Options for integrated pointing device

Options exist for all three of them.

For a trackpoint version, checkout the buzzard. I also recently added beta-level support for trackpoints to zmk. So you can build a wireless trackpoint split keyboard.

I am also working on a corne clone with trackpoint support.

You can come to the zmk discord pointing-devices channel to discuss the topic with more people.

A message from /r/ErgoMechKeyboards

Amazing. Thank you for creating this community here.

I haven’t been back to Reddit since the blackouts started and the only subreddits I miss were this one and one other one.

So I’m happy we have a new home.

I also appreciate and fully agree with the way you handled the move and your decision making.

Thank you for being honest, transparent and considerate.

Next step is to move all my posts from Reddit to here.

Where should I start?

I recommend you watch this stream of nicel (nice nano creator) assembling a keyboard:

He also has a keyboard store that sells keyboards that are optimized for wireless and have many components pre-soldered.

You will need to make a lot of decisions:

  • Do you want a number row or do you want to use layers for numbers so that you don’t have to stretch?
  • Do you want a second pinky column (esc, shift, …) or use homerow mods or thumb keys for those.
  • How many thumb keys do you want? (Only three are realistically usable unless you have huge hands)
  • Do you want regular MX switches or low profile Choc switches?
  • How much row stagger do you want?

It can be overwhelming and unfortunately the Reddit community is blacked out. That’s where all the answers lie until we can get a searchable archive.

Some keyboard designs you would want to look into are:

  • corne
  • lily58
  • Sofle
  • Chocofi

And of course, if you get stuck, make sure to ask here. Other people will have the same questions and we need to build up the knowledge base on this platform.

Any tips on dealing with symbols for programming?

I put brackets as combos of pointing and middle finger.

On the left half the homerow combo is for (. On the right half, it’s for ).

And the other symbols are on a layer. I optimized it it to make common programming symbols easy to type.

And I found that practicing typing quickly on speedcoder.com really helped me.

At first you have to think about what key to press to switch the layer and then what key to press to get true symbol you need.

But after a while, your brain learns the combination of movements.

So you just express the intention of a symbol and your fingers execute the symbol.

First build - 1 key is not working

Try to narrow down where the problem is.

First use tweezers to connect the two switch pads together and see if it outputs the key.

This way you can test that the PCB works.

If that works, try the same with the contacts inside the hotswap socket.

If that works, try switching the hotswap socket.

I don’t think the sweep has diodes. But if it does, check if the direction is correct.

How typical is it to use thumb keys for shift?

I tried shift on the thumbs, but didn’t like it.

I am using homerow mod shift. If you are on zmk try urob’s timeless homerow mods:

Another alternative to try would be one-shot-shift. Instead of holding the shift key while typing the letter you want to shift, you would tap the shift key once and then tap the key you want to shift.

After that one key press the keyboard goes back to typing unshifted characters.

I haven’t been able to try this, because my keyboard doesn’t have the 6th column with the shift key.

But I’ll try it on my next build.

Wrist Rest recommendations for Lily 58?

You got a lot of great recommendations.

I just wanted to throw in that you shouldn’t actually put your wrists on the wrist rests, because it can lead to carpal tunnel syndrome.

Instead you should rest the meaty part of your palm. So it’s better to refer to them in your head as “palm rests”.

And for ideal ergonomics you should only rest on them when you are not typing. When you are typing your hands should be floating.

And of course, your table height should be at or below elbow level so that your elbows are 90 degrees or less.

What kind of socket to use ?

I am a bit confused by your photo and the other comment.

Usually you installed female headers on the board and male pins on the controller.

Most keyboard designs also ask for the controller to be installed with the components facing down and not up like in your image.

So make sure to double check the correct direction for your keyboard before turning it on.

For the display you can use the same female headers and then just make the male pins that you solder to the display longer.

I recommend watching this stream of a lily58 keyboard build. It’s done by the creator of the nice nano.

He shows how to properly solder controllers, sockets, diodes and so on. o
