I’m very excited about this project and the possibilities it enables, and I hope you are excited about it was well.”

Funding ends on Dec 09, 2020 at 03:59 PM PST (11:59 PM UTC). Visit the Crowdsupply campaign page for more information.

Network Traffic Visualizer

Posted on by Micael Coutinho

Have you ever wanted an indicator of how much the internet is being used at a particular time? You may want to know if your roomies are making it too slow for you to use, or just for the sole purpose of fun. For some reason, the router manufacturers usually do not include an indicator as such, but you do not need to be sad now. Because we are makers, we will make one! Or at least that was what Chandler McCowan from Hackster thought when creating a network traffic visualizer.

How would you make such a device? Easly, a packet sniffer! Hold up, calm yourself down, a packet sniffer is not the most legal thing to do, so we are not encouraging that sort of behavior (but seriously, if you can decrypt those packets, you are a god to me). With something similar to the likes of a packet forwarder, you can inspect the network and count how many packets are going through it. Seems difficult, but in reality, it is not. You can do such a thing with raw sockets, in an afternoon. It is a very good exercise if your goal is to understand the inner workings of the internet in practice, with UDP and TCP, and even go a bit beyond that.

Now, to the nitty-gritty of this project, Chandler made use of an ESP8266 and created a neat PCB to go along with it, housing 8 LEDs and a shift register to control them. Besides that, you get the necessary connectors to program the ESP board, so if you want to make changes to give it more functionalities or even use the kit in another different setting, you can, easily. Unfortunately, the kit does not allow you to be too creative, as there is no space to connect sensors or other peripherals, as most of the GPIO pins are occupied by the LED driver. On the flipside, it is designed to do one thing and does it well. You get a portable Wi-Fi “VU meter”. There is also an interesting 3D printed stand. But even if you feel underwhelmed by the project (which you should not, as it’s sole intend and purpose is to visualize the network), you can use it as a starting point and change it to your liking, as everything is open source: from the PCB schematic and files to the 3D printed stand and the Arduino code, you can access everything.

Lastly, this is still a work in progress, as there is a website currently under development that will provide all the information on this nifty project. While you wait, you can order it on Tindie for $15, which is a reasonable price for a finished product.

New Raspberry Pi 400 sells for $70 and is a computer in a compact keyboard

Posted on by Emmanuel Odunlade

Raspberry Pi, whose mission is to put “affordable, high-performance, programmable computers into the hands of people all over the world”, has unveiled Raspberry Pi 400 which is a complete personal computer built into a compact keyboard.

“We’ve never been shy about borrowing a good idea. Which brings us to Raspberry Pi 400: it’s a faster, cooler 4GB Raspberry Pi 4, integrated into a compact keyboard”,

says Eben Upton, founder and CEO of Raspberry Pi.

Since more children are likely going to be dependent on remote learning in the coming months and more people working from home, the Raspberry Pi 400 might just be that affordable solution to many, especially students who are in need of a personal computer. It starts at a price that is a lot cheaper than some of the most budget phones and comes with a keyboard that’s big enough for proper writing. Just plug it into a monitor or a TV using any of its two micro HDMI ports, insert a microSD card, and attach a power cord and a mouse.

The Raspberry Pi 400 shares almost the same computer features as the Raspberry Pi 4, but with a little difference. The Raspberry Pi 400’s quad-core Cortex-A72 (Arm v8) 64-bit SoC runs at 1.8GHz while the Raspberry Pi 4’s SoC runs at 1.5GHz. The Pi 400 also offers only HDMI for audio output while the Raspberry Pi 4 has a 3.5mm audio and video jack.

Features and Specifications of the Raspberry Pi 400 include: 

  • CPU: 64-bit Broadcom BCM2711C0 quad-core ARM Cortex-A72 processor running at 1.8GHz
  • 4GB RAM
  • 1x microSD card slot
  • 2x USB 3.0, 1x USB 2.0 and 1x USB Type-C ports
  • 2x micro HDMI support dual display
  • Gigabit Ethernet
  • IEEE 802.11 b/g/n/ac WiFi (2.4GHz + 5GHz & Shielded)
  • Bluetooth 5.0 + Bluetooth Low Energy
  • 1x PCB antenna
  • Horizontal 40-pin GPIO header (right angle)
  • 2x micro HDMI ports
  • 1x built-in power button, and
  • Built-in Heat sink
  • Power Input: 5V via USB Type-C (up to 3A)
  • Dimensions: 285mm x 122mm x 21mm
  • Operating temperature: 0°C to +50°C

The Raspberry Pi 400 comes with its own OS but can be made to run a version of Windows. It is available and sells for $70 as a standalone machine or $100 as a ready-to-go kit that includes a mouse, USB-C power supply, microSD card, micro HDMI cable, and Raspberry Pi beginner’s guide. Hopefully, before the first half of next year, the Raspberry Pi 400 should be readily available around the world.

