Oh it more than hurts.. When i was 13-14 or so, I was having fun outside after church showing the other kids how one could charge and make a spark and recharge and make another spark... I then accidentally touched it with my finger and instantly vaporized two tiny spots on my finger... charred ash.. smelled like a bug zapper hahah... I think i've been shocked by just about any electricity one can find in most households, from 120vac mains to electric fences to 25kv flybacks from old monitors :D
I think, you need to use multimeter or something like that to discharge your caps. Capacitor inside camera might not kill you, but it is best to have a habit of discharging caps.
Around two years ago I had a flash capacitor discharge on my forarm and I still have the marks from the two points where it touched my skin. I can't remember the rating all I know is it hurt like hell.
On top of that being the ND filter, it is really a substitute for aperture. So there is a fixed aperture for a given focal length, determined by the lens, and there is this filter which provides a second aperture opening. Pretty common on cheap cameras, this (usually 4x) filter is used in strong sunlight and waterfall 'magic' modes.
That was an ND filter, a subtitue for lowering the light amount reaching the sensor, since the aperture can't really go down to f/8 or f/11 in these cheaper cameras.
Camera looks so innocent but that cap is why electronics scare me. I'm bit interested but hate the thought of getting a shock :) was shitting bricks the other day just trying to sort out the mains charger for the hair clippers other day. It had cracked open and partly fell out. Didn't understand the inners but got it back in and hot clued the edges.
I really enjoyed this video. it's wonderful to see that you can actually show some of the parts work independently, it was quite fascinating to see the shutter at work. Any idea what the tiny mobile filter inside the optics does? Is it just a regular gray density or something more peculiar? Anyway, thanx for this great teardown, I'd like to see more cameras insides. Cheers.
At approx.19:00 you employ a signal generator to actuate the shutter, you mention the wave form, bipolar....19.... something? Could restate the specs for me, and to satisfy my curiosity, can you mention what signal generator you use, I'm shopping for one and am looking at a rigol dg1022a, dg4062, any input you offer would be appreciated. Your vids are the bomb,keep up the interesting work,and thanks for taking the time to share out this otherwise unseen view of the technology that surrounds us.

ReplyDeletemike i love your videos but for the love of god, cut your finger nails
ReplyDeleteWarns about being careful not to take a shock from the flash cap, takes a shock from the flash cap :))
ReplyDeleteGreat teardown. Thanks.

Truly fascinating video. Keep it up!
ReplyDeleteGreetings from Bolivia.
I wonder if it's possible to hack the IS to give a tilt/shift effect.

ReplyDeleteInfrared actually turns hot areas purple. Techmoan demonstrated this in one of his camera reviews.
ReplyDeleteshutter use = electric shuter for 35mm filme cameras... electric for fine shutter time tuning
ReplyDeleteDesoldering braid - I reccommend Chemtronics Soder Wick brand (despite that they can;t spell solder)
ReplyDeleteSay, where did you get that de-soldering cord stuff at 6:20?

ReplyDeleteBloody fascinating, thanks very much :o)
ReplyDeletethis camera actually looks quite similar to an old canon powershot. wondering who did it first

First LCD i took apart was a 24" desktop monitor, the optical sheets amused me way more than they should have.
ReplyDeleteAh, thanks for the reply :)
