I really wonder how long will it give light in the shown variant? (17minutes?)<br />2a. Can you recalculate the input 47Ohm Resistor and add a diode next to it - so this thing can be charged with 220v AC instead of 5V USB?<br />2b. Further more, can you replace the switch with a resistor so, when the AC power goes down, it will light automatically - like emergency light...<br /><br />regardsFireSwordhttps://www.blogger.com/profile/14529911211977416048noreply@blogger.comtag:blogger.com,1999:blog-7568228216762323778.post-74583713941652719742012-03-02T21:18:46.171+01:002012-03-02T21:18:46.171+01:00Yes - Your explanation is better!
Another though...Yes - Your explanation is better! <br /><br />Another thought, have you measured how long the 3 LEDs will run (in parallel, with a 5-ohm resistor as limiter) if you put the supercaps in series to get a 5F - 5,5v device? Then you can simplify things a lot!McHensonhttps://www.blogger.com/profile/11053107823774702768noreply@blogger.comtag:blogger.com,1999:blog-7568228216762323778.post-20825658345414063112012-02-29T08:32:40.647+01:002012-02-29T08:32:40.647+01:00Yes, Thanks for the calculation
you can say too:...Yes, Thanks for the calculation<br /><br /> you can say too:<br /><br />Joule = Watt X Seconde<br />P=UI<br />for AA NiCD battery: 2 X 1,2 X 3600 = 8640 J<br /><br />For a 10 F super cap: E=1/2 CU²= 1/2 X 10 X 2,7 X 2,7 = 36,45 J<br /><br />In my calculation, there is a ratio of 237 and in your calculation there is a ratio of 600. It is because 6000 Farad at 1,2 v is not the same thing that 6000 Farad at 2,7v.<br /><br />The only think that we can say is that in a AA battery, there is 200 times more energy than in a 10F capacitor.La Famille Créativehttps://www.blogger.com/profile/07304174651574162913noreply@blogger.comtag:blogger.com,1999:blog-7568228216762323778.post-31574329439669117032012-02-29T00:44:30.272+01:002012-02-29T00:44:30.272+01:00supersuperSistemhttps://www.blogger.com/profile/11342041144027115392noreply@blogger.comtag:blogger.com,1999:blog-7568228216762323778.post-86398368589556412612012-02-28T23:46:56.926+01:002012-02-28T23:46:56.926+01:00According to Coulomb's law;
