PCB Manufacturing

I was wondering if anyone knows a cheap place to get some PCB boards printed? I used ExpressPCB to create the board (first thing I found on the computer at work) and it's giving me a .pcb file. I assume this file-type is pretty standard? I tried using their built in pricing software, but it seems a little pricey for small quantities. Any suggestions?

This is a 3" cabinet pull. It caught my eye as a super steam punk component. Just imagine it with two LEDs inside the cage. Anyway how is it made ? That unit is magnetic, has 8/32 cabinet threads, solid otherwise and the cage appears 3/4 rotated This object would be perfect for 3-D printing.

How are spherical rare-earth magnets manufactured? Answered

A question came up the other day when playing with Buckyballs of how you manufacture spherical rare-earth magnets. I'm surprised they could use that name, given the original Buckyball, but these Buckyballs are powerfully magnetic spheres with one side a North pole and the other a South pole which can be stuck together to make 2D and 3D structures.  Sale has been restricted in many places because of people ingesting them and requiring emergency surgery. I've found information on neodymium magnet production using a sintering process, but can't see how you could produce a perfect Ni/Cu plated sphere with this method as individually machining to a sphere would be excessively laborious and tumbling would be a non-starter because of the attraction between balls.  EDIT: The sintering page wasn't the one I thought I was linking, but the one I've linked looks like it may have the answer in die-pressing or isostatic pressing in the aligning field of a solenoid.  Is this how it's done for spherical magnets? (Polishing the coated spheres would still be a problem.)

Nissan invests in electric cars

Motor-manufacturer Nissan have announced a £200 million ($330 million) investment in a factory intended to produce lithium ion batteries for electric cars.Along with the news from Nissan, Peter Mandelson (Business Secretary) said a "low-carbon economic area" would be established in the North East.As part of the project, 750 charging points would be installed across the region and a training centre specialising in the manufacture and maintenance of low-carbon vehicles would be set up. "The North East has distinguished itself as the first specialised region for ultra-low-carbon vehicles," Lord Mandelson said.The announcement from Nissan comes only days after its Japanese rival Toyota said it would start manufacturing the new Auris hybrid petrol-electric vehicle at its plant in Burnaston, Derbyshire from mid-2010.

Identify WW1 20mm shell casing?

A WWII veteran friend of mine has donated two shells collected on the battlefield in WWI by his father. Following are some photos of the shells: I have tentatively identified them as 20mm HE shells but would like more information, such as manufacturer and probably use. The first image shows both shells. They are 20mm in diameter, the brass casing is 70mm, the steel casing is 49mm and the head is 25mm. The steel casing shows an A and what appears to be an exploding shell. The other two images are of the bases. The letters at the top appear to be B &S;  but could be something else. I believe this is the manufacturer's mark. The 18 should be the year of manufacture. I have no idea what the 125 on the left means nor the numbers on the bottom which are hard to identify. Any assistance would be appreciated because my friend, who is now 95, would like more information concerning the shells. Thank you. Roger Laplante

How would a stronger magnet impact the performance of a speaker, and what impacts the overall quality of a speaker? Answered

Okay, so I had decided to build a sub-woofer for a speech topic for school, and I was wondering what it was that made speakers, or sub-woofers so loud an efficient. Granted, I know mine is far from great, while being made from ply-wood, duct-tape, and everything, but why is it that professionally manufactured speakers are so loud by them-selves with minimal power? I am using the circuits from my Logitech X-240 system, and the sub-woofer is always way louder than that of my home-made speaekr, with a significantly smaller ceramic magnet, it seems. Is it the geometry of the speaker itself, or what? What do manufacturers do in construction which improves the sound, or quality of speakers, and would using a neodymium magnet be better than using ceramic magnets? Any help is appreciated, and thank you in advance.
