Any body build a Shift light? buy a shift light? Ideas for how to build one?

 

If you're going to build one yourself you need to scope the rpm signal to the gauges. It will be a square wave of some kind, just figure out what voltage it is. The you could hook a signal generator to your tach and watch how it reacts to different frequencies. Find the frequency that corresponds to the rpm you want to shift at and build a circuit that sends a voltage above that frequency. Use it to trigger a light and you're all set. Otherwise most stand-alone shift lights cost $80-$200.

 

Seeing as i don't have a scope, could i find good use for one in the future, or should i put the money towards a stand alone shift light? I'd love to take on a project like this cause it'd def be a challenge, but I could see a scope costing $80-$200 and if i never use it again, well, that'd be kinda silly.

 

looking around I've found this one http://www.ecliptech.com.au/main_win_sep06.html. looks pretty fancy, a bit more than i was expecting which was really just a single LED in a barrel (like this one http://www.harlan-engineering.com/st...hiftlight.html). Any thoughts? there is a pic with one installed on a 929

 

get an Acumen -> http://www.acumen-electronics.co.uk/...___Shift_light

 

thanks, but again, it seems a bit busy and distracting. I think i'm going to go with the harlan, which I plan to use as an idiot light: "HEY, you're getting to red line! shift dummy" :-)

 

If you want to make it yourself these are cheap:

All it does it put a voltage out, so you would need to source you're own LED array. In US dollars it is around $22, but who knows how much shipping from Australia is. That $50 light might be worth it since it's ready to go and looks good.
