3 Phase AC Motor Controller

This project made using MC3PHAC from NXP Semiconductor. The project generates 6 PWM signals for 3 Phase AC Motor controller. It’s very easy to make professional VFD combining with Intelligent Power Module (IPM) or 3 Phase IGBT/MOSFET with Gate driver. The board provides 6 PWM signals for the IPM or IGBT Inverter and also brake signal. Also this board works in stand-alone mode and doesn’t require any software programming/coding.

The MC3PHAC is a high-performance monolithic intelligent motor controller designed specifically to meet the requirements for low-cost, variable-speed, 3-phase ac motor control systems. The device is adaptable and configurable, based on its environment. It contains all of the active functions required to implement the control portion of an open loop, 3-phase ac motor drive. One of the unique aspects of this board is that although it is adaptable and configurable based on its environment, it does not require any software development. This makes the MC3PHAC a perfect fit for customer applications requiring ac motor control but with limited or no software resources available.

Included in the MC3PHAC are protective features consisting of dc bus voltage monitoring and a system fault input that will immediately disable the PWM module upon detection of a system fault.

Pulse Generator For Stepper Controller Using AD654

This stepper pulse generator project is an easy solution for stepper controller drive. It’s a very important tool and can be used to drive stepper in standalone mode. It generates square wave pulses in frequency range 0-50Khz. This project has multiple features which are a must for stepper controller. It has on board frequency generator with wide span of frequency, Slide switch for direction control and jumper for enable or disables the stepper controller. AD654 is heart of the project and its generate the pulse for stepper controller, output frequency 0-50Khz, higher frequency output is possible by changing CT capacitor value connected between pin 6 and 7. Refer to data sheet of AD654 for alteration.

Romeo BLE

Romeo BLE – An Arduino Based Powerful Robot Control Board With Bluetooth 4.0

Romeo BLE is an all-in-one Arduino based control board specially designed for robotics applications from DFRobot. This platform is open source and it’s powered by thousands of publicly available open-sourced codes. Romeo BLE can easily be expanded using Arduino shields. The most important feature—Bluetooth 4.0 wireless communication, allows the board to receive commands via Bluetooth. So, users can now use their smartphone, tablet, or computer to interact with the control board.

Control Robot From Smartphones by Bluetooth 4.0

Even the codes can be uploaded over Bluetooth a USB Bluno Link adapter, without requiring any wired USB connection between the board and a PC. This is a great advantage for mobile applications where codes are debugged and uploaded frequently.

The Romeo BLE also includes two integrated two-channel DC motor drivers and wireless sockets, which makes project development more hassle-free. One can start the project immediately without needing an additional motor driver circuitry. The motor driving section also supports extra servos which need more current.

There are two ways to power the Romeo BLE board. But, the polarity must be correct. Otherwise, the board may get permanently damaged as there exists no reverse polarity protection. The two powering methods are:

  • Power from USB: Plug in the USB cable to the Romeo controller from a power source (i.e. wall jack or computer). If the input voltage and current are sufficient, the Romeo BLE board should turn on and a LED should light up. While powered from USB, do NOT connect anything else like motor, servo etc. except LED. Because the USB can only provide 500mA current which is certainly not enough for driving loads like motors.
  • Power from External Power Supply: Connect the ground wire from your supply to the screw terminal labeled “GND” on Romeo board, and then connect the positive wire from your supply to the screw terminal labeled “VIN”. The maximum acceptable input voltage is 23 volts. Do not exceed this value anyway.

Sound to RC Servo Driver

This project is designed for Animatronics and Puppeteer applications, however it can be used in other applications like sound responsive toys, robots etc. Especially this project helps to move the jaw or mouth of animatronics creature.

The project moves RC servo once receives any kind of sound.  Rotation angle depends on sound level, more the sound level more the movement. Movement of the servo is proportional to sound level.

Circuit has 4 channel servo drivers, First channel is driven by sound, and rest 3 RC servos controlled by on board trimmer potentiometer, these 3 channels helps to drive other movement of animatronics figure.

Sound Received by microphone is convered to DC voltage, PIC16F72 microcontroller converts DC voltage into RC PWM signal. Circuits works with 6V DC , advisable to use battery for low jitter.

Temperature Controlled Fan With LED Status

This is a simple fan controller with single LED temperature status light using an ATtiny85 microcontroller and DS18B20 temperature sensor. The fan is turned on/off based on temperature sensed and the controller goes in sleep mode when the temperature drop below a predefined threshold.

Simple ATtiny85 fan controller to turn a fan on/off based on temperature. Includes an LED as a temperature indicator. LED is dim at start of fan on temperature and blinks when above a max temperature. Fan is not PWM controlled since I am using a small 5V fan which is quiet running at 100%. The controller is in sleep state while the temperature is below the minimum threshold and wakes up every ~8 seconds to recheck the temperature. When temperature is above minimum threshold, the controller will stay awake checking every second till the temperature falls below the minimum threshold. The code uses ds18b20 library by Davide Gironi.

A DC Motor Controller with Control Leds

Boris Landoni writes about a new open source project a DC motor controller with control LEDs:

The circuit board we are presenting this time is based on the dual-bridge driver L298N, in a traditionally mounted version in a Multiwatt container with 15 staggered pins; it has two terminal blocks for attaching to DC motors or the coils of a bipolar stepper motor and a terminal block for powering logics and motors. Each of the two output channels of the circuit can provide a maximum current of 2 A, which is enough to drive two 2 A direct current motors or a bipolar stepper motor absorbing 2 A per phase.
