Lightbulb Stromputer is alive

I started another thread months ago ("MK 1B") but it got long and very technical, so I decided to create a new one.

Basically I invented a digital solution that shows the current ambient temperature, current gear position and current battery level in an LCD display, gears showing also as LEDs. The solution is based on Arduino (AVR) microcontroller and can (and will be) expanded to have more advanced features - MPG (Miles Per Gallon) display is high on my list. If a GSA has it, so will the Wee! I also think of adding connectivity to smartphone via Bluetooth (e.g. show incoming SMS messages). The Arduino is a very capable and extensible platform.

I got some help from good Stromtroopers along the way (you know who you are.. ), had some bugs and fixed them, and did many experiments until everything got to work, but it really works now! The prototype is mounted on my bike and works great.



The core costs of the initial prototype were a bit high - about $110, not taking into account the mounting (RAM in my case) and other R&D costs (extra parts, wrong parts..). That been said, it is still cheaper than getting a 3rd Party Gear Position Indicator that does just that function.

The project is also open source: stromputer - Display enhancement for Suzuki V-Strom motorcycles (and others) based on Arduino - Google Project Hosting

I think the project is now ready to move to the next phase, which is more optimal and also much cheaper. I have clear ideas on how to make it cheaper - in particular consolidating all electronics into one box instead of two as it is today.

BTW: There is another project by Voltar, which is more of a DIY gear position indicator.

Cool.

Now I don't need to even think about a 2012.

Looks pretty good in person as well, I wouldn't mind one for my old campaigner. Does it work on all model years as well (mine is a pre-dual-plug k4, as you well know.)

Wrong video.


Pat- 2007 DL650A was ridden to all 48 contiguous states. 2012 DL650A is just getting started.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014+ DL1000s. Wee = 2004-2011 DL650s. Glee = 2012+ DL650s
See http://www.stromtrooper.com/general-...nicknames.html

I applaud your astonishing ingenuity (sparky things are a mystery to me). How small can you make it?

That's neat. Like Normin said, who needs 2012?

True!
I like the old looks anyway..

All V-Strom models have exactly the same gear position sensor mechanism. Therefore it will work on all V-Stroms.
Furthermore, I think it will work on any Japanese bike.

The device really needs three inputs:
1. Red Wire - Battery +
2. Black Wire - Battery - (GND)
3. Pink Wire - PosiTap to the motorcycle Gear Position Sensor (GPS) wire .

Time to install - Maybe 10 minutes.

Thanks!
The Stromputer can be made small by doing these things:
1. Using the Arduino Nano the dimensions drop to 0.73" x 1.70". I'm currently using a much larger Arduino Duemillanove (2.7'' x 2.1'').
2. The "Shield" I used for the prototype is both expensive and large. A small and cheap Through Hole PCB from Radioshack can be used instead.
3. Once I do 1 & 2, the entire "Brain" box is eliminated.
4. The current LCD is also large. If you go for a smaller LCD, a smaller box can be used.

so I do not have exact final dimensions, but think I will get rid of one box and reduce the size of the existing box.
