Had by Pi Zero since December, looks nice size, works well until... I tried to power it from powered USB hub. Now it's only good for nothing abstract art!! Or a coffee warmer as gets pretty hot when powered now.

I know, more pallet furniture... but very pleased with my creation

Its not the internet of things as such that excites me; in fact it worries me more regarding security; its the services that can be offered on top of data.

This is a new wave of service creation, condition monitoring, remote technical assistance for home technology, tracking ...

... But all of this can only be possible if we understand the data itself and for that we need metadata. And to make the services suit many data sources we need strong standards for this metadata.

Bed time reading at the moment is OPC UA as an attempt to understand one avenue for this.

RetroPie: Build a retro gaming arcade console with Raspberry Pi #piday #raspberrypi @Raspberry_Pi
http://www.adafruit.com/blog/2014/12/26/retropie-build-a-retro-gaming-arcade-console-with-raspberry-pi-piday-raspberrypi-raspberry_pi/

This is not a piece of art, even not an invention, but a pretext to play a lot with electronics, programming, and laser cutting of course!

This work is based on the work of petRockBlock exposed on his blog.

The idea is to use a Raspberry Pi for emulating old arcade cabinet games – do you remember “Insert coins”? – but with some constraints:

all components assembled in a single and portable box (ok, only a power cord)
easy to use (a child can do it – and he will!), just a push-button for turning on and off
the minimum required to play: 3 action buttons and a joystick
only antiques from the 80s, no more

My 2015 CPD (continual Professional Development) activities.

In 2015 I'm looking forward to playing with the Microchip Harmony framework to product some IoT aware sensors; PIC32, WiFi, 802.15.4, temperature, room occupancy, power.

I'd like to play with the various IoT platforms to discover the positives and negatives of the technology. Looking at the challenge of data movement, scale and storage.

Recently I have been playing with SciPy for measurement visualisations; a great tool that I'd like to more comfortable with.

With an Internet of Things home using a wireless PIR sensor network in your home it would be possible to model room occupancy times and durations. This model could be used to assist a home owner (or automatically) tune the heating controls of the house. This is simple to add to any home with the use of Honeywell's wireless digital TRVs and controller. Such a model can adapt to the homes changing usage pattern keeping energy consumption used for heating to an optimal low.

This is something I hoped to try out using my own sensor network and manual tuning of traditional TRVs in my home but having seen these products tat seems rather old hat!!

Any nice people at +Honeywell able to provide some sample TRVs and PIRs for this experiment??

Engineers solve problems every day... sometimes we create those problems in the first place. Eventually we get it working and tested and then ship the product. What next?

Recording lessons learnt in that phase at the end or as you go is recognised good practice. I am an embedded software engineer and see many different projects with the same recurring problems during development.

I'm interested to here how you document lessons learnt and make them available for others to learn from. #software #embedded #lesson

Paging Mr. Spock: your tricorder has arrived

The Arducorder Mini, an Arduino-compatible pocket-sized handheld sensing tool and the next in line of open source science tricorder-like devices designed by Dr. Peter Jansen, is nearing completion.
