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

Split Home Energy Meter

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 Pixel 3a

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 […]

MORPHEUS Claims to be an Unhackable RISC-V Processor Architecture

MORPHEUS Unhackable RISC-V Processor

Code gets continuously written and updated for new features, optimizations and so on. Those extra lines of code sometimes come at a cost: a security bug gets inadvertently introduced into the code base. The bug eventually gets discovered, a report is filled, and a software fix is committed to solve the issue, before the new software or firmware to push to the end user. This cycle repeats ever and ever, and this means virtually no software or device can be considered totally secure. The University of Michigan has developed a new processor architecture called MORPHEUS, and that blocks potential attacks by encrypting and randomly reshuffling key bits of its own code and data several times per second through a “Churn Unit”. The new RISC-V based processor architecture does not aim to solve all security issues, but focuses specifically on control-flow attacks made possible for example by buffer overflows: Attacks often […]

miriac MPX-LS1028A NXP QorIQ LS1028A SoM Targets TSN Applications with HMI Display

LS1028A System-on-Module

NXP QorIQ LayerScape LS1028A communication SoC was first unveiled in March 2017 with two Armv8 cores, GPU and LCD controller for HMI systems, as well as Time-Sensitive Networking (TSN) capabilities useful in industrial settings. As usual it takes a while before the company finalize their design and software support, but LS1028A has started to appear at least in one hardware platform that’s supposed to launch this quarter (Q2 2019): MicroSys miriac MPX-LS1028A system-on-module. miriac MPX-LS1028A SoM specifications: SoC – NXP QorIQ LS1018 / LS1028 single / dual core Arm Cortex-A72 clocked at up to 1.3 GHz with MXC Vivante GPU, Mali Display Processor, configurable cryptographic offload engines (Optional: LS1017/LS1027 without GPU for cost saving) System Memory – Up to 4GB 32 Bit DDR4 with ECC RAM at up to 1600 MT/s Storage – Up to 256MB Serial NOR Flash & up to 4GB Serial NAND Flash; EEPROM MXM 2.0 edge […]

Aconno Bluetooth Beacons Come with Various Sensors, Nordic Semi nRF52 BLE SoC

Aconno Bluetooth Beacons

We first covered products from Aconno is 2017 with their Bluetooth LE development board powered by the company’s ACN52832 BLE module based on Nordic Semi nRF52832 ARM Cortex-M4 multi-procotol wireless SoC. Since then they’ve launched several small Bluetooth beacon modules based on ACN52832, and the company has what they call a presale promotion until May 21st, but it looks really like a group buying event for their existing BLE modules where the price goes down as more people purchase modules. Six Bluetooth modules are offered: acnSENSA multisensor Bluetooth tag with temperature, light, humidity, barometer, accelerometer, magnetometer, gyroscope acnBEACON programmable Bluetooth tag acnACT BLE beacon with button and RGD LED, magnetometer, phototransistor acnNFC programmable Bluetooth tag with NFC tag emulator acnRANGE distance measuring beacon with time-of-flight sensor acnFIND Bluetooth smart tag with LED, sound and accelerometer All modules come with a replaceable CR2450 battery, and IP65 enclosure. Pricing currently ranges from […]

Linux 5.1 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.1 Changelog

Linus Torvalds has just announced the release of Linux 5.1: So it’s a bit later in the day than I usually do this, just because I was waffling about the release. Partly because I got some small pull requests today, but mostly just because I wasn’t looking forward to the timing of this upcoming 5.2 merge window. But the last-minute pull requests really weren’t big enough to justify delaying things over, and hopefully the merge window timing won’t be all that painful either. I just happen to have the college graduation of my oldest happen right smack dab in the middle of the upcoming merge window, so I might be effectively offline for a few days there. If worst comes to worst, I’ll extend it to make it all work, but I don’t think it will be needed. Anyway, on to 5.1 itself. The past week has been pretty calm, […]

Grove AI HAT Helps Raspberry Pi Run Edge Computing Workloads

Grove AI HAT

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 […]
