For Half-Life Fans, the original version of the HEV Charger. Material: Versatile natural black plastic. Size 7.69 x 13.2 x 2.84 cm. This mini robot being designed replicates the behavior of the original HEV Charger in the Half-Life video game. The robotic version is under development and includes: an orange diode (orange glow in the body), a white diode (HEV eye),two motors to animate the charger eye driven by an L393D (see video below), a toggle switch, an ATTiny83 chip on which I inject Arduino C code to drive everything. Power supply: Lithium battery: 3.3v - Note: the robotic version requires iterations at the 3D Printing level, in electronics (PCB) and in code. I therefore sell the non-robotic version to finance the development of the robotic version
