Don't get us wrong, we love our Raspberry Pi. But if you're merely running a Linux image without adding a hardware hack into the mix you're missing out on part of the power for which the platform was developed.
If your 512MB Pi has a Hynix memory chip in the middle of the board (that’s the black, square RAM chip right in the centre, and it’ll either say Samsung or Hynix on it in white letters), please ensure you are using the latest version of Raspbian, which you can get from the downloads link at the top of the page.
Liz: We're very close to being able to release the $25 add-on camera board for the Raspberry Pi now. David Plowman has been doing a lot of the work on imaging and tuning. He's very kindly agreed to write a couple of guest ...
Want to build your own computer using the super cheap guts provided by Raspberry Pi but don't know where to start? Ever wanted to work in a customized operating system you know like the back of your hand?
RFduino: A finger-tip sized, Arduino compatible, wireless enabled microcontroller, low cost enough to leave in all of your projects! (Hey @wolfwithdances @awesomesprout, et. al: Relevant to your interests?
MEBM stands for: Mouse's Ethernet Based Messaging, and is a super-simple protocol for sending messages between Arduinos over Ethernet based TCP/IP (i.e. Arduino devices with Ethernet shields on them, the integrated Arduino Ethernet board, Nanode and so on).
Each Arduino sends and receives MEBM Protocol messages using the Mebm object, which implements methods for constructing correctly formatted messages, sending them, and handling incoming messages.
Yesterday’s post was about plotting the response of a decoupling capacitor versus frequency. It might not seem like much, but this is in effect exactly what a Spectrum Analyser with “Tracking Generator” does! You put a signal with a known frequency and amplitude into a circuit, and you look at the amplitude of the signal that comes out
This is the continuation of yesterday’s post about decoupling capacitors. As promised, some more information now about a test setup which can visualise some interesting – and quite surprising – effects.
