MS6812 Cable Finder Helps You Locate Wires With Ease

Having to trace tangled and enclosed wires can be tiring and annoying. However, the Mastech MS6812 cable tester helps you solve the problem. The tester is designed to locate a single wire or cable and trace its path in the cable line without damaging the insulation. The locator is made out of durable high-quality plastic in green color. Its antenna is located at the top end of the receiver, and the volume control is located on the side. The locator comprises of a transmitter and a signal receiver, which can track the route of the cable laying, search for a wire, test for wire breakage, detect the location of the wire break, determine the polarity, integrity, and state of telephone lines when connecting the transmitter to telephone sockets and send a single tone signal over the wires. The MS6812 enables you easily find hidden wiring for electrical and telephone cables, find a broken cable break, wire continuity (ring the cable), detect a tone and determine the polarity in a telephone line, and determine line status.

The Mastech MS6812 is a good tool for technicians who lay, maintain, and repair telephone lines. The main components in the cable tester consist of a receiver and a transmitter. The transmitter works by generating a sinusoidal signal with a frequency of about 2 kHz. The transmitter is equipped with red and black connecting wires and a standard 4-wire telephone cable with a plug. The receiver is equipped with a highly sensitive sensor and amplifier. If you want to search for a wire, you turn on the transmitter, connect the black wire to the case or ground, and the red wire to the circuit you are searching through. The receiver must be brought to the line you are searching through, you will hear a higher sound volume when you are close to the desired conductor. The volume control in the receiver enables you to increase the sensitivity and tune the device to your desired operating conditions. You can also use headphones with the device, it is equipped with a special connector for this connection. To power the device, there is a 9V battery.

If you are working in a noisy room, you can connect a headphone to the device. You can connect the headphone at the bottom, where you will find a standard 3.5 headphone jack. The speaker and the on / off button of the device are located on the top panel of the Mastech MS6812 locator device. We should note that the blue button for turning the tester on and off has no latch, so Mastech works only if it is kept constant. The Mastech is powered by a battery, and you can find the battery compartment at the bottom. The transmitter features 2 LEDs that light up when the tester is running. This helps to relay information when checking the integrity and condition of telephone lines. Each tone indicates which mode is on.

The outputs of the Mastech transmitter must be connected to the line under investigation. The output is also an RJ-11 connector that can connect to telephone sockets. The transmitter also features another switch on the board, which is discrete volume control. The MS6812 enables you easily find hidden wiring for electrical and telephone cables, find a broken cable break, wire continuity (ring the cable), detect a tone and determine the polarity in a telephone line, and determine line status.

Meet the $199 cluster kit with support for four Jetson Nano or NX modules

The Jetson family of development kits and SOMs have proven to be pivotal in the realization of AI-based implementations across several applications from robotics to computer vision. They enable both hobbyists (via the kits) and professionals (via the SOMs) quickly prototype, develop, and deploy ML/AI algorithms and applications.

Alone, the boards are quite powerful, but one common desire users of the Jetson platforms have had for a while, especially for industrial edge applications, is to be able to combine multiple Jetson boards/SOMs to increase the processing capability available for their project. Several solutions like the PicoCluster series have been adopted but their inability to provide users with the production-ready look available with kits like the turning pi, was a disappointment to most users and reduced adoption.

All of these are however set to change, as Seeed Studio, the popular Shenzhen-based Electronics component manufacturer, last week, announced the launch of the Jetson Mate; a carrier board kit that allows users to create a cluster with up to 4(four) Jetson Nano or Jetson Xavier NX modules, leveraging on the pin compatibility nature of both modules.

Unlike the previous attempts at the problem, the Jetson mate comes in a high-quality, production-ready, fancy enclosure.  The mate features SODIMM slots for 4 SOMs one of which is designated to serve as the slot for a master module while the other modules are designated as workers. As you will expect, certain features like software upload, are peculiar to the master slot, but performance across the board in terms of processing is fairly the same, with the master only serving as an entry point to the cluster. Each of the worker SOMs can be powered on or off separately, filling the need for applications that need to switch between SOMs.

