Microchip announced MPLAB® Harmony Graphics Composer (MHGC), a modern and flexible graphical user interface (GUI) composer tool.

Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced the MPLAB® Harmony Graphics Composer (MHGC), a modern and flexible graphical user interface (GUI) composer tool. MHGC is a free development tool for developing GUIs for all PIC32 microcontrollers through Microchip’s Harmony Configurator and MPLAB X Integrated Development Environment (IDE). The software allows anyone to create branded content using the Harmony Graphics Library, in conjunction with their custom assets, to create GUIs in a What-You-See-is-What-You-Get (WYSIWYG) design model, without complex and cumbersome coding.

SubPos: a WiFi Positioning Solution for Places GPS Can’t Reach

532351464008485561

SubPos Positioning System – A “dataless” Wi-Fi positioning system that can be used anywhere GPS can’t.

SubPos is an indoor positioning system that can be used in various environments such as metro lines, shopping malls, carparks, art galleries or even conference centers; essentially anywhere GPS doesn’t penetrate. It could also be integrated into an array of IoT enabled devices, from access points to Wi-Fi enabled light-bulbs.

When the world’s lifeforms are forced into subterranean dwellings due to nuclear fallout, evolution into lizard people or warming of the Earth, we will require a simple method for determining our position underground. In our current age, we are still working out the intricacies associated with determining our location in areas where GPS cannot reach

1000 steps Servo motor

FF25RDAIPBH3405.MEDIUM

TheSuperSewcio @ instructables.com shows us how to control a servo motor in high precision using Arduino:

In many project like CNC machines people use stepper motors. They are probably always more expensive than servos. They can rotate 360°, 1 step = 1,8° (mostly). Servos can rotate only from 0° to 180°, 1 step = 1°. But why are they working this way, inside them we will find potentiometer which rotates as servo (up to 180°), but have 1024 steps.

Running NodeMCU on a battery

ESP8266 low power consumption revisited:

Using Wi-Fi is a convenient way to link your newly created IoT device into your existing IT infrastructure – including cloud services – but it also has a drawback. Wi-Fi’s demand for power usually makes battery operation impractical for any real deployment. I have been able to get around this issue for most of my projects (e.g. the train and the smart shelf described on this blog) because they are for demonstration purposes only, requiring the battery to last no longer than a few hours.

384:LED – Mini RGB LED array

led_matrix_rgb

Mini (1.44” x 0.94” or 24mm x 37mm) 8X16 RGB LED Array. 128 RGB LEDs with three LED chip each gives 384.

For this project I designed two PCBs. A control PCB and a LED PCB. My goal was to fit them both in a small panel inside a 5×5 cm square to use cheap Chinese Manufacturing offers. Both PCB to have the same size and will be connected with 50mil / 1.27mm pin headers. The LED PCB will be stacked on top of the control PCB.

Oscilloscope Vertical Position and Offset explained

This video describes the function of the vertical position and vertical offset controls of a modern digital oscilloscope. It shows how using the offset control can provide valuable visibility of the DC bias and small signal waveform simultaneously, which can be very valuable in many applications.
