Relay Derating

I just notice that the page covering How to Derate a Relay was never listed in the blog when it was added to the web site. Looks like the page was added back in March, or at least that was the day of the first page view.

The page doesn't get that many hits, just a few a-day. I went ahead and added a new link at the top of the page covering Manufacturers of Relays. Then I did the same thing to the page covering Manufacturers of Mechanical Relays.

I also removed two manufacturers links, one looks like it went bad and the other appeared to be a relay distributor. Also added a picture of a relay.

The three pages covering relay manufacturers have dropped 50% over the last three years. Seems odd, as the relay pages come up as number 1 and 2 on a Google search for relay manufacturers....

Sony's DMP Interface

I added a new page the other day to cover the Digital Media Port [DMP] interface. The bus was developed by Sony and only resides on their gear. The page lists one possible pin out, and I don't know if there may be others. I have no other information on the interface.

Digital Media Port

The page is linked from these two pages;
Engineering Interface Buses, 'D'.
Cable and Backplane Buses.

Because this bus is only being used by Sony I may not be able to find any additional data.
