In 1671 apparently not a lot happened in England. Parliament moaned about the rise of Roman Catholicism and someone called Blood tried to steal the Crown Jewels. Around the world I’m sure there was plenty going on but there’s not a lot on Wikipedia. The pope made someone a saint – whatever that really means – and the Ottoman Empire declared war on Poland.

A while back I wrote about connecting my lounge room to the router/modem using an ethernet cable. This was relatively easy as I already had a hole in the wall and the distance wasn’t too bad.

I have a Raspberry Pi in the loft acting as an ADS-B decoder for an aircraft position aggregator site called 360 Radar. For some reason whenever the router reset or rebooted the Pi wouldn’t connect straight away to the wireless network and I had to reboot the Pi as well. This wasn’t bad but mildly irritating. So, after mentioning it at work it was suggested that I hard wire the network in using Ethernet Over Power, which I was, then, already using to keep the entertainment centre wired rather than wireless.

Now, EoP makes a lot of sense. You already have a network of wires in the house and so just adding a high frequency signal into them is easy and won’t affect anything else. How far these signals travel down my street I don’t know. I’d be tempted to plug one in next door and see if I can get a signal there. I have encrypted my signal because I’m not stupid. TP have a utility so you can manage the EoP modules from the PC and I have used it to see what bandwidth I am getting.

Ethernet Over Powerline
Ethernet Over Powerline

As you can see I should be capable of getting 600Mbps over this connection but some things are working against me. The instructions say that these shouldn’t be plugged into extension leads and definitely not multi-gang extensions. Both of them are sorted like that. Who else has that many plug sockets near the IT centre of their house? These aren’t even pass-through modules so that can’t work. To be honest I’m happy with 200Mbps. My internet connection is only 70Mbps and so the EoP can easily handle that. Not that it needs to!

My router/modem has currently an uptime of just over 18 days. In that time the Pi has downloaded 194MB but uploaded 8GB. That’s not a lot really for that length of time.

18 Day Totals are:

  • Pi ADS-B – down 194MB, up 8GB
  • PC – down 900GB, up 66GB
  • PS4 – down 225GB, up 11GB
  • Shield Pro – down 1TB, up 25GB
  • My phone – down 344GB, up 80GB

The other devices aren’t interesting and don’t do as much. The bandwidth of the Ethernet over Power is perfectly suitable for its usage.

Screen Capture

Downloaded an app to the iPhone that controls my tv via the home network. All very well and good but there is also a screen capture button! Why? Who would need to screen capture a tv? Apart from writing this communication that is?



Simulview and Dual Play

Simulview is Sony’s buzzword for displaying two player images on a 3D television so that each player sees only their screen. Essentially the shutters on the active glasses activate at the same time rather than alternately and so P1 sees only his/her image and P2 sees their image only. This is quite cool and displays (I assume) a 1080p picture to each player.
Downside: This only works on the Playstation Monitor.

DualPlay is the technology that LG have introduced to try and allow two players to see their own picture full screen. It has taken me four days to figure out how to get this to work (which is slightly embarrassing). DualPlay uses passive glasses with P1 having a left/left combination and P2 having a right/right combination. The standard two player screen (up/down or left/right split) is then stretched over the whole screen. This will work with most games with that picture split.
Downside: Aspect ratio issues.

 I haven’t yet tried this on my TV but will soon. I am quite excited about it but also worried about the aspect ratio change. Nice of LG to think of gamers though.

I’ve Seen The Future

Ok, now these are impressive. I was at the Kiddicare store in Thurrock, Essex and I noticed that the shelf tags looked quite a bit different to the card barcode things you normally get in a superstore or shop.
I looked a bit closer at these tags and was pretty sure they were LCD displays with some sort of stock count thing going on. While closely inspecting a shelf tag a store worker came along with a bar-code reader device and so I asked if the tags were LCD.


I also asked if they were radio controlled with real time stock updates.

YES! The stock tags update every five minutes.

I was so impressed with this use of tech that I nearly forgot what I went into the shop to buy. I have seen the future, and it will be.
