I think i'll have to get one just because you use Rush for your background music.. :)
Being an ATL guy like me, you can get an early version even ;^)
Can you expand on this? I'm a user of the Disptach 1, and would love to learn about what your product offers vis-a-vis them so that I can consider your product!
I've moved on from the card system to a completely encapsulated system without fuses (it uses digital circuit breakers instead). I decided the cards were just not tough enough for autos. I think the biggest differentiation is that this is bluetooth controlled and 100A. I am not familiar with the Dispatch except that I know it's real and this is still in R&D mode. Which is to say that it is not yet real. It gets a little more real each day though. Keep your eyes peeled to this thread. I've been posting my progress with videos as I reach milestones.
All true if the "constant current supply" is not using PWM. The bucks use PWM ... if you are using that too to get your "constant current" then the efficiency should be similar.
Some systems for LEDs don't bother with a true constant current, they use the LED and light persistence to do the filtering on the PWM signal... leads to better efficiency.
A note on the horns...
On page 1 you said something like "One horn button - initial operation to the normal horn, after 1 second to the loud horn." Sorry but if someone wants the loud horn they want it now... not after any delay. In any emergency situation you want help NOW.
PS your definition .. well what happens if the resistance is not constant? EG a common light globe. Think about your Thévenin's and Norton's Theorems ! I stay away from definitions in most forums, they confuse rather than help?
There are some EMI regs that you may have to meet... FCC? Or some other gov agency.
I think I am more likely to find the horn I normally tap, so I'm willing to use it knowing that I'll have a LOUD horn on the way. That was not my idea, but it is a good one. It may not be for you, but when fit hits the shan I won't find the loud horn if I rarely use it. The delay is welcome in that exchange.
I'm pretty excited about this Crafty. This incorporated with DSM and running on a 7 inch tablet would be an awesome heads up display.
I was thinking the same thing.

interesting... long time flashlight/LED nut here ...
here's an ancient pic testing forward voltage of a 5watt Luxeon LED with a vf of 5.99v. which used to be king of the hill in output. but those days are long past.
Check out the bluetooth programmable circuit breaker function.

Me too. The last Garmin I plan on buying is laying somewhere in the Talladega NF.
Anybody want to buy a Blue Sea fuse block?
Will I be able to use this as an ignition switch or would anyone be able to turn it on with there phone?
While I plan to allow you to keep the radio on for up to 48 hours at a time I don't think it makes a lot of sense to keep the radio on all the time. Therefore, I'd not use this to turn on the bike. I think it would be a fine idea to use it to power the starter motor though. I expect security through obscurity to be pretty good with this device though. Until OEMs install these at the factory I expect the last thing a crook would do is pull out an iphone to try to hot wire your bike. Ultimately, I think most bikes are just put on trucks and dealt with in the privacy chop shops. YMMV
I wouldn't be too keen to have a Bluetooth ignition switch. RFID yes, but BT, no way. Believe me, BT has *SO MANY ISSUES* that I'd never trust it for anything crucial.
I wouldn't operate it via BT either. But, that is what the signal inputs are for. You would use a momentary button to trip the signal that energizes the starter motor. You could also use an RFID to trip the signal that energizes the fuel pump and use that as the "key". BT is mainly for programming and real time telemetry for those interested in that. BT is not going to be required for use of things that you need to interact with regularly. We are wearing gloves so digging out your phone to do stuff would make this product pretty annoying. Something I have no intention of it being.
There are 4 signal inputs that can identify two states each (ground and 12V but not at the same time). So that gives you somewhere between 4 and 8 signals depending on your creativity in designing your setup.
Very cool Crafty. I'm really liking what you have so far. By the way I'm just south of Atl, a gadget freak at heart with all kinds of electronics on my bike, and a software tester. Let me know if you need any help with testing too.
We still need to hook up for a ride one day. I did part of that Atl to Fl ds ride down to plains, GA last Sunday. Had a blast.
The final pre-production prototype is working great. Time to build a pile and see if people like them.

Dimensions are 1.5"x1.4"
Looking great, Josh!
What's the parasitic draw of the device when the input trigger is off (below 12 volts)? Does the current draw vary, over time, in its 'off state'?
