famiLAB proto-board PCB : RFC
« on: February 16, 2013, 11:24:13 AM »
So  -- the recent hackathon has inspired an idea in me.  I have about 10 components on my bread board, and thought it would be nice to solder them up.  And quality being in the details and all, well I'd like them nice and neat on a little circuit board. 


So I looked around, and they aren't that cheap.  So I got this idea..

famiLAB should make its own proto-board PCB

We could get a run of 200 for just over $200.  Then we could charge members $1.00 apiece, and make them available to the public for $3.00 when we conduct solder class.  The whole thing should be a break even situation.  We could make them blue with the famiLAB logo.

See this site:  http://imall.iteadstudio.com/open-pcb/small-batches-pcb.html

I really like the adafruit perma-proto line - including their Raspberry Pi version.

Might be a good thing to use for inspiration for the FamiLAB board...

I love this idea. Its simple, cheap, and easy. Maybe we can bribe Mike B (lensman) or John S into eagling us up a board. :)


Seeed Studio and OSH Park are also good options for PCBs.

Ian's link is a good one.  It shows..  3 boards measuring 54mm by 33 mm for $7.95 .

We can make our own 50 mm by 50 mm boards for $1.00 a board on a run of 200.  If we do a run of 300 boards the price is $170...  $200 if we add in some extras..  or $0.67 a board. 

Dangerous Prototypes makes these boards.. and has all of there layouts available on google code.
I like the idea of having places for some obvious features
1 - power
2 - buttons
3 - diodes
4 - chip row for 7400 attiny chips
5 - basic grids for whatever.

Why not just get some pre-tinned vectorboard? Shit's awesome and cheaper than designing some custom solution just for us. http://www.mindspring.com/~clist/resource/vectface/VCOVector.jpg
I like colors.

1) it would be awesome to have familab brand protoboards, and if they're really about a buck a piece then I think they're totally worth it.
2) AtomicProf's font size is bigger than ours, therefore he is right :p

I really like the idea, but why not make them super cool and make it a source of income not just a break even. Not talking profit but fund raiser for lab needs; if done well.

Tom -- Where did you get the idea that they wouldn't be "[/color]super cool[/size][/color]" ?  of course they will be "[/size][/color]super cool[/size][/color]".  [/size]
[/color]With a run of 300 hundred, or 67 cents a board.  A profit should be pretty easy.  We could even presell them to lab members.  Maybe get most or all of the money up front.[/size]

He suggested break-even for lab members, ~$2 profit for non-members.

Where he = him != me
Where him = AtomicProf

I can hack something up in Eagle, but we need to be specific about we want.  IMO Adafruit covers the generic protoboard to project fairly well, so what's going to be unique about these boards?  (Besides the FamiLOGO, of course...)  The two things that come to mind for me is a place to put a regulator (an LM317 preferred, so we can set whatever voltage we need), and an Arduino/RasPi header for interfacing.


Questions, comments, scathing rebuttal?

Another thought -- maybe a ATMega168/328 area, a protoboard area, and a 7805 area -- that would allow us to substitute in for many Arduino projects.  (OK, OK, gotta go to class now...)

These boards are better because..  they are cheaper, they will be on hand, and they rock.
A-- 50 cm by 50 cm is not that big
B-- I futzed around with OsmondCocoa and put together an idea of the board.
C-- Yes we should center the board around a chip..  20 pins is really about as big as 50 cm by 50 cm is good for.
D-- It doesn't have to use the chip, but using the chip should be convenient.
E-- I like an area for a power regulator.
[/size]F-- I like the idea of being able to easily stack a couple of boards with male-male pins. This would bring up power, gnd and some signals.
[/size]G-- The lower left could be laid out for some common potentiometers.  And what not. 
[/size]
[/size]So I attached an image.  Lets have some comments and improvements (I am sure there are many!)
[/size]
[/size]Lensman -- I've never made a circuit board from a CAD before.  So, great that you will put something together.  (We still have to get approval, but if we have it laid out, that will be easier to get).
[/size]

I went lookin around for cheap arduinos again and found this which I am terribly jealous of:

http://www.protostack.com/boards/microcontroller-boards/atmega168a-development-kit

I would love a clone of this that doesn't cost $20. I love the size of this thing!!! I would want a straight line for ftdi headers, though, instead of the 10pin

Also I am willing to pitch in money for the first batch.
