V = IR. It does.
So does P = VI. Yup.
I learned this in 4th form physics, along with the bit where everything is made up of electrons and stuff whizzing around, and all my perceptions of the world were actually wrong. The bit about the electrons I never forgot, but my need for V=IR ended with my need to pass bursary physics. I haven't used it since, not even for electric fencing. Electric fencing, you see, is designed to be idiot proof, and as long as your unit is putting out X voltage (normally ~3000-5000) and you don't get a current reading off your tester, it's all good. If you get a current you find the fault and fix it. Voila! No need whatsoever for formulae.
So when I decided to muck about with electronics because I had a shiny brainfart, I was immediately faced with the level of my own ignorance.
Embarrassing enough so I emailed grist and said "Explain please!" And he did, and it was awesome. But like all things I do which are generally orders of magnitude more ambitious than my level of skill when I start, the answers just raised more questions, and now we're planning a face to face meeting where handwaving can be incorporated, and I should probably take a notebook.
What would be better would be to set up a lab. Not a mad science lab, but a lab in the sense of 'doing stuff in a practical way in order to learn'. Because I'm a kinaesthetic learner for the most part (much like many people), and the way I cement things in my memory is to apply them. I've learned over the last little while that talking about things works as well - as most of my friends would attest, having had their ears bent about pretty much everything I learned as part of my degree.
But I don't want to talk too much about this particular brainfart because a) I'll be going over a lot of ground that everyone else has already covered, b) I don't want to be a tech bore, and c) I am afraid of failure. What if it turns out I truly am crap at this stuff, and I spend ages learning new skills only to end up with something your average primary school kid could produce?
This is not a cue for people to jump in and reassure me that I'm spectacularly clever and couldn't possibly fail, by the way. It's an admission that I really don't know what I'm doing and all I have is a vision, and the gap between my knowledge and my vision is kind of daunting.
But I've never let that stop me in the past, right? And it won't this time, but I'm not going to be all "And then I'll do this, and that, and it'll have a thing that does X, with Y and Z as potentials if that turns out OK, and I think we also need a quadcopter, because quadcopter!"
Anyway, V = IR and P = VI. It's a start.
See what happens when I don't have to write essays every 5 minutes?
Meanwhile, my sore throat from yesterday is the same today. No other symptoms, just a pain in the right side of my throat around the adam's apple/tonsil area that makes it hard to swallow. And associated dreams about being attacked by zombies. In my dreams, even animals can be zombies.
Much better was the dream where Dr Wheel was leading shirtless street yoga, doing fantastic bridge-to-handstand moves, all finishing with a Bollywood style synchronised yoga parade of about 200 hot people. Now we're talking. Fuck off, zombies. Bring on the yoga.
Finally, we have Surprise!Soundsystem. Well, not a complete surprise, we did want one, but one turned up suddenly over the weekend and we got it and Dr Wheel set it up last night and Mmmmm nice sounds incoming. I promise not to sing along out of tune at the top of my voice like our neighbour does.
