Thinking of a new gadget...

Again, can't wait to see the finished product. Your knowledge and attention to detail are well documented in this thread. Honda would do well to have you on staff...

There are two new minor software features added:

(1) Ride timer, cosmetic: the colon between hours and minutes now flashes once per second, just as it would with a "normal" clock.

(2) Persistent ride timer: the timer will start from it's last value until reset. It bothered me that the timer was reset every time I stopped the engine - sometimes just wanted to take a photo from the roadside, or refuel, and have the timer keep going. Now it won't reset until the ignition is turned on then off within a second. (Note: the timer still will not run with the ignition turned off, but will start counting up from the last value saved). Reaching 9 hours and 59 minutes will reset the timer too.

Working on the housings now, will post photos later... Gold Oxide: no, it won't take that long :D
 
^^^ Cosry: (2) is a useful idea that can come handy. The reset method is convenient.

(1) is useful too as a fatigue checkpoint and appears to be common on many modern machines.

I guess it is time for a new update... Been working on the first batch and found a few glitches (and fell into a few traps too). Below are the details:

1. Assembled a set of five gadgets (electronics). Decided to add a serial number to them which is displayed during boot and also visible through the epoxy casting (the yellow label). This allows me to keep record of the exact calibration parameters of each unit.



2. Being the guy with belts AND suspenders, added the individual calibration data to the program memory too. This means that the program is individualized for each unit, and serves as an emergency backup should the EEPROM get zapped.

3. Found the 45-degree mount to be less good looking than I expected. This is mainly because of the curved backside, which is impossible to sand/paint nicely. Redesigned the stand, now has a smaller footprint and a rectangular backside.



4. This was a big ouchie: grabbed the wrong spray can one night and washed the completed units with an SMD flux cleaner instead of the resin flux cleaner. (Resin flux cleaner does not contain acetone, SMD flux cleaner does...) Next day found four of the five units having ugly "shadows" in the backlight. Took them apart (which was a royal PITA) and turned out that the acetone discolored the backlight diffusor. Now waiting for new display modules to be delivered... (Trying to learn from my own mistakes, but I'm not immune to my own stupidity :D)



5. Despite all the above, managed to put one unit together. This is the photo taken after casting in epoxy. Bazbro, do you recognize that serial? :D

 
I think this is an excellent addition, not so much for the CB1100 where it actually HAS a repeater, but for maybe older 'bikes where there is not a repeater or where the repeater is even less visible than the CB1100's.
Having a repeater up into the eye line is much more effective.
The big appeal of this device is that it is SO versatile, giving options for all kinds of 'bikes and all kinds of demands..
 
Hey Csory: I strongly recommend keeping the interface for the coolant temperature sensor. For me personally, I have no issue with the Honda instrument cluster indicators.

Alternatively if you still feel otherwise:

Make a temperature sensor programmable for either oil OR coolant. In this case you won't get both, but the rider can choose which configuration they want for their bike.

I feel feature creep has legs. Might be good to turnover Version 1.0 and get user feedback?

Ok, I'll take it as a "no" for now... Had a fleeting idea - tried to detect turn indicator activity via periodic drops in battery voltage. As long as the engine is off, it worked brilliantly - nice 100mV spikes at every blink. However, once fired up the engine the generator spewed so much white noise that I could not detect those drops anymore (at least not reliably). Even tried AC coupling + FFT to no avail :(

Will go ahead with the original version and maybe add turn signal indicator later...
 
Basically a spark gap transmitter.
