SteelBeauty: Laser Cut, StainlessSteel, 65%

Geeeeeeeeeeeeee, so many wires!
Awesome work man!
I'm kinda paranoiac with exposed wires and short circuits though ...

you took too much time to design the PCB I had to be creative

Easy, I think I'll finish it up to this sunday ...
And sorry for your lost (the teensy)
 

[Matt3o]

FINISHED! And 100% working!





My gratitude goes to Hasu and his exceptional work with the keyboard firmwares!

[Broadmonkey]

I honestly would rather buy this than most standardized keyboard. It's looking really good, just change the phillips screws

I honestly would rather buy this than most standardized keyboard. It's looking really good, just change the phillips screws

I've been considering using something like these for a keyboard project:



Bought some custom cap-head stainless steel screws for a motorcycle restoration project, those were neat but the tops were too tall.

Edit: Source is http://www.trfastenings.com/pages/Metric+Socket+Countersunk+Head+Screws

[Matt3o]

I tried many screws but at the end the phillips are those that give me the most perestroika feeling

The ones suggested by broadmonkey are a bit problematic on my case because I don't have enough clearance to completely inset them into the case top (which is also the plate).

also consider it's 100% stainless steel... a hell to work with (I broke 3 threading bits)

Threading bits? Y U NO USE NUTS??

[Matt3o]

yes, next time I'll use nuts for sure!

[hasu]

Congrats! Great job. It looks lovely.

[Broadmonkey]

I was thinking more about something like this

[TheSoulhunter]

You could use something like this...



It has a thread inside to insert a screw from the back

- No thread tapping, just drilling
- Flat and minimalistic at the faceplate
- Screw head hidden on the underside

[Tarzan]

There are a variety of fastening options, some more difficult to source than others.  I have a lot of respect for anyone tackling a project like this, I'm just hoping I can borrow (copy shamelessly) some of the ideas when I finally muster up the nerve to start a similar project!

this is a nice idea! I'll use these for my next project (alps 60%)

[agodinhost]

For those wiling to build one keyboard like this one posted by Matt3o here comes my 5 cents:

Complete PCB:
https://github.com/agodinhost/KiCad/tree/master/Matt3o

The same PCB with a Teensy board attached:
https://github.com/agodinhost/KiCad/tree/master/Matt3o-Teensy2

There is no USB connector in these boards - only the 2.54mm header to connect and plug the USB wherever you like.

Right now Matt3o Matt3o is trying to find a way to attach the USB connector into his case. Any idea is welcome ...

[Matt3o]

Thanks agodinhost for working and posting this! You did and exceptional work.

I don't think there's enough interest for the SMD version but the teensy is tempting if we find a way to fit the usb cable.

Okay, let me know.
It would be sad to trash it away so soon ...

I'm working on a 60% board based on this same idea (Cherry and Alps into the same board). Any interest, please, note me or open one new topic.

[domoaligato]

I know somewhere I saw a link to the wiki page you created based on your work with hard wiring but I can not seem to find it now?

I want to create a alps gh60 hard wired but I am basically stuck planning and understanding the wiring matrices and how this all ties to the teensy controller.

would someone mind giving a brief explanation of how the wiring connects together?

I think I'll soon start a "group build" (not "buy") for a 60% alps keyboard (hard wire+teensy) code named whitefox stay tuned.

I have looked at that thread and this one a lot in the last few weeks.



the switches I am harvesting are yellow omron alps and are all mounted upside down in the existing board.
which side +/- do the diodes attach to and how do I tell which side is positive and which is negative?

once I get the board to a point when I have it laid out like lowpoly does how do I determine which wires connect to which pins on the teensy to be compatible with the default gh60 poker layout firmware?

Awesome job on the MX one. Very interested to see how the "whitefox" goes.

Thanks! I look forward to seeing your progress. I am getting married in a little over 2 weeks and I have to pay for the gh60 GB so it may be some time before I can get started.

Seems that the PCB I designed for you is going to be trashed away ...

hope not. these things just take some time. don't be negative!

