Little Bee, affordable high-performance current & magnetic field probe

Posted on 3 February, 2021 by Tope Oluyemi

A campaign for a current probe called Little Bee was launched on Crowdsupply. Little Bee is an affordable and high-performance current probe and magnetic field probe that enables you to debug and analyze electronic devices more effectively. This device comes in handy because current probes available today are expensive, therefore having a limited number of users. Current probes are gaining ground today because of the popularity of power electronics like electric vehicles, alternative energy, and high-efficiency power supplies. Regarding the aim of the project, the company says:

“We hope to make the world of power electronics accessible to more people by delivering a much-needed piece of test equipment as open hardware and at an affordable price.”

Little Bee can function as a traditional current probe, providing isolated measurements of the current in a wire with higher accuracy, and It can also measure currents over a wide bandwidth: from DC to the MHz range. Thanks to its Anisotropic Magneto-Resistive (AMR) magnetic sensor, Little Bee’s performance can be compared to other current probes based on fluxgate magnetometers, and probes with hybrid features that offer AC current transformers with DC hall effect sensors. Little Bee offers the same level of performance, but with a much lower cost.

The AMR sensor functions by sensing magnetic fields, producing a voltage proportional to the magnetic field strength. It features a clip, which enables current sensing by translating the current in a wire into a magnetic field. It is also equipped with a ferrite toroid with an air gap in which the sensor tip rests. The synergy between the current in the wire and the magnetic field in the air gap varies little as the wire moves around the center of the toroid. This enables accurate current sensing despite variations in the test setup.

The output of the AMR sensor is amplified by low noise, high bandwidth amplifier to provide the correct signal level for oscilloscopes. The amplifier is controlled by a PIC microcontroller, enabling automatic zeroing and offset adjustment as well as gain and bandwidth switching. Little Bee is easy to use. It can connect to any oscilloscope with a standard 1 MΩ input impedance via the provided SMA to BNC cable. You don’t have to carry out much configuration, it is ready for use, you just flip the power switch and it comes on. It features two buttons that are used to zero the probe and to cycle through bandwidth and gain options.

About accessibility, the company says:

“It is important that the open source community have access to high-quality tools. A desire to make a once prohibitively expensive technology accessible to a wider audience inspired the creation of the Little Bee. All the project files are hosted on GitHub under the Creative Commons Attribution-ShareAlike 4.0 license.”

Production will be carried out in different parts. The main Little Bee PCB will be assembled by MacroFab situated in USA, and the mechanical parts will be 3D printed out of Multijet FusionPA12 by Sculpteo. Also, the final mechanical assembly of the probe, firmware flashing, and calibration, will take place in-house before shipping all finished units to Crowd Supply’s fulfillment partner Mouser Electronics, who will distribute them to backers.

Features

Adjustable bandwidth (10 MHz and 1 MHz)
Adjustable gain (1x and 4x)
SMA Output Connector
Connects to any standard 1 MΩ impedance oscilloscope input
Powered by a single AA battery (4 hour battery life)
Automatic zeroing
Bandwidth: DC – 10 MHz
Sensitivity: 0.25 Volts/Amp
Max Current: +/- 5 A

Watchy: Pebble-like SmartWatch with Bluetooth and WiFi 4 Connectivity

Posted on 3 February, 20213 February, 2021 by Saumitra Jagdale

The Watchy e-paper smartwatch reminds us of the Pebble e-paper smartwatches, which came with a Bluetooth interface for connection with personalized Android and Apple mobile handsets. It used to support SDK for customization of the features according to the user requirements. However, the Pebble had closed its smartwatches after the Fitbit acquired the company in 2016.

Watchy seems to be a closer resemblance to Pebble-like smartwatches, but instead of a full-color OLED display, it comes with a monochromatic 1.54-inch e-paper display. The screen has a resolution of 200 x 200 pixels and is offcource low power. Hence, this makes the Watchy smartwatch readable from different viewing angles. Although, it has one drawback that it does not include a backlight or sidelight for seeing time in the dark.

