Hey guys! (LubeyChain)

[LubeyChain]

Started doing this sort of thing ages ago then gone off it a bit. Used some tiny transceivers and simple ATTiny chip to send data from bike to helmet which worked really well with thumbnail sized pcb antennas. You can have all my work to date on that if you want it...

Cool! How did you get the signal from the indicators ? Right now we are thinking of tapping into the wire and get a current signal then transmit via a RF transmitter. The prototype works with arduino.

Some info on it in this thread http://www.kiwibiker.co.nz/forums/sh...=indicator+hud

I tapped into a number of things, indicators, high beam, oil light, rpm, neutral. The transceivers I used were digital comms over SPI (iirc) so you can pair the bike/helmet units to each other and send a decent amount of data. Like if you're doing GPS speed, augment it with rpm from the bike to give a speed that updates a lot quicker.

Nice,
How did you tap into the wires? Did you use a voltage reg?

Right now we have everything working. We have the speed updating every second, and the indicators working with RF just need to tap into the bike.

You seem to know heaps about motorbike circuitry (I don't hah). You might be the man to help me get this running.

If it all goes well, I'll be looking into marketing the HUD and getting investments.

price wise my HUD prototype cost me around $140. And thats with the branded arduino (I can build one myself if for mass producing).

Next week I'll post a thread with a video and photos so you guys can check it out.

Edit: also im trying not to tap into heaps of stuff on the bike as it's frowned upon.

Nah just a bunch of passives, was kinda tricky cos signals can change all over the show, active high/low, present/not when indicating. I think I just split the signla into two inputs, one if it were high, one if low, then used software to figure if it were toggling.

I reckon tapping into wires is no issue, you'll probably sell the intitial stuff to modders anyway. For the price of an extra dangly bit of wire you can add a lot more functionality to it, firmware being free of course. And the more info you have access to, the more likely you are to be able to hit the customer's value proposition.
