Raspberry pi DS?

Mon Jul 07, 2014 11:44 pm

Hi all, I want to make a small UMPC type of thing, small enough to fit in a pocket of a pair of jeans. My main problems are that I need a compact power supply, preferably with dual output sources, and I want my mini wireless keyboard to flip up and cover the screen when not in use. I made a prototype using Legos as a frame, and duct tape to hold it all together XD

If you could give me some recommendations, I'd appreciate it!

Thanks!

Power supply: http://www.adafruit.com/product/1944
Battery: http://www.adafruit.com/products/328 or http://www.adafruit.com/products/1781

You might want to splice the cable for dual output, or you can use the GPIO pins to power for the secondary output.

Not sure what I would use as an enclosure....

Right now I use my raspberry pi model B, plus a 4 port powered usb hub, plus a wifi module and a bluetooth module for my input, AND an external terabyte external hdd so that's a total of about 2amp.

Definitely not gonna use the external drive with this project, or else weight and size will be an issue, but the hub is a must because I don't think the wifi and the bluetooth dongle will work reliably on the Pi alone.....

I suggest building it from acrylic, that way you can shape it to suit your needs and maybe colour it too.

You could use this http://blog.parts-people.com/2012/12/20 ... rpi-to-go/ which gives you the files so that you can 3d print it and not worry about making it yourself. Also, it is smaller.

Awesome idea, kusti! Are there places where you can send them the blueprints, and they will print and ship it to you? I don't seem to have any businesses in my area who do 3d printing.....

If you let us know what "your area" is, people may be able to offer suitable suggestions ;)

There are a lot of places online like http://www.shapeways.com/ or http://i.materialise.com/ or http://www.sculpteo.com/en/. You can compare prices based on the models and choose which one is best. They print it out and then ship it to your door.

Thanks kusti, I will check them out later!

Very funny mrpi64....
Don't copy my work and earn millions without giving me some credit though okay?

Drew up a rough sketch of what this all will turn out to be yesterday, and was frustrated that all the ports couldn't be on one side for convenience.
Then today I go onto adafruit's website to look at batteries and power supplies, and there was the model B+

Seems like someone in the big blue sky above is looking out for me!

Anyways, I decided to use this for a screen https://www.adafruit.com/products/1928

This for the battery
http://www.adafruit.com/products/353

This for the power supply
http://www.adafruit.com/products/1944

And I will probably chop up one of these for mono sound

I'll post some pictures of my sketchings later

Are you going to de-solder/remove the massive USB, phono, USB & audio sockets? Because if you are using a phono screen, you may as well solder them together.

On the pi? No, only because if this project doesn't work out very well, I won't have to buy another pi

And what do you mean by "phono"? Never heard of the term before...

I think he means the yellow composite video connector on the Model B Pi.

Just bought 3 small sheets of lexan for the case, I'm going to cut it to shape. and I'd like to paint it but I am not sure how to paint it, I saw online that some people just used a paint pen and,some other people sanded it, primed and then painted.
