This intriguing but festive Christmas-themed PCB gift card provides a feature-packed home automation interface thanks to its complementary mobile application (Android).

SSTC based on LabCoatz version, with adjustable Schmitt trigger oscillator. With a properly adjusted device, the length of the scattered spark exceeds 20 cm.

This small 20W RGB video light can be fully 3D printed and is very simple to operate. You can switch on the light by pressing the button on the side once. By rotating the encoder, we can cycle through the hue value. After pushing the encoder, we can switch to the brightness control mode. We can adjust the brightness of the LED by rotating the encoder. If we push the encoder button again, we can switch back to the hue control mode. It's a one-knob operation.

This is a light bulb indicator kit that blinks with music.

The Pinecil LED Ring adds three LED lights to the Pinecil soldering iron to improve soldering in dark environments. This addition to the Pinecil soldering iron fits just above the soldering tip on the plastic area by friction so no glueing is required. It is easy to assemble and add to the iron using another soldering iron to connect the internals.

These candles flicker like a real candles and can be activated with an actual flame

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。

This is a USB-C snowflake lamp designed based on the SGL8022W dimming IC, which is ready to use upon power supply and free programming.

I made this project with stuff that I have in boxes, a project that attracts attention. Who doesn't like LEDs?
