MVFD Panel and Regular Arduino

Today we are publishing photos of fully assembled and tested MVFD 16S8D Panel, Rev 2.0. The board on the pictures is fully populated with components which means that apart from displaying alphanumeric information it can measure ambient light intensity, emit simple ‘beep’, receive signals from an IR remote control and shine with an RGB LED. […]

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 which […]

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 […]

Arducam Rev.C – First Encounter

This article was prepared back in October 2013 but remained unpublished all these months. At first, when we got Arducam Rev.C in possession its rich set of features and performance inspired us greatly. However, just within a few days the interested moved on, became dim and then quickly faded away. It simply turned out that […]

Mini Maker Faire 2014

Just recently we had an opportunity to participate in Sydney’s Mini Maker Faire 2014. This was the second event of a kind being organised at Powerhouse Museum in Sydney. The decision to take part has been made spontaneously and one only week before ‘the day’ which, to some extent, contributed to our poor performance and […]

Quiz System DIY Arduino Project for a Budget Price

This time our task was to build a Quiz System (also known as ‘Quiz Buzzer’ or ‘Quiz Show’). The real challenge was in meeting two major requirements: being really inexpensive and looking attractive and ‘factory-made’ at the same time as the project was intended for use in elementary school. To our surprise, it became almost […]

Firmware for Pilot Display

The firmware of Pilot Display unit comprises of two parts: bootloader and main application. Bootloader simplifies the process of main application upgrade – once the bootloader is programmed, there is no need in external programmers to do firmware upgrades. Source code of the main application is designed as a sketch for very popular Arduino platform […]

First Pilot Display PCB is Assembled

First Pilot Display PCB is finally assembled and tested. As it usually happens with revisions 1.0 there are several things that have been overlooked during design. Good news is that all issues are minor and don’t impact main functionality. Here are the discovered issues:

a) First of all, FT232 is not powered when USB cable […]

Bluetooth for Dummies: Domesticating RFComm

Knowing RFComm port number to connect to we are fully set for our final step – to establish RFComm communication channel. Before we can send RFComm specific commands we need to establish L2CAP connection to RFComm the same way as it has been already described in ‘Establishing connection to SDP’. The only difference is that […]

Bluetooth for Dummies: Getting Data from SDP

As a result of effort in previous post we now armed with knowdledge what has to be done in order to connect to Bluetooth SDP (Service Discovery Protocol). All we need to get from SDP is a RFComm channel number to connect to, the rest information provided by SDP service while it is a subject […]
