nice little camera

Den torsdag den 17. april 2014 03.54.26 UTC+2 skrev John Larkin:

if it is like almost everything else USB it will charge from a computer, though possible only when it is off

and most PC can't charge with 2A like a dedicated charger

I bit the bullet and bought a new phone, always have it in my pocket anyway excellent camera and it will automatically transfer images to dropbox when ever is has a wifi connection (or data connection if you let it)

-Lasse

There's a protocol (actually several) for the charger port to tell the chargee what current it can supply. It uses divider resistors on the (otherwise unused) data lines.

Here's a M*x*m chip that emulates chargers:

So it could charge much slower, and at least it's possible, it could refuse to charge at all, depending on their intent and what's inside the computer and how well it pretends to be an adequate charger.

The camera can recognize the charger by the DC voltages on the data lines (D- and D+). While there are defacto standards for powering Apple, Android, and other devices, there's nothing to prevent Olympus from inventing their own "standard" thus requiring purchase of a genuine Olympus charger.

You can get a USB charger tester: I have one on order, but it hasn't arrived yet.

It does charge from my computer's USB port.

And it has a really good interactive HELP system built in!

** Like so many others, it has NO optical viewfinder - which makes it near impossible to use outdoors in sunlight.

I have owned two Canon pocket cameras, an A430 and an A1200 which DO have optical viewfinders. They work well and even track the zoom lens as it goes through its range.

I'm looking for a low cost video camera...The cmos sensors in cell phones should create them, I figure. In looked at one around $1000 - waiting patiently for that to turn into $200. It's all beach sand, right? :)

Wow, they'll discontinue it immediately

That $85 Olympus has a super-macro mode that focusses to 1 cm, which means the lens is almost touching the object.

The problem with that many pix on a small camera is holding it steady enough.

That's why we have tripods and such.

object being photographed. I made a little LED ring light for such occasions. With 14 Mp, I can use Irfanview to zoom in on a tiny areaof the resulting photo and still have a sharp, high resolution image.

Not if it has image stabilisation. My wife's latest camera - the Panasonic Lumix Digital Camera DMC-XS1 - has it in a very slim package, which suits her. It replaced a similarly compact Casio Exlim EX-S600, which doesn't have image stabilisation.

She started off in photography lugging around big Nikons (and got me to lug the heavier accessories from time to time) but got converted to cameras small enough to go everywhere with her, all the time, when digital image sensors hit 5 Megapixels.

She was moved to the most recent upgrade when her friends started taking better pictures with their I-phones (which do have image stabilisation)than she could with her Casio (which doesn't).

Yes, but to get close up views yo udo not need mega-pixels and expensive cameras.

Need to buy some of those stereo glasses some day, those are getting cheaper.

$85 is not very expensive.

This is a PTH with a plating defect on an inner layer. This board had lots of them, even though we'd paid for bare-board testing:

Kinda fuzzy. These were done with my inexpensive Sony camera:

I document breadboards and prototypes with photos of whiteboards, the hardware, and scope pictures.

Yes that is all very nice, my Canon A470 in macro mode, when on tripod can do real cool pictures too (usually set auto timer to 2 seconds, so it really is no longer vibrating). But for that camera .. grab the moment:

So many cameras here, more on the way:

Macro:

But still 16M pixels is a lot. The big problem with these digital cameras versus a mantis is the latency, its slow, annoying if you have to do soldering for example. So for that I have some small PAL cameras, and small monitors:

this is just a few hundred TV lines resolution, but no latency:

The PAL cameras look like this, you can turn the lens and get really really close:

This is Canon A470 looking through a cheap microscope wit hEL backlight experiment:

In short you can make things as sharp as you want... It all depends on what you want the pictures or video for.

I like stairways. San Francisco has lots of stairways. There's even a paperback guide book.

Actually, I mostly like to take pictures.

I grew up in New Orleans, flat and hot, mostly below sea level. The highest I ever got, as a kid, was Monkey Hill, 12 feet high.

That's why I like SF. It's so three-dimensional, which means it has views. And it's almost always cool.

These are 2 blocks away:

I couldn't stand living in a big city like New York, all concrete and steel.

You guys do mud really well, though. Even better than the Welsh, which is going some. ;)

Thats is very nice, really.

definitely need grass cutting ;-)

I grew up in Amsterdam, but lived in many different places... Skyscrapers do not really bother me... Lived on a top floor for some years, overview of the whole city, expensive.
