Rocket Economics: The Dismal Rocket Science.
Solder paste does a fine enough job of keeping the parts in place durring reflow.
BGA packages are actually better than many larger (DFN) packages for vibration (from what I've read)
better question is why not? It does the job does it not? not everyone is so driven to be fashionable.
$15K Tek scope I have is great but having to update a Oscope firmware because it has bugs in the is distressing. When set to trigger from the logic analyzer it would fail to sample the analog every other trigger. The prices for the serial decode is ridiculous but It has saved me many many debug hours and it wasn't me paying for it so..
That unit is a Velodyne HDL32. Neat device, it has 32 indvidual laser diode, reviever diode pairs. I can vouch for the precision being 2cm as advertised but not so the accuracy. It may have changed but is was necissary to calibrate each one of those 32 channels to get them to all report the same range. After calibration it was accurate.
Velodyne is a bit of an odd company. They started making audio stuff and almost as a lark decided to make a Lidar (Ladar) product.
you know... from star trek.
In the future everyone will have a microbolometer. They are so damn fun and useful I don't want to live in a world where they don't.
Low res models from FLIR are now about $1000.
Maybe you should move somewhere sunnier?
I started replacing failed bulbs with Phillips LEB bulbs 3 years ago. I have seen 0% failure rate. I don’t get so angry with the kids when they leave them on. They are instant on and dimmable. I have no complaint about the light spectrum.
But I live in sunny Colorado and spend a lot of time outside. Maybe if I lived in a persistently overcast region I would care more. I suspect though you just like complaining about light bulbs.
only to be used in case of an adverse situation right?
or something using BOLLOCKS
In heated envoronments all waste heat offsets heating costs so is not wasted. How often is an English house running its air conditioning? Waste heat that cannot be harvested for heating is of course waste so turn off your outside lights. Seems like worrying too much about electricity consumption in your area is a waste of time.
That just the thing buddy... evolution is the best fit for the available evidence. Alternative explanations (we call them hypothesis) have to be able to fit a lot of pieces into place and do it better than the existing explanation. If you are suggesting that developing that alternative explanation is not supported (rubbished) because too much has been invested in the status quo, well yes that is sometimes a problem. But it is a human problem and the best hypothesis seems to win in time (the old generation dies off). I don't think that is what you are saying. I think you just a shallow troll. You also seem to be confused by "belief" and building testable hypothesis.
I suspect it is a product of proximity and potential harm. A fast massive object can be unsettlingly close at 11 times the distance of an object that is 1/11th as menacing.
I don't know... let us find some lawyers and pay them millions of dollars to find out!
They should fall in line after that. If anything scares Linux kernel devs it is someone shouting at them on the internet.
I've never heard the term "hash filter" outside of people rolling their own special cigarettes. Is that like a the RFI choke?
It would not be very expensive to make a circuit board that would fit in a itingy charger like space. Micro controllers are available in CSBGA these days and circuit boards are pretty cheap. It would be thousands of dollars including engineer time not millions.
A PCB is made up of sandwiches of epoxy, fiberglass and copper. I doubt ants can sense glass or copper but they might be picking up a chemical signal from the the epoxy. A small change to the epoxy chemistry might put them off.
It is not clear to me that they are attracted to the PCB though. It could be a chemical signal from wire insulation or something to do with electric fields. Some research is required. No matter what it probably doesn't make economic sense to make special electronics for what is now such a small market segment. Some other mitigation is needed.
and make sure the label says "fresh".
Maybe it got personal because the dish CEO is generally known to be a dickhead. Japs are saying "You don't really want to work with THAT guy, do you?
It looks like they are using a Novatel OEMV which in the configurations I'm familiar with will run you about $6000. An IMU on the from crossbow similar to the one they describe is another $6000. I guess it is better than the $100K systems that some reaserchers strap on their systems but not cheap.
IR filter could probably counter this counter measure. If these cameras use silicon detectors then they may already have an IR filter in place.
You are not going to penetrate very far into the soil. Even if you did it is trivial to toss down a box of worms after the radiation. One way the device could work is you microwave an area to kill the existing plants and seeds and then till the soil.
So did I !
want to hang out later?
I misread the title. I was mighty confused by the first paragraph of the article. I then read the title correctly and was mighty disappointed.
