Digital gear position ideas?

[POULSEN]

I have searched everywhere for at 7-segment display driven by 6 switch inputs, as used in the early GS models - with no success .

You could use a "raw" 7-segment display with a lot of discrete diodes and resistors as shown here: http://www.poulzen.dk/pictures/7segment.gif
but I really couldnīt recommend.

As several suggest, it is not the most useful instrument - the actual gear is not that important as long as the revs is in a meaningful area.

The original 7-segment display suitable for the switched inputs is obsolete as new sparepart, and rarely found as used (in working condition). I changed to a later console with separate LEDs, not to be annoyed by the 7-segment showing i was in gear: E, H or similar

That's actually what I'm doing right now. I'm just collecting diodes :P

I know its not necessary at all. Its just something I like to mess around with.

Since I started looking into this I'm thinking about using something like an Arduino to control a display that would have useful things to display.

Gear position would be an easy project I would think.

I could then add things like:
Voltage
Map pressure
EGT
RPM
Speed
Oil temp
Oil pressure

And I could use it to control all the running lights and ignition.

i could be waaaaaayyyyyyyy off here, but is this the sort of thing you are looking for?

You got it, That exactly what I was originally looking for.

Found this guy's site from someone else quite a long time ago and thought this was pretty cool.

He also has a schematic for the stock GS450 ignitor on there by the looks...

[Mekanix]

Lol that schematic is exactly what I had in my head.

way too many diodes in my opinion.
You could do with less than half - and save a dollar

I used one of these on an 83 GS750ES. It has neutral which you can use or not. You have to build your own enclosure for it.
Very easy to connect up. I had to go through & test each connection to figure out which color wire related to which number etc.

how does that wire up then? it says you need an electronic tacho and speedo so where does it get its input to determine what gear it is in???

[Gibbelstein]

I read this a while back. This guy cooked up a version that can be added to any bike. It 'counts' up and down shifts. Thought it was an interesting project:

It uses the stock Suzuki module at the shifter. You basically just wire this in directly in place of the stock lights (the 750ES had 5 little bulbs in the gauge cluster). It's not intelligent, put 12v across different wires to get it to display different numbers. Really simple.

ahhhhhhh, i see. not something you could easily fit to a stock GS then...
(not that i want one...daft idea if you ask me )

[salty_monk]

There are ones like that with the hall sensor available on EBay too. I bet it's cheaper to make your own though.

The only thing I've read is they can be confused by a miss-shift or a false neutral etc. No big deal though it would still be useful.

Not sure... if you could replace the old module on the 78's etc with a newer one from a model that has a gear indicator stock (my 80 1000G had one for example) then it would work.

That's awesome but what about 6 ?

Maybe add another line that activates 5 and another diode to the last segment to make a 6.
