Happy New Year

Just about to set off on what is set to be a mammoth night with the Kool Kids Klub @ the Sunrooms: https://www.facebook.com/events/295464730481459/

Been busy today:

Setting up the new D-Link switch DGS-1224TP: Well impressed with how it compares to the old Cisco / Linksys SGE2000P.

D-Link / Linksys
Weight: 3.4 Kg / 5.8 Kg
Power Consumption (idle): 24 W / 42 W
Depth: 21 cm / 37.5 cm

I think it’s quieter too but don’t have a way of measuring it!

Installing the new RAM in the file servers: both the HP Microservers (running WHS2011 and FreeNAS 8) now have the maximum 8 GB RAM.

Finishing my first iPhone app: It’s not pretty and it certainly won’t be submitted to the app store, but it serves a purpose!

Currently I have a handful of devices on my A/V cabinet in the living room all of which can be controlled with apps on my iPhone. Unfortunately the HDMI matrix which sends the signals around the house doesn’t have a remote app… it does now :)

Still tons to do… I really need to do all the structured cabling and mount the comms cabinet with the new switch before going back to the office next week but that’s somewhat optimistic.

Happy New Year!

A few small updates

A few small updates as I have a ton of projects on the go at the moment.

FreeNas 8

After a friend visited earlier in the week I decided to give FreeNas / ZFS another shot- so I’ve installed the latest v8 on a spare HP Microserver N36L. The little cube has 4x 1.5TB Samsung disks in RAID-Z with a single 4GB stick of RAM. I have ordered another stick of RAM and a low profile, dual-port, gigabit pci-e network interface card (nic)- the HP NC360T (intel chipset) so I can setup load-balancing/link aggregation/LACP. I starting copying some data off of the current production Microserver (WHS2011):

Performance seems average. I’d expect to see a bit of an improvement when the gigabit HP / Intel nics arrive.

New Orders :)

I have put my Cisco SGE2000P 24-Port Gigabit managed PoE switch up on eBay as it’s a bit too big and loud for the small data/comms cabinet I bought recently. As a replacement I have ordered the D-Link DGS-1224TP which appears to offer the same feature set at half the size and half the weight (I think it may also be passively cooled and is touted as being "green" so hopefully help with the leccy bill :)

I also have a few Sonos S5 network wireless hifis on order (they were on special offer and I’ve been looking at whole house / multi-room audio distribution solutions for a while). I have a slight concern I may need to buy some Apple AirPort Express access points to enable AirPlay on them but I’ll cross that bridge as/when…

Apple Programming

I’m learning xcode / cocoa / objective-c / osx / iOS whatever they call it as I want to write a little app to control my 4×4 HDMI matrix. The device is on the network and supports simple commands using a telnet style socket connection, so I’m hoping it won’t be too tricky! Unfortunately I couldn’t find the old control software I had or documentation but eventually stumbled upon the pdf with a few pointers. So the reading begins… http://developer.apple.com/library/mac/#referencelibrary/GettingStarted/Learning_Objective-C_A_Primer/_index.html#//apple_ref/doc/uid/TP40007594

A few photos :)

I’ve not been out much with the camera lately but a few from the usual monthly residency @ the Kool Kids Klub:

I hope you’ve all had a great christmas!

The last 24 years at the tap end for 2011… a reading from Chris Stark’s autobography:

More Tap End :)

Not only a new instalment, but also one I was missing from the collection! More 24 years at the tap end- a reading from Chris Stark’s autobography:

The previous 9 can be found here: https://tickett.wordpress.com/2011/12/09/24-years-at-the-tap-end/

Enjoy!

Just logged in to see a few improvements / updates to the http://my.currentcost.com dashboard. Compare daily usage for week periods:

Record gas & water consumption (not tried these yet):

And finally- record consumption cost (to the nearest penny isn’t going to give very accurate cost estimates but it helps):

Meanwhile Enio (http://www.enio.co.uk) has now been down for over a week.

The latest installment from Friday’s show. I’ve now set Sky to record the Scott Mills show every day so I should be able to catch all of Chris’ readings from his autobography even when they’re not included in the Scott Mills daily podcast.

More Home Automation Chat

I’m away from home at the moment so not much to report. I’ve not had a chance to install the water meters with my friend yet nor connect the gas meter to the hah but I have taken delivery of a bunch more jeenodes and room plugs:

Starting to put one together:

I now have 3 nodes collection temperature, light and humidity data and posting to pachube along with my total household power consumption and appliance level detail for 6 devices:

Whole house power consumption:

An example of individual device consumption (this happens to be the boiler):

Room data:

I’ve tried to create a "naming convention" where the data stream id contains the nodeid (first digit) followed by 1 for temperature, 2 for light and 3 for humidy.

You can quite clearly see where the temperature rises in line with the boiler coming on. You can also see the light pattern during the day (wow- it’s getting dark real early!!!). Humidity isn’t really of much interest.

Interestingly I think node 2 is in the same room as the receiver/hahcentral/hub but seems to drop out every few hours. Node 3 in the room next door is rock solid. And node 5 in the room next to that is extremely flakey! Brett from over at hah has suggested lengthening the antenna on the nodes to resolve these issues- I will do some experiments when I have a little more time on my hands :)

And one final note- whilst on the topic of "home automation". I have replaced my sky boxes in recent months with the Clarke Tech ET9000: https://tickett.wordpress.com/2011/09/20/getting-started-with-clarke-tech-xtrend-et9000-and-sky-hd-uk/ and pipe the picture round the house from these and my home theatre pc (htpc) running xbmc with a cheap 4×4 HDMI matrix I picked up off eBay. I now have full control over these devices from my mobile phone (iPhone):

DreaMote Lite (for Enigma2 satellite receivers):

And XBMoteC (for XBMC):

All slow, but steady progress toward a completely integrated/automated home!

Evidently not all readings from this legendary autobography are making it into the Scott Mills daily but each and every one which does I will be uploading :) I’ve added today’s instalment available for download: https://tickett.wordpress.com/2011/12/09/24-years-at-the-tap-end/

Enjoy!
