Toybrick TB-RK1808 AI Compute Stick is now Available for $86

Last May, we wrote about RK1808 AI Compute Stick, a USB stick with Rockchip RK1808 dual-core Cortex-A35 processor also featuring a 3.0 TOPS neural processing unit to accelerate AI workloads at low power. As I understood it, it was available for purchase, but you had to contact a Rockchip FAE by email in order to get one. Now, you can easily buy one online by getting the Toybrick TB-RK1808 AI Compute Stick on Seeed Studio for $86. Just ignore the “Core i3” in the title, we’ll see why it’s there further below. TB-RK1808 AI Compute Stick specifications: SoC – Rockchip RK1808 dual-core Cortex-A35 processor with NPU AI inference performance – 3 TOPS for INT8, 300 GOPS for INT16, 100 GOPS for FP16 System Memory – 1GB LPDDR Storage – 8GB eMMC flash Host Interface – USB 3.0 type-A port Power Supply – Via USB port Dimensions – 82 x 31 […]

MDP-XP is A Modular DC Power Supply Kit For Your Next Project

My love for modular power supply design can not be denied. I find it cool, how you can increase the functionality of relative less powerful device just by adding another device on top or connected to it. With the explosion of the Arduino shields, the Raspberry Pi HaTs, I must say hardware modular design will surely be here for a long time. An interesting modular product discovered on SeeedStudio is the MDP-XP Smart Digital Power Supply Kit. This product is a new product carried by Seeedstudio as it can be seen on the front page, and it is an interesting product indeed. The MDP-XP known as Mini Digital Power System is a system of programmable linear DC power supply inheriting the modular design concept where you can enhance the basic functionality of the device. It is a cost-effective DC power supply, featuring indicators, stability, reliability and distinct user interface comparable […]

MakerPower Solar Power Supply/Charger for IoT & Embedded Systems Supports Lead-acid Batteries (Crowdfunding)

Danjuliodesigns llc. A boutique embedded systems design firm run by engineer and inventor Dan Julio has set up crowdfunding for the makerPower Solar power supply/charger for intelligent power supply just about anywhere and in any climate. A comprehensive device structured to IoT and embedded systems, where sometimes a remote camera or other device needs power all the time. The power source is a solar panel which can charge a standard lead-acid battery (USA availability only) We reported on a solar input board PiJuice battery HAT and although there are other solar input devices on the market, such as the PiJuice, for use with SBC’s such as Raspberry Pi, the makerPower Solar functions at a higher level, incorporating intelligent power control and functioning. The board can be source powered by solar panel through a standard lead-acid battery, rather than a Li-Po or Li-Ion. The inventor felt a source should carry as […]

TensorFlow Lite for Microcontrollers Benchmarked on Linux SBCs

Dimitris Tassopoulos (Dimtass) decided to learn more about machine learning for embedded systems now that the technology is more mature, and wrote a series of five posts documenting his experience with low-end hardware such as STM32 Bluepill board, Arduino UNO, or ESP8266-12E module starting with simple NN examples, before moving to TensorFlow Lite for microcontrollers. Dimitris recently followed up his latest “stupid project” (that’s the name of his blog, not being demeaning here :)) by running and benchmarking TensorFlow Lite for microcontrollers on various Linux SBC. But why? you might ask. Dimitris tried to build tflite C++ API designed for Linux, but found it was hard to build, and no pre-built binary are available except for x86_64. He had no such issues with tflite-micro API, even though it’s really meant for baremetal MCU platforms. Let’s get straight to the results which also include a Ryzen platform, probably a laptop, for […]

HuskyLens AI Camera & Display Board is Powered by Kendryte RISC-V Processor (Crowdfunding)

A couple of years ago, I reviewed JeVois-A33 computer vision camera  powered by Allwinner A33 quad-core Cortex-A7 processor running Linux. The tiny camera would implement easy-to-use software for machine vision with features such as object detection, eye tracking, QR code and ArUco marker detection, and so on. The camera could handle the tasks at hand, but since it relied on purely software computer vision, there were lag for some of the demo applications including 500ms for single object detection, and up to 3 seconds for YOLO test with multiple object types using deep learning algorithms. That’s a bit slow for robotics project, and software solutions usually consume more than hardware accelerated ones. Since then, we’ve started to see low-cost SoC and hardware with dedicated hardware AI accelerators, and one of those is Kendryte K210 dual-core RISC-V processor with a built-in KPU Convolutional Neural Network (CNN) hardware accelerator and APU audio […]

Your Smartphone Totally Needs a $15 Cooling Fan

2019 is the year of (silly) cooling fans for SBCs and smartphones! After ICE Tower cooling fan for Raspberry Pi 4, and ROG AeroActive Cooler II for ASUS’ latest gaming smartphone, you’ll be pleased to know you can now add a USB powered cooling fan to most smartphones to keep up working optimally in all conditions. You can get this beauty for just $14.99 shipped on Banggood. The cooling fan just clips to your smartphone and is compatible with mobile phones with a 62 to 85mm width since it’s adjustable. It’s made of ABS plastic and measures 80 x 68 x 49 mm. The mobile phone cooler ships with a USB cable to power it. This will quickly deplete your battery though, so they recommend using a power bank instead. Most people will find a smartphone fan to be a ridiculous idea, but a few years ago, I had a […]

Khadas VIM3 (Amlogic A311D) Benchmarks & System Info in Android 9

I received Khadas VIM3 kit at the very beginning of this month, and showed the content of the kit, and how to assemble it. Now after clearing some other items for review, I’ve started to play with the Amlogic A311D board which ships with Android 9.0 by default.  I’ll focus my efforts on Ubuntu as most people will run Linux distributions on the board, but before doing so I’ve upgraded Android to the latest version, and checked out system information and ran some benchmarks in Android. Installing the latest Android firmware on VIM3 Instructions to upgrade the firmware over USB-C are available for Windows and Ubuntu, but since my laptop runs Ubuntu 18.04 I’ll focus on the latter. We can install the burn-tool for Linux as follows:

We can now download and extract the latest Android image:

Once it’s done you can connect your VIM3 board to your […]

Elk, An Allwinner H3 Development board Crafted For the Decentralized Internet (Crowdfunding)

Back in 2017, Bitcoin peaked at almost $20,000; many were pretty shocked about how this supposed virtual currency suddenly become a scare resource. It also brought limelight to the technology behind it Blockchain and the idea of Decentralized internet. Although the success of the cryptocurrency didn’t last that long, as it lost about 80 percent in a year and still categorized as one of the biggest bubbles in financial history. After the crash of Bitcoin and some other similar cryptocurrencies, a lot of people predicted that’s the end of the whole Blockchain thing, and the idea of Decentralized internet will not happen. The recently announced Facebook Libra, a new cryptocurrency by the American giant Facebook, shows that Blockchain and the Decentralized web isn’t going anywhere and will probably start growing stronger. Arduino made it possible for Artist, Makers, Engineers, Students to bring ideas to life and quickly make things easier. Now, […]
