Split Single-phase Energy Meter: Affordable remote energy monitoring for your entire home

The CircuitSetup Split Single Phase Energy Meter is an affordable, accurate remote energy monitoring device for your entire home. It monitors energy usage in real time, independent of power company meters, and can be easily connected to any wireless microcontroller (such as ESP8266 or ESP32) to transmit energy data to programs such as EmonCMS. It can also be used to monitor solar systems to track the amount of electricity you generate from the sun. It uses a secure current transformer clamp to sample current - no AC wiring required.

The Skull CTF: Guessing Skull Game Tool

The Skull is a Capture the Flag (CTF) puzzle that invites you to explore the innards of the AVR architecture. It has multiple stages that may keep you busy for days or even weeks as you flex your brain muscles and apply them to her riddles. Unless, of course, your mind loses its grip on reality and you fall into a swirling void of madness with no anchor. In this case, it may take you longer. To keep your head above water, you need three things: the ability to read and understand Arduino code, a willingness to spend some time reading the ATtiny45 datasheet, and basic programming skills.

RoverWing: Adafruit Feathe expansion board that makes building complex robots easy

The RoverWing is an expansion board (or "wing", following Adafruit's terminology) for the Adafruit Feather board that provides motor drivers that can handle 6-12 V motors, an inertial motion unit (IMU), and common servos, acoustics, etc. for mobile robots. Connectivity ports for GPS, GPS and other peripherals. Affordable, with powerful Arduino libraries and excellent documentation. It also contains a microcontroller with preloaded firmware to control these peripherals, which communicates with the Feather board using the I²C protocol, thereby freeing up the Feather board's resources for other uses.
