Managing wired and wireless networks at Bristol University. I also enjoy brewing beer, messing with my Solar and watching Bath Rugby 🔵⚫⚪ Opinions are my own.
The first of two new chapters starts today as our eldest has just been dropped off at @bristoluni.bsky.social Luckily she's only an hour or so away. Missing her already.

This is such a good video - by the way, the only car I have is a petrol Ford Focus...

@octopus.energy I sent an email a couple of days ago because, since switching to Outgoing Octopus on 23rd April, I'm not seeing any solar export credit to my account. I've not yet had a response but hopefully someone can look into this for me?

Due to circumstances beyond my control it's rare I have good days at work recently. Today was one of them. I've been working on #wifi design processes in a complex environment. I love working on things I actually understand and I'm good at.

Another #solar personal best - 45.2kWh. I guess there will be many more until Midsomer's day...

First attempt at a diagram of the components in my #Solar System and what protocols they all use. Is it any wonder the integrations between these systems are terrible and full monitoring/control is near impossible? Note that everything relies on access to proprietary servers!

@octopus.energy Hi my tentacled friends. I'm trying to switch to Octopus Outgoing but it seems stuck half way through the process. I have a support ticket in but not had a recent update. Anything you can do to push things along?

Another record day on my upgraded solar system. 40.6kWh. Today should be even better.

I'm currently off-gas and heating water with excess solar (i.e. diverting anything above 3.5kW using the Eddi).

Happy 2nd birthday to my solar system. Just over 8MWh of energy produced which apparently equates to:
- 4.45 trees planted.
- 8 tons of CO2 saved.
- 3.21 tons of coal.
Not sure how you plant 0.45 trees though 😉

Cracking solar day today 🌞 It's a record breaker for my upgraded system.

#WiFiDesignDay kicks off.
April 3, 2025 at 9:08 AM
I'm really looking forward to #WiFiDesignDay in London in a couple of weeks time. It's nice to catch up with some top people. Here's a boring photo from last year... Need to take better ones this year!

A perfect day of solar generation and more to come this week 🌞

Very different weather on this day last year...

Fascinating article on how the Estonian, Latvian and Lithuanian power grids are disconnecting from Russia and connecting to mainland Europe this weekend.

Is MS-DOS still at 0.2% in 2024? Wow!

I'm not going to tell you how many systems I've used over the years. That'll give my age away!

Just doing a bit of CWICP studying and this video on IQ signals, and how it's used to generate QPSK, was recommended viewing. Brings back memories of my degree - but probably better explained!

@bathsupporters.bsky.social I see the England 6 Nations ballot for STHs is out. Are you aware of how to get tickets for the Wales v England game?

Why are households not getting paid more to save electricity during DFS events?

Well, that's Facebook and Instagram now permanently deleted. These platforms should be getting better, not worse.
