mains transformer in electronic projects part 2

June 29, 2009 - 9:28 pm 1 Comment

The importance of a galvanic coupled/galvanic connected (iron) enclosure for an electronic (audio) device to prevent hum, cracking sounds, disfunctioning and strange other fenomena of your home brew radio or audio amplifier. The reason is to equal out possible potential differences between parts of the enclosure. Potential differencies can lead to small (tiny) Voltages and resistances that can disturb the good functioning of electronics. So solder all the parts of the enclosure together by (a) wire(s), if they are made from separate sheets of metal. Also on connections made with bolts and nuts potentials can occur when they get corroded and in that case “transfer” resistances can build up on which small Voltages occur. So soldering (100 Watt soldering device) is the best way to make the connections in the earth-circuit. Enclosures of aluminium can give problems, because some types of aluminium have a tightly closed oxide skin with a high resistance on which it is difficult to break through, connecting the earth wire. Aluminium cannot be soldered, so you have to use bolts and nuts (use a sharp ring under the bolt/nut to punch through the oxide layer). Measure the ohms resistance in the earth circuit (wires to the earth point of the enclosure) if you construct an aluminium enclosure for an electronic device. If you watch this video on another website/channel please check YouTube for the recent content. More about simple power supplies in my book (”Schematics 1″) on the website of Lulu.

Vantec Nexstar 3 HDD Enclosure with FireWire?

June 28, 2009 - 11:27 pm 1 Comment

I want to buy the Vantec Nexstar 3 HDD Enclosure with the two extra FireWire ports (NST-360UF-BK), but I am wondering, is it worth my while to buy it even when it is two times the price of one with only USB ports when FireWire 400 gives the same transfer rates than USB 2.0?

If someone owns one of these, can you please comment on your experience with this device?

And anyone else, please correct me if I made any mistakes regarding the features of the device.
OK, I know SATA is faster, but do I need a SATA harddrive to get that type of transfer?! Can you use regular IDE on SATA enclosure and still get a fast transfer?

Fire wire is faster then USB 2.0 but then SATA is ALOT FASTER!

Firewire is 400 mb/s
USB 2.0 is 480 mb/s (but you never get that
SATA or ESATA is 3 Gb/s

Get External Sata if you dont have money get firewire
