Independent keyboard designer and maker based in Japan.
I design compact custom keyboards that combine ortholinear layouts, standard keycap compatibility, and integrated pointing-stick input — the input style widely known as TrackPoint™ (Techmech keys has no affiliation with Lenovo). My projects extend from physical products to firmware, documentation, and software for real-world demonstrations.
日本で自作キーボードの設計・製造・販売を行っています。格子配列、標準キーキャップ互換、ポインティングスティックによる操作体験を軸に、実機で検証しながら製品を開発しています。

- Compact custom keyboard products centered on the OLSK60 series.
- Ortholinear layouts designed to work with commonly available keycap sets.
- Integrated pointing-stick user experiences that keep pointer movement close to typing.
- Firmware, documentation, and demonstration software for physical products.
- Reaching for a mouse interrupts typing. A pointing stick built into the keyboard keeps cursor control on the home row.
- An ortholinear grid does not have to require custom keycaps. OLSK60 is laid out so commonly available keycap sets fit.
- A dedicated case limits an owner's choices. GH60 compatibility opens the existing ecosystem of cases instead.
- Ideas are validated on physical hardware, repeated prototypes, and real daily use — and the product, documentation, and demonstration experience are designed together.
OLSK60 v2.1 is the main Techmech keys product: a 60% ortholinear keyboard with standard keycap compatibility and an integrated pointing stick. It is designed for GH60-compatible cases, so users can combine the keyboard with a broad range of cases and keycap sets while keeping pointer input within the keyboard. OLSK60 v2.1 is designed, produced, and sold by Techmech keys, with purchase pages available on BOOTH and 遊舎工房.
OLSK60 INPUT LAB is demonstration software for exhibitions and retail settings. It visualizes keyboard and pointer input, provides typing tests, and supports kiosk-style Windows operation so visitors can experience the product without setup friction. The project also connects with Raw HID and Vial workflows without documenting the product's internal input implementation.
1U Rotary Encoder Switch is a reusable KiCad symbol and footprint for placing a rotary encoder in a Cherry MX switch position. The library was independently measured and created, is used in OLSK60, and is published as an open-hardware asset under CERN-OHL-P-2.0. This does not mean the full OLSK60 product design is open hardware.
- Fixed extended user-keycode conversion in RMK so User16 through User31 are handled correctly in VIA/Vial conversion (HaoboGu/rmk#928).
- Added ClearEeprom handling and VIA/Vial mapping to RMK (HaoboGu/rmk#931).
Both changes were submitted with corresponding tests and merged upstream.
