Ohai ignorance, I see you're still hanging around - Tactical Ninja

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.


It's embarrassing.

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!"

You know?

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.

Seems a few people around here are struggling with low energy right now.

I blame February.

oh yay .. seasonal changes... >.< but maybe also i need to set up a solid study area in my room, *frowns a little* need a little desk, one that fits down the stair well *ponders this to* might have to have a fossic about and things with stuff...

and lots of naps...*grins*

I have been trying to find a pic of that for comparison but I don't have one on this machine.

That book I mentioned goes over everything from the basics, it doesn't assume much theory at all, and only teaches what's necessary to understand how the projects work.

That's the one that covers the arduino stuff right? That will definitely be my next port of call, once I have my head around basic electronics.

Yup - and what I'm trying to say but clearly failing is that it covers basic electronics. Which of course doesn't mean it's not worth talking to people too.

Ah right. I will bump it up the list of things to look at then. Thank you.

I am Electric Circuit of Borg. Resistance is futile. :)

So basically, you've identified a gap in your knowledge, and now you're planning to learn New Stuff to fill that gap? That can only be a good thing. After all, it's not like you'll fail to learn.

Not really, but the pain and swelling is more where my larynx is, which is just out of view. I can feel it from the outside, it's puffy and tender. Weird. I suspect a localised infection of some kind.

Dunno. My voice is fine, I did training alright today, everything seems normal except for the hurty lump.

So I'm going to pretend it's not there and carry on. ;-)

hmm.. i figure give it 10 days from when the hurty was apparent.. and if still hurty, or not any better go to doctor?

in the mean time to help it along.. i suggest gargle, warm salt water.. aka 1/4 teaspoon salt with 1 cup warm boiled water.. *nods* which can help draw any hurty out..

*adjusts nurses hat*

I think I similarly get an idea and then go figure it out / learn about it. thing is, once I've learned enough to realise I could do it I then often get bored and go find something else to pick up... before actually finishing the thing or refining it beyond "decently functional prototype".

One standout different project owld have to be the mower sound system: today I picked up plastic tubing for housing the underbody LEDs that some twit ripped off. Possibly me.

Boredom might come from so many people at Kiwiburn going "oh my god why didn;t I think of that?" and a possibly resultant slew of mower stereos coming out.

None of course will be as good as the original.

My lab is my garage!

I think next year's KB theme should be "MOWERMANIA".

"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?"

Then you will have followed passion outside of your comfort zone, developed a new skill and the have the pleasure/satisfaction of producing a thing from scratch. I'm not rating your quality as a person on your success at electronics any more than you are rating mine on my academic publication record or the number of new hoop tricks I master this year. Deal?

I try to do it at least once a year. It's good for my humility.

Watch out, it's contagious. We might start an epidemic of exploration and skill development.

I had a dream last night that I moved back into my house in Wellington, built out the attic into a quirky master suite as I've long fantasized, and Air BnB'd the existing master bedroom. It was good, and subsidized my life for all the other awesome stuff I want to do.

Not sure if it was dreaming or offline processing of this windfall dilemma.

I didn't realise your attic was big enough to consider doing that with!

That's an open question that requires a more expert opinion than I'm capable of. I think with a shed dormer off the south side and some skylights, it might be funky and interesting in a low-ceilinged, strangely-shaped way.
