Thermostat in progress

As a potential upgrade for my Raspberry Pi heating system, I am working on a thermostat module for it - still in the prototype stages, more info to come but here's where we're at now:

eGalax 7" screen raspberry pi with sketch + GUI

I wanted a light installation of raspian, so I got sketch and added appropriate stuff to make x work.

To install GUI
sudo apt-get install xserver-xorg lxde lightdm




This stuff was required to make the touchscreen work - otherwise the calibration just didnt do anything.

sudo apt-get install libx11-dev libxext-dev libxi-dev x11proto-input-dev xserver-xorg-input-evdev xinput-calibrator  evtest -y


cd /usr/share/X11/xorg.conf.d
sudo mv 10-evdev.conf 45-evdev.conf


sudo vi 99-calibration.conf
add xinput_calibrator output, which should look like this:


Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "eGalax Inc. USB TouchController"
        Option  "Calibration"   "67 1948 1877 183"
        Option  "SwapAxes"      "0"

Broken Ribs

Three weeks ago today I had a kite-surfing accident and broke/fractured rib(s). At the time it was uncomfortable, but I carried on surfing for a few minutes, and it was time to pack up anyway.

I was able to pack up, get home, unpack the car, get out of my wet-suit etc, all a little uncomfortable, but really not too painful. The next morning I went to drive to work, and I got about 100 yards in the car and the clicking and pain was almost unbearable. It still makes me a bit light-headed to think about it.

I limped home, and ended up at home for 3 weeks.

The first week I really did no activities at all. I wasn't away from the house for the first week.

I got some stronger painkillers on prescription, and began taking them immediately. I struggled to do basic things like getting up the stairs, or standing and sitting. All week I lay exactly flat on my back all night without moving. Very uncomfortable.

By the time one week had passed, I was able to be a passenger in a car. I was able to get in and out of a car with a bit of care. However, at this stage I was struggling to get in and out of bed, I made sure I only made the transition from horizontal to vertical once per day. No laying about on the sofa, I only spent time sitting straight up during the day.

After about 10 days I tried driving a short distance, but it was still very uncomfortable, so I gave up driving for that second weekend. Each day I felt more comfortable, and at this stage I was able to sleep a bit on my side; my good side only, not the injured side.

Today, 3 weeks after my injury I returned to work. I'm still clicking a bit, and to be honest, driving is probably the activity I find most difficult. I'm much more comfortable sleeping, in fact last night was the first night I got to sleep on my injured side.

I still have some way to go, but I'm feeling incredibly better than I was, and each day brings an improvement. It wont be long before I'm strapped to a kite again ;)

Kitesurfing - Downhill - 11th September 2017

Epic conditions tonight at Downhill, nice wind for my new 9 and the longest flats between the waves I've ever seen. Out after work, on the water for about 90 minutes.

Then I tried a down loop waterstart. Epic fail, crashed kite and face plant. Sore, but quickly recovered. Then I tried a back roll, and I really have no idea what happened, but I fell hard on my left side.  Real hard. So hard in fact that I think I have broken more than one rib. They are cracking and popping like mad. 

I suspect I'll be out of the water for a week or two :(

Kitesurfing Benone 9th September 2017

Today was forecast to be good north west all day, but better in the afternoon with more sunshine. I went to Benone after lunchtime and there were 4 other kite surfers already setting up. They were strangers to me, seemed nice, and also mostly learners, I think.

I set up and set off, but it quickly became apparent that these guys were in my way. Being learners their kites were almost always at 12 o clock and I was upwind of them, meaning I couldn't easily sail past them. The wind was quite onshore too.

So I packed off down the beach, downwind of them. It was great. Great conditions, and the new kites boost a lot more than the old ones. Really enjoying them. I was there for a few hours, just getting to grips with the new kite, and how quick it is compared to my old ones. Great Saturday afternoon!!

Kitesurfing - Benone - Friday 8th September 2017

Forecast looked good for this evening all week, and it actually happened. I don't think I have been this nervous about kitesurfing for ages, taking to the water on a new kite, and not knowing its characteristics.

Anyway, after work I headed straight to the beach, someone else wa kiting, so I went to near them. I took a lot longer than normal to get set up, as I was making sure everything was ok with the gear.

It was quite showery, but between the showers I had a great wee session. This is the first time I easily stayed upwind in a long time. Totally juiced on the new 9.

Kite 5th September

Tonight I went to the beach to try out my new kites. They arrived in the post today, two Ozone C4 kites, 9 and 12.

I was really only hoping to set them up and see what they flew like, but unfortunately there really wasn't enough wind to even do that. Maybe another day.
