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 light bulb indicator kit that blinks with music.

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.

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 edges of the acrylic are illuminated to make letters and pictures stand out.

I designed and made this light bar for my printer for printing at night.
