So process so far goes
Make board -> make software -> make new board -> Make casing -> bin everything and start again with 90% new software & hardware
If im to understand correctly?
Interesting stuff anyhow - have been most impressed with the 3D printer thread especially as i'd never seen anything like it before! ____________________ Please be aware that the above post may be full of complete nonsense.

Annoys me how they say a 3D printed car, its not even close, Its a 3D printed body covering a car chassis.
Still very impressive though, I imagine it would let them do some funky things with the air flow fairly easily. ____________________ Current Bikes:Honda 929RR Fireblade, Honda CD200 Benly (Project), Stomp Z2 140

Here's the thing... I've made a nice little voltage divider, which takes 14v dc and drops it to about 4v dc. I've worked out that (I think) the tacho signal that goes to the dash is ac. I've got a salvaged wiggly to straight electric making doodad which takes said wiggly, and spits out straight electricity. I hooked it all up, with a little test led and... nothing.
The led gets (after rectalification and voltage division) about 1-2v which isn't enough to light it. This is where it gets annoying...
The multimeter shows some voltage on ac test mode, on the led + and -. This either means the rectificatoriser is bent, OR there's a nice dc pulse there. But the pulse is of very low voltage.
the actual leads straight from the dash show the following...
dmm in ac mode, 14v~
dmm in dc mode, 6vdc
Now.. if it's an ac pulse (say about 50hz or so) that's just ac, but low voltage (compared to house ac.)
If it's a dc pulse, my brain has just turned to mush.
Surely the tacho output, going by the evidence is a 14v~ pulse, and after rectification I've got a <14vdc pulse right? Assuming you lose some voltage through straightening.. I'm going to try reworking my voltage divider and see what happens to the LED. Brave test pilot. Arduino salutes you! ____________________ Current: VFR800 2008 13.7k and rising rapidly!

Just thought I'd add, in case you weren't aware of this..
The circuit that's connected to pin D2 on the arduino is not your average switch type circuit. You'll notice the lack of a resistor there. There's an interesting article somewhere I found which says you *can* wire a pin to ground via a switch *if* you enable the internal pullup resistor. Otherwise you'd normally have it wired differently:
Standard button wiring
https://arduino.cc/en/tutorial/button
With the circuit I've used, you need to put the following in your code:
Code: |
pinMode(2, INPUT); // This line is standard, sets our pin 2 as an input pin
digitalWrite(2, HIGH); // This line enables the internal 20k pullup resistor
|
Just so you know
Also so you don't sue me when my circuit breaks your 'duino ____________________ Current: VFR800 2008 13.7k and rising rapidly!

Don't mean to pester you here, but...
Are we there yet?

Just kidding. Are you planning on open sourcing everything still? If you are, and you have a chance at some point, I'd quite like to see an overview type checklist thingy with your progress and planned features/jobs to do. I've made some progress, and I'll be making another video to upload soon(tm) showing how far I've got. Also found some very useful things regarding tacho and speedo signals. I've already got a working tacho circuit that's pretty simple to implement and interface with the arduino, that eliminates the issues of voltage conversion and whatnot.
In fact, thinking about it, I may just update my website and stick an arduino section in there, with links to code and source inspiration and such. Like a bikeduino page.
