As part of my home monitoring system I needed a display that I can use at different places in the house, preferably without a full computer attached.

And ideally I should not need Ethernet cables run around the whole house, so I decided to use a Jeenode to supply the intelligence, with a LCD display attached using one of the Jeenode LCD-adapters.

So I knocked up some code on one of my Jeenodes to do the display part, and some code (in Ruby) on one of the Mac's - and this is the end result :

Getting a LCD display working with a Jeenode is easiest done using a LCD plug - but it took me much longer to get it working than I had expected.

And it all turned out to be a stupid mistake on my side :

If you can see the small potentiometer (on the top right hand side of the main chip) - it's really difficult to turn, and it controls the contrast. It turned out that it had not moved when I put a screwdriver in and turned it...

At the start I did not solder the correct 3 bridges on the card either....so lessons learnt and so on.

For years I've used a set of ER6 earphones from Etymotic, and overall been reasonably satisfied.

On the negative side it's very hard to get a good enough fit to get decent bass from the earphones.

On the positive side the mechanical noise reduction (by getting them inserted properly into the ear) is fantastic, your fellow passengers on the train or plane can't hear what you are listening too - nor are you disturbed by them.

So this time around I went for the new Etymotic HF2 - with a twist, as I now have the option to get a set of custom earbuds made in Guildford (!) to get a perfect fit. But the earbuds cost the same as the HF2's - turning them into a set of very expensive earphones indeed.

This is a particularily interesting lightsensor - as is reacts to the same range of light as the human eye - and additionally uses a I2C bus that makes interfacing it to a Arduino or a Jeeduino. Indeed the Jeeduino is getting a "shield" that works with this sensor:
