We all the time get excited once we purchase a brand new pill. However after just a few months, it normally winds up on the backside of a pile of papers on the credenza, a sufferer of not being as highly effective as our desktop computer systems and never being as handy as our telephones. Nonetheless, in the event you don’t thoughts a thick pill, you may get the RasPad enclosure to suit round your personal Raspberry Pi so it may be used as a pill. Actually, we weren’t that impressed till we noticed [RTL-SDR] add an SDR dongle inside the case, making it a really moveable Raspberry Pi SDR platform.
The field is somewhat fascinating by itself, though be warned it prices over $200. For that worth you get an LCD and driver board, a battery system, audio system, and an SD extension slot with some management buttons for quantity and brightness. There’s a video of the entire setup (in German) under.
The entire affair weighs about 1 kg, a bit heavy for a pill. It is usually pretty thick though that’s good for making this type of modification and likewise provides the contact display a pleasant angle when it's flat on a desk.
Most Raspberry Pi software program isn’t setup for a touchscreen, however the publish explains a number of the points they discovered when utilizing a special Linux construct as a substitute of the default pill software program from the maker of the case.
We nervous that the SDR contained in the case could be topic to interference, however apparently, with an exterior antenna, it was negligible. You can see the interference when utilizing an antenna hooked up on to the field via the added RF connector, although. Your outcomes could possibly be worse in the event you used an SDR dongle with out correct shielding, too.
