lamer journeyman Registered: 30/01/2002 Posts: 87 Loc: Texas	I want put a Linksys WAP11 in my car so I can d/l songs without removing the unit. I am having a hard time finding a 5V 2.5A car adapter for the WAP11. Any ideas? I am positive I have read about an install including this, but a BBS search came up dry. _________________________ MK2a 160GB 11 Years later, these Mk2a units still rock...

I am having a hard time finding a 5V 2.5A car adapter for the WAP11. Any ideas? i A high-current version of a 7805 regulator should do it (or adding a shunt transistor to handle part of the current to a standard 7805. Circuit is i the appl. notes of the 7805, IIRC). Thatl'l waste a lot though - roughly 20W in heat, so you'd need a fairsized lump of metal to cool it... A switching power supply would be much more efficient, but I have no design handy... lot more complex to build tho... Another brute force approach would be a 12VDC->110/220VAC switcher and then plug the stock power 110/220VAC->5VDC adapter into that... Also somewhat wasteful, but probably less so than than a 7805... _________________________ /Michael

There's quite a range out there these days, and you should find one to handle that current OK _________________________ (list 6284, Mk1 S/N 00299 4GB blue [sold]. Mk2 S/N 080000094 20GB blue)
