Package ManagerAll modern Linux distributions come with a package manager such as Yum or RPM. The Linux distribution included on the Arduino Yun is no exception. It uses OPKG (Open PacKaGe manager).To get an upto date list of package you use the comm...
Requirement Before integrating LEDs I have to revise the communication protocol since the necessary information was not present before. Furthermore some properties are missing. The protocol should be:Future proofSecureSafe against transmission e...
In this post I will talk about the blood pressure measurement subsystemThe main components of this subsystem are the heart beat detector a continuous rotation servo a force sensor resistor The idea behind this experimental blood pressure measure...
I just received an dimmable LED (LOHAS 20W LED Chip). I plan on running a few test programs, starting with the ones that Infineon provide, while I wait for my recessed can whip extension to arrive and I will start prototyping the lamp. Here is a...
I've done many attempts to build and execute my own C program on the atmelsama5d4 xplained ultra board.And today is the big day. Thanks to the tutorial on mikrocontroller-software.de, I was able to cross-compile and run my first binary. H...
Currently... Whilst Hans was busy coding, Matilda was looking into power requirements. She was worried that the batteries might take a long time to deliver so wanted to order them long before they would be needed. DevicePower RequiredArduin...
I recognized that I tend to post only positive results but at the same time I learn a lot from the mistakes of others I decided to devote this blog to my time wasting effort of interfacing 1-Wire components from node.js. Several evenings I read blog ...
Unfortunately I have gotten stuck on my project and stuffed the genie back in his lamp for a short while. I am currently working with the Infineon RGB Shield and have run into multiple issues. I am trying to run a single 5mm Red LED with it. I realiz...
We're halfway through the story. It's time to close chapter 2. Sound and Light In chapter 1 I turned a broken vintage turntable into a working one. The defect AC motor was thrown out and replaced by a microcontroller drive...
When I was younger my Dad used to listen to the shipping forecast on the radio so he could plan his fishing and sailing trips. Given the limited vocabulary it should be possible to use a speech to text processor to convert this to a digital form. But...

Since realising that I could do some of the hard work for interpreting the weather APIs in Python I thought I'd check out my options for IDEs. I've been brought up for the last 20 years on Microsoft Visual Studio so I am used to having a feat...
In this post, I will talk about the building of the hat.To build the hat, I first created a model with a thick sheet of paper. This is easier to cut and to work with. I cut the thick paper with common scissors until I got the desired shape. With...

I started my "career" in electronics not long ago when the first Raspberry PI became available. But looking on the specs I decided that the BeagleBone Black suits my needs better and bought one. What I liked most about it after playing with it for a ...
After their successes with the mechanics and Arduino Yun, Hans and Matilda decided to celebrate with a trip to the local inn, the "Adam and Eve". They walked up to the bar and was greeted by the bartender. Whilst they were being served they noticed a...
Purchased an RGB led strip some time ago, 1m, waterproof, for 3€ from ebay. (Unfortunately, it was not tri-led, so keep that inmind when you purchase)Did a quick test with a multimeter, it pulls around 170ma per channel.The RGB LED Lighting Shi...
Hans was still thinking about the Wolf as he headed into town to get supplies. It was a nice day so he decided to wander down the side of the stream. As he passed the mill he looked up at the water wheel. The stream had been diverted into a wooden ch...
In post 6 I made a breadboard prototype of the speed signal circuit. I made a KiCAD layout and sent my fab files to oshpark.com.My PCBs arrived yesterday. This is the story of the build and test. Let's start with a short recap of the...
I'm currently building the "hardware" of the hat, so before posting a complete update, let's talk a little about the mind of the hat... One of the most common complaints of Arduinos is their lack of connectivity. You build thes...
Over the weekend just gone by I managed to create an Ubuntu boot disk and get the SAMA5D4 running with an operating system that provides me withfeatures I am a little more used to vs the Poky build that Atmel provide. What I built was Ubuntu 14....
I noticed that a couple of us are looking at the weather. I think I can get all I need from the Yahoo service so I'll go with that for the moment.https://developer.yahoo.com/weather/documentation.html Here's a couple of articles on other APIs th...
Whilst Matilda was planning and rebuilding Hans hit the books to study the new electronics they were going to add to their house. Hans was having trouble understanding the Yun parts, "why does it need two processors on one board?" he thought to himse...
The Internet of Things will be built on a base-layer of Internet-connected “Smart Objects”. However, there is a growing discomfort among individual users about being surrounded by Objects that collect information and then send it to who knows where t...
