Notícias fresquinhas da silva, cortesia da DesignSpark, eis que aparece um novo Modelo de Paspberry pi!



Raspberry Pi Model A

Pete Wood

This week I received an early Christmas present from Eben at the Raspberry Pi Foundation.  Thanks Eben! I'm very lucky to get my hands on a pre-production Raspberry Pi Model A and will be putting it to good use! 
Scheduled to be on sale at RS Components mid Jan/early Feb 2013*, the Model A is the latest offering from the Raspberry Pi Foundation,  Offered at a $25 price point**.  The Model A is basically a stripped down version of the current shipping Model B.  The main difference between the two is that the Model A has no MagJack and Ethernet Phy, a single USB port and 256MB of SDRAM.








Para um Detector de Radiações low cost, eis uma Câmara de Ionozação!

An Ionisation Chamber Shield for OpenRelief

Andrew Back

Back in May I wrote about a low cost radiation detector I was prototyping for the OpenRelief project. Based on a simple ionisation chamber, initial testing used a bank of batteries for the bias power supply and this post details the construction of an inverter to replace these.
For details of the detector itself see the original post as none of the fundamental details have changed, and for more on OpenRelief see the interview with project leader, Shane Coughlan.
