Foldable Lamp Box - Night Light - reacts to sound and has adjustable brightness, USB port for charging, runs 24h on Battery - ATtiny85 processor - 25x WS2812 leds

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

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.

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.

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

Simple Cute Dog Keychain with LED's

Diyas are the heart of major Indian festivals, most notably Diwali, the "Festival of Lights." Lighting rows of diyas during Diwali symbolizes the victory of Lord Rama over Ravana and the welcoming of prosperity and Godess Lakshmi (the goddess of wealth). Tired of oily Diyas? In this tutorial, I will show you guys how I created these super simple 3D printed Diwali Diyas which are safe, non greasy, reusable, easy to make and will last forever.

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.

In this tutorial, I am going to show you guys how to design this "Transformers PCB Badge" and how to solder the components to it.

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.
