Arduino Tachometer - How to interface w/ ignitor?

[Guest]

I'll take a picture tonight. It's exactly like this though - http://www.youtube.com/watch?v=9tiH5DL0Xdc. He just has the newer DSO Nano. The ground from the DSO is connected to the Arduino ground, then the signal generator output is hooked up to one of the input pins that is set as an interrupt. The output of the DSO when running on battery is 3.7 v, so it's below the 5v of the Arduino.

I hope to write a program just like his, where min RPM and max RPM can be set.

Once I get the program working, I can see what is needed to get it to work on the bike. Then I have to start thinking about the housing, which is a whole other hurdle.

Saw this today and thought of this thread:

Apparently the stepper motors they use in car dashes are quite cheap to acquire. I'm probably going to need a new clocks and wasn't looking forward to buying them, so maybe I'll build new ones instead! (My speedo squeals like a stuck pig and the cable connector on the tach is broken.)

It's really amazing what you can do with these Arduinos.

Here are some pictures I snapped of my setup so far...

Now I'm considering utilizing an Acewell mechanical to electrical speed sensor cable to include a speedometer on this. I'm not sure if they have one that fits the GS, or how it actually works (hall sensor? seems as though there is only one wire coming from the sensor). But if I do that, I really should use an OLED display to make it more robust and allow for an odometer and such. And if I do that, I should really create my own circuit board to mount all of these components in a specific housing.

Maybe I should just hook it up to my bike to see if it works first

Yay feature creep

If you do end up going down that route, BatchPCB.com has a really great (cheap) PCB manufacturing service if you don't want to deal with etching yourself.

I wish I could get home to work on my bike! Though being stuck at work playing with 3d printers isn't horrible.

<---- Jealous!

What kind of 3D printers, if I may ask? The question of custom gauge housings has been mentioned. I have an project dragging on involving making a mount for my volt meter on my printer (roughly in the category of RepRap).

We're currently working with the Replicator 2 from Makerbot. We're just getting started working with it, but if you have CAD files (STL specifically) I would be happy to try out a test print.

My co-worker and I have long-term plans to build a full dash for our bikes (he has an 82 Honda Nighthawk) as we're both planning on doing builds. They'll probably be a long time coming as we're swamped at work, but it's a fun prospect anyways. My co-worker has already made his turn signal mounts and they came out really well.

It would be a bit of a dream of mine to put together the electronics from this thread and 3d printed pieces to build a full dash that could be hooked up to basically any bike.

I've wanted to build a RapRap for a long time now, but having access to the Makerbot at work makes it kind of pointless. I'd love to see pictures of your setup.
