Raiscube Prusa I3 3D Printer Review – Part 1: Assembly, First Prints, and Configuration

Karl here. Today we are going to start looking a Raiscube Prusa I3 3D printer kit sent for review by GearBest. It’s very similar to most low cost 3D printer kits with one exception. The parts cooler is not like any similar kits that I have seen. In my short time researching these kits the parts cooler is one of the first upgrades I see people do. Typically the parts coolers are inadequate or nonexistent. We will find out that it is actually too good. In this review we are first going to outline the basic components and a mini build guide. Then we will look and see how it prints. Prusa I3 Desktop LCD 3D Printer Specs Main Features: Mainboard: Melzi V2.0 210 x 210 x 210mm build volume 12864 LCD screen shows your printing information directly and easy for you to manipulate 8mm-thick laser cut acrylic frame for […]

Flexible & Adhesive LEGO TAPE Could Be Useful for Makers / DIY Projects

I remember when the Raspberry Pi board first launched, there was no case, and LEGO case designs were popular, and there are certainly various ways you could use LEGO in your projects. But I’ve just discovered LEGO tape that could bring much more flexibility to your design. It’s just like LEGO, but flexible, and with an adhesive flat side, so you can cut it to any size you want, and stick it anywhere. “Back to Realitee” shop sells those for $12.95 for 1 meter tapes. available in various colors. This allows kids to play differently with LEGO by sticking to wall, or making special shapes. If times are stuff, and you’d like to spend less, Aliexpress has similar LEGO tapes, with the cheaper ones without a sticky side, so you’d have to use you own double sided sticky tape. Prices start at $0.89 shipped for 25cm, and $3.79 for 1 […]

Getting Started with OpenCV for Tegra on NVIDIA Tegra K1, CPU vs GPU Computer Vision Comparison

This is a guest post by Leonardo Graboski Veiga, Field Application Engineer, Toradex Brasil Introduction Computer vision (CV) is everywhere – from cars to surveillance and production lines, the need for efficient, low power consumption yet powerful embedded systems is nowadays one of the bleeding edge scenarios of technology development. Since this is a very computationally intensive task, running computer vision algorithms in an embedded system CPU might not be enough for some applications. Developers and scientists have noticed that the use of dedicated hardware, such as co-processors and GPUs – the latter traditionally employed for graphics rendering – can greatly improve CV algorithms performance. In the embedded scenario, things usually are not as simple as they look. Embedded GPUs tend to be different from desktop GPUs, thus requiring many workarounds to get extra performance from them. A good example of a drawback from embedded GPUs is that they are […]

8Power Vibration Energy Harvesting Technology Powers Batteryless LPWAN GPS Trackers, MEMS Sensors

While IoT products usually promises one to 10 years battery life, they will be several billions of them, and ARM’s CEO even forecast one trillion IoT devices in the next 20 years. Recharging batteries at home may be fine, but imagine having to recharge or replace batteries on top of electric poles, inside walls, in remote locations, and other hard to reach places, considerable resources would have to be deployed just to replace or recharge battery every year or whenever the battery is close to being depleted.  That’s why work on energy harvesting technology for batteryless devices may be so important, and 8Power is one of the companies working in the field through their vibration energy harvesting technology that is said to harvest up to 10x the power of competing devices under comparable condition thanks to the use of parametric resonance phenomenon. The company has recently announced their Track 100 family […]

Arduino Cinque Combines SiFive RISC-V Freedom E310 MCU with ESP32 WiFi & Bluetooth SoC

SiFive introduced the first Arduino compatible board based on RISC-V processor late last year with HiFive1 development board powered by Freedom E310 MCU, but  the company has been working with Arduino directly on Arduino Cinque board equipped with SiFive Freedom E310 processor, ESP32 for WiFi and Bluetooth, and an STM32 ARM MCU to handle programming. Few other technical details have been provided for the new board, but since it looks so similar to HiFive1, I’ve come with up with preliminary/tentative Arduino Cinque specifications: MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) WiSoC – Espressif ESP32 for WiFi and Bluetooth 4.2 LE Storage – 32-Mbit SPI flash I/Os 19x Digital I/O Pins 19x external interrupt pins 1x external wakeup pin 9x PWM pins 1/3 SPI Controllers/HW CS Pins I/O Voltages –  3.3V or 5V supported USB – 1x micro USB port for power, […]

Top Programming Languages & Operating Systems for the Internet of Things

The Eclipse foundation has recently done its IoT Developer Survey answered by 713 developers, where they asked  IoT programming languages, cloud platforms, IoT operating systems, messaging protocols (MQTT, HTTP), IoT hardware architectures and more.  The results have now been published. So let’s have a look at some of the slides, especially with regards to programming languages and operating systems bearing in mind that IoT is a general terms that may apply to sensors, gateways and the cloud, so the survey correctly separated languages for different segments of the IoT ecosystem. C and C++ are still the preferred languages for constrained devices, and developers are normally using more than one language as the total is well over 100%. IoT gateways are more powerful and resourceful (memory/storage) hardware, so it’s no surprise higher level languages like Java and Python join C and C++, with Java being the most used language with 40.8% […]

Sen5 Amlogic S905D TV Box Review – Part 2: Android Firmware, Kodi 17, and DVB-T2 & S2 App

Sen5 is one of the first Android TV boxes powered by Amlogic S905D processor, and comes with two tuners (DVB-C/T/T2 and DVB-T/T2) with two demodulators that should allow for recording on one tuner, while watching the other, or recording two channels at the same time. We’ve already check out the hardware in the first part of the review, and seen a glimpse of the neat user interface, so today I’ll report about my experience with the device. Sen5 Android Set-Top Box First Boot, Setup Wizard, & First Impressions The STB comes with two USB ports so I used one for the hard drive, a necessity if you plan to use the PVR function, and connected a USB hub to the other with RF dongles for an air mouse and a gamepad, as well as a USB keyboard to take screenshots. I also connected Ethernet and HDMI cables, as well as […]
