Re: Interface w/ RFM69W wireless module via SPI?

The moteino is certainly a nice piece of hardware, but it does not answer the question of this topic. You now would need to interface between moteino and pi (which you could do using SPI as well), which brings up all the same questions: How to electrically connect them, what commands to use, bufferi...

Re: Interface w/ RFM69W wireless module via SPI?

That board changes nothing to the (electrical and software) interface. It does make it easy to stick the board onto a breadboard. Combined with an adapter like this it can make your experimental setup easy on the eyes en thus prevent errors. The breakout board itself can not be plugged onto the Pi d...

Re: A rather different sort of enclosure idea

One could make 2 solid halves using a mold slightly bigger than the Pi and screw the 2 halves together with a Pi in between.

The biggest problem will be that the Pi has connectors on all sides near the edge of the board. (where would you place the screws?)

Re: A basic acrylic enclosure for developers

You could make a slit into the busses and stick the corners of the Pi into them. Or use a smal bus, a large bus and a thick washer with a square files out in between. (I hope I've made myself clear, or should I make a drawing?)

This would make the vertical plexiglass stands obsolete.

Re: Straw poll for home print cardboard case: What printer do you have?

I can print on CD's using a special tray.

A CD is probably not big enough to make a case in one go, but 2 interlocking U-shaped pieces will probably do nicely.

I challenge you to make a case out of CD's That would make one creative case (DVD's are also acceptable)
