  • Cucumber ESP32-S2 Development Board Comes with USB OTG Port, Optional Sensors

    Yesterday, I wrote about LilyGO TTGO ESP32-S2 WiFi IoT board, but one commenter mentioned it missed one of the key features of ESP32-S2 chip: a USB OTG port. While USB OTG is accessible through the header pins, it’s not the most convenient to use.

    I also quickly mentioned Cucumber ESP32-S2 development board in that post, but I did not expand too much since I thought it should only ship within Thailand. But the board does include two USB Type-C ports, one for the usual USB UART connector, and the other for USB OTG, and I found out the board is available worldwide.

  • TTGO ESP32-S2 WiFi IoT Board Comes with Optional MicroSD Card and Battery Support

    All ESP32-S2 boards I’ve seen so far were from Espressif Systems themselves including ESP32-S2-Saola-1 and ESP32-S2-Kaluga-1, but LilyGO TTGO ESP32-S2 is the first third-party board for sale so far.

    The tiny board is somewhat similar to ESP32-S2-Saola-1 board and comes in two versions with a similar form factor, but a completely different pinout and the presence of a MicroSD card socket and a battery connector on one of the boards.

    [...]

    The boards are a bit more different than I expected at first look. Please note that specifications should be seen as preliminary, as there were obvious mistakes such as Bluetooth support (not available for ESP32-S2) which I did not included in the specs above, but there may be others which I missed.

  • Open Source Ventilators Helped by Electronic Design Software

    In the early days of the pandemic, the first major challenge facing nations was a shortage of personal protective equipment (PPE) and ventilators. The former helps safeguard hospital personnel from potential contamination; the latter are necessary to keep the most critically ill patients breathing once the virus attacks their respiratory systems.

    Ventilators are traditionally large and very costly devices; smaller ventilators—known as field emergency ventilators (FEVs) have been used in emergency settings, including combat missions and in Third World nations for decades to help keep patients alive as they await transport to hospitals for intubation.

  • NASA JPL Team Fires up Open Source PPE Respirator Designs

    Does it really take a team of rocket scientists to rapidly engineer a top-notch line of personal protective equipment (PPE) to protect against COVID-19 spread? And then to open source its production designs for the benefit of anyone with access to a 3D printer?

    The answer: not necessarily, but it sure can help.

    That’s the latest good news on the pandemic front from the technology and innovation team at the National Aeronautics and Space Administration’s (NASA) Jet Propulsion Laboratory (JPL).

  • NASA and other innovators work to redesign ventilators for Covid-19 patients

    NASA scientists as well as other innovators are busy developing alternatives to the traditional ventilator being used worldwide to treat severe cases of Covid-19. The movement is in response to growing evidence that in some cases ventilators can cause more harm than good in some patients with low oxygen levels. Statistics tell the story: 80% of patients with the coronavirus die on such machines.

    This comes just a few months since the early days of the coronavirus pandemic, when U.S. healthcare providers said that they needed ventilators to accommodate the flood of new patients, and lots of them. The crisis triggered the Trump administration to activate the Defense Production Act so manufacturers including Ford, GM and GE could start ventilator production to produce these medical devices for the U.S. government.

Hardware: Arduino Nano, Advantech and Adafruit

  • Clockception combines 24 clocks to create one clock

    What if you were to use the hands of a clock not as an individual display, but as part of an array combines together to form digits? That’s the idea behind Clockception by creator “Made by Morgan,” which utilizes 48 servo motors to drive 24 clock-like faces for an 8×3 display. The build uses an Arduino Nano and three servo driver boards to control movement, along with a DS1302 RTC module to track time. The overall clock is constructed out of stained poplar, while the dial assemblies are 3D-printed.

  • Change the volume of any app on your PC with the turn of a knob

    Overall computer volume control is important, but what if you want to get more granular, adjusting sound from various applications individually? Rather than going through a series of menus and on-screen sliders, Ruben Henares’ Maxmix lets you do this on the fly. Based on an Arduino Nano, the simple yet stylish knob takes input from an encoder and button to cycle through and select a program. Just push down and then rotate to turn the volume up or down.

  • Atom C3000 net appliance offers options for 10GbE, PoE, WiFi 6, and 5G

    Advantech’s fanless, -20 to 70°C tolerant “FWA-1112VC” net appliance runs Linux on an Atom C3000 with 6x GbE or 4x GbE with 2x 10GbE SFP+ ports along with optional PoE and 3x M.2 for SATA, WiFi 6, and 4G/5G. Advantech has announced a highly customizable, IP40-protected desktop networking system with extended temperature support. The FWA-1112VC is described in the Electropages story where we found out about it as the latest in the company’s “entry and mid-level white boxes for SD-WAN and uCPE.”

  • QuickFeather Board is Powered by QuickLogic EOS S3 Cortex-M4F MCU with embedded FPGA (Crowdfunding)

    Yesterday, I wrote about what I felt what a pretty unique board: Evo M51 board following Adafruit Feather form factor, and equipped with an Atmel SAMD51 Cortex-M4F MCU and an Intel MAX 10 FPGA. But less than 24 hours later, I’ve come across another Adafruit Feather-sized Cortex-M4F board with FPGA fabric. But instead of using a two-chip solution, QuickLogic QuickFeather board leverages the company’s EOS S3 SoC with a low-power Cortex-M4F core and embedded FPGA fabric.

"ATGC" Aims To Offer Greater Garbage Collection Efficiency For F2FS

F2FS as the Flash-Friendly File-System for Linux continues to see a lot of interesting developments for this file-system beginning to appear on more Android devices and elsewhere given its feature set from flash optimizations to native encryption and compression capabilities. The newest F2FS feature work worth mentioning is support for age-threshold based garbage collection (ATGC). This ATGC garbage collection is geared to improve the efficiency and effectiveness of the background garbage collection for the file-system by evaluating older candidates first based on a defined age threshold.

GNUnet 0.13.0 released

We are pleased to announce the release of GNUnet 0.13.0. This is a new major release. It breaks protocol compatibility with the 0.12.x versions. Please be aware that Git master is thus henceforth INCOMPATIBLE with the 0.12.x GNUnet network, and interactions between old and new peers will result in signature verification failures. 0.12.x peers will NOT be able to communicate with Git master or 0.13.x peers. In terms of usability, users should be aware that there are still a large number of known open issues in particular with respect to ease of use, but also some critical privacy issues especially for mobile users. Also, the nascent network is tiny and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.13.0 release is still only suitable for early adopters with some reasonable pain tolerance.
