Given an old battery lantern w/long-ago hacked in 6v GelCell, butnow alas a dead PAR 36 lamp, and a 30+ LED headlamp, with a majorembarrasment to its case [and the owner's knee..]; clearly the answeris a West Virginia shotgun marriage.The LED's ran on 3 AA's, with AFAIK, no current limiting beside theAA's Rsubi. The owner reports they drew ~800 mA. Now I can do Areequals Eeeee over Eye as well as the next guy, but it occured to memaybe there's some magic regulator I should use instead. Is there acheap low-dropout regulator suitable for this task?Or should I start cutting traces, put all the LED's in series andthink DC-DC inverter????-- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUXUnless the host (that isn't close).........................pob 1433is busy, hung or dead....................................20915-1433
