Digital gear position ideas?

[Guest]

Hey guys, I'm looking for a single digit display for gear position instead of the 6 lights.

Does anyone know what I could use for a circuit with 7 inputs to control what the 1 digit display will show from 1-N-2-3-4-5-6 ?

The GS1100EZ(82) and ED(83) have a digital 8 segment display for the gear indicator.

The pre 1980 550s had them too.

A single digit display? :-k

I thought they had the sequential numbers like all the rest.

Some of the GT 2 stroke bikes had that kind of display.

Yeah, I had a GT380 in 1982 that had a single digital display. The GT380 was a 3 cylinder 2 stroke.

The plastic used on the clocks then were prone to cracking due to sunlight.

A one through six digital window, not sure what you call it but the segments change to give the different numbers. There is no N, it has a separate neutral light.

In electronics parts catalogs they are called "7 segment" displays. The 7 segments being the 3 horizontal bars, the two vertical on the left and the two vertical on the right. Can get them in 1 digit, 2 digit, 3 digit and so on, maybe with decimal point dots inbetween the digits. Can get them in various colors (mostly red and blue), and various voltages (mostly 5vdc).

Problems using them for this application:
- the leads on them are for each segment. By that I mean this wire is for the top hrizontal bar, another wire is for center horizontal bar, another wire is for upper left vertical bar. ectera. They expect some other device to figure out what bars to light to make something that looks like whatever number.

- Can not make a "N" too well. Can make a "0" (all segments on except the center horizontal bar).

- the wires you have from your gear position swtich are "complete the ground" type connection. Say, for example when in 1st gear, the wire for 1st gear is connected to ground.

I guess I am better at describing the probelms, than I am with suggesting solutions.

There are these

They are 14 segment displays that could say N but 0 would work well with the 7 segment display

I read something about getting a single digit display driver that would activate the right segment depending on the input but haven't looked too deep into that yet

I worked out that with this display I could do it with a bunch of diodes.

Each output from the sensor would feed 2-6 diodes depending on the number and each one would go to the right segment to be lit up.

So for a 1 I would need two to light up one segment
For N I need 6 diodes
for 2 I need 4 or 5 diodes depending on what I make the 2 look like with square lines or diagonal lines in the middle
for 3 I need 5 diodes
for 4 I need 4 diodes
for 5 I need 5 diodes
for 6 I need 5 or 6 diodes

That would mean I needed at least 33 diodes to do the trick. There must be a simple circuit that does all this in one package.

This is a fancy option:

something simple maybe....

My 84 GS1150ES has a LCD digital gear indicator. Neutral is 0, its actually a pretty nice setup.

Never quite understood why anyone needs t add one of these... They look odd taped onto one of the clocks or wedged in a gap and all it says to me, is that who ever needed to add a gear indicator has no clue of their ride... Imo but I think they look terrible and aren't needed.

Looks like the ticket to me. Pretty straight forward.

Agreed, First gear is obvious, the others don't matter. If you try to upshift from 6th who cares? It is just an unnecessary doodad used to boost sales in 1977. I have one on a few bikes but I honestly don't ever look at it.

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 couldn?t 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

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.

Alternatively, go here:

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...