[metalliqaz]

If you have a PCB use it for goodness sake!  The one and only reason to direct wire is to avoid having to fab a board

I am doing it to get good at soldering again because I haven't done it in 10 years.

Any idea what the official name for this part is in English? If I translate it I get bolt bus assuming that the name I have for it is even correct, but that just gives me an actual bus as result I'm prototyping my own Dell AT102W case and this could come in handy to replace the nut I have at the bottom

*Found it! In English it's called a blind nut. The only downside is that the outside diameter is ~5mm so those are some big holes ^^
You can have them very short: http://www.hobbyking.com/hobbyking/store/__8227__blind_nut_m3_10pcs_.html
Or longer: http://www.ebay.com/itm/25PC-M3-METRIC-NUT-RIVET-BLIND-NUTS-INSERTS-ALUMINUM-/280707253169

Btw, hobbyking has really cool screws, bolts and nuts in nylon and different colors of metal.

[yasuo]

nice

[yasuo]

Whether it is inside the copper (black cable)?

in the second link they are just rivet inserts, they are not threaded.

[Paranoid]

Ah good that you noticed Gotta be more thorough next search ^^

[alaricljs]

in the second link they are just rivet inserts, they are not threaded.

Not true, they are rivet style nut inserts w/ M3 threads.  The are attached just like rivets with a special rivet nut insert tool that squashes them down, but there are some threads in there.

you sure they are threaded? I can't see threads from the pics.

[alaricljs]

"minimum 6 turns"  so very few of them, and they don't show the end where they are, they show the end that gets squished.  ed:  ok they do show them, but the fidelity is absolute crap.

[TheSoulhunter]

Wasn't thinking of blind-rivet-nuts as these usually don't have a "head" and are meant to expand...
What I meant is "Innengewindehülse mit Linsenkopf/Flachkopf" which translates to "Inside threaded bushing/bolt with pan-head/flat-head":

[Matt3o]

where the hell do you get those?!

[bueller]

where the hell do you get those?!

I've been looking at getting something like that for my build but I'm a little bit worried that if overtightened you'd never get the screw out again.

[Binge]

Kailet, who made my 2TU, had used clear polycarb for the center of his "vicki" style case, and it's had some great aesthetic applications like case LEDs.

[Tarzan]

where the hell do you get those?!

They look similar to the blind fasteners I ordered from McMaster-Carr:



Nice domed surface on the blank side, though!  I don't have pics of the ones I ordered, they're still on the way.

any recomen controller besides TEENSY 2.0 beacuse  in my country no one sells TEENSY if buy at pjrc will be time consuming and expensive that shipping
but i see on my country any seller Arduino Fio ATmega328P Microcontroller what recomended? qute big
or other suggestions

This shop
Which good controller

Thanks

[alaricljs]

Just ebay search atmega32u4 and pick something that works for you.

Avoid the Arduino micro-controllers, the bootloader is incompatible with a lot of the firmware's people are using. You can get around it by reloading another bootloader but you need an ISP box and that's just more money down the tube. I'm using a board from MattairTech with the same AVR chip, fair bit larger than the Teensy but it also has a lot more pinout's for things like external USB connectors. Very configurable as well, they will load it with whichever bootloader you request and will add headers if requested too.

[alaricljs]

I use a teensy as an ISP, typically cheaper than an actual ISP.  Any other similar MCU board can do the same.  http://dorkbotpdx.org/wiki/teensy_2_0_as_avr_isp_programmer

yasuo:  We don't know what country you're in if you don't tell us... we also can't fix the realities of prices/shipping.

[Neebio]

where the hell do you get those?!

Smallest is 6mm head diameter, 4mm barrel diameter, 6.5mm barrel length, that takes a 3m bolt.

[RabRhee]

Really superb looking keyboard.

With a full stainless steel body, could this be the Delorean of keyboards? What happens when it hits 88 wpm?

Anyway I'm using that same board as base to create another PCB for one 60% keyboard design (same idea, cherry and alps into the same board).

I'd love to see that, in this "65%" design

I gotta say Matt3o, that is one sexy beast.  What can I say though I am a sucker for raw stainless.
