bionic leg

Filed under: Bionics, technology, Uncategorized — ellitoguy @ 1:44 am

seeing as i’m in a cast due to severed ligaments, the other day i was pondering ways to make some sort of bionic/mechanical leg work intelligently…

now, the way i thought about it, most of the things we do with our legs tend to occur in a fairly symmetrical manner, e.g. when walking waht one leg does tends to be a mirror image of what the other is doing, one leg then the other… so, i figured, if you get a computer to process what one leg, the ‘good one’ is doing, you can put the mechanical one on some delay loop to mimic the biological leg…

i thought it was a pretty smart idea, hehe, and one that would be realtively natural … however, as these things usually go, a couple hours later whatever news channel we were watching showed the story of a former soldier who had a leg amputated in iraq or afghanistan who had a bionic leg that did precisely that… lol

he wears an ankle bracelet of sorts that sends the data to the other mech-leg, and therefore can live relatively naturally…

anyhow, i cant find the story itself, but i think this is what they were talking about: Ossus Power Knee

edit: even if this wasnt the outlet i saw it in, pretty sure this was the story

Digital Canonet

Filed under: photography, technology, Uncategorized — ellitoguy @ 11:10 pm

The other day enforcer and i were throwing around the idea of a digital canonet– essentially a digital mini-rangefinder that would allow for super-discrete street shooting… basically an even smaller leica… there are certain things like this on the market both in film and digital formats, but all seem to be plagued by certain imperfections that make it a no go… take the canonet for example, known as the ql-17 (and variants), super compact package, pretty fast and handy 40mm f/1.7 lens, and full size 35mm frame… [ ]


trouble is, the rangefinder absolutely sucks, its super dim, terrible to focus, at least in all the ones ive played with… nothing compared to my m7– a deal breaker

then, there have been the digital models, like the ricoh grd [ ] which while seemingly very promising, failed to deliver given the crappiness of the sensor…

ricoh grd

— Along comes the Sigma DP1 [〈=1&parent=14&idca ]sigma dp1

generally their stuff isnt too incredibly exciting camera-wise, at least to me anyways, because their slrs have the proprietary sigma mount, and seeing as i have an extensive investment in canon glass, that in and of itself makes me discount them as viable cameras.

however, the dp1 is a compact camera, not an slr, nixing the above problem.

even cooler though, is that rather than having the tiny sized piece of crap sensors we’re used to seeing in point and shoots, sigma took the bold step of building a compact camera around the same sensor they put in their to-be released DSLR, the sd-14!

pretty cool, perhaps this camera will do the trick, because the sigma foveon sensor will indubitably kick the ass of any point and shoot it comes across, and perhaps even be comparable to my 20d.


All i want in a compact camera is this cameramakers, make me one and ill buy ten:

-1.6x or even full frame sensor, that delivers excellent high iso capabilities, ill take 6 mpixels, 8ish preferably

-fast lens, maybe something like 28, 35, or 50mm focal length in 35mm equivalent

-aperture priority, as thats what i shoot in most of the time

-compact size, and a decent, bright viewfinder, and thats it! I’ll be perfectly happy with manual focus, and prefer physical buttons to digital menus.

gimme that and ill carry it with me everywhere and be merry
