Image Mosaic QR Codes

Submitted by gerry on Thu, 07/07/2011 - 11:48

One of the guys at tog mentioned in a recent post to the mailing list the idea of using a photo mosaic to make up a QR code, as opposed to the usual black on white that we see everywhere.

To see if it works, I created one, and it appears that it does. Not sure about the thresholds of size and contrast though, as this is just a proof of concept, rather than an exhaustive study.

Open Streetmaps

Open StreetMaps is a worldwide collaborative effort to create a high quality, unencumbered street-level map of the world. When I first came across it, a few years ago, Co. Galway was almost unpopulated (with mapping), and Galway city extended as far as Moneenageesha.

Things have changed, however.

On Marlow's suggestion, I downloaded a daily Garmin build of the Ireland map and installed it to SD card for use on my Nuvi.

Galway has a new HackerSpace.

Going by the name 091labs (from the dialling code for Galway, 091) a HackerSpace has recently become active in Galway in the West of Ireland. I have yet to visit, but am very excited that we finally have our very own HackerSpace...

Best of luck!!

X10 Home Automation with SMS

Submitted by gerry on Wed, 02/10/2010 - 10:57

I am currently building a house, and as such, have a great platform for implementing all the things I have dreamt of but could never manage to achieve in a rented house. Apart from finally having the spaghetti finally embedded in the walls and floors, and having almost enough power and network sockets (you can never actually have enough, right?) I can experiment with centralising control of the house and accessing home telemetry through my phone.

APRS is often misunderstood to mean Automatic Position Reporting System, when, according to creator Bob Bruninga, WB4APR, it actually stands for Automatic Packet Reporting System. Some might maintain that the primary purpose of APRS is vehicle tracking and service position reporting, and, while this is not entirely untrue, it does sell short the possibilities of this excellent technology.
