acanalda Posted January 12, 2009 Share #1 Posted January 12, 2009 Advertisement (gone after registration) Hi to all. As you probably know (threads "Leica 1a my last chance" and "To restore or not to restore") I'm involved in a Leica 1 A restoration project. The shutter is completely destroyed and now I'm working in the new curtains. So in a few days I'll need a shutter speed tester to adjust it. Well. You can make one with a bit of patience and some common components. You need: 1 BPW40 Phototransistor. 0,13 euros 1 Resistor (between 3800 - 4200 Ohm) 1/4 w 0,04 euros 1 Capacitor (between 4100 - 5000 picofarad) 0,09 euro 1 microphone plug (mono) 0,65 euro 1 1,5 V battery holder 0,26 euro 1 1,5 V battery 0,50 euro 1 plastic case 2,59 euro 1 laser pointer (I have used one that someone gave me in a medical congress) 1 standard circuit board with holes 0,43 euro 1 switch 0,86 euro And here is the circuit scheme and some photos. I'll keep you informed about the restoration progress. Next Chapter. "The shutter restoration" Regards, Arturo Welcome, dear visitor!
