A GOOD DC POWER SUPPLY USING A SCRAP NOTE BOOK CHARGER
DC Power supply is an indispensable part of any design. Notebook adapters are cheap, of good quality, compact and with output power ratings around 80W. You can even find several of them in the hidden corners of the house, scrapped from old notebooks. It would be great if I could use them for my designs. But unfortunately they have weird output voltages like 16V, 22V etc. whereas I need 5V, 9V and 12V.
