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。

FluxPad is a custom-designed 12-key macropad built around the Seeed XIAO RP2040, featuring a rotary encoder, and an OLED status display.

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

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.

The TCBK40 is a fully open-source, high-performance 40% mechanical keyboard designed from the ground up by Tuka Customs. Built with a strong focus on compact efficiency, clean PCB architecture, and maker accessibility, this project aims to deliver a powerful yet minimal typing platform for enthusiasts, developers, and hardware creators. From a hardware perspective, the project emphasizes accessibility. Components are selected to balance performance and availability, enabling makers around the world to source parts and build their own units without unnecessary complexity. The design also considers ease of assembly, making it approachable for both experienced builders and those entering the custom keyboard space. TCBK40 is built for those who want control over their tools, and the freedom to shape their own hardware.

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

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.

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