Interviews

Raspberry Pi needs no introduction. It is one of the most popular credit card sized single board computers which has become a revolution in its own right. The $25 (and $35 for B model) hardware is being used in so many fields that it’s hard to keep a tab on it.

Project aims to build “fully open” SoC and dev board

Filed under
Hardware
OSS

A non-profit company is developing an open source, 64-bit “lowRISC” SoC that will enable fully open hardware, “from the CPU core to the development board.”

University of Cambridge spinoff “lowRISC” is a not-for-profit company with a goal of making a completely open computing eco-system, including the instruction set architecture (ISA), processor silicon, and development boards. The first step is to develop a new system-on-chip design based on the new, 64-bit RISC-V ISA developed at the University of California, Berkeley.

Linux-based controller mixes Atom SoC with Kintex-7 FPGA

Filed under
Linux
Hardware

NI’s new 4-slot CompactRIO control system combines a dual-core Atom E3825 with a Kintex-7 FPGA, and features industrial temperatures and NI Real-Time Linux.

The National Instruments (NI) “CompactRIO 4-slot Performance Controller” is the high end “performance” big brother to NI’s “value” CompactRIO cRIO-9068 model, introduced a year ago. Whereas the cRIO-9068 runs NI Linux Real-Time OS on a Xilinx ARM+FPGA hybrid Zynq-7020 system-on-chip, the new CompactRIO splits processing duty between an Intel Atom processor and a higher-end Xilinx Kintex-7 325T FPGA. The CompactRIO uses a dual-core, 1.33GHz Atom E3825 SoC from the latest, 22nm Bay-Trail-I generation, featuring a relatively low, 6 Watt TDP.

Raspberry Pi-powered Bigtrak

Filed under
Hardware
Gadgets

The Raspberry Pi is a small, low-cost computer designed to promote an interest in computing and programming – but it doesn’t have to be straight-laced computing. In fact, in this article we’ll be showing you how you can use it to turn a Bigtrak into a robot. That’s educational, right?

The Bigtrak is a toy that takes in a list of straightforward commands (Go forwards, turn left, turn right) and then executes them. To make things more interesting we’re going to remove the existing circuitry and replace it with a Raspberry Pi, using a small motor driver to safely control the motors in the Bigtrak, which we’ll then set up to be controlled via a PlayStation 3 DualShock controller.

Everything required on the software side comes pre- installed on the latest Raspbian OS images, so all we need to translate changes from the controller to the motors is a small Python script that uses the Pygame and RPI.GPIO modules.

Hardware

Storm Energy has upgraded its “SunSniffer” solar plant monitoring system to a Linux-based platform running on a Raspberry Pi SBC.

Germany-based Storm Energy is the latest of a growing number of companies building commercial products based on the hackable Raspberry Pi single board computer. The company’s SunSniffer system is designed to monitor photovoltaic (PV) solar power installations of all sizes, and the latest version can also control the equipment, says the company. The new SunSniffer version adds a Raspberry Pi SBC along with a custom expansion board and customized Linux OS, which combine to enhance the system’s flexibility and upgradability.

Hardware

Samuel Pitoiset continues making steady, great progress on his Google Summer of Code project as a student developer reverse-engineering and implementing NVIDIA hardware performance counters within the open-source Nouveau driver.

For months now he's had a solid understanding of how NVIDIA's performance counters operate and has been working towards exposing them in a NVPerfKit-like open-source manner and exposing them to OpenGL developers. Samuel's latest update revealed his MP counter work was up to a prototype stage while today he has a new blog post concerning the approaches to exposing the performance counters in Nouveau.

Raspberry Pi add-on board controls entire buildings

Hardware

UniPi is seeking Indiegogo funding for a Raspberry Pi add-on for building automation with analog and digital I/O, changeover relays, and 1-Wire interfaces.

The Raspberry Pi has found its way into many a home automation project, from lighting controls to automatic sprinkler systems, and is often used as a prototype for commercial systems. But is the modest RPi up for managing an entire building? No problem, says Czech startup UniPi, which is offering Indiegogo funding packages of 99 Euros ($133) and 109 Euros ($146) for its UniPi building automation add-on board.