Communication between the SOMs and the outside world (internet or Local) is enabled by an onboard 5-port gigabit switch which enables the 4 SoMs to communicate with each other, with the last port of the switch used for uplink connection to a network via an onboard Gigabit Ethernet port.

In addition to the ethernet port, the Jetson mate features 1 USB 2.0 port which connects to the Master node, and 4 USB3.0 ports one of which is also connected to the master and the other 3 to each of the worker nodes. The mate also features 2 CSI ports for possible camera connections, a UART debug port, a USB-C port which can be used for OS Upload among others, and a 4-pin port to which the giant 12v fan at the top of the kit is connected.

The Jetson Mate has been receiving a huge amount of praise from the ML/AI/Edge computing community since its announcement and while it’s still in production and not yet fully available, the pre-order page on Seeed’s website, where the board is currently being sold for $199, has no doubt been busy.

More information on the Jetson mate, its application, price, and user guide is available on the product’s page on Seeed’s website here.

600W Step-Up Boost Converter (12 – 60 V / 10 A) with Adjustable Voltage and Current

As a maker, we are always looking for the best way to power our projects. Usually, buck and boost converters are a considerable part of our project, because without good power, then everything else can be compromised. As important as it is, one does not want to splurge huge amounts of money on something that barely contributes to the end experience, but we also want the power supply to be reliable and sleep without wondering if everything can burn down easily, i.e. is protected. But enough mumbling about safety. Today, we bring you a cool boost converter that you may want to include into your next projects.

Over on Tindie, there is this interesting step up converter that can handle up to 600W of power. The interesting power rating is backed by adjustable voltage from 12 to 60 V and current from 0.2 to 10 A, starting with a 10 to 60 V input. Besides that, the input is protected through a fuse, so if you mess up too badly, there is the savior, ready to sacrifice itself for your circuitry. Looking at the outside, the connections are bare wires, which is justifiable due to the high currents, since not all connectors would handle that much current (and you probably do not intend to keep changing the connected cables), and the adjustments of both voltage and current are made through a trimmer potentiometer, that can surely handle with precision the large scales.

Regarding specifications, what is there for us to consider? Let us take a look:

  • Input voltage from 10 to 60 V DC
  • Continuously adjustable output voltage from 12 to 60 V
  • Constant adjustable current range from 0.2 to 10 A
  • Output current of up to 10 A (but needs a beefier heatsink for more than 6 A of current)
  • Static operating current of 10 mA
  • Maximum input current of 10 A, protected by a fuse
  • Operating switching frequency of 150 kHz (no audible hissing)
  • Conversion efficiency ranging from 92 to 96 %
  • Operating temperature range from -40 to +85 ºC
  • Dimensions of 85 x 52 x 21 mm and weight of 80 grams

Unfortunately, there is no reverse protection on the input, but aside from that, there is not much to complain, you get what is described, which is good enough. But what can you do with it? Well, if you need ideas, there is a lot to apply it on. Besides powering those projects that need a bit more current than the popular 3 A limit, you can DIY an old PC power supply to an adjustable 12 to 60 V laboratory PSU, which always comes in handy. Lastly, let us discuss the price: located at $23.80, we would say it is not ridiculously overpriced, just right.

Keybon: DIY a Functional (but Elegant) Macro Keyboard

So, we have all been there. Looking at our keyboard, adding bindings with our extra keys, but then to go “what did I put in that key?”. It happens to the best of us, no matter how used you are with your apps, games, or workflow. A solution for this, which we have seen used a lot for example in the streaming industry, is one of those macro keyboards with an LCD for each key, until you look at the price, and see all your dreams shattered away for yet another overpriced piece of electronics. If only someone made it easy and cheap for us, makers, to DIY or own solution. Well, say no more!

