The Linear Keyboard provides the amazing feel of a full mechanical keyboard and allows you to take its small form factor on the go!

In this tutorial I am going to create a chaser circuit that can drive 20 or more LEDs using 555 timer IC and CD4017 decade counter.

A 16 Key Macropad with RGB, 2 Encoders, a OLED, and more!

syvrcpad is a 4x3 (4 by 3) macropad with a rotary encoder E11 and has 0.91 OLED Display. The macropad uses XIAO RP2040 as its micro controller.

Macro pad in the shape of a snowflake. PCB can also be processed into a plate to fix the keyswitch. The circular key layout is a rare shape not found in other macro pads. Slim design so that the keys look good. Enjoy the design and feel that you cannot experience with any other keyboard. --- 雪の結晶の形をしたマクロパッド。 PCBはキースイッチを固定するプレートにも加工できます。 円形のキー配列は他のマクロパッドでは見られない希少な形状です。 キーが映えるようにスリムなデザインにしました。 他のキーボードでは体験できないデザインと使用感をお楽しみください。

Many vintage computers use a keyboard matrix for input. This solution replaces a missing keyboard with a cheap PS/2 keyboard.

Is a PCB to make picorectangle easier to make for a boxx style controller
