[Happy] Achievements of the week..

I have been a bit busy of late so not recording things that have been making me happy.. but as I come to the end of the week it is worth me remembering that within the busy I have been awesome.*

1) I managed to high five a chap who was waving for a bus as I cycled past.  

2) I worked out a way with the technology available to live stream H as she taught a crochet class, do that we can have a close up of her hands as she demonstrates.  This close up is then displayed on the big screen so everyone can see.

3) I have successfully covered for my boss while he has been in holiday for the last fortnight.  I have finished this week with 350 unread emails, and 130 flagged for follow up.  However the sky hasn’t fallen and I have stepped up and presented myself well.  Even if I was starting to look a little tired on Friday.

Right now to try and relax a little.

* Even if I do say so myself.

[Tech] Not what I expected to come out of his toolbox..

I have just had a very nice man fix my boiler* with a bicycle pump.

No really, the expansion vessel had lost pressure which was causing the pressure release valve to empty the heating system into my back garden.
The fix to this is to repressurize the expansion vessel with a bicycle pump.

As a geek, this is somewhat disappointing, as I could have done that.. if I had known.  Ok I didn’t know, and while I did do some research on the web that was one of a few potential solutions so it was best for me to hire someone who has had the required training.

* No he wasn’t from the AA but Centrona Gas Services.. **
** This isn’t much of a plug, more so I remember them for next time..

[tech] this was posted from a Windows free laptop..

So after 2 weeks of faffing I now have Debian running on my laptop, took rather more mucking about than it should have done.  Just so I remember what I had to do here are some notes.

To get past UEFI secure boot I had to install Ubuntu, once that had successfully installed the grub boot loader, then I could install Debian non-free as the USB wifi dongle I was using was based on the Ralnk chipset, and that isn’t part of the standard package.

Once that was installed, you could add the distributions for back port and  contrib and non-free to /etc/apt/sources.list also add support for 32 bit architecture and install  firmware-iwlwifi

After all of that it seems to be working, which is a very good thing.

[Tech] Phillips Hue – First thoughts

So a few days ago I picked up a set of Phillips Hue lightbulbs to review.  I had heard really good things about both the colours and the user interface.

Packaging:

The packaging is really smart and integrates a very neat colour wheel, which is a very nice fun touch.   You feel that someone has cared which helps with the buying experience,  as they are really quite expensive.

Installation:

The bulbs are Eddison Screw,  so in the UK you will either have to buy adapters, or rewire the standard bayonet fittings.  I had one Ikea lamp that took E27 bulbs,  so that was easy, and as I’m a practical boy bought some new drop fittings for my existing pendant light fittings.

Now I can’t blame Phillips for this, but the only ones I could find where black, even the mighty ScrewFix do not stock E27 pendant fittings, so you may have to hunt around.  Additionally these have a greater diameter than BC fittings so my lampshades now don’t fit.   This was a frustrating that I wasn’t expecting.

Connecting the bridge was easy,  that requires a physical network connection to your broadband hub and a power lead.   This can be wall mounted, but the cables connect to the base of this unit, so this as missed an opportunity to be as elegant as the bulbs.

First Use:

With the bulbs installed, they will work as regular lightbulbs, switching on and off on the normal switch.  Switching them on in this way they look and act like standard bulbs.  Which is good.

With the app downloaded to my phone, this is linked to the bridge with a very simple pairing process.   Then the fun can begin,  or actually it can’t.

The first 2 features that I was looking for in the app were:

  • A colour wheel,  so you can play at changing the colour of the bulb.
  • A party mode that just randomly changes colour,  bonus points if it reacts to music.

Neither of these exist in the standard app.   You set the colour of the lamps by setting up Scenes or Light Recipes.  Several are included by default, with a simple click all the bulbs smoothly transition between the colours.   Creating a Scene is easy, you select a photograph from your phone add it to the app and then select the colours from that photograph that you wish each bulb to emulate.  You can also set which bulbs Scenes will use,  so if the bulbs are in different rooms then your not randomly turning on a bedroom light at the same time as the sitting room.Scenes define the colour and the bulbs to be used, I was expecting to be able to select a colour / mood and then send that to a set of bulbs, or room.   The default scenes are all called relax / skiing,  the ones I have created have names like “Bed Reading” or it would do if you were not restricted to 8 characters.

My other frustration is the alarm function,  this will only repeat for at the same time every day.   So you can’t set a later wakeup time for the weekends.   Additionally while there is a fade option, this doesn’t simulate sunrise as I first suspected, but is an auto off timer.

Summary:

So I have some frustrations with the Phillips Hue system during my first interactions.  However the bulbs are very good, the light and colours are amazing, and Phillips have opened up the API, so it is compatible with IFTTT and other 3rd party apps.  This I think is were they will prove to be vastly superior to other colour changing bulbs that are on the market.  I will report back with how I get on with actually living with this product before I give a final verdict.

Edit: I was wrong, you can set alarms to repeat on a given week day, which is a very good thing. The flip side to that is of the 3 alarms I have set none of them have worked as expected. Will post a follow up as I learn more.

[Tech] backup compete, now what..

So I have now completed the recovery of my old laptop harddrive.  Which took a while.

That was achieved by the manic words:
rsync -avz /home/russ user@backuphost:/backup/

The lack of a / after russ means that it also creates a russ directory.

Setting up rsnapshot would have been cooler, but not necessary in this instance.
Will have to make sure that I set that up on the next one. Or set up rsync to run on logoff.
