Following up on this, is there anyone else who would like their name
added to the list of collaborators at the end? Or like their name
removed? I know Vik and Scott were interested but didn't want to take
the liberty of adding people who hadn't specifically said they wanted
in.
And this is one of those situations where I *know* I've overlooked a
name, and I'll feel like a tool when it's pointed out to me.
Cheers :-)

Just wanted to wish you luck. My wonderful news is that I am having
another baby (well, we, not just me) - and since it is due January I
think I better not offer any help :-)
Good luck

Hey, congratulations to both you and Amanda! That's excellent, I'm
really pleased for you.
We'll miss you at LCA but I'm sure you'll be having a much more
interesting time than us.
Cheers :-)

based, so I can talk a little about our experiences and hackery with
it. Also our Sanguino variant and stepper drivers, which Arduino
affectionados seem to find useful.

That would be great. I was hoping the RepRap would get a showing of some
kind, even if it does end up featured in the main conf as well.
By the way, I should clarify that the names at the bottom of the
proposal aren't commiting people to doing presentations: the idea was
just to show the people who have been helping drive and formulate the
structure of the miniconf. Co-organisers, almost. I'm expecting to do
the grunt work of organising speakers, arranging the schedule, chasing
sources of parts, etc, but having those names on the proposal will
hopefully indicate the level of support that the miniconf has / will
receive.
Cheers :-)

cabal). I'm sure the local Makerspace would be happy to host some
extra-curricular activities too, particularly if beer is involved :)
BTW Where are you getting the shield PCBs made up? I'd like to get
some simple TIP121 transistor driver boards made too for driving
relays, motors, fans and whatnot.
We could go stripboard too!
Vik :v)

Probably pcbcart.com. I submitted an order to them yesterday for a batch
of 100 prototyping shields. I've never used them personally but I chose
them on the basis that a good friend of mine has had tens of thousands
of boards fabbed by them over the years and says they've always done a
brilliant job at a bargain price on a short lead time. I can't argue
with that!

I've been intending to do a general-purpose output board, and Scott's
pointer to this got me back on the subject:
http://effluviaofascatteredmind.blogspot.com/2009/02/my-first-arduino-shield-arrived.html
I was thinking of maybe a board with something like a single M5451 or
equivalent driving a bunch of transistors to get lots of outputs while
using minimal I/O lines. That's the sort of thing I'd be happy to get
fabbed in quantity and make available for some nominal price because I
think it would be a very useful board. I could certainly use a few of
them.

driver in the Arduino library so driving the little sucker shouldn't
be too hard. Plus you get input and output. Not just lots of IO on 2
pins, but you can stack them to add in even more!
Like? I know someone who would make some proto boards...

That would be a nicer way to do it. I'd also considered something simple
like a couple of 4094s, but having bidirectional comms would be sweet.
This sounds like a very worthwhile project. Time to order some parts and
start prototyping! This is probably drifting a bit off-topic for this
group though so maybe we should chat about it directly.
Cheers :-)

It seems we're in a good state to submit the proposal and enough
people have expressed interest that I have no doubt we'll have both a)
presenters and b) an audience. In the end that's what matters so I'm
going to submit the proposal as drafted and we'll see what happens.
Thanks everyone for the great suggestions, discussion, and expressions
of support!
Cheers :-)

It looked pretty good to me... I had really no comments, ++ writing
skills. :)
I was thinking.. you mentioned a more complex shield..zigbee.. lcd..
sounds more expensive.
Can we perhaps just build it with an LCD and optionally zigbee, etc?
Also what's the cost per part on those shield PCBs you made up?

Yes, that's what I had in mind. The ZigBee module in particular is a
very expensive part so that would be optional. The shield is designed to
provide (from memory)
* pushbutton input
* LDR
* 2 x reed relay outputs
* 2-line LCD interface
* ZigBee headers
* variable input (potentiometer)
* LED outputs
The second most expensive part is the LCD at about $10, followed by the
reed relays at about $4 each. People could choose not to populate those
particular parts if they want to save some money.
The idea behind the shield is to provide a flexible teaching platform
for people to learn about analog and digital I/O and run example code.
> Also what's the cost per part on those shield PCBs you made up?
Varies dramatically with quantity, but once you get beyond about 40
boards the cost per PCB is way under US$2/board. Not counting tooling
and shipping costs it's more like US$1.15.

The ZigBee module is definitely optional !
The LCD is pluggable, i.e also optional.
The rest of the parts are modest in cost.
A first prototype has been built ... http://twitpic.com/9lhj8

total).
The GitHub project documentation covers this.

then, let's do that.
The current board design will undergo at least another round of
design, based on experience with the first prototype board.
Certainly, the layout of the hardware needs to change a bit.

The proposal has now been submitted so we just have to wait and see what
happens. I'll let everyone know the outcome.
I also highly encourage all of you to submit paper proposals to the main
conf. Speaking at LCA is a great opportunity so go for it.
Mike Beattie
No problem from me, I'm staying conspicuously quiet while the proposal
goes forward, since I'm on the paper review committee that's also being
asked to help decide on miniconfs... I'll be stepping back from decision
on this one, but most happy to contribute to organisation if we're
selected ;)
Apart from that bit of full disclosure, What you've written is great Jon,
fingers crossed!
Mike.
