Looking for 2 people to purchase 2 of the 3 break out boards I ordered for a Teensy 2.0. It has all the holes with solder pads for the legs to solder a Teensy 2.0 into with traces leading to another set of pads for soldering wires. It also has holes in the corners to mounting with 6-32 thread screws via standard PC motherboard standoffs.
Cost will be $3.40 + shipping. Conus only please. Now to be considered for this please post a comment explaining your current build, estimated time of completion, and current state of said build. The reason for this is because with my lack of electronics knowledge I want the first 2 to go to someone who has the ability to test and debug any issues with the current state of the break out boards.
If anyone wants to use the design untested it can be found at this threat reply #29 (http://geekhack.org/index.php?topic=45587.0).
Edit: Many thanks to OldDataHands for doing the cad work for this. Without him I could never and gotten this to work.

Edit2: Forgot to take the extra I paid for quicker shipping out before I divided cost by 3 for price per board. Updated.

This is so cool, I'd buy one but have no projects so hopefully someone who can test it out ASAP will pick it up!! GLWS!!

That little board looks wicked!
Shouldn't there be another hole near the top right leg of the letter "H"?
I have been contemplating building another Teensy converter or 2, but would hate to hide that gem. It should be installed in a clear box if there is such a thing.

If you are referring to the inside legs on the teensy which would be E6 on the bottom and not sure what the top one is but they follow a trace to the far bottom right and top right corner just to the left of the mount holes.
Here is a pic of the final boards, one being mounted onto standard PC standoffs.

What does the bottom look like?
I have always used these 4 holes:

Tomorrow I will get my Teensy desoldered and have a closer inspection and be checking this out. Will report back on this but counting the holes they are all there.
-
What does the bottom look like?
The pic of 3 has the bottom... of the 3 shown, the left is one side and the right is the other. Since this is a simple breakout board, top vs bottom doesn't matter as long as all your pins are lined up, the teensy has bilateral symmetry.

I think it's awesomely responsible of you as a seller, to make sure the buyer is getting something that he can actually use.
Too many of us (including me of course) buy on impulse because something is cool and we hope to make good use of it someday, only to dump the goodie in a box somewhere and resell it after a year of inaction.

Am I the only one who think these would make awesome keychains!!
I'm serious....no spam, thread crapping or trolling intended.

It wouldn't be too hard to make a neat design and have them made. Could also include rounded corners (or make the whole thing round) so that you don't destroy your leg/pocket. That's a whole other topic tho.
-
What do you do with a breakout board?
-
It can be used to simplify attaching one device to another, or testing multiple copies of device A. In this case, the purpose is to have physical tie-down points (the 4 standoff holes) and easy access to solder/resolder all the pin locations of a Teensy 2.0 without risk of damage to the Teensy.
-
What do you do with a breakout board?
The purpose of this board was so I could make use of the Teensy 2.0 in a hard wire matrix with a steel case and not have to worry about the wrong things shorting out and/or relying on an adhesive for mounting.
-
If you have trouble finding someone to test them in the US I'll take one for a future build. Currently working on a 65% and a game pad for a disabled friend of mine.
-
Wouldn't it be easier to provide a slot for the pins of a Teensy presoldered to a board, and then you could just plug it in when needed and unplug it later?

If I didn't already have my own monkey fist around a wooden bead for a keychain I would only be selling one of these.

Only problem with that is the headers would add too much height to fit in most cases. For a future build I want to try making a couple of additional layers for the bottom of the case to act as both keyboard feet and a place to house the controller and USB.

The plate I am using won't allow the use of a PCB for the matrix but I am wondering if there is room to mount the teensy under this breakout board. Will have to check that out tomorrow after work.

I'd love a board but I'm outside the CONUS :(

Pm sent to you bueller.

I'd love to buy one off you, to complete my 122-key terminal board project, but realistically that will probably be a winter break project. Any plans to make more PCBs? Or can I replicate your order to the fab shop, "once more, with feeling?"

I apologize Greystroke but the 2 spares I have are spoken for. Sorry for the lack of updates in the OP. But feel free to use the files that are available in the link in the OP.

Thanks, Melvang!
I may end up ordering a dozen of these, as I have some Alps boards that I want to convert to USB. Although I think a Teensy is overkill to convert DIN/PS2 to USB, that's the only solution I've seen that doesn't involve using DIN-to-PS2 + PS2-to-USB adapters in a kludgey bundle of wire.
-
Not a problem. Just one thing if you post build logs on any of this please give OldDataHands credit for the breakout board. It was my idea but his design and work on the design end.

Absolutely!
By the way, the ordering process for OSH Park was pain free! These are the first custom PCBs I've ever ordered, really opens my eyes to what's possible nowadays for the home hobbyist.
-
They were my first custom pcbs myself. Just wait till you get them in. They look amazing in person. So much so mine will be visible in my project.

I was also inspired by your mounting solution, so I ordered a couple of M2x050 taps and a bag of brass standoffs. As nice as the mini-PCB looks in the pictures, I'm planning on leaving it without a case, so anyone opening the Model M or Focus keyboard in the future will see it immediately.
Imitation is the sincerest form of flattery, right? :p
Edit: M3x050 taps...
-
Gotcha. I just double checked the stand offs that I am going to be using on mine and the external threads on them are a M3x.5 and the internal threads are a 6-32. Which is what the breakout board was designed to accept.

Good to know, I just found an electronics shop around the corner that sells every standoff imaginable so this should make life much easier.
