Split Home Energy Meter Combines ESP32 with Microchip ATM90E32 IC (Crowdfunding)

It’s always useful to monitor the electricity consumption of your house, as you can easily and quickly find out whether an appliance is suddenly consuming a large amount of electricity before finding out from your next utility bill. It can also help remotely monitoring if an appliance has stopped working and fix it as soon as possible, for example an electric pipe heater making sure your pipe do not freeze in a holiday home. In many cases, a qualified electrician needs to be involved for the installation of whole home energy meters both for safety and insurance matters. We’ve seen in the past energy meters fit easily into a circuit breaker box but they may not be suitable for all setups. I’ve previously reviewed an inexpensive digital clamp meter that you just need to clip on one of the wire connected to your home without having to mess with dangerous […]

Google Pixel 3a / 3a XL Mid-Range Smartphones Get a Premium Camera, an Headphone Jack

Google launched their Pixel 3 & 3 XL smartphones last fall with a Snapdragon 845 processor, a camera that takes excellent photos even in low-light conditions, and achieves an excellent score of 101 points in Dxo camera benchmark. The phone costs $799 and up in the US, and more in other countries. Most people I know use their phone for calls and SMS, taking photos, messaging with Facebook and LINE, and some casual gaming, so it would make sense to have a mid-range phone with an excellent camera, a slightly less powerful processor, and a significantly lower price tag. That’s what Google has done with Pixel 3a and 3a XL phones, taking many of the features of Pixel 3, including the camera, but selecting a Snapdragon 670 processor instead, shaving a few dollars with other design decision, and bringing the price down to $399. Pixel 3a / 3a XL smartphone […]

Grove AI HAT Helps Raspberry Pi Run Edge Computing Workloads

Last year we wrote about Kendryte K210 dual core RISC-V processor specifically designed for for machine vision and machine hearing as well as the corresponding Kendryte KD233 which enables inference at the edge, e.g. tasks such as face recognition or object detection. Latter on we found the processor in Sipeed M1 module which went for as low as $5 in a crowdfunding campaign, and was fitted to some low cost boards now selling for $12.90 on Seeed Studio. The latter company has now designed Grove AI HAT that aims to assist Raspberry Pi in running the edge computing workloads previously described, as exposes 6 Grove interfaces to extend functionality with some of the Grove add-on modules. Grove AI HAT specifications: AI Module – Sipeed “MAIX” M1 with Kendryte K210 dual core RISC-V processor @ 600 MHz, KPU Convolutional Neural Network (CNN) hardware accelerator, APU audio hardware accelerator, 8 MB general […]

Pinebook Pro Arm Laptop Video Demo

Pine64 first revealed working on Pinebook Pro Arm Linux laptop at FOSDEM 2019 back at the end of January. The first Pinebook laptop had limited hardware resources, and as such was meant for simple tasks, but Pinebook Pro equipped with Rockchip RK3399 processor, 4GB RAM, 64GB to 128GB flash, and a 14″ Full HD display is designed to be used as your main laptop. That means everything needs to work from 3D graphics acceleration, to hardware video decoding, and USB-C video output. Lukasz Erecinski very recently shot a demo of the laptop in action, and everything looks very good, meaning the laptop should be come available soon. You can watch the demo further below, but if you are in a rush here’s what has been tested and works: Ubuntu & Debian with MATE desktop 4K video playback 3D graphics acceleration for games (Quake demo) 3D graphics acceleration in Chromium web […]

Toradex Torizon Industrial Linux Distribution Targets Windows Developers

When we interviewed Toradex right before Embedded World 2019, they told us they would focus on their new software offering called Torizon, an easy-to-use industrial Linux Platform, especially targeting customers are coming from the Windows / WinCE environment or who have only experience with application development and are not embedded Linux specialists. The company has now officially launched Torizon, and provided more details about their industrial open source software solution especially optimized for their NXP i.MX modules. Torizon specifically relies on foundries.io Linux microPlatform which provides full system with a recent stable kernel, a minimal base system built with OpenEmbedded/Yocto, and a runtime to deploy applications and services in Docker containers. The microPlatform is part of TorizonCore (light blue section above) that also includes an OTA client (Aktualizr). TorizonCore is free open-source software, and serves as the base to run software containers. To get started, Torizon provides a Debian container […]

This Open Source Hardware Smartwatch Project is Fully Documented

While there are plenty of smartwatches available, they may not perfectly match your requirements and needs. But did you wake up one day and just decided to build your own? Probably not. But Samson March had his own plans, and as a professional electrical engineer and product designer, he decided to start a smartwatch project during his spare time. What makes it really interesting is that he provided a long list of photos and short videos explaining in details the process, and open-sourced all materials from hardware design files, to firmware source code, and 3D print files for the body and charging dock! The OSHW watch does not have a name (yet) and features the following hardware: Wireless MCU – Dialog Semiconductor DA14683 Arm Cortex-M0 microcontroller up to 96 MHz 128KB RAM, 128KB ROM, 64KB OTP, and with Bluetooth 5.0 connectivity Storage – 128 Mbit SPI flash Display – 1.3″ […]
