Fantastic work - will u share the code and the schematic too?

The current code is posted above. I will post the final version as well. I will also leave an ISP header in the device, for reprogramming.

The schematic is based on this one: http://ecomodder.com/forum/showthread.php/open-source-pcb-design-2641.html#post32427

The only difference Is that I added a 6 pin ISP plug and the resistor for the speed sensor is 10k ohm instead of 100k.

Here's a video of me going through the displays, as well as the menus.

If the video doesn't work, check back in a few hours. Youtube is processing it.

Fantastic! This work is mind-boggling to me. You are a genius! Much thanks. :2thumbup:

Well, Good news:

I am pretty much done with the design of all of the device. I am about ready to pull the trigger on most of the components, as well as the PCB's and I believe I have found a suitable, waterproof (from the factory) enclosure, that will fit in my budgeting for the project and still look nice.

Once those start to arrive, I will be able to start assembling them, pending my time availability (as well as my motorcycle trip, jun 15-28th.)

In the next few days I will post up the final details in the "Shopping Cart" section here as well as the "Vendors" section on ADVrider.

I am planning to charge $125 + Shipping for an assembled, waterproof, working device, which includes a wiring pigtail, as well as connectors for the fuel injectors, so as not to puncture the wire on the fuel injection harness. Clear, photographic instructions will be included.

I went out to the garage to have a close look at my K100RS with an eye toward considering mounting options. Did you ever post the dimensions of the unit? :hmm:

I believe it will be about 3.9 x 2.0 x 0.8 inches.

I am planning to mount mine with a suction cup on the gas tank.

If you are taking Pre-Production orders I'm good for one, just let me know where and how to send the $$.

i would like to have a bar end mount so i can see the dislay in my mirror...

I'm definitely still interested. I also need to know the form factor (dimensions, etc).

I need one with a head-up display in my Oakleys.

wmax351 · « **Reply #88 on:** June 04, 2012, 09:01:10 PM »

How about retinal projection Duck?

Form factor is a box, about 4 inches x 2 inches x 1 inch. Will do a computer mockup for better visualization soon.

Here is the box which I am using: http://www.hammondmfg.com/pdf/1591A.pdf

Bottom will be drill-able for mounting, or glue/tape-able.

Decided to add a voltmeter to the device as well. For 30 cents (more like 15 in larger quantities), seemed like a good idea.

Defintely on for one of these but going on holiday for a week so if you post in the shopping cart before then I won't be answering it for a while.

Just to check that these will definitely do UK Gallons ?

They can. You just have to change the values (Tank size and Fuel injector flow) to values in Uk gallons, rather than US gallons.

Just ordered 100 of the circuit boards from china. Will be here in 8 days. Unfortunately, that is the day I am leaving for my road trip. I will work on getting some of these done after that.

wmax351 · « **Reply #93 on:** June 11, 2012, 03:36:57 PM »

PCB's are in the mail. Delivery date: 6/13.

wmax351 · « **Reply #94 on:** June 14, 2012, 02:09:24 AM »

Just got the PCB's in today. They look good. Ordered the rest of the parts. Will start to assemble them when the parts get in. When I get the boards assembled, I will start finalizing the enclosures.

Meanwhile, I have my prototype boxed up, and have it running on the bike. It is working great.

wmax351 · « **Reply #95 on:** June 15, 2012, 08:52:13 PM »

Well, the prototype is perfoming great. I'm homing in on the time it takes the injector to open. They are quicker than the 500 uS default value. think its about 300 uS. Will see as it gets calibrated, should be constant across k bikes.

Currently, it is at about - 5% on the fuel usage, but spot on for distance. Should be getting more accurate as i lock down the values.

wmax351 · « **Reply #96 on:** June 29, 2012, 07:50:15 PM »

Good news on the production front: all 25 boards of the initial batch are assembled.

I need to do quality control on them, and check one of the capacitors: one was inadvertently switched on one of the boards, so i need to go in with a magnifying glass, and check them all.

Once that is completed, I will add the displays, as well as the wires for the switches and input. At that point the enclosure will have been finalized, and i will be ready to order and manufacture the enclosures. I have found some good switches, which were causing me some difficulty to find for a reasonable price. The ones i settled on are nice, have a good feel, and are waterproof. Cost about 3 bucks a pop, though. Still cheaper than most other waterproof switches.

Getting close to sending them out now. Will be ready about a week and a half after i get back from Ghana, which will be 9 days from now.

We have friends just south of Johannesburg, Peet & Carole, if you happen to get down that way.

Enclosure: I don't have a link but somebody over on ADV found a site where you can CAD your design online and they make it for you.
