My co-worker asked me to do some soldering for him. He had a micro USB cable that he wanted to convert to an OTG cable. I didn’t know what an OTG cable was, but he told me that all I had to do was connect the pin five to ground on the micro USB connector.

Last year I experimented with the exciter that I saw on a Youtube video. It’s a simple circuit, and does some eery things, like light up a nearby CFL without any connection. The picture shows the schematic and how simple it is to implement.
I’ve built an automatic shutoff timer into a regular flashlight, and into my Commercial Killer. Putting a timer into a JT has a very practical use: it saves the battery. I’m not sure why someone else hasn’t tried to do it, maybe just never occurred to them. I thought about putting one into a JT

I think this picture and schematic was posted to my watsonseblog. but it didn’t get posted to this rustybolt.info/wordpress/ blog. It’s a picture of my SJT Flasher with the parts labeled, and a schematic of same.
I came across and article in an old electronics magazine on how to make a directional microphone with a cardboard horn. I decided to copy the horn part. The horn consists of four triangle shaped pieced of cardboard cut from boxes. Each of the four pieces is 1 inch (25.4mm) at the small end, 12

Peter sent me a picture of his Bedini motor, with its colorful coil (see the attached picture). He says it draws 30 milliamps at 9V when running at maximum speed. There seems to be a large following of this Bedini SSG device, especially among the Free Energy advocates. It is called Bedini SSG, for Simplified

Something is seriously wrong with legislators who take such a radical view of the laws. This article tells us that some members of congress are trying to repeal a law that is supposed to reduce the use of electricity and save consumers a lot of money. I think that this is another indication that the
