I have one of the BAC500+ units, nice flat form factor is perfect for my flat BikeE frame, if it will work for the BMC on that bike. Another delayed project. I retired a year ago, have been able to get a few projects moved along, quite a few more to go.amberwolf wrote:Back when my CA v3 still worked, I had planned to carry an old laptop in my CrazyBike2's metal side cargo pod, padded with chilled (but not frozen) gelpacks to both keep ti from vibration/bumps and absorb it's heat, but I didn't get that far before various events got in the way.
I was also going to test out an old serial-port-type PDA and see if that would also work, but I hadn't found a datalogging app at the time.
Nowadays I would probably see about using an old android tablet or phone for it, if serial input devices for USB on PC's could be adapted to them, and datalogging apps exist. At least no risk to harddisk crash from impact or vibration in those. (though one can also use a USB stick to run a laptop from, and remove it's harddisk--might end up more practical as I have a few very old laptops that might work that way).
For the trike's wheels, I actually use the separate throttles to steer it in turns a fair bit, but it would be nice to just be able to use a single throttle to control both wheels under most cruising, and override it only in sharp turns.
Thanks to Justin's generosity some time back, I've got one of the original 500w ASI controllers (in the silver angular metal package), from Justin's bike on the Maker Faire trip, that I have experimented with a bit but so far haven't gotten it actually running any motors (lack of time mostly). I intend to try it eventually (someday) just to see how it works on the trike vs the regular controllers.
But a pair of PRs or the bigger BACs is well out of any budget for the foreseeable future. Still dreaming on that one, along with a lot of other things.
This 2WD is one of these interrupted projects, started planning a long time ago, bought the BMC over a year ago, just getting it going now. But it is much nicer with PhaseRunners than dual Xie Chen controllers, I don't know where I'd fit two of those, these PhaseRunners are so much smaller and easier to pack in.
I'll try the GoPro to start with, it would be nice to have digital recording but handling dual serial streams would be a project itself so I won't get that complicated if I don't need to. Perhaps I'll want to do that, but I'd really just like to get the controllers configured. Later I would like to build an Arduino based display that would look at both PhaseRunners, sort of a dual-CA in one, and if I'm going to do recording that would be the place to do it, then one datastream will be available with both sets of info.
There are inexpensive little boards from Sparkfun and perhaps Adafruit that will record serial streams on to SD cards, no need to carry a laptop or buy a more costly box. Lots of ways to do it.
