For Half-Life Fans, the original Static Mine! Material: Versatile natural black plastic Size : 6.03 x 3.55 x 5.28cm. This mini-robot being designed reproduces the behavior of the original static mine in the Half-Life video game (see video below). The robotic version is under design and includes: an RGB diode, a tilt switch (shock sensor), a motor to operate the legs of the mine, a toggle switch, an ATTiny chip on which I inject C code via Arduino to control 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.
