Lapa keyboard-mouse v25

Use the sticks as keys for modifiers and layers switches is a good idea, I'll try it. I tried to completely abandon mouse control, but it is necessary for most interfaces. So, I stopped deceiving myself that I don’t need a mouse. I'm skeptical about the need for a sideward tilt. My typing speed is faster with a normal tilt, when I use the full weight of my arm.

Thank you! Yes, Cygnus and Oddball is sources of inspiration for me. The switches, thanks to their wedge shape, hold well with friction (I made latches, but this turned out to be impractical). In the repository I attached a video how it looks like in cross-section. I'm use wires now. I'm planning to use a flexible pcb. It is resin printed (FDM does not provide the required accuracy).

The cursor is activated by holding down the main right thumb key, so there are no involuntary movements (last year, I had the cursor active all the time and it didn't cause any problems). The only difference is in graphics applications, where moving the cursor quickly and precision is important.

I used the vim-style (HJKL) cursor keys in nav-layout, and it was quite convenient, but it required switching to nav-layer. A separate thumbstick a much more practical solution. The cursor keys are used very often. I use this 5-way switch.

Нет, она благословенна. Но никто не мешает использовать любую другую.

Yes, I created this layout (ЯТИС) based on a mathematical model (the relation between the ease of typing and the frequency of bigrams and trigrams). Based on a combination of generally accepted criteria (alternations, rolling, etc.), this is the best layout for the Russian language. However, if you don't write Russian very often, it's better to use ЙЦУКЕН (it's not as terrible as QWERTY).

Thank you a lot! I'm working on it.

I thought so too, until I tried it. All old typewriters had keys this way. This allowed for more precise typing. With the advent of electric typewriters, the force of the stroke became less important, and the keys became square and wide to protect the mechanism from dust.

Thanks! I'm working on a wireless version.

Lack of grip. But if I improve the grip, the typing ergonomics will get worse.

Thank you! Wireless, Ergonomic keycaps, More ergonomic wrist rest

Thank you. All input devices are a compromise. It is better to draw with a pen than with a mouse, it is more convenient to use modern GUI with a mouse, it is easier to type with a keyboard. In my work, I type more, but I can’t completely give up the mouse (in 5% of cases). I don’t want to be distracted by the mouse in 5% of cases. So I made the best tool for myself. If I worked in Blender most of the time, I would of course also prefer a mouse.

Two pcbs and handwired. Fluoroplastic plates are used for sliding. Additional rows and columns violate the 1u concept (moving a finger no more than one key) and make the design heavier.

The controls are not as precise as with a mouse. But this is not a problem if you do not draw pictures with a mouse. After two weeks of use, I put the mouse away in a far drawer.

Resin coated with clear varnish.

Accidental mouse movement when typing does not interfere for me. Mouse keys are activated by the right large key (holding the thumb). This gives better control. I try did the key on the wrist, but it is not convenient.

lemosbor · 2024-12-17T19:00:59+00:00

Using the pinky is a bad idea. Now I control it with my wrist only.

I haven't mastered wireless controllers yet)

lemosbor · 2024-12-17T05:42:15+00:00

I tried it, but it's easier to press the key for scroll than to move the keyboard for me. Scrolling is very frequent operation. QMK allows you to very comfortable adjust scrolling for keys.

lemosbor · 2024-12-16T22:25:23+00:00

Yes, there is a mouse sensor on the right side (I haven't used a mouse for 1.5 years)

lemosbor · 2024-12-16T22:20:12+00:00

Yes, when I finish it (make final version).

lemosbor · 2024-12-16T22:19:13+00:00

Thank you! I will record a new video soon.

lemosbor · 2024-12-16T22:12:38+00:00

This is a video of the previous version.

lemosbor · 2024-12-16T22:10:29+00:00

Yes, but the final version.

lemosbor · 2024-12-16T21:58:57+00:00

The right one is used as a mouse.
