2 Weeks ago I spoke at a Data Ninjas meet up in Bristol about AI.

Excellent meet up where I met a lot of very nice people.

I just checked on Brew #20 – which went into the fermentation bin on Sunday evening, and it’s bubbling like crazy. 

In other words – it’s all going well! It’s a little bit scary – my wife messaged me earlier today as said that the brew was making whistling noises, and being very active.

I have had one of the new electronic train ticket cards for quite a long time at the moment, but I am unimpressed by some of the system.

Every morning for the last 2 weeks this is what the electronic sensor at my trainstation looks like :

It’s been rebooting for 2 weeks.

On the train the onboard staffs readers seem to be malfunctioning or out of battery more than 50% of the time. Even when they work they take 4 times as long to check as the old fashioned tickets.

Not terribly impressive.

As can be seen from the graph the new thermostat seems to work as it should. And the controlling software (FHEM) now runs off a Raspberry Pi.


The red line is the set point temperature

The violet (?) line is how many percent the radiator actuator is open.

The green line is the room temperature as measured by the thermostat.

Btw. this is from today (Sunday) – and it was down to freezing last night.

As I tried to get into my hotel room on Thursday I was met by this :

It made it slightly difficult – but after a few minutes the driver turned up and let me in to the corridor (-;

Todays brew (#20) was a Single hop Citra from The Home-brew shop.

It all worked out as it should today, with the mashing and boiling perfectly on

OG was also sport on as 1061, with 23L in the fermentation bin for now.
