Bluetooth battery tester also serves as DC programmable load

18650 battery testing

While it’s possible to quickly check a battery with a multimeter, the DL24MP-150W Bluetooth battery tester and DC programmable load allows testing of all sorts of batteries from a 18650 battery to a lead-acid car battery, monitoring of multiple parameters with voltage, current, power, capacity, temperature, and more, and simulating a discharge. You can visualize the parameters on the integrated color display, or through Bluetooth connectivity, check out the parameters and history in an Android smartphone or a PC running Windows. The program also shows additional parameters like estimated CO2 emissions and electricity charge, plus export of parameters to a spreadsheet for further analysis. DL24MP-150W Bluetooth battery tester specifications: Test voltage – 2 to 200V Current: 0.2~20A Discharge power – Up to 150 W Sensor – Temperature sensor Adapter boards Charging board with DC jack, mini USB, micro USB, and USB Type-C port Battery test board for 18650, 26650, 14505 […]

Open-source LXI Tools is made for “LAN eXtensions for Instrumentation” compliant test instruments

LXI GUI screenshot

LXI Tools is an open-source project designed to manage Ethernet-connected test instruments such as oscilloscopes, power supplies, spectrum analyzers, etc… that are compliant with the “LAN eXtensions for Instrumentation” standard, or LXI for shorts, hence the name of the project. LXI Tools is available either as a command-line program (lxi) or a graphical user interface (lxi-gui), and includes features such as the automatic discovery of test instruments, sending SCPI (Standard Commands for Programmable Instruments) commands, grabbing screenshots from supported instruments, benchmarking SCPI message performance, and Lua scripting for test automation. The tool is compatible with higher-end instruments compatible with LXI from vendors such as Keysight Technologies, Kikusui Electronics, Rigol Technologies, Rohde & Schwarz, Siglent Technologies, and Tektronix. All support SCPI commands, while autodiscovery and screenshot functions are supported by most tested models. While it’s possible to build the project from source using meson, the easiest way to install LXI Tools […]

RIDEN RD6012P USB and WiFi DC power supply connects to your PC or smartphone

DC Power Supply USB WiFi

Renesas introduces sub 50 cents FPGA family with free Yosys-based development tools

Renesas FPGA family

Renesas has just unveiled the ForgeFPGA family of low-cost low-power FPGA’s to go for under 50 cents in (large) volumes following their acquisition of Dialog Semiconductors last August, who previously designed the GreenPAK programmable mixed-signal matrix. The company says its FPGAs consume half the power of competing FPGAs with a standby current of under 20uA, the price point will enable the use of FPGA in new markets and IoT products, and the tools will be free, at least as in beer, without any license to acquire or install. The full specifications are not available yet, but the ForgeFPGA Family will come with a maximum of 5,000 gates of logic, and the first devices ship with 1K and 2K Look Up Tables (LUTs), and as just mentioned, will operate at ultra-low power as low as 20 microamps in standby. ForgeFPGA is expected to target the same market as GreenPAK notably embedded […]

Cortex-M55 based Arm Virtual Hardware is now available in AWS Cloud

Arm Virtual Hardware Components

The Arm DevSummit 2021 is taking place on October 19-21, and the first announcements from Arm are related to IoT with “Arm Total Solutions for IoT delivering a full-stack solution to significantly accelerate IoT product development and improve product ROI”, “Project Centauri” aiming to achieve for an extensive Arm Cortex-M software ecosystem in the way that Project Cassini does for the Cortex-A ecosystem, starting with support for PSA Certified and Open-CMSIS-CDI cloud-to-device specification, and Arm Virtual Hardware based on Corstone-300 IoT platform with a Cortex-M55 MCU core and an Ethos-U55 microNPU accessible from Amazon Web Services. The first two are quite abstract right now, and more information may become available in the future, but the Arm Virtual Hardware is available now from AWS as a public beta, with 100 hours of free AWS EC2 CPU credits for the first 1,000 qualified users. The virtual hardware does not emulate only the […]

DT71 smart tweezers review – 3-in-1 tweezers, multimeter, and signal generator

DT71 Tweezers Signal Generator

Earlier this year, I discovered a new (to me) category of devices that look useful for electronics projects with smart tweezers Colibri ST-5S that integrate an LCR meter and can help quickly identify SMD components. I also noted some cheaper, but bulky models selling on Aliexpress for $15 and up. I’ve now received another compact model, yet affordable, as Seeed Studio sent me Miniware DT71 smart tweezers for review.  As we’ll see in this getting started guide, DT71 can be used both as a multimeter and a signal generator and sells for around $59 plus shipping. Miniware DT71 Smart Tweezers Unboxing Let’s first see what I received. the tweezers are stored in a plastic box that contains three parts. First, the arms fitted with replaceable tips clearly marked as positive (red) and negative (blue). There’s a 3.5mm audio jack that allows us to connect the microcontroller unit with a display, […]

Embedded Linux Conference (ELC) Europe 2019 Schedule – October 28-30

Embedded Linux Conference Europe 2019 Schedule

I may have just written about Linaro Connect San Diego 2019 schedule, but there’s another interesting event that will also take place this fall: the Embedded Linux Conference Europe on  October 28 -30, 2019 in Lyon, France. The full schedule was also published by the Linux Foundation a few days ago, so I’ll create a virtual schedule to see what interesting topics will be addressed during the 3-day event. Monday, October 28 11:30 – 12:05 – Debian and Yocto Project-Based Long-Term Maintenance Approaches for Embedded Products by Kazuhiro Hayashi, Toshiba & Jan Kiszka, Siemens AG In industrial products, 10+ years maintenance is required, including security fixes, reproducible builds, and continuous system updates. Selecting appropriate base systems and tools is necessary for efficient product development. Debian has been applied to industrial products because of its stability, long-term supports, and powerful tools for packages development. The CIP Project, which provides scalable and […]

STMicro Launches $10 STLINK-V3mini Mini Probe for STM32 MCUs

STLink-V3MINI

Last year, we reported STMicroelectronics launched STLink-V3 debugger & programmer for STM8 & STM32 microcontrollers that added I2C, SPI, and CAN interfaces compared the previous STLink-V2 model. It’s not particularly expensive either at $35, but if you ever wanted something more compact and cheaper, the company has now introduced STLink-V3mini debugger going for under $10. STLINK-V3Mini key features and specifications: JTAG / serial wire debugging (SWD) specific features: 3 V to 3.6 V application voltage support and 5 V tolerant inputs JTAG communication support SWD and serial wire viewer (SWV) communication support Virtual COM port (VCP) specific features: 3 V to 3.6 V application voltage support on the UART interface and 5 V tolerant inputs VCP frequency up to 15 MHz USB – Micro USB 2.0 connector for power and connection to host computer Misc – 2x color LEDs: communication, power; STDC14 signals protection Dimensions – 30 x 15 mm […]
