I just finished building a Voltage Booster kit to power my notebook computer. The notebook requires 19V to keep its battery charged, and I plan to use it mobile in the next Florida QSO Party. The booster will plug into the car cigarette lighter and provide the 19V, 3A that it needs. An article for the kit appeared in July '97 QST and is available for $21 plus shipping from N4UAU. He has a website, but I didn't save the URL and it doesn't show in the article. But it should be easily found with a web search. Oh, the hardest part in the kit to build is winding two toroids. :-) ===== 73, Bob Patten, N4BP Plantation, FL E-Mail: n4bp at yahoo.com Website: http://www.qsl.net/n4bp QRP ARCI #3412 FISTS #7871 ARS #799 SOC #1 Whiners #6 ++++++++++++++++++++ Date: Thu, 17 Jan 2002 16:21:59 -0600 To: elecraft at mailman.qth.net From: Tom Hammond =?iso-8859-1?Q?N=D8SS?= Subject: Re: [Elecraft] Voltage Booster >--- John Clifford wrote: > > Is it possible to step up a DC voltage to a higher voltage > > (but lower amperage)?
