i wish i had done anything at all with that electronics knowledge instead of just following the instructions to build the projects when i was like 8, then packing it away and playing video games til i forgot all that poo poo entirely replace "radio shack electronics kit" with "college" and you have the past couple years of my life. oops

btw this is the best space book you can buy an 8yo doesn't matter that the words are way beyond an 8yo's reading level, the illustrations are incredible

thinking of doing a "200 in 200" video where i buy my old lab kit, shoot a 3h20minute video and try to get the whole book done, 200 projects in 200 minutes the early circuits should take 5-10 seconds each, but i'll need that time for the later ones.

that's not a v. helpful toolbox when you need to actually get poo poo done  i have no idea how to search for the electronics kit i had as a kid but it was gray and yellow and besides the spring terminals it had these teeny little breadboards like 5x3 all over the place so you could make little patches of multiple wires without the other ones springing out. totally sick i learned electronics at a science summer camp i went to every year. it was taught by this red haired chubby guy with a temper. he made everyone start out with a real breadboard and a bunch of tacks before he'd let you solder or use one of the fancy new plastic "modular breadboards" (oooooh)

I love analogies except when I'm in church I have this theory that people leave church feeling like they've learnt something but it's only because they identify with the analogy, even if the original concept was completely nonsensical

i love breadboarding it's an unabashed love that belongs on the autism spectrum, neatly putting my wires in exactly the right place, arranging components, the pleasure of a circuit working correctly the first time if it doesn't work there is the unalloyed joy of a circuit with all its bits laid out so getting an o-scope on it is n.b.d win/win

its really entertaining how troubleshooting a tiny little circuit board can make it explode into this fuckin six foot wide wire/tentacle demon from hell that is carefully spread over the kitchen table including this one weird wire that has to hang over the arm of a chair so poo poo doesnt fall off the table when you solder on it

over the weekend i replaced the blazer distributor and drained the gas. There was about 4ounces of rusty water in 5 gallons of gas. bad poo poo. Distributor body got modded with a dedicated ground terminal, as by stock they ground through the distributor clamp, which is lovely and stupid Tore off the carb, too, it is in better shape than I thought. has a brass float so i dont have to replace that, and I found the rebuild kit online. carb is sitting in pieces soaking in carb cleaner on the bench.

i started a new job so my programming projects have been languishing, although i wasn't really sure where i wanted to go next since i had written that basic 3d renderer essentially from scratch, a workable if simplistic cfd simulator, and a physics engine that could do elastic collisions and gravity and such maybe i should try to write a finite element modeler or something of that sort, iunno

not gonna defend python's performance too hard, but as long as you're not doing anything too exotic there are a lot of libraries that provide python bindings for C/C++ implementations of computational-intensive things. numpy and scipy are the big two, and they're fast enough to (gradually) replace the horrific mess of fortran, C and MATLAB the physics community has accumulated over the last 30 years seeing as you're the kind of guy who writes his own raytracer though yeah maybe tossing it over the wall to a library is defeating the point of the exercise e: if you want a pile of new math to gently caress with and you want to build on the CFD stuff, face to magnetohydrodynamics coffeetable fucked around with this message at 16:47 on Oct 17, 2013 |

ol qwerty bastard posted:yeah i dunno, maybe use a wavelet model to simulate light interference through a slit or grating. output to a file and make pretty pictures with gnuplot, or have a realtime output maybe with adjustable parameters. model various things rolling down ramps or along tracks under the influence of gravity. take into account friction and angular momentum. model some rollercoasters and calculate if a human could survive them make a pendulum simulator, then make a pendulum on earth simulator taking coriolis and centripetal forces into account.
