We now have a (rather good) LAN on our boat – but the last challenge is to access the computers on the boat.


4G networks do not generally hand out a IP address per endpoint, not even a dynamic IP address. So other means need to be used, and I stumbled across, which has a free service for single endpoint use.

And they supply their own management apps for MacOS and IOS etc., or you can use other protocols (including VNC) to access the Raspberry pi.


I have just installed it, and will move the Raspberry Pi to the boat this weekend. As a matter of fact I will move 2 Raspberry Pis there, one to be a Plex/Kodi server, and one to manage our power devices – as we supply power from batteries/solar panels/generators/engine/shore, and it all needs monitoring to ensure it works correctly.

This is really interesting



Some photos of the BBQ automation hardware


First the fan/blower that will be attached to the air inlet of the barbecue



Then the electronics assembly – it’s really a combined micro controller and a Raspberry Pi.

The Raspberry Pi runs the web server and UI, the micro controller does all the real work.


This is a close up picture of our new sprinkler (irrigation) computer controller.

It’s a Raspberry PI with a PiFace board and a extra board with 2 relays. So it’s effectively a 4 channel relay based controller, using Domoticz software to control the sprinkler valves.


At long last a case for the Raspberry Pi with a piTFT screen that you can actually make look neat. From LadyAda of course.



It turns out to be fairly easy to get a Raspberry piTFT to show the desktop during after booting if you follow the instructions here :

A garden irrigation management kit based on a Raspberry Pi and a standard PiFace interface card

After the tutorial series, I’m please to announce the first official Irrigation System WebIOPi-based application. It can work with PiFace, IO PI, or any I/O expander supported by WebIOPi.

The system provides both manual and automatic mode, with a week schedule to activate each station in sequence for a given duration. Even for people who don’t have an irrigation system, it’s a very nice application to go more further with WebIOPi. On my side, it pointed me few issues and difficulties can encounter people when using the framework, so I can improve it.

My LED clock is taking shape – as you can see in the picture (even though a quarter segment of the LED ring is missing).

It’s now running off a Raspberry Pi connected to a FadeCandy module via USB – then on to the NeoPixel ring.

The red pixel shows seconds, the single green LED is indicating minute, and the 5 blue LED’s indicates hour.

This is typical misunderstanding of iBeacon.

Virgin Atlantic airlines is now rolling out a pilot program for Bluetooth-based iBeacons to be stationed throughout Heathrow Airport’s Terminal 3, in an effort to “provide a greater customer experience” for travellers, the airline said. The proximity-based technology, which can send push notifications to those who permit it as information becomes relevant, can alert users of facilities in the lounge, pull up boarding passes as flyers approach the gates, or update flight status.

Just to set the story straight – iBeacons only broadcast a ID message – and nothing else to the users phone, it is up to the software on the phone to do any triggering, reception of messages etc. The iBeacon is incredibly simple – so simple that it only took me a few minutes to set one up on one of our Raspberry Pi’s.
