Hey guys, so I`ve been working on this project for a while now, and wanted to show it here because you are a cool bunch.
if i mess up, the pics are too big, or whatever, im sorry. let me know and ill fix it asap.
the title is pretty explanatory so here are some pics of the thing, and the associated mess (if i actually manage to attach pictures correctly)
i know there is nothing particularly interesting in this from the microcontroller point of view, but maybe someone will like it.
its sort of based on a liebherr lr1750 crawler crane in case anyone is interested. it is controlled with an ir remote kindly donated to the project, mostly made from scrap from my junk bin and some chips i got from the VERY generous TI`s sample program. The base, for example, is made from an old hdd, and the hole thing is screwed to, and pivots around, the main bearing.
Some stuff i had to buy though, like the leds.
I was thinking what could I do with a lot of solid conductor wire i pulled from the walls in my house when i changed the [way too old] electrical installation. i thought a lattice structure would be fun, and i have to say, its amazing how rigid the thing got. i also wanted to do some switching led driver experimenting. I used a TI TPS61199 led driver with 32 "5050" leds, that have 3 chips per package, so its 96 leds in all, at 17 mA each. the leds are mounted on a structure that is supposed to resemble a section of Eero Saarinen`s twa flight center. a sort of rebar core type thingy for the roof.
i wanted to do a solid thing for the lamp, but it proved somewhat hard, i still might though. I´m very pleased with the amount of light this produces. its about the same amount on my working surface (13V @ 650mA) as the produced by the fairly bright heater that is my other lamp( 12V? @ 5 A) with a halogen spot light . it also comes down vertically, wich is great.
keen eyes will know where the button cap came from.
it works pretty much the same way the original crane does, with spools and pulleys. all handled by the absolute overkill g2955, of which i´m just using the timers, and some random h bridges.
the code is not something any of you would like to see, believe me.
anyway, hope someone finds this interesting.
