Hi Max: Great to see that live chat is back on the system.

Crusty will try to be on line.

Have at last got rid of the builders, who have engineered a new roof and cleared the window leaks.  Rain still falling but have managed to divert the water around the Mansion and stop it coming in to the rooms.

The Crusty Mansion has been redecorated and the Attic workshop has been refurbished. It seems like I might even get time to write some blogs as well.

If you do a Kickstarter for the new Arduino screw terminal board I will definitly back the effort.

Item for Live Chat (or any other time, really)

Here is something that may be interesting to some.

I have acquired a pile of Motorola EVO 4G lapdocks off Ebay recently, and I wanted to do something "cute" with them.

This project is an adapter that directly fits in the place where the EVO 4G handset would go, but breaks out the HDMI and USB connections to a Raspberry Pi.

The switching circuit part of this is so that I don't turn off the Pi by just removing the USB cable.  The Micro type B connector is the most abused in consumer electronics today.  The cute part of this is the turn-on for the pass MOSFET is very quick, but the turn-off requires a solid button press of 3 seconds.

I am using the automotive form of the dual MOSFET here as I know that people are starting to have a *lot* of extra goodness of their Pi's, and I wanted to be able to support that.

The board and schematic images are here:

Thanks for the note.  Sadly, I was not able to attend live as our project is now in beta test, and obviously things are a bit 'crunchy'.

@Maxthemagnificent Don't forget that we're recruiting participants for the third annual Gadget Smackdown! at EE Live!, one of our most popular events that tends to descend into chaous and silliness. Even before the beer.

Tell me more -- do the participants have to bring their gadgets, or will a slideshow do? How long do they get to talk for? Do you have a link for the relevant item on the EE Live! site?

Tidbits of trivia

@Max: I love the way you always introduce some tidbits of trivia in your blog posts ;-)

"A petard was a small container of gunpowder used to blow breaches in gates or walls."

In Spain, we use the word "petardo" for the little toy fireworks that looks like a tiny TNT/gunpowder barrel. When I was a child, buying some "petardos" was really easy and cheap; of course, nowadays there are a lot of laws banning this kind of "toys".
