The CBR is going form 72 volts of Hawkers to 48 volts of Yellow
Tops. I have the new batteries, FINALLY, so now I just need to
redesign the subframe again.
I'm not sure what your design goals are for this bike, but this
sounds similar to one of the many configurations I have used on my
bike. I had similar sized batteries on my bike for a while and
managed about 10 mile range. I would expect you to get about the
same with the Optimas (unless they are the larger Group 31 version).
Also at 48V your top speed will be limited.
This will be my go to work bike. Top speed is 45mph about 4 miles
round trip in typical medium sized downtown stop and go traffic. In
all honesty, the Hawkers work really well but Tim the Tool Man sneaks
out...
Got some D34's.
Now, let me get your opinions on something. I am thinking very
seriously of releasing the schematics and source code to some sort
of open source license. There many different licenses and I don't
know which would be best. I envision a community of people adding
features and bug fixes to both the hardware and software of this
project. I'm thinking I might design a PCB and have a bunch made to
sell at a very reasonable cost - enough to cover expenses.
Thoughts? Comments?
I would not make many extra boards unless you have orders and
deposits from people. As cool as the whole thing is, it is likely
that when it comes to actually forking over money there will not be
very many people interested.
I learned that one from Lee Heart. We had a couple of email
conversations where we warned me of that. If and that's a big if, I
do build the boards I'll need cash in hand before I place the order.
To be honest I can't even remember exactly what the features of the
boards are, but I remember looking at them when you posted a link
and being impressed. Still if you use me for an example, I have
been riding my bike for over two years now knowing how nice it would
be to have an Emeter, but it wasn't until just recently that I
convinced myself to shell out the $360 to purchase an Emeter and
prescaler. As cool as your boards are, it is unlikely that I would
ever buy any because my bike is always very low on my budgeting
priority list.
I got an Emeter too but it's still in the box. With the hardware I've
purchased so far I can do what the Emeter does but cheaper and with a
better interface. Only, I don't 'know' it works because, while I have
all the parts, putting them together and actually getting them work
is another story all together. I'm right there with you Damon. My
bikes are pretty low on my list of life's priorities too but our
house rule is that if you're seriously working on a project you don't
have to do your chores that week. :)
As far as posting the schematics and software I doubt that there
will be much interest in collaboration. If you put it out there you
are sure to find a few folks who are thrilled that you have. Most
people will be looking to learn from your effort without putting in
much of their own.
Agreed. Agreed. Expected.
Good input. You pretty much confirmed what I was thinking. Thanks!
