Solderpoints left: 243

Bad news: Three columns in one day...
Good news: I have learned a pretty good technique for doing this and the rest will be bearable to solder;)

Yup, the LED matrix will be a sight to be seen but thinking about it doesn't really bring any worries to mind anymore. I had an moment of clarity earlier when thinking about the matrix layout and all the options, and as it turns out I acctually talked about the solution before but never saw it from ...

UPDATE!

Finally done with the mounting of LEDs and stopped for a moment to take some close up photos of yesterdays progress.

The pile of LEDs and sockets, for some days this seemed to ...

Thank you very much Sirs!
I feel that I have been lurking these forums for long enough and after all material I have been soaking in it's about time I give something back.

Here's a progress shot of the LEDs coming into place:

UPDATE!

The next big chapter after finishing the plate and the initial switchmodding is wiring of the matrix(es).
There will be two matrixes:
1. Switch matrix; cols:17 rows:6
2. LED matrix; cols:17 rows:6

These will be identical in layout but separated from each other so that I can control them ...

Switches, switches and switches...and did i mention switches?

What I did:
*Unmout with paperclip tool
*Place stickers
*Lubricate 6 points in each switch housing
*Change springs to from black to 62g and reds (and som white klickies)
*Assemble
*Lubricate stabz
*Dampen the larger keycaps
*Mount O ...

UPDATE!

So, now that I got all the parts needed I can finally get some physical work done and first of all I took care of the chassis. Lets start with a couple of pictures and talk about the important notes on my design.

UPDATE!
Its been a long wait but finally my chassis has arrived and I have learned a lesson in what shipping company I will ban and never use again!

Stab dim...Very interesting but luckily fixable...
Lets keep things in motion and take a look at the latest pictures of the chassis:

The reason i bring this up is really just because it's very confusing and I will make sure to add a note in my picture stating that this dim is no good.
But, as i said, it might be a good thing to edit the sources that the majority of newcomers uses and those being the dwg/dxf- files linked from ...

Kind of OT:
Last nights tryouts with stabilizers got me thinking. Isn't 0,75mm a to big offset towards the "led-side" of the switch? Looking at my pictures knowing that all dimensions are correct I feel there's room for improvement here. Please mighty gurus and old foxes, if you read this, give it a ...

Thank you sir, I can tell you that the dimensions over at GH and especially the files for phantom says 0.03" offset from the top which is 0,761998476mm and length 0.55" which is 13,97mm and looking at my cutout file tells me something else is wrong:

https://dl.dropboxusercontent.com/u/39367418 ...

I'm happy to be able to say that i got the moountingplate the other day and that the dimensions for switch cutout where absolutely perfect! No problem getting the switch in place and not the smallest wiggle at all! One small problem though is that the stabilizer holes in a strange way seems to be a ...

My logo on has come to life!

UPDATE!

Today the mountingplate arrived at my friends house. (ordered through the same guy who is milling the chassis)

Even thou it's upside down it seems like a nice and clean cut. Now i only hope ...

Welcome home Teensy ++2.0!

https://dl.dropboxusercontent.com/u/39367418/Tangentbord%20Teeny%20engineer/6-komponenter/teensy%2B%2B2.jpg
It's a little bit longer than the regular Teensy 2.0 and measures approx: 51,6 x 18,3mm and thickness 1,7mm (PCB).


I also got the god news from my friend that ...

Another week, another milestone...(Yeah!)

Tonight I sent the cad files for chassis and feets to the workshop!

Small changes since last, a chamfer was added on top and bottom edges. a little ...

Here's a bunch of renders showing the chassis as of today, please leave a comment! I'm all ears if you finds something odd or if you just wonder how i plan to fit things.

UPDATE!

Just got the info from my friend helping me with manufacturing, material for chassis is collected! LDX stainless steel ;)
Also got this snapshot of a tryout for the front logo:

And here's the video I was talking about earlier today!

A small video of a circuit controlling a set of LEDs, big thanks to you Peter for your kind help and knowledge!

If you where to ask the average Joe I guess he would't get the point with some LEDs turning on and off, but to us ...

A little note on the side (a glimpse into the near future) just because I´m really excited about it:

This weekend I ordered a Teensy ++2 with will replace the Teensy 2.0 and bring me from 25 to 46pins! This allows me to build the perfect matrix of 6x17, I will also have a lots of pins left to be ...

I agree that it's a real pain ;-) One thing that calms me down in the doubts of this dimension is the K65 keyboard that I myself measured to 13,93mm and that I have had a hands on dealing with unmounting switches in this keyboard. I guess the only problem could be with tolerances from the ...

Thanks Matt3o, good to know!

Moving on to the design phase:

The plate was drawn using cherry mx cutout resourses found on DT and GH and then laid out to fit my layout. I decided to go with Costar stabilizers after a search for availability on both costar and cherry and since the cherry ones seemed hard to find my choice fell ...

Many interesting ergonomic designs there! Thank you jacobolus.
But as i said in the OP the designing phase of layout is already closed, and besides, the plate is on its way to me in a few days i hope=)

Now back to the story, starting from the beginning:

Layout and functions is the primary things ...

Finding new interests and new forums is probably best described as being infected with a serious disease which can only be cured with medicine.The disease in this case is the ...

Have a look into shift registers, basically a chip that you connect to your teensy with 3 pins + V and G. then these registers can provide you with lets say 16 PWM pins for controlling a matrix of leds. Im about to dig deep into this when my build starts (very soon!)

I would just like to show you guys what I´m working on here in Sweden. It´s a highly personal layout for my needs when working with CAD. I´m also aiming to get it compact taking up less space on the desk without taking away too much of the comfort from a TK board.
