Get ready for MPLAB Express

image1-600x450

Chas from iradan.com discuss about MPLAB Express, the new cloud IDE from Microchip for PIC microcontrollers. He writes:

I credit the maker movement with bringing electronics back from the crusty old and lonely electronics hobby back into the main stream. The Arduino is the micro of choice for this army of makers and I conceded it made sense… you install the IDE, plugged in your board into the USB port and a couple clicks later and you have an LED blinking.. the most exciting blinking LED you’d ever seen in most cases. I stuck with the PIC micros because I didn’t see any need to put back on the training wheels.

SolarBoost – Make Your Own USB Solar Mobile Charger

solar_charger

SolarBoost is an open source smart interface that allows you to build your own powerful and portable solar charger for your phone and other mobile devices. It has two USB ports and can provide 5V @ 2A at each of them and is controlled by a 8-bit 32MHz Microchip PIC microcontroller. It is also equipped with various protection features like soft-start, over-temperature, over-charge, over-discharge, short-circuit and current limiter.

SolarBoost is the first open-hardware and open-source smart interface designed to give you the freedom and flexibility to make your own battery- and solar-powered power bank for charging cellphones, tablets, MP3 players, speakers, GPS navigators, and much more. Use it to also power your DIY electronics projects!

24405880851_58ab1dd5fb

Microchip Technology announced MPLAB Xpress, a new cloud based development environment to provide an easy way to get started with PIC microcontrollers.

Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced its MPLAB® Xpress Cloud-based Integrated Development Environment (IDE). This online development platform is the easiest way to get started with PIC® microcontrollers (MCUs), with zero downloads, sign-in or setup needed to start designing. Microchip’s free, cloud-based IDE brings the most popular features of the award-winning MPLAB X IDE to Internet-connected PCs, laptops or tablets.

Wake-U-Up System

system_overview

Zhiyong Hao and Zhuo Chen from Cornell Univercity build A PIC-based Alarm clock system that is different from most alarm clocks known.

This project is aimed to design a ‘Sleep and Wake-up Assistant’. Different from a normal alarm clocks which can only make noise, this alarm clock is designed to wake up a person in a comfortable and effective way by involving sound, light stimulation, motion detection and vibration. The functions of this alarm system are:

CHIPINO – The Microchip PIC Based Arduino Style Module

1368013441

Chipino is an electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, students, technicians, engineers and anyone else interested in creating interactive gadgets.

Chipino is not designed to replace Arduino, it’s just another option. Arduino is a great platform based on the Atmel microcontrollers. But many people prefer the Microchip PIC microcontrollers. There is a seemingly endless supply of software examples and application notes available for the Microchip PICs but a common hardware platform was missing.

Pixie – 3W chainable smart LED Pixel

2741-06

Ytai Ben-Tsvi @ ytai-mer.blogspot.com build a PIC based 3W LED Driver that is chainable. He writes:

LED Pixel: The Pixie is a color LED module, allowing an external controller to change its color and brightness dynamically.
Chainable: The module is designed so that you can chain many of them and control each one individually. If you know NeoPixels, this concept should be clear, but in case you don’t, imagine you want to build a project that requires 50 LEDs to be individually controlled. Naively, you would need to power each on of them individually, then connect each one of them individually to a controller. This would require tons of wiring, many pins on the controller, each one possibly driven by a specialized peripheral, such as UART or PWM. In short, this is not practical. With the Pixie, being chainable, you connect the first LED’s input pins to power and a single control pin (serial TX) on the controller. Then you connect the first LED’s output pins (power, ground, data) to the input of the second LED, and so on. Each Pixie in the chain consumes its own data, then relays the rest of the data down the chain, so the controller can control each Pixie individually, without being connected to each one.

RC Servo Driver 0-5V

Servo_Driver_Photo

0 – 5V Servo Controller project will control a hobby type servo motor connected to it via a preset or external DC source.  This kit will be ideal add on in animatronics and motion control application.

This is a simple but a useful circuit to control a single servo motor.  Its an ideal add on to a RC Hobbyist tool kit. The DC input to this circuit should be 5 to 6 VDC.  DC signal is given to this board at connector marked CN1 (+V and GND).   You can also feed in a variable DC signal source at the other two pins on this connector to control the servo.  To use this signal source you need to place the Jumper link at J1 in the E position.  Alternatively, you can also control the servo motor by preset PR1 mounted on the PCB.  For this you need to place the Jumper link in the I position at J1.A Servo motor is connected at connector marked CN2 on the PCB.  This connector has all the pins clearly marked for connection to the servo.LED D1 is a power on indicator ,  Diode D2 provides a reverse polarity protection for the Microcontroller.

Specifications

  • Microcontroller based design for greater flexibility and ease of control
  • Single Servo control via clearly marked berg connector
  • Clearly marked jumper to select signal source to control the Servo
  • Onboard preset for ready to control option for this kit
  • Power-on LED indicator
  • Diode protection for reverse polarity connection of DC supply to the PCB
  • Four mounting holes 3.2 mm each
  • PCB dimensions 45 mm x 32 mm

Build Your Own PICKit 2 Programmer

7316084

pulsetronics.blogspot.com.ng has build a nice version of PICKIT Programmer:

This is my PICkit 2 clone design. Its based on a simplified version of the Microchip PICkit 2 schematic and only supports 5v parts. It works with all the Microchip software including MPLAB, MPLABX,the PICkit 2 GUI Programming software and the PICkit 2 command line software.

It can be used with the PICkit 2 GUI Terminal Software and the PICkit 2 GUI Logic Analyzer. Best of all its an all leaded design that you can build in about an hour if you have of the parts.

Because this design is simplified and uses a fixed voltage reference, the programmer voltage cannot be controlled by the PICkit 2 software settings to lower the voltage. It also cannot do the “Vpp First” mode which in rare cases you may need to re-program a PIC that has a very fast internal oscillator and internal MCLR enabled.
