I've always said the word genius is bandied around way too much, and this video is a fine example. CRT screens/tvs follow the same idea - individual lights illuminate in sequence quickly enough to form a static picture, each pixel changes very slightly 100 times per second (refresh rate) to give the illusion of the original picture in motion. The CRT beam scans ("rasters") from top left to bottom right (for example) in exactly the same way that the device in the video spins (it rasters in a circle) and however many times it spins per second is the refresh rate.

It's a cool project and his PCB work is nice, and he's done a good job of translating a picture into a timed set of lights. The videographer uses the term genius because he was not previously aware of the long history of rasters. This would be a useful tool for teaching children about the process - CRTs might not be popular anymore, but CCDs are fundamental to (astro)physics, and the principles behind both cover a huge range of potential teaching topics.

I was unfortunately surprised to learn that my butcher block home workbench, or more likely the varnish (looks like polyurethane to me) in many spots has a very low resistance (<0.5 ohm/in as I measure). Fried a PCB I was working on, which I took a lot of shit for, everyone assuming I'd just done something stupid. Anyways, the moral is don't assume your wooden bench is actually an insulator.

Oh, and I also don't recommend playing with a a transformer out of a microwave unless you really know what you're doing. Though it's probably safe enough, 2kV will arc pretty far through air, so you don't even have to actually touch it to have a bad day.

Thanks They're a rather competitive breed!

Did you notice that the guy who was leading was also wearing Fernando's helmet? Daytona motorsports said it was his friend Alberto Albirales.

The tank mods are added by retailers and print shops. You're right about how the system works -- the lines run from the big tanks and are inserted through a hole drilled into the carts small reservoir.

One issue with that is that most cartridges have a software page count that is used to tell you that the ink is running low / empty after a certain number of prints. So, along with the tank install, most shops will put in an aftermarket chip or PCB that resets or bypasses that counter.

For the other question, I think that Thailand still relies on printed documents more than in the US, but it is going down. I undoubtedly have a somewhat skewed opinion on things since I am a teacher, though. I teach 18 different classes of roughly 40 kids once a week, with a worksheet or some other printout being used nearly every week -- so I probably burn 700+ pages each week through my school's copy machines. Then I teach smaller private classes at home, with maybe 100 or so pages a week on my own printer(s). I have one inkjet with those tanks installed, 2 mono lasers, and 1 color laser... So yeah, I probably am a much heavier user of printed stuff than your average person.

Wow... So many great points here.
And lots missed by others.

@ChaosEngine I like you too. But the next posts after yours explains my point better. @Eukelek got the point correctly.
(The fact you don't eat it, or your local farm doesn't grow GM is telling and hypocritical)

There is a massive difference between selection using natural processes and GENETIC ENGINEERING.
One will only produce offspring that are genetically compatible.
The other is a crap shoot producing mixes of different taxonomy.
For fucks sake when could A FARMER BREED A MOUSE WITH A JELLYFISH, or mix SPIDER GENES WITH GOATS.
That shit is fucked up and only the tip of the iceberg.

You really want MONSANTO creating NEW SPECIES OF PLANT THAT ARE STRONGER THAN THEIR NATURAL COUNTERPARTS AND LACED WITH TOXINS AND PESTICIDES ????
It was Monsanto that developed AGENT ORANGE, and PCB's which THEY ALSO DENIED WAS HARMFUL EVEN THOUGH IT IS MASSIVELY CANCER CAUSING. They buried every study showing it was carcinogenic.


@nock . Yes I'm sure the medical profession has even crazier biology going on. But I would only use that shit IF I WAS GOING TO DIE.
NOBODY NEEDS GMO.
Now the medi-corps are using super viruses as vectors for 'custom' dna treatments.
Considering that the U.S. CDC was just admonished for improper practices contains viruses. How long before there is an incident that is completely synthetic (man-made) and completely irreversible.

@RedSky Sure Africa should grow whatever it needs to survive. But don't expect an export market for gmo.

Production costs will be higher than a single PCB phone, if there is any traction on this modular phone, the current phone manufacturers will probably drop their margins until it can't compete in the mainstream market.

and btw. GMO PROTEINS ARE NOT THE SAME

ALSO

Monsanto developed AGENT ORANGE and PCB's (cancer causing pollutants even though they fought and denied it)

This guys points are very valid.
I'd be happy to see a modular standard (like ATX) for notebooks/laptops, but there is none.

Truth is - for portable devices consumers demand them to be smaller, cheaper, and have better battery life. PhoneBloks would be larger, more expensive, and more power hungry than the highly-integrated designs for portable electronics nowadays.

I think a practical starting point would be a standard "socket" for an SoC, which could be upgradeable. The part you keep would be the screen, pcb, antennas, etc. The SoC could itself be an MCM, with multiple stacked layers. You would have to upgrade this "base" once in a while too, but only with release of new wireless standards that work at different frequencies.

Having a standard size & voltage lithium battery for phones would be nice too. Could anyone imagine how much it would suck if AA and AAA batteries didn't exist for other electronics?

I also vote microSDXC as standard for flash storage.

handling that melted PCB without gloves is just asking for cancer...

The thumbnail image for this video has been updated - thumbnail added by Boise_Lib.

and i will add that scientists, while doing some amazing things, also routinely kill people.
pcb's, bovine growth hormone, nuclear radiation, nuclear bombs, bio-warfare, missile technology, ddt, malathion, agent orange, you name it, scientists, in the name of profit, have compiled a laundry list of chemicals, compounds, and weapons that accidentally or purposely kill people.
Western medicine, in their wisdom, also routinely kill people. it's called "iatrogenic death" - or, death by doctor. One of the most common ways to die.
Monsanto exists to make a profit... period.

That is a Ship-breaking operation on the coast of either Pakistan or India or Bangladesh.
http://en.wikipedia.org/wiki/Ship_breaking
It's one of the worst examples of labour exploitation and environmental destruction in the world, It's performed in these countries because of non-existent environmental and safety laws. They essentially just run the old ships onto the beach and dismantle them by hand. Some of the hazards that the workers are exposed to, other than being run over by freighters, include PCBs and asbestos. 40,000 people live in a shanty-town in Alang, India doing this job, and on average 1 worker dies per day.


Yeah I was about to declare "fail" until I realized "they meant to do that."

Sad business, funny 'parking job.' Love the sub-caption.

Quite original! I cannot imagine the costs to this poor guy though making all those PCBs even for something cheap like that.
