Kitchen Window Sash In

As I hoped, I got the kitchen window sash in today. It's big.

More Windows

I ruined the first attempted window for the south side of the main bedroom on June 15th. After that I was fairly depressed for about three weeks. Losing the not-entirely-cheap window was a bit of a setback but I was more bothered that the windows had already taken long enough so far but I thought I'd at least got fitting them sorted but apparently not and I wasn't really sure where it had gone wrong - whether I'd bent the hinge moving the sash around before trying to put it up or somehow while lifting it. Getting out of that state wasn't helped by not sleeping well for various reasons including hiccups and a bad back.

Since then I've got the bathroom window and the replacement for the damaged main bedroom window in and the remaining three windows to hand with the kitchen window sash ready to be installed on the next nice day, tomorrow I hope.

Web Key Directory Implementation

Programming the Sonoff TH16 version 2.1

Sonoff make a range of Wi-Fi-connected devices for various monitoring and switching applications based around ESP8266 processors. As I wasn't happy with the performance of the thermostat in the fridge in the house I'm renting I got a few of their TH16 switches with the idea of using one of them to switch the fridge on and off without freezing the food in the salad compartment.

A few sources indicate that supplying power to these devices while flashing programs in them is tricky. tl;dr, I found that a surprisingly high voltage, about 3.9 volts or higher, was needed to load software in the version 2.1 devices I received. I'll explain the process by which I got to this conclusion in some detail as there may be some useful hints for others along the way.

Ruined Window

June was not too much of a success. I finished off the window in the small bedroom which I got in at the end of May but then had problems doing the similar one in the main bedroom resulting in a window with enough damage that it'll be better just to get a new one.

Using Clamps To Separate Scaffold Bits

Most people are familiar with the sort of clamps used for wood but some might not be aware that, as well as being used to clamp things together, they can also be used as spreaders to push things apart.

Window Sash In

Today turned out to be mostly dry with a bit of breeze from the north so I tried out my cunning plan to lift the small bedroom window sash into place. It turned out to be cunning enough, just.

A Little Window Progress

It's a wet and breezy Sunday morning nearly three months after I last posted so time for an update even though there's not a huge amount of interest to report. tl;dr I'm ready to put some more windows in but haven't actually done any yet.
