off and the other one on. They could also vary the brightness of the light and mix them by using pulse width modulation (PWM). Or make them flash any colour of the rainbow, pulsating in waves the more you rev if you used red, green and yellow.
I wouldn't know where to buy one, but something like that is very easy to build (as long as you have a fair understanding of electronics and some low level programming skills).

cant be a potentiometer - cos thats just a variable resistor - common use for a potentiometer is a volume control - so maybe you thinking of some other electronic componentWiK1d wrote:Possibly with a potentiometer and bi-coloured LED's.

LEDMod.com ???
http://store.ledmod.com/index.php?main_ ... x&cPath=23
but these are custom built gauges.
and only for a few cars!
granted though, it cant be too difficult to make!

Re: How on earth did they do this???
You could do a manual joppie.
replace the original bulp with sharp Duel LED Blue & Red or something.
You get LED that has 3 legs 2 positive legs and one GND (Gives 3 colours) then connect the GND to you know where and 1 of the positive to the current positive on the original fitting of the old bulp (Make sure you drop the voltage some how) Then have a contact on the rev counter behind the plastics (This will depend from car to car to touch another contact on the 3rd leg of the
LED at the REV you want by adjusting it. And it will change the colour.
Sounds like a dodgy setup but if done right it will work.

Re: How on earth did they do this???
I'm tempted to try... although my car is still under motorplan... anyone wanna try and let us know the results?
Re: How on earth did they do this???
Seems like a fun project i have a velocity , Should be easy, but i have taken the speedo part out before on my previous golf to try and clean it and it ended up being a mess stuff wouldnt go back in like it was. Only Germans know how they assemble their funny setups.Vampyre_2099 wrote:I'm tempted to try... although my car is still under motorplan... anyone wanna try and let us know the results?
