I'd still go with the LM3909. It does wonderful things to battery life. I used to build display model aircraft. The first was a B52 (yep, da BUFF) that used 555's to run the strobes. A 9v battery lasted about 2 hours. The last one was a large Tomcat - with 2 seperate beacons, INCANDESCENT strobes (they look GREAT!), cockpit lighting - the works. Two D cells in the tailpipes lasted over a year (using LM3909's and CMOS logic chips). One idea (not yet implemented) was to make _WORKING_ _SCALE_ radar display screens! Can anybody guess how?
