Summer of Open Hardware

[lira.lg]

Hi guys, I am talking with an academic colleague in US about a Summer
of Open Hardware, similar to Google Summer of Code but in small scale.
Other organizations are running similar programs as RUBY, GNOME, KDE.

We are looking for funds from crowdsourcing financing sites. What do
you think about this idea???

[Romain Bazile]

Hello Everybody!

As I want to build for myself a watch, I want get a pcb made by
batchpcb. But it's expensive to do so for just one board.
Thus, I wanted to know if anyone is interested in buying a pcb. I would
have them delivered at my place, and then I would send them back to you
for the real cost. No margin or anything intended here.
Maybe we could do the same for other the others component (like a group
buy for a kit) if anyone is interested.

Cheers,

Romain Bazile

[Sean Lynch]

Yes, definitely in.

Just wanted to chime in here. I had hoped to get the MakerBot watch out as a really great watch, but didn't have the chops to get the power consumption under control. Could really use some rockstar programming.

That being said, it's an awesome looking watch and works as a full on arduino. It's open source and I'm completely in support of you all getting your own boards made!

Actually it's a visually appealing arduino at that.  It has some use as a good looking exposed MCU.

[Patrick Callahan]

I would love to pitch in and also buy a board for a watch.

[Ryan/baslisks]

how much would a board cost?

The power code could use some work - I've worn my watch as a pendant
on my badge for two conventions (Pengicon in Detroit, and Marcon in
Columbus) and it's generated *lots* of buzz, but the batteries only
last about 4 hours. :-(

Quite so!

I've been mulling over in my head a few things - one is that LED
watches of the 1970s were blank except when you'd tap one of the
buttons, when it would light up for a few seconds then go dark again.
Holding that button for a few seconds would get you to 'time set'
mode. Another thing I've been thinking of is what sort of sensor
might make sense in the spare pins by the ICSP port - a tilt sensor
and a light sensor are the first two that come to my mind. One
possible use for a tilt sensor is to see if it could tell if the watch
were being worn on the wrist and held up in the "read my watch"
position (and work for both arms, since I'm a lefty and wear my watch
on my right arm). The light sensor would be useful for determining
ambient light to perhaps save on the battery when displaying the time
in a dark room.

Any other ideas?

I have 2470 atmega168v low power tqfp32 chips I just purchased for ~$1 each. 10 MHz max, they consume very little power.

I can whip up a PCB that uses them..

-Martin

[Adam Mayer]

IIRC correctly, by far the biggest current draw on the watch is the
LEDs. I think Ethan's got the right idea; adaptive brightness and
on-demand rather than constant display. If you really want to keep the
uC power draw down, the best bet is to use a low power external clock
chip (ds1307 or similar) to maintain the time; then you can put the
whole uC to sleep when it's not actively blinking lights. -a

[Romain Bazile]

Hi everybody!

I've started to check the pcb prices on batchpcb, but it was quite expensive (10$ a board + 10$ tooling + shipping).
In the same time, I started designing a new revision for the board. I included a rtc chip (ds1337), as you mentionned adam, as well as a li-ion battery and its charging chip with a micro usb connector (to be able to charge via usb). The frequency has been downgraded to 8MHz.
The spare pins have been discarded, but without much trouble I should be able to change the layout to included the tilt or light sensor (or both!). I really like the tilt sensor idea!
Also, I reduced the switch number to two.

I'll try to upload my eagle files on the makerbot subversion (can I do that?). And having some time to waste, I also played a bit with eagle 3D to make a little video of the original watch (here: http://www.youtube.com/watch?v=hweTRwPgtCo ). It's not really worth viewing, it was more a bit of fun! I'll try to do the same with the new revision, to show it off a little bit

I already ordered a few pcb for the new revision in order to be able to prototype them and see if it works well. I wanted to test them before asking if anyone was interested.

Here is a picture of the new board layout, with the ds1337 located at the top left of the atmega328.





I would be happy to take care of organising a "group buy" for other parts as well.


Cheers everyone,

[Matt Joyce]

I'd probably buy another.  They are kinda nice boards actually.  Even just as an arduino.

[bre pettis]

I learned how to do board layout and routing with this project and it makes me really happy that folks keep going with it. Romain, love the layout you've got and nice Open Source Hardware logo on there! Sweet! I don't have time to redesign the board and make it better. What I do have is infrastructure to get prototype boards done and if they work, put them back into production.

