also provides temperature, Installed on my DL1000. Cost was about $20. Read about it and build your own if you wish: http://ijprojects.blogspot.com/2012/01/suzuki-v-strom-dl1000-gear-position.html
Nice job. I've built a similar one, no temp, but automatic brightness control. Based on arduino. Haven't permanently mount it yet though. Not a full info, but some write up and approximate schematic here: http://babayan.name/2010/11/gear-indicator/
Nice. Do you have any pics of the final build? Temperature is very easy to add with the sensor from my project. Is yours designed for a V-Strom?
Yes, it is for a strom - it uses the gear position sensor. I sourced the matching connectors to, so I didn't have to splice anything. I'll post the pictures once I get it installed.
Cool projects. I've done some noodling about with an Arduino, and it's pretty fun. I haven't done anything with the PICAXE - does it have a PWM output like the Arduino? I really like the auto dimming feature. I assume the signal voltage on the DL1000 is the same as the DL650?
The PIXACE does have PWM. I designing a meter clock with the 14M2 and it has four PWM outputs. I think all have at least one. I don't think the DL650 has a 6th gear so I would assume the voltages to be different, but the GPI wire to be in (or about) the same location. I just drove around a bit with a voltmeter connected to the bike to characterize the voltages for each gear. They are pretty stable. I like the PICAXE because it is very low cost and the minimun circuit off the dev board is only two resistors.
So could a dimmer be designed for this, when using a PICAXE? My left foot disagrees with your disbelief in a 6th gear on the Wee. Or it has 2 5 gears.
OKay, I thought the Wee was a 5 speed. Sorry about that. Looks like your left foot is smarter than all of me. As for the dimmer and the PICAXE... Yes. Without giving it much thought I think the easiest way would be to PCM the display. Like I said, I really haven't thought it through but I know the PICAXE could handle it. That said, the display is not blinding bright at night. If I really did need to dim it I would just go low tech and clip a piece of tinted film on it at night. Since I don't do much night driving it was not a concern for me.
Come on, where's the inventor spirit? You already have gone the non-minimalistic route by getting the GI, why stop now As far as added complexity, it was pretty much nothing - or, rather, the "flaw" of the LED that I used (common anode) turned into a virtue - I only had to PWM one pin instead of 7.
I was thinking about the display as I was riding today (200 miles of fantastic East Bay hills). What would it take to get a single LED to light up when it detects a certain voltage (within a small range). So, when you're in 6th, a green LED lights up. Is there any way to do that w/o programming a PicAxe, Arduino,m etc? Could it be done with just a resister? Related question: what's the voltage on a DL1000 for each gear? Thanks
It's not that hard. Do a google search on something like: vstrom voltage divider gear position sensor. I am away from my desktop for a few days or I would hit you with the link.
I'm selling the Gear Position Indicator that I designed/built. The starting price is a mild $15. See: http://www.ebay.com/itm/120957144473 Go nuts, Bid early, Bid often. Or, you can still build your own from: http://ijprojects.blogspot.com/2012/01/suzuki-v-strom-dl1000-gear-position.html
Thanks for the comment! It has been done before. I just decided to document the heck out of the build and open source mine.
In your ad, you mention that you made a new one and put it in the tach. Got photos? Seems like a cool idea.
It is very cool. I have not completed mine yet, but look at the 13 second video near the top of the build page to show the results from a DIY'er that built my project: http://ijprojects.blogspot.com/2012/01/suzuki-v-strom-dl1000-gear-position.html It looks very professional/factory!