Once I had a pilot come on the intercom before we started to taxi saying something to the effect of "whoever has the elctronic device on, turn it off. It is interfering with out navigation equipement". After the flight as I was deboarding I walked by the pilot and asked him if he was kidding. He was serious and said no his GPS was giving him the wrong heading until after he made the announcment. I still think it is bullshit but apparetly some pilots think otherwise.
I'm glad they used the term LADAR instead of Lidar. Lidar sounds so limp.
I've heated semiconductors to >400C before but the result was less good. There was less self healing and more molten jets of plastic and smoke. I must be doing it wrong.
They orbited the moon. They also orbited the earth but in the same way that when you orbit the earth you are still orbiting the sun. It we all go round and round.
"Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour
That's orbiting at nineteen miles a second, so it's reckoned
A sun that is the source of all our power"
The Norsemen were pretty savage.
@ seiñor pott I do posess the ability to subtract 2005 from 2012 :-) it goes <windows key>+r and then "calc"
We have since purchased another alienware for the lab, I think 2 years ago. I have not used it as it ended up in the hands of one of my managers and I never saw it again. I think it performs just fine.
We bought 3 alienware lappies in about 2005. They used P4 chips that got so hot when rendering data they became uncomfortable to type on. Putting them on a lap would be spermacidal.
I bought an XPS earlier this year based on the reputation of the the old good XPS that is still running fine after many years in the lab. I sent it back the next day. The build quality was pure crap, not the fine machine my previous experience indicated it would be.
Now if he would have set off a small model rocket while he was up there....
LPKF can do it but you need a lot of equipment.
What a fantatstic Idea!! i need to go set up an exchange right away!. Unfortunatly I'd probably have to spend all the stolen money protecting myself from hitmen.
The criticisms really are over the top. If you don't like the idea then don't use it. Paypal is still accepted. I'm pretty sure I don't understand the concept fully as I've only read the Spectrum article on it and The Register has helpfully pointed out some of the problems with the practial use of the currency but it is very very very neat technically. I have no desire to do anything illegal or untrackable but I am interested enough in the cryptography and technology that I find bitcoins facinating.
What was my point again?
I can not comment. But I wanted to share my personal experience. In my youth I bought many games but pirated many many more. Since 2006 though I have bought and played 3 games (and pirated 0) and every second I was playing I felt guilty for using my very limited free time not with my young family or doing something useful. I can't handle that stress.

A fine statement of truth. I am at a loss as to why anyone would have a problem with what you said. Is it because you called their house pets "stray"? People need to think rationally about this. Emotion is clearly clouding their judgement.
I here-by enter into record House Resolution #4721: the georgecloonylookalike "F*ck Them Pussies" bill of 2012.
This fills my heart with glee.
My fellow engineers and I have postulated that boards are immune to ESD as long as the source of the ESD is the person who designed the board. Maybe they designed it.
Also nothing bad can happen to you as long as you are wearing an ESD wrist band. (plugged into ground or not)
One of the consequences of knowing the diference between Volts, Amps and Watts is the painful twinge you feel when they are misused in conversation or reporting. The pain is felt quite often and I suggest it is even worse than the pain others feel from the whole there, their, they're problem.
When this man joined the military he gave forth this oath. "I do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God."
This, as well as when he accepted a security clearance, placed upon him responsibilities above and beyond those of a normal citizen. In my opinion he violated his oath and the duties of his security clearance. Whether this was an act of valor or treason is irrelevant. Until and unless he is pardoned he must be prosecuted.
that is all I wanted to say. Proceed.
This just a ruse by LinkedIn to get you to visit their website again when you change your password.
The total failure could very well be heat related. The power supply and other parts need convection to keep cool. Convection is not possible without gas. Your faulty altitude readings might also be related when the analog voltages went out of regulation or got too noisy. If there are any electoytic caps they might have failed as most are rated to only modest altitudes.
US Mil did for a while have a spec that demanded the physical destruction of flash media. I have been told that they have since relaxed that to where some kind of errasure is sufficent. Silicon Systems was one company I know that made them. http://en.wikipedia.org/wiki/Silicon_Systems_Inc
Typical govt turf battle. Taking advantage of taxpayers is HIS job.
I appreciate it was a pedantic point of order but... San Francisco and probably the 20 miles surrounding it can safely be referred to as "San Fran" by people who do not live there nor give a shit. I lived for many years in Fort Worth Texas. Now that I don't I tell people I used to live in Dallas for simplicity.
