Hi! > Your capacitors were too small, try increasing their values. I was using 10uF/16v tantalum capacitors. The MAX232 was able to power even my biggest trackball using the same capacitors. ...Did you make some experiences with such a circuit, should I try for example, 100uF capacitors in my discrete voltage quadrupler? Should it increase the output current so much that it could reach 10-15 milliampers? > Another way would be to use a transformer to step-up the voltage, maybe > 1 to 3 ratio. At that low power it wouldn't have to be very big. Yes, but I want to avoid coils if it is possible. Thanks, L. - This message was sent through the cbm-hackers mailing list.