If you all want to pull the board together for a second improved run, I'd be happy to pay for another prototype run of boards and send them to anyone who worked on the design for free and sell the blank boards at cost to anyone else on the list and if they work we'd put the watch kit back into production.

This would be a great example of community open source hardware innovation which would be pretty cool. 

Alternately, if folks want to get them made without MakerBot infrastructure, I'll be the first in line to buy one!

[Jon Hodgins]

I'm in if people are taking another run at the watch. Using the
Makerbot infrastructure seemed to work well last time.

@ Ethan
The code I helped work on and uploaded to the wiki (http://
wiki.makerbot.com/makerbot-watch) already dims the display when not in
use and when one of the buttons is held it takes you to time set mode.
If it is held again it goes to alarm set mode. (aside, I forgot to set
the alarm to be checked when in the display is asleep, it it would
only go off if you turned the display on, oops). This code could be
adjusted for use with only two buttons in the design above.

I like the idea of the accelerometer and light sensor, but how would
they affect the power consumption? Is it possible to get a low power
accelerometer that could be programmed to wake the microcontroller
from sleep? I know one accelerometer I used once(can't think of it
now) allowed two output pins to be programmed to go high on a special
event such as freefall or an axis exceeding a limit. The output could
be then attached to an interrupt of the microcontroller.

For another idea, what about a stretch sensor incorporated into a
wristband, so you could just pull on it to wake it up
Or perhaps a solar cell to help charge the battery and double as a
light sensor.

Bre, your offer is really nice! It's great to be able to use Makerbot infrastructure!

I already ordered 10 prototype board for my revision (that was the lowest order quantity), but it would be great for other revisions (for example when we include the accelerometer before going into production).

In the meanwhile, I can still send a board to anyone (in the limit of what's available!) who wants to try the new revision. they're in production right now, I'm waiting for them!



Martin, I think the atmega168 and atmega328 are pin compatible, so it shouldn't be a problem to use them and adapt the board.


For now, the main problem will be the available pins for others sensors! But maybe we could find some accelerometer to work with i2c (the rtc is already on a i2c bus).

John, the solar cell would be nice. But i'm afraid it will be hard to find a solar cell small enough to fit on the watch yet powerful enough to refill the batteries. But this could be investigated a bit!

I'm not at my place, so I can't upload the design files just yet, but as soon as I'm back, i'll put them on the wiki.

If you pick something like an Analog Devices ADXL345 (see http://www.analog.com/en/mems-sensors/low-g-accelerometers/adxl345/products/product.html) you get "Tap/double tap detection" for free.

Have a read thru the datasheet.  You can enable tap-detect on one or more axes and the detected taps can generate interrupts on one of two interrupt pins.. Think low-power mode where only the ADXL345 is active; double-tap the watch face (z-axis trigger) to wake up the AVR side. :)

The LGA package could be a bit tricky to reflow though.

We can get the watches assembled at Virtex (http://www.virtexassembly.com) here in Austin.   I have an existing business relationship with them, and the representative I talk to is Kevin Kriss.  Great guy, and they do fantastic work:

Take a look at the assembly they did on my Hack The Badge board : http://www.igotu.com/htb

The only downside is that the stencils are a bit expensive, but they are only a one time charge ($300 for stencil ($175 each for two sided boards), $150 for setup Programming fee on the pick-n-place)

I wonder if there are gyros with an analogous feature. I'm thinking
of
pocket-watch-case packaging, and a quick little snap-rotation around
the Z-axis
would make a great gestural control. -- Don Simpson

[Romain Bazile]

Hey all!

Charley, when I first heard about the Makerbot Watch, I found this website and that's what gave me the idea to renew the Makerbot Watch!

I tried to upload my design files to makerbot svn's (foolish play, I should have known I needed a username/password!).
So I put them here: http://www.gromain.info/watch3.zip

I ordered a few weeks ago some boards to test this revision, and as you know, there are 10 of them. I'm planning to keep two for me, so 8 are available.

I'm also ordering the parts necessary to build them. And you know it's cheaper to buy in bulk.
So the question is, is anyone interested in getting a board or the board+parts?

As I already explained, this new rev implement some changes.
The board is now powered via a 110mAh li-polymer battery (coming from Sparkfun). There's a charging chip on board so we can use the micro usb port to charge it.
The ATMEGA328 (or ATMEGA168) is now clocked with a 8MHz crystal, and there's a RTC chip on the i2c bus.
The price of the parts is almost $24 (with the atmega being $4,87... So maybe we can avoid buying them and instead use atmega168.... Martin?) I don't count the board price (it was less than a dollar!).

