I suspect this will be a short lived project, because the original project team will hopefully refactor their repo ,(http://github.com/esp8266/arduino) to address the need to download a custom version of the whole of the Arduino IDE.
Recently, I’ve been testing some HM10 and HM11 Bluetooth Low Energy modules for a BLE beacon project. But the problem with these BLE modules is that they come as a bare board, hardly bigger than a postage stamp, which is… Read more ›
I have recently been developing an educational language app for the Victorian School of Languages, Australia. The app – available for download in the iTunes store is an activity based language learning tool suitable for ages 6 and up.
Onewire devices are commonly used with the Arduino, including the excellent DS18x20 thermometer. Unfortunately the OneWire library accesses the micro-controller GPIO hardware directly. This appears to be in order to meet the bus timings when using 16Mhz AVR devices. The… Read more ›
Because the thread on the Arduino forum is now huge, 50 + pages; by popular demand I’ve added a wiki to the GitHub repo which over time should help new users over the initial hurdles See https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki Support for the… Read more ›
Over the last 2 or 3 weeks, I’ve made a lot of changes to the code on GitHub (https://github.com/rogerclarkmelbourne/Arduino_STM32 ) The main addition has been SPI, which generally conforms to the Arduino 1.0.x API, and I have successfully compiled and… Read more ›
Since my last post, my Maple mini clones have arrives and I was able to test whether it was possible to upload via USB to serial. Initially I found that this could be done, but that it only worked intermittently.… Read more ›

By popular request on the Arduino forum, I’m posting a quick tutorial on how to use a generic / unbranded STM32F103 board I bought from an eBay supplier with the Arduino 1.5.x IDE. Before I start, I need to… Read more ›
Just a quick posting about some STM32F1XX based boards which seem to popped up recently on eBay, with Arduino in their description The fist one I noticed was this one TM32F103C8T6 ARM STM32 Minimum System Development Board … Read more ›
Yet another OpenSCAD model. This time its a replacement knob for a camp stove.
I recently bought a AC Power meter module from eBay, (if the item is no longer listed on eBay, try searching on eBay for “AC264V30A”), but the module is designed to be panel mounted and doesn’t have a back, hence… Read more ›
Just thought I’d share the STL and OpenSCAD files for an adjustable angle, lamp bracket for the IKEA Tertial lamp, that I designed and 3D printed for use on a angled drawing board. Lamp Clamp SCAD file Lamp Clamp… Read more ›
As part of an Arduino based AC mains dimmer controller, I’ve been investigating and modelling various zero crossing detectors, and I created an LT Spice model of this circuit which I found here
Just thought I’d post how I managed to setup my Android MK808 for development. Downloaded and installed latest ADK from Google Downloaded and installed latest JRE On MK808In settingsIn Developer options select “USB debugging” (note this setting will be remembered… Read more ›
I bought a cheap USBASP clone Atmel programmer from eBay a few weeks ago, to use with the Arduino IDE. (see images below) The board worked ok, but kept giving errors avrdude: warning: cannot set sck period. please check for… Read more ›
Just a quick post to help anyone else in the same situation… I needed to write a simple console application in C# (to receive serial data and save it to a file), but found that when I copied the application… Read more ›
I spent several hours today looking at Adobe’s new Flash -> HTML5 converter called “CreateJS Toolkit” (see http://www.adobe.com/au/products/flash/flash-to-html5.html ) The premise is that Flash content, (graphics, animation and sound) can be exported for use with the CreateJS suite of open-source… Read more ›

My latest education all. Sun Position Explorer has been submitted to Apple and will hopefully be in the App Store later next week. The app initially just displays a “daylight” map of the world, showing day and night time areas,… Read more ›
I needed weather observation data from the Australian Bureau of Meteorology for an App I’m currently working on. Although the BOM provides observation data for all stations in JSON format, they don’t provide a list of JSON pages etc. So… Read more ›
I noticed a request on the cocos2d-html5 forum for a “dashed line” drawing class, so I wrote this class based on code posted to stackoverflow.
I’ve now uploaded the source code for my first cocos2d-HTML5 game “Traffic Control” to GitHub. https://github.com/synergie7/cocos2d-HTML5-traffic-control As cocos2d-HTML5 is changing all the time, I’ve included cocos2d-HTML5 as a sub project so that the correct version can be downloaded with… Read more ›
Over the last week I’ve been evaluating Cocos2D-HTML5 as a general HTML5 development framework and I find the best way to do an evaluation is to attempt to actually build something. So here is my first Cocos2D-HTML5 game. Click Here… Read more ›
