Cryogenics?
Like Wendel, I get a kick out of playing with bits of old junk and trying to make them work. Anyone else on here have the same mental ailment???
Good choice, going back to the eBay gear change indicator you could use two of them, have the first one set to the lower rpm and light the light and then use the second one set to the higher rpm to trigger a relay to turn the light of the first one off.Arduino kit and "Arduino for Dummies" book on order.
There's an echo in here!
I gave up on trying to form louvres on the bonnet and just made a few bulges and holes instead.
Yours A7 is looking good Rob. I am afraid to say that no progress has been made on my A7 as I am up to my eyeballs building my barn which is going to become my new workshop.I even found a revcounter that used LEDs instead of a needle, but that would be cheating. Splice a relay across one of the bulbs in the right region...anyway, The Arduino will give some flexibility to try other warning lights, once I've learnt how to programme it. All part of learning new skills. The A7 has no water temp gauge, runs 10psi cold and 1psi hot so maybe there is scope to add a couple of other sensors in there without making the dashboard look like the deck of the USS Enterprise. There is even a vibration sensor kit for the Arduino. Wonder if that would be worth trying (about £10)?
Wendel. Any developments on the A7 front? I gave up on trying to form louvres on the bonnet and just made a few bulges and holes instead.

I'm going to go the other way and suggest having a look at sticking a harmonic damper on the crank?
What he said, although a small relay might be less troublesome than a transistor if the OP isn't into electrickery. The raspberry/arduino stuff seems a bit OTT unless you're adding other functionality.Two shift lights, take them apart and use a logic gate to select the lamp on signal. So, one set to 2200, one set to 2400 and perhaps just use a transistor to switch the 2200 lamp off when the 2400 goes high.
