Escorna CPU 2.12: An open source hardware project geared towards robotics and programming for kids.

The basic Escornabot can be programmed to perform a series of actions using the robot's buttons. From this point of view, imagination is the only limit on possibility.

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.

atmega8-328 prototype board: good voltage filtering function

This board was created for the mcudude library and has good voltage filtering, reducing reset time via a c10 capacitor (10nF!!) on the dtr line of a ch340 system. It would be nice to solder a precision socket under the x1 oscillator, it gives you the opportunity to try different frequencies (useful for rs232 communication for example)​

Schematic PCB

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.
