The CAN bus is a serial communication protocol used in automotive and automation applications. The guys at ucandevices.pl have designed a solution around Orange Pi Zero board that allows you to log CAN bus data or act as a bridge between the CAN bus and Ethernet or WiFi. They call it “CAN Ethernet converter, CAN Logger, Linux CAN computer”. Sorry, no shorter name that I could find… uCAN (pronounced micro CAN) CAN Bus board specifications: Main Board – Orange Pi Zero with Allwinner H2+ quad core cortex-A7 processor, 256 MB RAM Network Connectivity – 10/100M Ethernet, 802.11 b/g/n WiFi Can Bus – 2-pin terminal block; support for CAN version 2.0 support Power Supply – DC 5V/2A via micro USB port Dimension – 50 x 50 x 20 mm The device comes pre-load with Debian distribution provided by Armbian plus various CAN tools. The getting started video below shows uCANTools web interface programmed with Node.js and running by default on the…

Cellular GPS trackers have been around for a few years, but so far mostly 2G or 3G GPS trackers with products like Ping, Particle Asset tracker, and many other models selling on Aliexpress. 4G GPS tracker have been less common. However, recently we’ve seen platforms like Wio LTE and AutoPi that could handle GPS tracking over LTE connectivity, and another alternative would be Mictrack MT600 that ready-to-use solution to track your car or other vehicle with GPS and 4G. Mictrack MT600 hardware specifications: GNSS U-BLOX7 GPS Chip GPS sensitivity -162dBm Channel – 56 Positioning Accuracy – 10m Cold start: 30s; warm start: 15s; hot start: 1s SMA antenna connector Cellular Connectivity Qualcomm 4G LTE chip MT600-A model (North America): 4G FDD LTE: 700/850/1700/1900MHz 3G UMTS: 850/1700/1900MHz GSM: 850/1900MHz MT600-C model (Asia): 4G FDD LTE: 900/1800/2100MHz 4G TDD LTE: 1900/2300/2500/2600MHz 3G UMTS: 900/2100MHz GSM: 900/1800MHz MT600-E (Australia/Asia/Europe) 4G FDD LTE: 800/850/900/1800/2100/2600MHz 3G UMTS: 850/900/2100MHz GSM: 850/900/1800/1900MHz MT600-J (Japan Only) – 4G FDD…

LimeSDR open source hardware software defined radio was launched last year with the promise of integration with Ubuntu Snap Store allowing to easily download and install various radio implementations such as LTE, WiFi, Bluetooth, LoRa, etc… It was offered for $200 and up as part of a crowdfunding campaign, but Lime Microsystems is back on CrowdSupply with a cheaper and low end version aptly called LimeSDR Mini.LimeSDR mini specifications: FPGA – Intel Altera Max 10 (10M16SAU169C8G) with 16K Logic gates, 549 KB M9K memory, 2,368 KB user flash memory Storage – 4 MB flash memory for data; 2x128KB EEPROM for RF transceiver MCU firmware and data RF Lime Microsystems LMS7002M RF transceiver Tx & Rx SMA connectors Frequency range – 10 MHz to 3.5 GHz RF bandwidth – 30.72 Mhz Sample Rate – 30.72 MSps with 12-bit sample depth Power Output (CW): up to 10 dBm USB – 1x USB 3.0 port via FTDI FT601 controller chip Expansion – 8-pin…

We’ve just published an article about a 3D printed jig to program some ESP8266 light bulbs, but as I watched Andreas Spiess’s latest video about ESP32 boards, he showed a board specifically designed to flash firmware to ESP-WROOM-32 or/and ESP-32S modules, which could be useful if you have many to program. The acrylic base does not appear to be offered by all vendors, as some use some standoffs instead to lift the board up. You just need to insert your compatible ESP32 module in the board, flash the firmware it, take it out, and more to the next module. It can also be used as a development board since it exposes I/Os via three 14-pin headers, comes with a on/off button, reset and program buttons, as well as a micro USB port for power, programming and debugging I first found it on Banggood, where it is sold for $14.99 shipped, the best price at the time of writing, but you…

Karl here. I have to say that my favorite part of 3D printing is designing things from scratch. Recently a reader was asking about a way to flash a lot of Ai Lights on a project he was working on. I suggested 3D printing a jig that pressure fits pins. He didn’t have a printer, and we exchanged contact information and he sent me one of the lights and some pogo pins from Amazon. Design in Fusion 360 I started by taking a picture of the light to get my pin placement. I set a scale by measuring a known distance then printed and tested. It took about 3 iterations to get them to line up in real life. Keep in mind camera lenses distort reality and knew It would take a couple times. I would just let a few layers print then stop and line everything up. I had a mostly working prototype in a couple hours. I did…

MeLE PCG35 Apo is a mini PC powered by Intel Pentium J3455, one of the most powerful Intel processors from Apollo Lake family, coupled with 4GB LPDDR3, 32GB eMMC flash and support for M.2 SSD and 2.5″ SATA HDD/SSD. The company sent me a sample for review, and I’ll start by taking photos of the device, accessories, and internal design, as well as showing how to install an M.2SSD and 2.5″ SATA drive, before publishing the second part of the review with Windows 10 at the end of next month. MeLE PCG35 Apo Unboxing The mini PC comes with the usual black package with gold fonts the company has used us to. The side shows the main specifications of the fanless mini PC.
