MeanWell Mini Switching Power Supplies May Be Useful for Development Boards

While some people or organizations with lots of boards may use high-end USB hubs to power and control them, most people likely use wall adapters to power their development boards like Raspberry Pi 3, ASUS Tinkerboard, Orange Pi PC, and so on. At least that’s what I do, except in some cases when I suspect power issues, and I go with a more powerful SMPS (switch mode power supply). I don’t use it often because it’s a large brick and expose 220V. But the other day, as I attended Chiang Mai Maker Party, I found one maker uses some tiny (and cute) power supply from a company called Mean Well to power his Raspberry Pi boards. The model used above with RS-15-5 with takes 100-240VAC 0.35A input, and output 5VDC up to 3A. The power supply include AC Neutral, AC Live, Ground, DC V+ and DC V-  pins where you […]

Turn Your Raspberry Pi into a “Smartphone” or Cellular IoT Gateway with PiTalk 3G HAT (Crowdfunding)

The Raspberry Pi boards are used in a countless number of projects, and some of those turn one of Raspberry Pi boards into a (thick) smartphone powered by Linux. The first one was probably PiPhone based on Raspberry Pi 1 Model B, and other followed suit such as TyTelli based on Raspberry Pi Model A+, and more recently ZeroPhone powered, as its name implies, by Raspberry Pi Zero board. UK based SB Components Ltd is offering another option with their PiTalk HAT based on a Quectel 3G UMTS module, and kits adding a 3.2″ to 5″ display, an optional camera, and/or Raspberry Pi 3 board. PiTalk board specifications: Cellular Connectivity Quectel UC15 3G/2G UMTS/HSDPA and GSM/GPRS/EDGE module with up to 3.6 Mbps download, 384 Kbps upload SMA antenna connector Push push SIM card holder Voice, SMS and data support Audio – 3.5 mm audio jack, speaker and mic support via […]

Anavi Light pHAT Adds RGB Light Strip Support to Raspberry Pi Boards (Crowdfunding)

He works as a software engineer for his main job, but Leon ANAVI is apparently enjoying his hobby of designing open source hardware, as after RabbitMax Flex home automation HAT, and ANAVI Infrared pHAT with IR transmitter and receiver, he has come up with as third project: Anavi Light pHat, an add-on board for Raspberry Pi 3/Zero (W) that adds support for RGB light strips. Light pHAT specifications: Compatible with 40-pin Raspberry Pi header EEPROM with board manufacturer information and a device tree fragment Terminal block for a 12V RGB LED strip 3x 4-pin I2C headers for sensor modules 1x 3-pin header for PIR motion sensor 1x 4-pin UART header for debugging Dimensions – pHAT form factor You first need to connect the pHAT to your board, and then LED strip, and you can then control the lights using Home Assistant open source home automation platform, with the strip integrated […]

Gumstix AutoBSP Automatically Generates Device Tree Files for Hardware Designed with Geppetto

Gumstix launched Geppetto Design-To-Order (D2O) system back in 2013, and at the time you could design complete baseboard for their Overo CoMs right in your Chrome or Firefox web browser, and once complete, order the board from the website. The system is meant to save you time, and “design” here does not mean drawing schematics, and laying out PCBs, but instead selecting board size, and adding ports as needed. Since then, the company has added support for more modules, and you can now easily build you own baseboard for Raspberry Pi Compute Module, Technexion PICO-IMX6 module, Toradex Colibri SoM, 96Boards Mezzanine, and they even have Beaglebone Black and 96Board CE or IoT connectors, among others. Support for Qualcomm DragonBoard 410c, Atmel (Arduino) , and STMicro platforms is also being worked on. Their latest feature – AutoBSP – automatically generates device tree files for your custom boards, so you can simply […]

A Day at Chiang Mai Maker Party 4.0

The Chiang Mai Maker Party 4.0 is now taking place until December 9, and I went there today, as I was especially interested in the scheduled NB-IoT talk and workshop to find out what was the status about LPWA in Thailand. But there are many other activities planned, and if you happen to be in Chiang Main in the next few days, you may want to check out the schedule on the event page or Facebook. I’m going to go though what I’ve done today to give you a better idea about the event, or even the maker movement in Thailand. Booth and activity area should be the same over the 4 days, but the talks, open activity, and workshop will be different each day. Today, people could learn how to solder in the activity area. The even was not really big with manufacturers/sellers like ThaiEasyElec, INEX, or Gravitech closer […]

$45 AIY Vision Kit Adds Accelerated Computer Vision to Raspberry Pi Zero W Board

AIY Projects is an initiative launched by Google that aims to bring do-it yourself artificial intelligence to the maker community by providing affordable development kits to get started with the technology. The first project was AIY Projects Voice Kit, that basically transformed Raspberry Pi 3 board into a Google Home device by adding the necessary hardware to support Google Assistant SDK, and an enclosure. The company has now launched another maker kit with AIY Project Vision Kit that adds a HAT board powered by Intel/Movidius Myriad 2 VPU to Raspberry Pi Zero W, in order to accelerate image & objects recognition using TensorFlow’s machine learning models. The kit includes the following items: Vision Bonnet accessory board powered by Myriad 2 VPU (MA2450) 2x 11mm plastic standoffs 24mm RGB arcade button and nut 1x Privacy LED 1x LED bezel 1x 1/4/20 flanged nut Lens, lens washer, and lens magnet 50 mil […]

ZeroShell Firewall/Router Linux Distribution Works on x86 Hardware, Raspberry Pi 2/3, & (Some) Orange Pi Boards

We’ve just seen pfSense is now available for Arm via firewall appliances such as Netgate SG-3100, but AFAIK there’s no pfSense community Arm firmware images yet. Several Arm SoCs & boards are now supported by FreeBSD, so in theory pfSense could be ported to those, but the page on FreeBSD does not seem to have been updated for a while. If you want a firewall distributions with an easy-to-user web interface like pfSense, but that also works on cheaper Arm hardware, Linux based ZeroShell distribution could be worth a try, as beside working on Intel & AMD x86 platforms, the developers also provides images for Raspberry Pi 2 & 3 boards, and several Orange Pi boards, namely Orange Pi R1, Orange Pi Zero, Orange Pi PC, and Orange Pi Plus/Plus2. The latter is the only supported Arm board with Gigabit Ethernet. Some of ZeroShell features include: Load Balancing and Failover of […]

Acme CM3-Home is a Raspberry Pi 3 Compatible Board Designed for Home Automation

Raspberry Pi CM3 & CM3L modules are used in so many devices it’s hard to keep up. From NEC digital signage displays, to industrial touch panels, and IoT gateways, the Broadcom BCM2837 based system-on-module are found in more and more products and solutions, and number of announcements seems to have increased over the last few months. The latest product to leverage Raspberry Pi CM3L SoM is made by Italy based Acme Systems, and designed for home automation. CM3-HOME comes with opt0-isolated inputs compatible with KNX and DALI buses, various connectivity options (Ethernet, WiFi, Bluetooth, 868MHz ISM radio…), and other expansion port. Two edition of the boards are available: LITE and FULL, with the former suitable for most home automation project, and the latter adding support for some commercial lighting systems and energy harvesting Radio ISM nodes.
