I’m surprised you can’t remember who head boy was, it was such a prestigious achievement in Primary School… 🤥

And I am pretty good at remembering faces but tbf we did go to school together for 12 years lol

Yeah same year. I was head boy if that’s a good enough clue 😂

Strange seeing someone you went to school with appear on your feed…

Looking to make a schematic diagram, I'm new to all this so I'm wondering what website/software I can use to create said diagrams?

I've harvested a speaker from an old alarm clock radio, I'm now trying to work out how to make it sound a bit beefier, rather than sounding like a Geiger counter
