Dropping 1V from a Regulated 6V Wall Wart
"Watson A.Name - Watt Sun, Dark Remover" wrote in message m... In article , mentioned... [snip] I did this a while back. Replaced the 7806 in the wall wart with a 7805. Wade Yeah, but I've got four or five of them and I didn't want to crack them open and then have to deal with the hassles of a case that's no longer solidly sealed. And besides, they were only two bucks apiece. I may bave paid more for their shipping. Also, I bot four of the 6VDC unregulated wall warts at the same time, and they have about 7 or 8V output unloaded. I don't think they have enough voltage to allow a 7805 to work properly, at least not up to 200 mA, because the DC voltage drops down to near 6V at that current. But 6VDC is a convenient value, used by a lot of equipment that has four AA cells. So I have them just in case I want to 'electrify' one of those ol' radios or whatever. You can get low dropout regulators that will give you a stable 5v from a 6v input, they're just less common. |

One more try though: from http://www.jimprice.com/jim-asc.htm , link to "Decimal to Ascii Chart". it's 234 I didn't type the zero because it didn't say to O 234 ê 0234 023 does nothing { 123 ? 321 ? 0321 If you gave a monkey a typewriter...

Dropping 1V from a Regulated 6V Wall Wart

Remover" said... In article , mentioned... [snip] I did this a while back. Replaced the 7806 in the wall wart with a 7805. Wade Yeah, but I've got four or five of them and I didn't want to crack them open and then have to deal with the hassles of a case that's no longer solidly sealed. Try JB weld. It's been used on radiators, engine blocks, IIRC it resists gasoline. I've used it for small auto body patches - it can be filed, Shurformed, and sanded. Other epoxies would work just as well. And besides, they were only two bucks apiece. I may bave paid more for their shipping. LOL. You'll pay $5-$6 for the JB Weld at the hardware store. The shipping kills me sometimes, though. Min S&H charge for a $2 item when you can place a $30 order for the same S&H. Also, I bot four of the 6VDC unregulated wall warts at the same time, and they have about 7 or 8V output unloaded.