Today we are talking about a very interesting project, the Keybon, designed by Max Kern. It consists of an extremely customizable macro keyboard, at a very reasonable price point. It comes with a companion software, so that its key layout can accompany your workflow, by witching accordingly to the app running in your computer. From the outside, you will see its 9 tactile buttons, with an 0.66” OLED screen integrated into each one.

The cool Keybon, here to save your productivity
The cool Keybon, here to save your productivity

But how does it work? Well, it has two possible modes:

  • In standalone mode, it is basically a simple HID keyboard, showing its preconfigured functions on the buttons
  • With the companion software (which is for Windows only), allows you to create and customize your own keyboard layouts and even assign them to any application present on your computer. By monitoring the application in focus at the moment, the companion app then communicates via a virtual COM port with the Keybon to send the respective layout to the device and it in turn replies with the keys pressed

We already talked a lot about its functionality, now it is time to take a peek at the hardware: the Keybon is connected via USB (obviously) with the computer, and the brains of the operation had to be chosen carefully, due to the necessary RAM to display the images on the 9 OLED screens. Therefore, an STM32F1 with 20kB of RAM was used, which is officially compatible with the Arduino environment. Then, the 9 OLED screens are placed carefully on top, with mechanical switches and a cool casing. Since this is an open source project, you can access everything on GitHub, from the layout and STL files to the code, which allows you to either replicate it or tinker around it to make it even more to your liking. You can even personalize the companion app, which is a very nice touch from Max Kern. Laslty, we think this is a very cool project that can help your productivity and save you a lot of money in the process.

Banana Pi BPI-M5: A New Player in Multimedia Boards

A common trend with the Pi-branded boards, is that they are starting to stir away from the given name and getting their own territory. We have seen that recently with the Orange Pi series, and the new Banana Pi BPI-M5 is another good example of it. But what SinoVoip Co. has in store for us this time?

The Banana Pi BMI-M5 is released after an 18-month stint of its predecessor, the Banana Pi BPI-M4, which was very well received by the maker community, and we think the BPI-M5 will not be an exception in this regard. Regarding its capabilities, we can classify it as somewhere among the lines of the Raspberry Pi 4 and the Odroid C4, with the latter actually using the same Amlogic S905X3 processor. From the outside, you can see the interesting I/O packed into this board, with USB 3.0, ethernet, HDMI, audio jack, and power via USB Type-C, so we are very well served in that regard.

But what about specifications, is there anything to put it above its competitors, or the opposite? Let us take a look at them:

  • Amlogic S905X3 Quad-Core Cortex-A55 ARMv8.2-A 64-bit processor, clocked at 1.5 GHz
  • ARM Mali-G31 MP2 GPU
  • Memories: 4 GB LPDDR4 RAM + 16 GB eMMC on-board Flash and Micro SD card slot
  • Connectivity: Gigabit Ethernet (10 / 100 / 1000 Mbps), and optional USB Wi-Fi dongle
  • Video: HDMI 2.1 output (up to 4K@60Hz with HDR, CEC, EDID)
  • Audio: 3.5 mm audio jack and HDMI digital output
  • Peripherals: 4x USB 3.0 ports, IR, switches (reset, power and U-boot) and LEDs (power and activity status)
  • GPIO: 40-pin header with 28 GPIO pins (with access to UART, I2C, SPI and PWM) and power (3.3 V, 5 V and GND)
  • Power: 5 V @ 3 A via USB Type-C
  • Dimensions of 92 x 60 mm and weight of 48 grams
  • OS: Android and Linux

As you can see by its specs, it goes about toe-to-toe in every lane with the Odroid C4, but it provides some nice advantages, with the on-board 16 GB Flash memory and the flexible power scheme provided by USB Type-C being the most noticeable ones. You also have access to the wide range of add-ons designed specifically for the Banana Pi series of boards, from which you can find sensors, touch panels, a remote control and other interesting modules. Lastly, it looks like there is already a wide set of documents that can be a nice starting point, if you decide to pick up the Banana Pi BPI-M5. It can serve you well on a wide variety of projects, such as a media center, for example, and you can also take advantage of Android, but you are not limited there. There is a lot you can do with it. Regading the price, you can get it on AliExpress for around $53.

