Raspberry Pi 4 Model B
Here are the highlights:
- A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
- 1GB, 2GB, or 4GB of LPDDR4 SDRAM
- Full-throughput Gigabit Ethernet
- Dual-band 802.11ac wireless networking
- Bluetooth 5.0
- Two USB 3.0 and two USB 2.0 ports
- Dual monitor support, at resolutions up to 4K
- VideoCore VI graphics, supporting OpenGL ES 3.x
- 4Kp60 hardware decode of HEVC video
- Complete compatibility with earlier Raspberry Pi products
The Astro Pi board is a Raspberry Pi HAT and will comprise the following:
- Gyroscope, accelerometer and magnetometer sensor
- Temperature sensor
- Barometric pressure sensor
- Humidity sensor
- Real time clock with backup battery
- 8×8 RGB LED display
- Several push buttons
It will also be equipped with both camera module and an infra-red camera.
During his mission Tim Peake will deploy the Astro Pis, upload the winning code whilst in orbit, set them running, collect the data generated and then download it to be distributed to the winning teams.
Organizations typically focus on monitoring inbound and outbound network traffic via firewalls, yet ignore internal network traffic due to the complexity involved. In the scenario above, a firewall will not protect or alert us.
By running honeypots on our internal network, we are able to detect anomalous events. We gain awareness and insight into our network when network hosts interact with a Raspberry Pi honeypot sensor. Since there isn’t a good reason to interact with it (since it doesn’t do anything), activity on the Raspberry Pi is usually indicative of something roaming around our network and a possible security breach.
As an end user, the process of using the oRouter is designed to be exceedingly simple. It’s zero configuration, meaning that you plug it in and then connect to the Wi-Fi network it provides. Unlike the Tor download, it requires no additional software in order to work. Once connected, as you browse the web and use online services, you’re actually using Tor (via Wi-Fi), thereby securing your communications from eavesdropping. In addition, for an extra layer of security, the oRouter’s MAC address (hardware address) changes every 10 minutes.
The User interface allows you to:
- position the dolly on the rail via the motor control buttons
- change the motor pulse duration between shots
- change the delay between shots
- change the number of shots
- see what time is left for the current sequence
- start and stop the time-lapse
And it’s all done using a few simple screens with a simplistic, easy-to-use touchscreen user interface. The following video shows it all in action.
The Utilite can have the processor configured up to 1.2GHz, up to 4GB of DDR3 RAM, up to a 512GB mSATA SSD, up to a 128GB Micro-SD SDXC, and two display ports — HDMI 1.4 and DVI-D — up to 1920×1200 resolution at 60Hz. The specs of the GPU aren’t listed, but rather what is listed is what it supports: OpenGL ES 1.1 and 2.0, OpenVG 1.1 and OpenCL EP, multi-stream 1080p H.264, VC1, RV10, and DivX HW decoding. What seems static on the Utilite, at least, is Bluetooth 3.0, two Gigabit Ethernet ports, 802.11b/g/n WiFi, stereo line-out and in, four USB 2.0 ports, a micro-USB OTG connector, and two RS232 serial ports.
The MinnowBoard Max will go on sale early in the third quarter. Two versions will be offered initially: a $99 entry-level model, with a 1.46GHz single-core E3815 SoC and 1GB RAM; and a $129 model, equipped with a 1.33GHz dual-core E3825 SoC and 2GB RAM. Additional details will soon be available at Minnowboard.org as well as at CircuitCo’s MinnowBoard product page.
The regular install on a Raspberry Pi is NOOBS (new out-of-box software) and contains several pre-packaged operating systems. However for the purpose of our MITM device we’ll be using a different Linux distro for our Pi: PwnPi. PwnPi is a distribution of the Raspbian OS that contains many pre-installed packages for security and penetration testing which is naturally right up our alley. So, go ahead and download PwnPi. Once it’s downloaded we’ll need to load it onto our SD card. First, format your SD card using the SD card formatter from the SD association. If the “size” value shown in the formatter is less than the size of your card, be sure to choose “format size adjustment” in the card.
I’d been working on a PiFace interface so I could use my Raspberry Pi without a keyboard and monitor. For a bit of fun I wondered if I could turn it into a simple digital camera, that would take a picture when a button was pressed, and to my pleasant surprise, discovered you could. An idea was beginning to form in my head. If I wrote a bit more code, instead of pressing a button to take a picture, I could trigger it remotely over a network. Furthermore, it cost a lot less than any other digital camera. Could the Raspberry Pi really recreate a bullet time style effect?
To everyone’s amazement, including mine, it actually worked! Raspberry Pi had frozen time, recreating a Hollywood effect for a fraction of the cost. You can see the results in the video above http://youtu.be/IqoA4HeBCQ4?t=2m19s
One thing these platforms have in common is an ARM processor. Now they have some competition from Intel with its “MinnowBoard,” a $199 computer in the form of a 4.2″ x 4.2″ board with an Intel Atom processor.
MinnowBoard uses a 5V/2.5A power supply. Other specs are as follows:
- Intel Atom E640 CPU (1.0GHz, 32-bit with Hyper-threading and Virtualization Technology)
- Integrated Intel Graphics Media Accelerator (GMA) 600
- PCI Express
- SATA2 3Gbps
- Gigabit Ethernet
- UEFI Firmware
- 1GB DDR2 RAM<
- 8 GPIO pins
- 2 GPIO-controlled LEDs
- 4 GPIO switches