So, is anyone interested, before getting the new revision built (the one with accelerometer and light sensor... I already have a rough design that I'll share soon!)?


Cheers,


Romain

Given 10 units, there will certainly be savings on ordering all the
LEDs together, the other components much less so, but then you run
into minimum orders and shipping eating into small runs (I only order
from Digikey and Mouser and such 2-3 times a year - in between orders,
I keep a google doc with everything I need for the unfinished projects
on the bench that gets added to every couple of weeks).

When I get the urge to build something now, I skim the doc to see what
I can order from where and combine several projects into one shipment.

As for the next version... I've been playing around with the new chipKIT boards, and besides having a bazillion pins, they also have an RTC clock on-chip (needs a separate crystal, but it runs on minimal power when the rest of the chip is in sleep mode). So now that there's a working gcc port, pic is now an option. -a

Hmm... I was unaware of this line until now.

http://ruggedcircuits.com/blog/2011/05/22/microchip-chipkit-and-arduino-pin-compatibility-analysis/

I see that as much as they've done to ensure compatibility, there are
a few warts that affect what I do (I teach Introductory to Advanced
Arduino workshops when I'm not evangelizing Makerbots)...
specifically, shield compatibility is a risk for me, the lack of the
Wire library is problematic (though solvable), and no PWM for D11 is
definitely an issue (I do a lot with RGB LED control).

It looks to me that Microchip has decided that riding the rising wave
of Arduino is a better course than trying, as so many have, to get an
"Arduino killer" to go anywhere. Even TI with its $4.30 MSP430 is
little more than a footnote.

[Romain Bazile]

Hey!

So, for now, that's 4 of us for a new board (Bre, Ethan, Don and me). So
there's 6 boards left! Come on guys, don't you want your board!
I'll order the parts from digikey next week. I hope to be able to send
everything (and get pictures) in two weeks.
The total price goes down to $20 + $5 of shipping cost. I'll set up a
paypal thing.
I can't wait to have all the parts and to experiment!
I set up a google doc with the part ref. Any advice or comment is
welcome! Here is the link:
https://spreadsheets.google.com/spreadsheet/ccc?key=0AnBxjlowTaKVdGZQeFFTa3pyMERYd1lyYUFEVkVlMGc&hl=en_US&authkey=CO3thaMO
As some parts comes from other places than digikey (the atmega and the
battery), you are of course free to order directly from them (if you
already plan to order parts or whatever). In this case, just tell me, so
I don't end up with too many (expensives) parts! (Though I'll figure a
way to put them to good use!)

Cheers all!

[Romain BAZILE]

Hey everyone!

Great to see so many people wanting a new makerbot watch!
But there's a little itch... As some people wants two boards (and only 10 are available), I don't have enough boards!

So what we can do, so everyone gets at least one board, is to limit the quantity to one per person. If that's okay with everyone, it would be great.
That makes the total board number ordered to 9. I'd like to keep the last one as a backup for mine, but if anyone (who already don't have a board secured) wants to have it, it's okay with me!


Anyway, the digikey order is going out tomorrow. As will the Sparkfun one!

I'll try to get some pics of the boards too!

Hey!

Welcome aboard!

We already got the board parted. But what you can do is order one on batchpcb.com (http://www.batchpcb.com/product_info.php?products_id=61651&check=c23edd9a675b6b99699aa76f2d7dd8df ), it will cost you around $9 + shipping.
If you manage to get a board, i'll be happy to send you a kit of the parts for $20 + $5 shipping.

The digikey order should go out before the end of the week (depending on pay-day here!).


Cheers everyone!

[Martin Bogomolni]

Romain,

I have the mega168's headed your way... 

-M

[o.or...@gmail.com]

Argh. Turns out BatchPCB only does international shipping via FedEx.
For nearly $40 for a square inch sized PCB!

I feel bad about asking this, but...
Is there any chance someone from the group based in USA might order it
and forward it to me?

On an unrelated note...

How come the SQW pin of the DS1337 has been left unconnected?
Might be a good idea to hook it up to the 168 in the next revision, as
it can then be used as an interrupt to wake the Atmel from sleep.

One of the potential uses for that, of course, being a very power-
efficient alarm implemetation. You could also use it to have the Atmel
wake up periodically (once a minute, once every x seconds) and flash
the time, or have it blink the whole ring every few seconds to
indicate a missed alarm (as a notification system of sorts).

