Monitor for equal voltage at the terminals of two 12V batteries.

Let’s take a look at this interesting All-in-one Starter Kit for Pico 2—a kit designed for learning electronics and programming, ideal for beginners and beyond. It allows users to begin their journey with the Pico 2 RP2350 processor in a simple and fun way. The kit comes in a small suitcase measuring 195 × 170 × 46 mm. Inside, there’s a single board equipped with as many as 17 sensors or modules serving various functions. It also features a 2.4″ full-color TFT touchscreen.

This is a twin delta loop antenna designed for the 1200MHz band for HAM radio practitioners. It can be used by soldering an SMA connector.

This is a relatively cheap complete Tesla coil driver, so we only need a primary and secondary coil to build functional Tesla coil.

This is a 3D printable boat, used to support two 3V DC motor and one Servo motor to turn the sail.

Another electronic project.

Using this electronic circuit, a very simple pulse generator can be made, using a 4066 circuit.

In this tutorial, I will show you guys how I designed and assembled the humidifier circuit into the 3D model.

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.

A balance indicator for audio systems.

This is a great small portable radio. You probably can't find a cheaper radio on the market than this with similar features.

A type of indicator circuit for batteries

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