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.

posture correction robot

It's common for computer users to bend over in front of a screen, which can eventually lead to back problems. There are various gadgets on the market that solve this problem by constantly reminding users to sit up straight, but most of them are not fun. So I made a fun little tool for this problem.

NanoClon 0.01: used to assemble mClon type robots

This circuit has everything you need to assemble a mClon-style robot, without the need to find the missing Arduino circuit from RobotDyn used in the ShieldClon version.

Components can be SMD or THT, except the boost circuit/lithium battery charge controller is SMD, the 1206 and 0805 components are larger than the usual 0603 and 0402). You can choose not to solder the boost smd component and just solder the Bat-Vcc selector on the bottom to use the power bank.

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.
