Panoramic photo robot with Bluetooth control, based on Arduino MEGA 2560
Since everything in this schematic is either public or super simple I leave it as public too.
**NOT for commercial use!**
This project of mine has just been started so there is no firmware nor software (PC, Android) available yet. Currently I don't plan to make it public like the Arduino shield design.
If you like the s...

Demonstrating simulations of a DC and a two phase stepper motor.
#### Model of a generic DC motor.
The model has the motor positive and negative power supply terminals.
It also has three outputs.
TORQUE is a voltage representing the motor torque scaled as 1V/Nm.
ANGVEL is a voltage representing the angular velocity of the motor scaled as 1V/RADIAN/s.
POSITION is a voltage...

Home ∕ Electronics Projects ∕ Z80 Retrocomputing 5 – Single Stepper for RC2014
I'm very interested with the Dr. Scott's project TIL311 Bus Monitor Board and this Step Executor Board.
This time I'd like to make this board with my favorite parts like pod with tab control, alternate Toggle switch for single stepper.
Therefore I decided to make my own...
A stepped-motor controller for three steppers using Trinamics 2130 compatible "SilentStepSticks". Also supports upto two hobby servos and has two power FETs for on/off control of loads (including inductive ones).
Can be used stand-alone using the ESP32 on-board which supports WiFi and a web-based UI when running the [companion software called RBotFirmware](https://github.com/robdobsn/RBotFirmware)...
This is a Stepper HAT for Raspberry Pi or stand-alone use. It is the board I'm currently using in my SandBot [SandBot](https://robdobson.com/2018/08/a-new-sandbot/) and provides two SilentStepStick TMC2100 positions, two FET drivers for LED light strip or similar and two servo ports. Software is here: [RBotFirmware](https://github.com/robdobsn/RBotFirmware)
