Devices: Spectrogram and Boards With (Optional) Linux

Filed under
Hardware
  • Spectrogram Drawing For Fun And Coding | Hackaday

    The code is a bit slow so writes its values to a file which is output by a HackRF, but it could just as easily be used by any other capable output device such as GNU Radio and a soundcard if you too want an Aphex Twin moment.

  • Fanless Coffee Lake computer targets testing and analysis

    No OS support was listed for the Neu-X302, but the Neu-X300 runs Linux or Win 10. The new Coffee Lake Refresh options range up to the octa-core, 1.8GHz/2.2GHz Core i7-9100TE with 35W TDP. Once again, there is a choice of Intel Q370 or Intel H310 I/O chipsets, creating two SKUs. However, there are fewer feature differences.

  • Arm-based IoT gateway reaches out with WiFi, Bluetooth, LTE, and NB-IoT

    Aaeon’s compact “SRG-3352C” IoT gateway is equipped with a TI AM3352, 3x USB, 2x RS-485, 2x GbE, WiFi/BT, mini-PCIe with micro-SIM, and an NB-IoT connector.

    It’s always a bit troubling when vendors omit the name of an embedded system’s processor. However, Aaeon’s fanless SRG-3352C Compact Edge IoT Gateway System, which is said to be based on an 800MHz, Cortex-A8 SoC, gives away the mystery in its name: the IoT gateway no doubt features the aging TI Sitara AM3352. No OS support was listed but given the AM3352 — the lowest end model in the AM335x line, with no 3D GPU or PRU-ICSS cores — Linux is almost certainly supported.

  • Embedded Artists launches 1GHz NXP i.MX RT1176 Crossover MCU module and devkit

    Anders Rosvall, CTO at Embedded Artists AB, explains the i.MX RT1176 uCOM board “enables customers to move up to application-level performance without having to move to the Linux world”, and provides an update from the company’s iMX RT1064 uCOM with double the SDRAM, MIPI-DSI interface, and a 2D graphics engine. In case you wonder why a company would not want to move their application to a Linux platform, reasons include code reuse, faster real-time responsiveness, and lower power consumption.

  • Cortex-A7 module debuts with optional Pico-ITX carrier

    DH unveiled a “DHCOM STM32MP1” module that runs Linux on ST’s Cortex-A7/M4 SoC with up to 1GB RAM, 16GB eMMC, and WiFi/BT. “DH PicoITX2” and “DH PDK” carriers are also available.

How I digitized my CD collection with open source tools

The restrictions on getting out and about during the pandemic occasionally remind me that time is slipping by—although some days, "slipping" doesn't quite feel like the right word. But it also reminds me there are more than a few tasks around the house that can be great for restoring the sense of accomplishment that so many of us have missed. One such task, in my home anyway, is converting our CD collection to FLAC and storing the files on our music server's hard drive. Considering we don't have a huge collection (at least, by some people's standards), I'm surprised we still have so many CDs awaiting conversion—even excluding all the ones that fail to impress and therefore don't merit the effort.

Hyperbola Linux Review: Systemd-Free Arch With Linux-libre Kernel

In the last month of 2019, the Hyperbola project took a major decision of ditching Linux in favor of OpenBSD. We also had a chat with Hyperbola co-founder Andre Silva, who detailed the reason for dropping Hyperbola OS and starting a new HyperbolaBSD. HyperbolaBSD is still under development and its alpha release will be ready by September 2021 for initial testing. The current Hyperbola GNU/Linux-libre v0.3.1 Milky Way will be supported until the legacy Linux-libre kernel reaches the end of life in 2022. I thought of giving it a try before it goes away and switches to BSD completely. Read more
