RGB LED PWM Demo on Petalinux

In this tutorial we are going to use the same hardware descriptor from the previous post and build an RGB LED PWM Demo driven by Petalinux. To do this we will need a Linux machine with Petalinux SDK installed on it. In this experiment we will be using SDK 2017.3 but any newer revisions up […]

Arty Z7 Zynq 7020 – ‘Hello World’

Having hardware and software configurable platform gives the ultimate flexibility. Having FPGA fabric and two ARM cores integrated into a single System-On-Chip (SoC) gives benefits of the two (hardware and software) worlds, compact size, advanced optimisation of such integration, reduces the time for development effort, simplifies subsequent testing, verification and validation. Today we are reviewing […]

A Handsoldered PCB Running Embedded Linux

A foreword

Homemade Linux boards have always been just a pipedream for many due to prohibitive complexity of both hardware and firmware. The situation hasn’t even changed with the arrival of Raspberry Pi and Beaglebone boards which still can’t be replicated in home labs either due to the absence of design files, proprietary components in […]

Lumunardo in White Case and Blue Screen

Introducing a more stylish look of the enclosure made of white PLA material and translucent blue front and rear panels. It is very hard to find acrylic material other than transparent white with 2mm thickness so we had to modify the top and bottom shells to be able to fit 3mm thick panels.

Luminardo: Designing Enclosure

The idea of making enclosure fully out of acrylic panels was abandoned due to ‘squarish’ look of the final product. We really wanted to create something a little bit more stylish and this is why the most obvious choice was 3D printing. That way it was possible to make rounded corners and streamline shape. However, […]

A Luminardo Board Revamp: Revision 2.1

This is a second spin of Luminardo boards with the focus on elimination minor mistakes found in the revision 1.0. A motion sensor is fully integrated with the PCB this is why the board has an inflow on top of its outline. Also an obsolete inductor is replaced with the one of a similar footprint […]

A 16S8D VFD Panel Revamp: Revision 2.0

This is a deep redesign of MVFD 16S8D Panel Rev.1.0 project which fixes minor and major issues and finally solves the fundamental problem of some parts becoming obsolete. Let’s reiterate the reasons which were the main driving forces of the project to come into existence:

– Single power source (+5V) which makes it possible to […]

Adding HM-10 Support to Arduino-Based CC-Debugger

After numerous reports of failures to flash HM-10 Bluetooth modules with the Arduino CC-Debugger we were lucky enough to get the module for experimentation and troubleshooting.

HM-10 BLE Module

To our surprise the tool indeed was refusing to communicate with the HM-10. Even ‘Info’ button kept reporting 0 Kb of flash memory […]

Flashing BLE112 with Arduino-Based CC-Debugger

As it is always the case, many products from Texas Instruments require a CC-Debugger to flash program memory. Bluegiga’s BLE112 module is not an exception. But when one compares BLE112 and CC-Debugger prices things don’t look bright anymore – there is a little sense (if any) to pay $50 US dollars for a CC-Debugger to […]

The BlueButton – Envisaging Enclosure

Continuing the development cycle of the BlueButton today we are going to create an enclosure prototype which potentially could be 3D printed. The goal would be to fit PCBA into a plastic box comprising of three parts: a top shell, a bottom shell and a round button. All 3D bodies will be created by extrusion […]
