Free prototyping boards

[Wm Leler]

Laen has offered to donate some of the extra free board space on his PCB orders to some prototyping boards for people to use at the electronics lab at TechShop / OpenTechSpace.  If you have any ideas of what kinds of boards would be useful, please let us know soon.

Of course, this would be for general-purpose prototyping boards for everyone to use. If you have a board for a specific board you want fabricated, you should buy some space in his next order.

Subject: Donating protoboards to OpenTechSpace

Since I invariably have some free space on the PCB orders, I thought a good way to make it useful would be to throw a bunch of prototyping boards in and donate them to OpenTechSpace.

I'm doing an order on February 2nd.  What kind of boards do you guys think would be useful?

* SOIC and MSOP to DIP adapters.
* TQFP breakout boards
* SOT-23 to DIP adapters

Are there any others you'd like to see?

Thanks,
-Laen

ken says,

"oh yes if we can  get a half the size of the altoids can or 1/3 with an IC dip 18pin  and a Vcc and Vee rail would be very useful gear to do all sort of proto_typing"

I'll see if I can get some more information ... would it be better to post back over here, or are you monitoring the techshop forum?

Years ago I made big panel with breakout for almost every type of
surface mount chip to 0.1 inch grid. I still have a few panels left
here, and they've been very useful over the years for whenever I want to
prototype something and the chip only come in surface mount.

I could dig it up and chop into many small files.

I think breakouts for the common surface mount packages would be the thing to do. It is easy to get proto boards for through hole stuff. Much more difficult if you want to prototype something that you have to get in surface mount. I'm not sure how to prioritize which packages to do firsl. Perhaps someone has a better idea than I do about which packages would be the most useful.

I think having a big pile of package breakout boards would
be awesome, but I don't think we have to choose between that
and other stuff. Paul, if you could find that artwork that
would be great. Laen, if you want to run an extra panel
with this on it, I can pay for it.

Okay, here's what I have:
* TQFP32/QFN32 to DIP
* TQFP44 to DIP
* TQFP48 to DIP
* MSOP10/TSSOP8 to DIP
* SOIC28 to DIP (works with everything down to SOIC8)
* LGA14 to DIP (used by accelerometers)

Any other requests?

Paul- What else did you put on your panel?

overlap your collection.

Now let me be clear I'm not recommending that Paul try this without
someone testing it first, but would it be possible to post these on
one of the wikis?

[interrupt0x00]

how about these? I think I only see the MSOP10/TSSOP8 to DIP over on
the dorkbots' site..

http://dorkbotpdx.org/wiki/creative_commons_licensed_circuit_boards

can they be posted anywhere?

Sorry, meant to send this to the group:

You could always add to the list on our DorkbotPDX site and then link to it from the OTS wiki.
