Dashboard Suggestions

[Stevo]

Hello Everyone,
I wanted to start a specific thread on dashboard design that may help other builders in the future. When Lookie-Lous come up to check out your conversion in a public parking lot, one of the first places they spy is your dashboard. We should make them functional, but they should be impressive also!
In 2018 I am upgrading my electric dirtbike that I built with a ME1003/AXE7245 combo to a
a ME1616/Sevcon gen4sz6 combo.


I wanted to start this thread on dashboard design also because this is where I need the most help. This will be such a huge and expensive upgrade, I want the dashboard to be as advanced as I can make it, within my abilities.
Right now, the dash consists of a Cycle Analyst, a key switch, an amber led turn indicator, and an aux fan switch.
Simple and basic, gets the job done.

I want to redo the entire dash assembly. I will probably keep the CycleAnalyst, but I would like to ditch the key switch and incorporate a small waterproof rugged tablet like this:https://www.walmart.com/ip/WinBridge...&wl13=&veh=sem
My thought was that the tablet could be the secure interface with the SevCon controller, as well as gps and/or other basic dash info like speedometer/odometer (although CycleAnalyst already does that). I hope somebody here on this forum can help me with ideas, experience, and how to's to get this configured and functional. Hopefully, this thread will become valuable to other forum members.
Thank you in advance!

Maybe the Clearview Display from Sevcon?

or look into OVMS and this Sevcon implementation:

and

If you know the Canopen protocol, the Sevcon supports it, and you could code a microcontroller/CAN tranciever to "convert" those over to OBD-II parameters that could be read from something like Torque for android.

I found this thread about an RFID switch https://endless-sphere.com/forums/vi...FID+key+switch

It really isn't much different than having a key switch, and just one more electronic component to break and leave you stranded on the side of the road, IMHO. I may decide to keep a key switch just for theft deterent, even though it could be easily bypassed by a thief with half a brain.

I put an RFID key on my ICE bike using a cheap ebay rfid unit, and it has been working great for about 3 years. No keys, no problems. I put the antenna under the seat by my right pocket. If I have the fob in the inside corner of my pants pocket, I can just climb on, flip the switch and start it up. Slick! I have 2 shrink wrapped wires under the seat with bullet connectors as a bypass, just in case. If you don't know what they are for, you would never guess its the hotwire kit. Pull off the shrink, plug them in, and never get stranded.
The one catch is that you have to have a bit of battery, no push starting without at least a tiny bit of juice. Shouldn't be a problem on an electric though!

Your pictures are not shown for me, but i thinking about same thing.

But Android tablet for 399$ is a lot to pay. Sony Tablet Z IP55 should work for you, but it is quite large.

There is two different guys on endless-sphere which builded Android apps for cycle analyst.

One builded Ebike analyser - it communicates with cycle analyst by BT.

Other user builded more graphical one, but it communicates through Wifi and Esp2866, which not very common.

For my latest build, I builded my dashboard myself with Arduino Mega, USB host shield and 3,2" TFTLCD.

Reason was my original Manzanita Micro RBD display not show all information i wanted.

My display shows voltage/current and so on and bargraph for all cells inkluding min max. When it powered off it is just black.

The problem with tablet is that you need to find way to turn it off and too start it up as soon you power your bike. If it continue to ne on people will se that you have a tablet installed and it may be stealed.

Here is a possible solution to using my cell phone as a key: http://www.tinyosshop.com/index.php?...product_id=362
It looks like a good starting point. I'm still researching this whole thing out.

If you want to go total cool, look at this: http://ai-hmi.com/evic_products/



These guys were really responsive when I queried them. (https://evmc2.wordpress.com/2014/12/...perbike-check/)

Do they support Sevcon?

From what I saw, only Curtis at the moment, but that could have changed.

I just sent them an inquiry. I told them Ted Dillard sent me

Ted, that article is 3 years old, almost to the day... Can you update us with any new developments?
I ask because I want my next build to be a streetbike. I'm leaning towards a 2003-5 ish Honda VFR with saddlebag side cases. I figure you can fit alot of Li in those side cases! And they are easily removable. Like the BMW panniers.