Arduino-compatible shields quicken KNX communication designs

RS Components is now stocking the Arduino-compatible NCN5100ASGEVB evaluation boards from ON Semiconductor.

These evaluation kits include all the components necessary to create smart home and building automation systems based on KNX communication technology. The kits are suitable for use with a broad range of MCUs, and can be plugged directly into existing development platforms.

There are three variants of ON Semiconductor’s NCN5100ASGEVB that use the company’s NCN5110, NCN5121 and NCN5130 KNX certified transceiver ICs respectively. The range of transceivers allows both standard and sophisticated implementations to be achieved. Each transceiver integrates a pair of high-efficiency DC/DC converters. Focused mainly on the supply for the transceiver and the system MCU, the first DC/DC converter outputs a fixed 3.3V. The second converter has an output that can be adjusted from 1.2V to 21V.

The second transceiver is designed to be used for powering peripheral parts such as a relays, displays or other analogue IOs. The power delivery capabilities of these transceivers, along with elevated levels of operational efficiency, with ultra-low bus voltage drop and quiescent current, allows users to experiment with potential opportunities for KNX in more power-hungry applications.

The boards that use the streamlined NCN5110 analogue front-end offer all the timings required to be dealt with by the host MCU. The NCN5121 and NCN5130 versions have additional features added. In addition to the PHY, both these receivers have a MAC layer incorporated to reduce the software development work involved. The high level of component integration provided by the transceivers means that size and BoM costs are kept to a minimum.

The ON Semiconductor NCN5100ASGEVB evaluation boards are available now from RS in the Asia Pacific, EMEA and North America regions.

This proactive stance not only bolsters physical safety measures but also fosters a shared sense of accountability and welfare, ultimately fostering a positive workplace culture where team members feel esteemed and well-supported.

Distiamo is the only hybrid solution in the market that offers two modes of accuracy – ‘fine grain measurement’ for high accuracy (to within 10 cm)  and ‘coarse grain measurement’ for medium-level accuracy (to within 1m). It is an extremely cost-effective system and companies can increase the accuracy they need over time, only where they need it.

Distiamo’s front-end dashboard provides all the useful information you need to customize rules and adapt to company scenarios. It is based on the Arduino IoT Cloud, a proven platform used by millions of people worldwide.

As people’s privacy is also of paramount importance, only relevant data in instances where individuals have been within the distance threshold for too long is captured. The data is then stored anonymously by Distimao, remaining private and confidential to ensure compliance with evolving regulations.

The economic and safety benefits go beyond Covid-19. Other workplace safety applications include person down alerts for medical emergencies (e.g. a heart attack), emergency evacuations and maximum room or venue occupancy. As well as workplace safety, the data measurement and analytics tools can easily be applied to optimise the layout of a factory or workplace to maximize process efficiency e.g. tracking products through a warehouse facility.

Commenting on the launch, Fabio Violante, CEO at Arduino said,

“Our primary focus was to create a solution that helps businesses to get started again by making staff and customers feel confident that their safety is covered. Distiamo provides the flexibility, simplicity and scalability to meet the needs of any type of workplace or venue. We are already using the solution in our office and have extended it throughout the co-working space we share in Turin. Several customers are deploying the solution in some very complex and dynamic environments like cruise ships, to help the cruising industry get back on its feet. I can envision thousands of customer situations in which this solution can be the difference between reopening and being safe or shutting down the business.”

Paolo Bozzola, CEO of Moviri added,

“When it comes to solutions that can impact people’s daily lives, accuracy, responsiveness and privacy are essential. We have been extremely happy to partner with Arduino on this project.  By joining together Arduino’s technological breadth and depth with Moviri’s 20 years’ experience in transforming data into information, we can build extremely effective and pragmatic tools like Distiamo. Every time we meet a new customer the discussion evolves into the countless positive possibilities for the post-COVID scenario.”
