Is it simple to tether the nanonote to an android phone?

<wolfspraul>
good question, I'm wondering whether someone tried
<wolfspraul>
it would work if android could act in usb host mode and then forward/nat network traffic
<MistahDarcy>
That would be ideal and replace my needs for wifi functionality
<pcercuei>
if the "open hardware" side isn't the most important to you, you could try a GCW Zero device (once it ships)
<MistahDarcy>
Interesting. It is my goal to go for open hardware though.
<MistahDarcy>
Is sharism.cc the best place to pick a Nanonote up?

<wolfspraul>
yes, I think so
<MistahDarcy>
Thanks
<wolfspraul>
MistahDarcy: I am running that site and if you order there, it will ship with fedex from hk the next day
<wolfspraul>
if you are in the us, should be at your door 2-3 days later
<MistahDarcy>
Sweet.
<wolfspraul>
not what people are used to with amazon's great operation nowadays, but pretty good still I think :-)

2-3 days is crazy from HK
<wolfspraul>
well ok, I hope I did not overpromise now, urgh :-)
<wolfspraul>
sometimes there is an unexpected public holiday in HK, or the timezone adds another day, etc.
<wolfspraul>
but anyway, yes. sharism.cc it is
<wolfspraul>
if you order one - thanks a lot!
<MistahDarcy>
Definitely, it goes towards a great cause
<wolfspraul>
yes! thanks!
<MistahDarcy>
hopefully there will be more hardware revisions in the future
<wolfspraul>
I hope so too but they will be different :-) we need to apply all the many things we learned from the Ben and it's large brother the Milkymist One
<wolfspraul>
large and different brother
<wolfspraul>
but right now this is what we got, and it's not a bad thing to think about and tinker with, imho
<wolfspraul>
and use
<MistahDarcy>
I personally like the small form factor
<MistahDarcy>
I just submitted my order
<MistahDarcy>
Excited! :)

kristianpaul: i was thinking of the sample rate. didn't notice it had no separate I/Q. thought everybody had that these days :)
<wpwrak>
the form factor of the ben is indeed amazing. and i'd still love to do a successor. maybe an idea for a crowdfunding project ?
<MistahDarcy>
Crowdfunding would be great. Especially with goals set (for X amount of $, a better screen, etc)

MistahDarcy: that's messy and probably wouldn't work. you need one product, ideally without variants. otherwise you never get to useful quantities.
<wpwrak>
MistahDarcy: also, each option/variant you develop costs in terms of development effort and splits the user base
<MistahDarcy>
I didn't mean multiple models
<MistahDarcy>
For instance, if $10,000 was raised, a screen that had X resolution would be used
<wpwrak>
ah, i see
<MistahDarcy>
While if $20,000 was raised, the screen would be upgraded (for the entire thing)
<wpwrak>
there could be some things that can be done in such a way, yes
<wpwrak>
for the screen, you'd probably want something with about the same number of dpi as the current model, but with much smaller borders. i.e., the current resolution feels about right, but a bit more screen real estate would be welcome. of course, it depends on what you do - for a custom application, even what the ben has is often good enough.
<wolfspraul>
I see one big problem with that approach, based on my last 5 years of learning about hw :-)
<wolfspraul>
and that is that you don't "build" something with some budget X and then it's built and everybody is happy
<wpwrak>
wolfspraul: you mean the missing zero ? :)
<wolfspraul>
a hardware business needs focus on how fast inventory is turned around
<wpwrak>
well, you can sell more afterwards
<wolfspraul>
the number of days from when cash goes out to buy the first physical good, until the day cash comes in for selling the finished physical product
<wpwrak>
crowdfunding would be to get the thing rolling
<wolfspraul>
if that's not the focus, well. it will be a fun project but it will go nowhere from there.
<wolfspraul>
yes, it starts rolling an illusion :-)
<wolfspraul>
which is to 'spend' some amount of money to 'build' something
<wpwrak>
how is this different from a startup ?
<wolfspraul>
that is easy, I think we've done that in every imaginable way by now, no? :-)
<wpwrak>
and yes, of course, if you have things sit on the shelf for ages, that's not good. worse if they stay there forever.
<MistahDarcy>
Dreamcast. :D
<wpwrak>
split it in two and it makes sense: 1) R&D, 2) first production run. if you can charge just for 1), even better. else, you need to combine the two.
<MistahDarcy>
It's how I eventually ended up finding out about the Ben Nanonote. He's trying to live a 'year of open source' and he talks about the Open Moko
<MistahDarcy>
After searching and reading about the Open Moko, I started getting interested in the 'open hardware' concept, and now I'm here

hmm ... sounds nice but raising an entire hardware shop (three major products, all sorts of accessories) on just USD 72k and in less than 2 months ? http://www.indiegogo.com/pengpod
<wpwrak>
well, maybe they found an OEM and are just providing the software. similar to how the Ben was made.

hmm, does anyone know of a function that approximates averaging using a triangular filter/window, but without the need to store the whole sample set in the window ?
<wpwrak>
e.g., something similar to EWMA, but with dampening of new values, not just old ones.
<wpwrak>
the purpose is to find "off" given a series of samples of y(t) = off+amp*sin(t*w)+noise
<wpwrak>
amp and w are not exactly known
<wpwrak>
hmm, a slow enough EWMA may actually do the trick. not perfectly, but with reasonable accuracy
