it's a "blip" more than a "click". interesting. thanks for the info.

Yup, but when it comes from a little buzzer instead of computer speakers, it sounds much more tinny, closer to a click. It's actually the buzzer generating the sine wave in the keyboard case; all you provide to the buzzer from the controller is DC voltage whenever you want it to sound.

Step one complete, now finish that keyboard!

Excellent, I have been doing exactly the same thing recently.
The board on the left is a Leonardo I got at EMF Camp in the UK.
Once I have developed a PCB, I intend to use the Micro as you are.
The main problem I can see, is there is code for using Matrixes on Arduino, and code using the USB functions of the leonardo, but no examples of merging the two together yet.
I will keep an eye on your updates, and will post any updates/code I come up with as I get to those points.
nb. the Uno to the right is not being used, its just attached to my breadboard.

This gave me a great(stupid?) idea.
Why not make a 2-key keyboard, and make a binary > text software.
There is 2 keys on the board, 1 and 0. you type in binary, and the output gets translated into normal readable text.
Man, i'm bored.

Hehe. Would be a great gag gift for programmers. Or up it to three...

I'm still waiting for my bluetooth module to arrive. Darn! it is taking forever.
In the meantime I'm going to have the plate cut. I'll do with a pre-holed PBC and lot's of wires I believe, at least for the first prototype.

I plan to work on a laser cut see through acrylic plate for mine. Won't be as strong, but it should look pretty slick.matt3o wrote:I'm still waiting for my bluetooth module to arrive. Darn! it is taking forever.

Plus I can make/prototype it myself easily.

FINALLY!
The BT module! Now to the soldering!
Where do you guys buy electronics components in EU? Mouser and the like are from US right?

I often buy things from ebay.de, conrad.de or amazon.de.
Which BT module is that? Where did you get it?

Otherwise http://uk.rs-online.com/web/ has a good selection.
Aware they are both UK based, but obviously thats closer than america.

it's not the cheapest, but very well documented and it has a pretty good quality BT module
edit: thanks for the shops suggestions!

As Farnell is business only (I think, could not order) I used this Farnell retailer. Ended up being cheaper, too
