No, I mean the tray you have to keep the switches in, I don't see a link for your Tinkercad files. I'd like to have that tray printed so I can try this out on my own. I see the pictures, and the links for the Arduino files, but not the switch blocks or the tray.

Oh wait, nevermind, I see the link in a later post. Thanks!

Could you post a link for the Tinkercad file for your switch bracket? I would love to get it printed so I can check it out for myself. Thanks! Do you mean the blocks I used between switches and keycaps? There is one of them in shared Tinkercad link I posted earlier. It should contain all parts I used. The keycap adapters aren't perfect or even good solution for connecting the keycaps. I just noticed yesterday that my "," key isn't working properly and I can't easily check what's the problem because I can't remove the keycap. So removable keycaps would be nice. When I print out your parts and get the switches, I'll put one together and look at it. I have a couple of ideas on how to attach the keys better so they align more correctly but I need to see how it all fits together when I make it as well. This may take a bit, I have to wait a little to get the parts I need. |

Could you shear the pictures in high res as a zip file then I can edit your post cos I can post hi res pictures.The pictures of the keyboard upside down with the wires and diodes on you can't see properly,the pictures are too small.
I can use Cloudinary on the forum,everyone can use it but you have to sign up on there website and add the settings from there site on the forum for the plugin to work,it would be easier for me to edit your post,If you share the original photos...?

Great, that's why I shared the models so they can be changed. Please let us know how your changes work when done. |

Yes, I'll get the hi res versions of the images when I've got time. |

Here are couple higher resolution pictures of the wires   First layer wiring was in my first post too:  Columns connect to the higher connector of the switch  Switch’s lower connector is connected to the diode (blue) which is connected to the wire (green).   |

I'm no hardware buff so what made you choose the Arduino micro ATmega32U4? I was going to try and use a off the shelf wireless keyboard decoder (JeTech). Once I read your post I now find that I'm looking at all sorts including the Adafriut Feather (Blue tooth) option to fulfil my wireless requirement. I'm not even sure how I'm going to sync the existing dongle I have for the keyboard I purchased. Totally confused as to which way to jump. So many flavours to choose from. Help that's what I need.

The Atmega32U4 seems to be one of the most 'plug and play' Arduinos meant for this purpose and the one likely for most people to turn to for this kind of project. You can't really solder a wireless keyboard decoder in with a hardware keyboard without a wireless encoder which sort of makes little sense for a short range project like this, though if you can find off the shelf components that can be wired in this manner, more power to you!
I'm working on a variant of this that has a 4 port USB hub built in, so I have two more external USB ports, and I'm going to wire the second port on the right to one of the unsoldered pads on the internal hub so I'll have 2 more additional external ports, an internal port wired to the Arduino and the last port wired to the 2nd port. Only trouble may be power, but what I may do is just jump power from the other port in parallel and use diodes so they don't feed back into the Mini.

Thanks for the explanation. I went with a powered hub to look like the 1541 floppy and thats where the keyboard dongle resides. There does seem to be a shortage of USB ports on the mini. I await with anticipation for the next chapter in your keyboard mod.

I really like it. I only wish I had the nerve to cut up my keyboard to make one!
Perhaps if I could get a spare from somewhere...

What would be even nicer, would be a set of 3d printed keys, then people could perform this mod without chopping up their c64... Perhaps one of these printed at 50% would do the trick? www.thingiverse.com/thing:2025280 |

Stupid me went and ordered the wrong switches. The video looked like they were a bit too tall, so I thought 6x6x8 switches would be tall enough but I had no idea how much of a difference 2mm would make. I'm going to order two batches of switches 10mm and 9mm to see which ones fit better but I have to play the waiting game ordering them from Amazon. Otherwise, I'd be done by now!
I've toyed with the idea of fabricating an entire keyboard top from scratch with interlocking keys so they automatically square themselves up, but I'll need to spend several hours in Blender working out the design of the overlay and the keys themselves.
On the plus side, I'm almost done working out the internal USB hub connections. I've been busy the last couple of weeks or I'd have probably finished at least that part for now, but I blew out my JTAG by soldering it backwards by mistake so I have to wait until payday to pick up a new one.

I've thought about 3d Printed keys, problem is the symbols on the top and front of the keys and trying to color match them. I'm sure there are filaments you can get that will match the color nicely. One of the problems is lining up the keys so they're all straight and that's tricky too. After I've performed this mod, I'm going to be puzzling out some new designs including keys that might help, such as keys with alignment rails built into them. When I get the time to sit down. Right now my Mini is in pieces while I'm waiting for parts to arrive.
