Researchers Developed a Very Powerful Mini Synchrotron That Can Fit On A Tabletop

A synchrotron is a particular type of cyclic particle accelerator which is used to accelerate quantum level charged particles at a very high velocity, traveling around a fixed closed-loop path.

It is one of the first accelerator concepts to enable the construction of large-scale facilities because they are very efficient in beam focusing, bending, and splitting the beam into different components. The most powerful modern particle accelerators such as Large Hadron Collider (LHC) in Switzerland uses bigger versions of the synchrotron design.

Scientists design mini synchrotron that is only 4m long

A synchrotron is mainly used for the production of X-ray in many medical, engineering or industrial fields. Researchers at Eindhoven University of Technology and Delft University of Technology will build and develop a new scaled down version of a synchrotron which will even fit on a tabletop. The intensity of the X-ray radiation of this device will be just as powerful as the larger ones. Smart*Light” is the name of this new synchrotron which they officially took under research on 23rd January.

With Smart*Light, the consortium wants to build a ‘scaled down synchrotron‘. A compact and tunable X-ray source which is less than 4 meters long, which can be used in any lab. The potential of application for such a device is huge in medical diagnostics, high-tech industries, aircraft, car, and ship manufacturing.

Using Smart*Light there is the opportunity to analyze the chemical composition of old or new artworks layer by layer. This does not only have importance for conservation but, also for research into authenticity too.

The operation of this revolutionary X-ray source is based on the physical concept where X-rays are produced from collisions between LASER light and accelerated electrons. The theory is known as Inverse Compton Scattering, and has already been recognized for decades, but only recently has the necessary technology been modern enough to be developed.

Espressif ESP32-PICO-KIT WiFi/WLAN+Bluetooth Module

ESP32-PICO-KIT V4 is a mini development board produced by Espressif. At the core of this board is the ESP32-PICO-D4, a System-in-Package (SIP) module with complete Wi-Fi and Bluetooth functionalities. Comparing to other ESP32 chips, the ESP32-PICO-D4 integrates several peripheral components in one single package, that otherwise would need to be installed separately. This includes a 40 MHz crystal oscillator, 4 MB flash, filter capacitors and RF matching links in. This greatly reduces quantity and costs of additional components, subsequent assembly and testing cost, as well as overall product complexity.

SensiBLEduino – A full fledge ‘hardware-ready’ development kit for IoT and supports Arduino

IoT which translates to the Internet of Things has been a significant buzz for the last five years while disrupting major Industries (from Agriculture, Energy, Healthy, Sports and several others).

SensiBLEduino
SensiBLEduino Development Kit

IoT adoption has seen rapid development in the makers’ world, with different makers and manufacturers producing various forms of boards, chips, software to facilitate quick IoT development. Boards like ESP8266 from Espressif System is used for rapid prototyping and a low-cost choice for Wi-Fi-based IoT applications. Israeli based IoT firm SensiEdge has launched the SensiBLEDuino, an off-the-shelf, hardware-ready development kit based on the open-source Arduino for rapid prototyping of IoT applications.

SensiBLE is a full fledge customizable solution for those wanting to design IoT products. It helps to fasten development with a variety of sensors onboard, along with Bluetooth LE 4.1 capabilities and a low-power ARM® 32-bit Cortex®-M4 CPU with FPU. Some of the main challenges when embarking on IoT product development are; what platform will I use? What sensors are available to achieve my goal(s)? How do I handle connectivity? What about the Cloud Platform to use, and so on. Developers or product designer always result in the use of several boards or modules to achieve this while also increasing the time to bring the product to life. The SensiBLE kit removes most of these fears; it combines hardware and software in tiny form factor to allow developers get their product to market quickly at lower development costs. (more…)

Odroid-N1 Features Gigabit Ethernet And Can Run Android 7.1, Ubuntu, Debian

The Rockchip RK3399 has revolutionized the open-spec single-board computer world. Hardkernel’s new Odroid project has made the multi-core SoC RK3399 to firm it’s grip further. Recently Hardkernel released images, specs, and extensive benchmarks on a prototype for its storage-oriented new Odroid-N1 board. The boards can be expected to launch for about $110 in May or June this year.

The 90x90x20mm SBC is highlighted for offering dual channel SATA III interfaces and 4GB DDR3-1866 dual-channel RAM. The Odroid-N1 can run Android 7.1, as well as Ubuntu 18.04 or Debian 9 with Linux Kernel 4.4 LTS. This new board can also be open source as its previous flagship Odroid-XU4.

The RK3399 features two Cortex-A72 cores that are clocked at up to 2.0GHz, as well as four Cortex-A53 cores, which are clocked at 1.5GHz. (Some other RK3399 boards have listed 1.42GHz.) This board also includes a high-end ARM Mali-T864 GPU. Hardkernel’s benchmarks have shown the hexa-core RK3399 based Odroid-N1 is running significantly faster on most tests, beating the Odroid-XU4’s octa-core (4x Cortex-A15, 4x -A7).

The Odroid-N1 is equipped with a GbE port, 2x USB 3.0 ports, and 2x USB 2.0 ports, HDMI 2.0 port for up to 4K Video output. There’s also a 40-pin GPIO header. The Power input is mentioned at 12V/2A, although attaching two 3.5inch HDD will require a 12V/4A PSU. As with the other RK3399 boards, there are no hopes of Raspberry Pi add-on compatibility.

The RK3399 has powered many similar SBCs previously. The first major RK3399 SBC was Firefly’s Firefly-RK3399, soon followed by Vamrs’ similarly open source Rockchip RK3399 Sapphire. More recently we’ve seen Shenzhen Xunlong’s Orange Pi RK3399.

The RK3399 is also finding key roles among many commercial boards. We just saw Aaeon take the leap with its OEM-oriented RICO-3399 PICO-ITX SBC. Earlier, Videostrong announced a VS-RD-RK3399 SBC.

ODROID-N1 key features:

  • Rockchip AArch64 RK3399 Hexa-core processor
  • Dual-core ARM Cortex-A72 2Ghz processor and Quad-core ARM Cortex-A53 1.5Ghz processor, big-LITTLE architecture
  • Mali-T860MP4 GPU, support OpenGL ES1.1/2.0/3.0, OpenCL 1.2
  • 4Gbyte DDR3-1866 RAM, Dual channel interface for 64bit data bus width
  • 2 x SATA3 port, native SATA implementation via PCIe-gen2 to SATA3 interface
  • eMMC 5.0 (HS400) Flash storage and a UHS capable micro-SD slot.
  • 2 x USB 3.0 host port
  • 2 x USB 2.0 host port.
  • Gigabit Ethernet port
  • HDMI 2.0 for 4K display
  • 40-Pin GPIO port
  • OS: Ubuntu 18.04 or Debian Stretch with Kernel 4.4 LTS, Android 7.1
  • Size: 90 x 90 x 20 mm approx. (excluding cooler)
  • Power: 12V/2A input (Attaching two 3.5inch HDD requires a 12V/4A PSU)
  • Price: US$110 (To be adjusted based on DRAM market price changes)
  • Mass production schedule: TBD

Simple Arduino Data Logger

Schematics

A data logger is an electronic device or instrument that records data over a period of time. It allows the user to record time or location stamped data which can be viewed at a later time or real time.

Irrespective of the type of data being logged or the kind of data logger, these devices usually contain two main units, the sensor unit and the storage/communication unit. The sensor unit may involve the use of an external instrument or a sensor embedded within the device. Increasingly, but not entirely, data logging devices are becoming more based on micro processors and microcontrollers, which has opened up a whole new level of data gathering and storage.
