[Erich] is the middle of building a new competition sumo bot for 2018. He’s trying to make this one as open and low-cost as humanly possible. So far it’s going pretty well, and the quest to make DIY ...

What is it about useless machines that makes them so attractive to build? After all, they’re meant to be low-key enraging. At this point, the name of the game is more about giving that faceless enemy ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

Seeed Studio reBot Arm B601-DM is a fully open-source 6-axis robotic arm (plus a parallel gripper) designed to lower the ...

Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...

Arduino library for the KY-040 Encoder. This library allows the user to connect one or more encoders to any of the interrupt pins supported by your board. The user may then add rotaries that will each ...

const int encoderPinsA[NUM_ENCODERS] = { 10, 8, 6, 4, 2 }; // Encoder A pins; any PCINT pin const int encoderPinsB[NUM_ENCODERS] = { 11, 9, 7, 5, 3 }; // Encoder B pins; arbitrary - pick any IO #ifdef ...

Abstract: Multimotor structures and transmissions exhibit inherent complexity and vulnerability that integrate multiple magnetic components and multi-phase structures. This article proposes a ...

For possibly the last time, car lovers from across the Coast and country have united for the Devonport Motor Show.
