Ya, it's glamorous. I have to beat the women off with a stick.
I'll put in the auto-dim sensor as well. It looks like the total cost is about $10 for materials only. We'll see what happens when I put it on an actual bike.

I doubt you could make one like this one yourself unless I changed the design to through hole and you got a PIC programmer, which is about $30. The SMD is a little tough to solder. As it is I have 8 PCB's here and if you want me to make up a few I'll give them out for $10 each with everything assembled. You would just need to add some wire length because the wire length to the sensors depends on your bike and where everything is mounted. I would actually like to see it on a motorcycle first before I gave these out though just to make sure I've worked out any bugs.
Someone mentioned hooking it up to the engine speed/road speed sensors. I can do that as well with this if you don't want to use the hall effect sensors, I would just need to update the firmware for it and try to figure out the technicalities of what to do when the clutch is in. You would need to hook up power/ground and tap into tachometer/road speed sensors. In that case it would only be $8. The hall effect sensors are $1 each.

I was thinking of using the same device to divide down the speedo signal to work with an Acewell dash. Instead I'm using a 7 bit ripple counter, since the Acewell has fine tuning to get the speedo calibrated.
For the gear indicator I've put together an arm (with a magnet mounted in it) that will mount behind the shift actuator on my bikes, this weekend I'll be mocking up mounts for the Hall sensors.

that looks great man, what is the size of it in relation to like a quarter.
I would like to add that to my bike.

how does this thing deal with misshifts? I don't really know anything about electronics, but it just looks like it counts when the shift lever goes up or down...

I'll take a picture with a quarter later. I'll order some better 7 segment LED as well. This one isn't that bright.
It uses the neutral indicator to reset itself. So whatever it's on when the neutral indicator goes on, it goes back to zero. If for some reason it gets out of sync, putting it in neutral will reset it.
It really is very simple. I've done much more complicated stuff than this. I'm just not certain how finicky it will be with the sensors.
Will swing by as the weather warms up. Seems like something to stimulate my mind

+1 seems interesting to me as well....

Hey, great job! You mind taking a picture of how you actually mounted the sensors? I assume similar to the OP with the magnet on the shifter?
Sorry guys, I've been way too lazy to actually put my gear indicator on an actual bike. I have to get someone over here to install it, but I just don't seem to have the time.
I completed up my display for the LC-1 wideband and made up a throttle position sensor display for TAFB and worked on some CAN stuff on my own bike. Some people PM'ed me and I'll try to book a time soon for a test install.

I had expressed interest in this earlier on, but I got a new job and settling-in. Don't have much riding time too. I put hardwood floor in the house too, another project that got me caught up. I'll have to make some time for this
Holy Moly! I know Vasil... we did grad school in electronics together at the good ol' U of T.
What a small world.

Oops... my bad, wrong Vassilis Papanikolaou (from the video, looks like this Vassilis actually lives in Greece)... I guess it's a big world, then, with so many Greeks having the same name (and being handy with electronics!).

A similar idea to the original. I made up an arm that goes onto the selector shaft behind the shifter. A 1/8" diameter magnet is inserted near the end of the arm.
The sensors are mounted to a piece of perf board shaped to fit between the water pump and the front sprocket cover. The perf board is supported by a couple of layers of fibreglass and protected by a layer of polyester resin.

That's awesome. Great work. This is why I'm being lazy about this, because I know mounting and tweaking the hall effect sensors on someone elses bike is going to be a pain. Just debugging TAFB's throttle position display took a while and it's pretty simple.
I made my display for the LC-1 wideband and I have a few extra if anyone wants one. It was interesting seeing everything going leaner after I lost the restricter on the exhaust.

All the connections between my bike and the controller are via a DB15 connector. It's probably quite straight forward to interface your controller with my bike. It would take some reprogramming for sure, but I bet your board is a lot smaller than mine.
Thanks for posting this link, I was thinking of getting one of these as I sometimes forget what gear I am in while turning 
, saved me $150. I just ordered the parts and will be building the exact same circuit linked in the first post with a couple of changes to the circuit including the light sensor that TheDirty mentioned.
