2015-01-18 Portable Cell Phone Chargers

My friend has been living with an old flip-phone with a crack in the still readable screen and just basic phone service, so I thought it would be good to get him a used phone, but something a few generations newer.  I got a used Samsung Zeal, which is (I call it) a flip-flop phone.

2014-12-31 Almost New Years – Phone Problem

December 30, and about 25 hours before a new year.  I should change all my smoke alarm batteries. Since I’ve had my Samsung Galaxy S4 phone, I have had trouble with the phone touchpad during making or receiving phone calls. Soon after I got it a year and a half ago I got a Body

2014-12-30 The Day Before New Year

December 30, and about 25 hours before a new year.  I should change all my smoke alarm batteries. I was watching This Old House recently and the electrician installed new outlets in a very old house that had a gas chandelier that had been converted to electric lights. He showed how the new work had

2014-12-12 I Setup A New Samsung TV

My ‘old’ TV was a Samsung 40 inch I got 1 year ago.  I should have remembered how many problems I had last year when I set it up.  This new Samsung 46 inch is just as bad, if not worse. I do not want to setup the TV by having it search for all

2014-12-04 RF Interference From DC-DC Converter

I’ve been using these DC-DC converters for charging cell phones in my car and in the house (more in this blog) and they work fine.  But when I plug my phone in, my FM radio station gets a lot of RF interference.  I admit that the station, KSBR, which is low power and far away,

2014-08-05 Joule Thief Design Ideas

Here is a guy’s photo collection of his Joule Thief artistic designs on Flickr.  He’s come up with some innovative results using various items of plastic, wire and glue to give some cool looking JT lights.  I think this T. Rex might also be used for a note holder or perhaps a third hand for

2014-05-04 UV LED Flashlight

I bought some ultraviolet flashlights for about $5 apiece from Goldmine Electronics.  These are the same as the standard 9 white LED flashlights that are found in the bargain stores except for one additional feature which is and on off switch next to the head.  Normally the on/off switch is on the rear of the

2014-04-17 Not A Printed Circuit Board

I have thought about this a few times in the past.  It may be more environmentally friendly than using copper or other metals for a circuit board. I have some small scraps of wood that I think would make a good circuit board for a project.  Some Hams (amateur radio operators) have used the Manhattan

2014-04-13 Samsung Galaxy S4 Problems

For the last month or so GS 4 has been a bit of a problem.  First started requiring charging twice a day.  I was thinking that it was because I used it a lot more.  That may be one reason but I think now that its about 8 months old the battery is losing a

2014-01-14 Watson’s Standardized Joule Thief

I found this picture that I had posted to my late, great watsonseblog.blogspot.com.  I have added my new rustybolt.info/wordpress blog address to it. This is a Joule Thief that uses standard parts, including a readily available toroid core.  This high permeability core can be wound with various sizes of wire, but about ten turns will