Regards,
Ante Vukorepa

[Romain Bazile]

I didn't know you were in Europe!
If you want, I can send you a board (I'll try not to fry the one I have
left!).

As for the DS1337 and its SQW pin, it's just that.... I'm stupid!
Completely forgot about that!
I already implemented the change in the next revision!
(Sometimes, I just want to slam my head against a wall!)

It would be very to have the led flash every minute or so!

As I'm waiting for the part (thanks for the atmega martin!), I've
started to work on the sketch. There are some changes to implement,
mostly in the way we keep time (use of the wire library for i2c
communication with DS1337).

Cheers everyone!

I wish that USPS offered tracking on international shipment packages.

Got another idea for next revision, although i'm not sure how feasible it'll be, routing-wise. It might be a good idea to hook one LED (a red one, if possible) to a free analogue input. That way it can be used with reverse bias, as a photo-diode, for detecting ambient light level (wouldn't be too precise, but it'd at least be able to discern between outdoors, indoors and night).

Why red? Because LEDs typically respond to wavelengths equal to and higher than the one they emit when forward biased. Also, apart from not taking any extra space, they have the advantage of responding more slowly to light intensity changes than "true" photodetectors (which eliminates the need to average out the values in software).

Um. Sorry for being a pest, but...
One more remark.

Why is there a discrete 8 MHz crystal on the rev3 board?
The internal ATmega168 osc should suffice, since it's not being used
for the actual timing (that's why the 1337 is there for, right) and
it's accuracy isn't really that important.

Plus, the internal oscillator can be clocked down all the way to 1
MHz, further reducing the power consumption. And eliminating it from
the board would leave a spot for any number of useful things (a
BMP085, or a simple temperature sensor, or a tilt switch, or two
additional LEDs for AM/PM indication...).

Maybe worth investigating too for rev4.

Ante Vukorepa

Hey all!

Here is a quick update:
I received the atmega from martin! Thanks for that!
If all is okay, I'm supposed to be paid today, so the order is going out....today!
This means I should received everythin next week. I'm moving friday, so I expect the next week to be quite busy. But I plan to pick up during the weekend. So, I'll do everything to send the kit on Monday the 1st of august.
I'll set up the paypal thing next week, when I have the parts!

Cheers all!

For the people who already paid, the boards are going out tomorrow! That was faster than expected!

I'm still waiting to hear from Ethan, Matt and Norm.

Anyway, I'll try to make some nice component list, build tutorial, some documentation as well over the weekend!

I can't wait to build my own board! I still have to find the damn oven, but I got everything else!

Yeah... sorry about that - I just switched jobs three days ago so
shipping the board to my old address would have been bad. I'm about
to go off-line - I'll connect back up the first part of next week.
Sorry about the timing, but it's been a really crazy week.

I went to the link on my laptop running Firefox 4.0 on Ubuntu 11.04
and I don't see a payment button, nor any image files. I looked at
the page source and there seemed to be a lot of IE-compensating code.
Am I just out of luck with the Wiki because I don't run "that" other
OS?

Can you send me a direct link?

Nice! Thank you!

Hopefully my watch will be here by the time I get back from camping
(it's coming to work so someone will be around to collect it). I
definitely want to get it assembled and a new case designed for it in
time for the NYC Maker Faire in September.

Fun times!

My kit is here. I will have to study up on things before I can put it
together and program it, not being an experienced Arduino person. And
not an experienced surface mount person either; how does one cook a
board, again?

In future, I will probably be happy to get a pre-assembled board.

Don't cook it, solder it manually.

Apply some solder to your solder tip (yeah, i know, you're usually taught not to do that, but different rules apply for SMD soldering). Generous-ish amount. Use plenty of flux on the board and hold the component in place with tweezers. Then touch or swipe the soldering iron across the end of the part or the pin and the pad on the board and - voila - it should magically flow between them.

If you've got a good flux, you don't even have to worry about putting too much solder on.

If you don't, keep a desoldering braid handy.

that won't work for the crystal or the USB connector

[Ante Vukorepa]

Worked just fine for me for the USB connector.

It's doable with the crystal, but you have to tin the pads and use A LOT of flux to get the solder to "suck" under the package via surface tension.

Hot-air is usually a better option for the crystal (i usually use my gas-powered Weller for that).

When I said cook, it was because I was thinking about using a reflow oven to solder the board.

But Ante's method is very good and, as we saw with its builds, leads to very good results! And I'm pretty sure that once you've built your board, you'll feel confident enough to build the next one!
