The family of Eddie Smith has auctioned off their late father's 1967 Ferrari 275 GTB/4*S N.A.R.T Spider, and generously donated all the proceeds to charity. The rare car (only 10 were ever made) was sold Saturday night at RM Auctions in Monterey, Calif., for $27.5 million. That price set a new world record for the most expensive road car of any kind sold at auction.  Smith took ownership of the Ferrari in 1968, and his son, Eddie Smith Jr., told the auction crowd that selling it was "a bittersweet moment." According to the Los Angeles Times, he advised its new owner to "Drive it, love it, enjoy it, and more importantly share it with others so they can see it."

One of the basic building blocks of electronics project is building your own DC power supplies from an AC source of 110 V.A.C or 220 V.A.C.The common DC voltages that are necessary to power up the devices are usually in the range of three V DC to 30 V DC. Usually the fixed types of DC voltages are 5V, 9V, 12V, 15V & 18V DC. With the advancement of know-how, lots of devices are using one.8 V DC these days. S M P S is becoming common these days as the demand for miniaturization due to space constraints increases.  Take note that for linear power supply projects, you need to make use of a step down power transformer to step down the AC voltage from the line voltage of 110 V.A.C or 220 V.A.C before using it to supply to the diode bridge.