Raspberry Pi Compute Module 4 Goes up For Sale Starting From $25

Posted on by Tope Oluyemi

The Raspberry Pi Foundation has launched the Raspberry Pi Compute Module 4 (CM4)  starting at $25 price and offers up to 8GB RAM, Broadcom BCM2711 SoC with 4x 1.5GHz Cortex-A72 cores found on the RPi 4. The Compute Module 4 is built on the same 64-bit quad-core BCM2711 application processor as Raspberry Pi 4. However, the Compute Module 4 “delivers a step-change in performance over its predecessors: faster CPU cores, better multimedia, more interfacing capabilities, and, for the first time, a choice of RAM densities and a wireless connectivity option.” The Compute Module 4 also features LPDDR4-3200 RAM, but it’s the first with a GbE controller and the first with optional wireless. You can get 802.11b/g/n/ac and Bluetooth 5.0 BLE plus an optional external antenna for $5.

The Compute Module 4 features a brand new form factor and a compatibility break with earlier Compute Modules. It substitutes the SODIMM connector of the CM3+, CM3, and original Arm11-based CM1 to dual, high-density, 100-pin perpendicular connectors — one for power and low-speed interfaces found on the CM3/CM3+ and one for high-speed interfaces like PCIe. This significantly reduces the overall footprint of the module to a smaller 55 x 40 x 4.7mm footprint on its carrier board, enabling you to achieve smaller form factors for your products. Raspberry Pi Foundation is launching the CM4 in 32 variants, with four RAM options, four Flash options, and optional wireless connectivity. Prices range from $25 (for the 1GB RAM, Lite, no wireless variant) to $90 (for the 8GB RAM, 32GB Flash, wireless variant). Also, the four variants with 1GB RAM and no wireless keep the same price points ($25, $30, $35, and $40) as their Compute Module 3+ equivalents:

“once again, we’ve managed to pack a lot more performance into the platform without increasing the price.”

Compute Module 4 IO Board

Raspberry Pi Foundation is also launching an updated IO Board to help you get started with the Compute Module 4. Like the IO boards for earlier Compute Module products, this breaks out all the interfaces from the Compute Module to standard connectors, providing a ready-made development platform and a starting point for your own designs. The IO board features two full-size HDMI port, Gigabit Ethernet jack, two USB 2.0 ports, and MicroSD card socket (only for use with Lite, no-eMMC Compute Module 4 variants). It also enables x1 socket PCI Express Gen 2, HAT footprint with 40-pin GPIO connector and PoE header, 12V input via barrel jack (supports up to 26V if PCIe unused), Camera and display FPC connectors, and Real-time clock with battery backup. CAD for the IO board is available in KiCad format.

Antenna Kit and Compute Module 4

Available also is an optional, $5 Compute Module 4 Antenna Kit for situations where there’s a metal case that might block the internal antenna, or where it is not possible to provide the necessary ground plane cut-out under the module. The kit comes with a whip antenna with a bulkhead screw fixture and a U.FL connector. The highlight of the spec list includes:

  • 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU
  • VideoCore VI graphics, supporting OpenGL ES 3.x
  • 4Kp60 hardware decode of H.265 (HEVC) video
  • 1080p60 hardware decode, and 1080p30 hardware encode of H.264 (AVC) video
  • Dual HDMI interfaces, at resolutions up to 4K
  • Single-lane PCI Express 2.0 interface
  • Dual MIPI DSI display, and dual MIPI CSI-2 camera interfaces
  • 1GB, 2GB, 4GB or 8GB LPDDR4-3200 SDRAM
  • Optional 8GB, 16GB or 32GB eMMC Flash storage
  • Optional 2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0
  • Gigabit Ethernet PHY with IEEE 1588 support
  • 28 GPIO pins, with up to 6 × UART, 6 × I2C and 5 × SPI

The Raspberry Pi Compute Module 4 is available now ranging from $25 to $90. You can also check CanaKit for the SKU. The IO Board costs $35 without a CM4 module. You can find more information on the Raspberry Pi Blog announcement and CM4 product page for shopping and additional documentation.