Key Features of Watchy Smartwatch:

Microcontroller ESP32-PICO-D4
USB-Serial CP2104
E-Paper Display GDEH0154D67
Display Connector AFC07-S24ECC-00
3-Axis Accelerometer BMA423
Real-Time Clock DS3231
Battery LiPo Battery 3.7V 200mAh 402030
LDO Voltage Regulator ME6211C33M5G-N
Battery Connector BOOMELE 1.25T-2PWT
Micro USB Connector U-F-M5DD-Y-L
Tactile Buttons K2-1114SA-A4SW-06
Vibration Motor 1020
PCB Antenna SWRA117D

Watchy comes with Espressif Systems ESP32-PICO-D4 system-in-package with ESP32 dual-core processor with Bluetooth LE 4.2/5.x and WiFi 4 connectivity. It also features wide viewing angles and 4MB SPI flash for interfacing. BMA423 is the 3-axis accelerometer functioning as a sensor for gesture detection and activity tracking. Talking about the power specification, it has a 200 mAh battery fit for 5-7 days for timekeeping provided without WiFi. Whereas with a WiFi connection it can only last 2-3 days.

“The Watchy library depends on other open source libraries to drive all of its hardware, some of which have been wrapped in Watchy.h to provide a framework for building watch faces and apps.”

Watchy supports GxEPD2 which is an Arduino Display Library for SPI E-Paper Displays. Also, It works with SPI communication needed to control Watchy’s E-Paper display. This library depends on the Adafruit GFX library, which provides the graphical interfacing methods for customized images, shapes, and text. It also allows functions such as a display.drawRect() for drawing shapes, display.drawBitmap() for drawing images.

Watchy’s software, hardware, and documentation are fully open source under MIT license and OSHWA certified. Watchy smartwatch is available on Tindie for $49.99 but at this point in time, it is out of stock. You can still register your email address to join the waiting list to purchase the smartwatch in the next lot. Images and technical specifications have been taken from Tindie’s blog and Watchy’s documentation.

Function-rich resettable eFuse for consumer goods

Posted on 3 February, 2021 by mixos

Resettable eFuse maintains high safety through repeated use with adjustable over-voltage protection plus flagging capabilities.

Expanding its range of advanced eFuse ICs, the TCKE712BNL from Toshiba Electronics Europe GmbH ensures that the highest degrees of safety are always maintained. It is targeted at a broad spectrum of different consumer electronics goods – including cameras, cordless cleaner and power tools, cleaning robots, server, smart, speaker, thermostats and wireless chargers.

While conventional fuses, such as glass tube and chip fuses, protect power supply lines by breaking if there is excessive current, eFuses provide a much more effective alternative. Unlike outdated conventional fuses, they are designed to support repeated use (being automatically reset by an internal logic signal). These devices also offer much faster responsiveness and have a greater breadth of built-in protection functions.

Exhibiting a 53 mΩ on-resistance and with a trip time of only 320ns, the TCKE712BNL covers an input voltage range spanning from 4.4 V to 13.2 V. It is possible to adjust this device’s over-voltage threshold to fit with the specific application requirements. In addition, over-current (also adjustable), over-temperature and short-circuit protection mechanisms have all been included. A flag function transmits an external signal that will alert engineers of possible faults in the circuit design, so they can be addressed early on in the development process. Thanks to the reverse current blocking feature, there is the scope for this device to be employed in multiplexed systems.

Toshiba’s TCKE712BNL eFuse is supplied in a compact WSON10 package measuring just 3.00- x 3.00-mm, thereby taking up minimal board real estate.

Wiretrustee designs a Four-port SATA Raspberry Pi CM4 carrier board for low-power NAS

Posted on 2 February, 20216 February, 2021 by Emmanuel Odunlade

Wiretrustee has designed an ultra-compact x4 SATA Raspberry Pi CM4 carrier board with up to 220MB/s throughput for NAS applications.

“After watching a couple of videos from Jeff Geerling I thought I might try it out and build my own SATA carrier board for the CM4,” said an unnamed representative of the company who we suspect to be the brain behind the project. “I’m not chasing high IO therefore a limitation of PCIe x1 wasn’t a real problem to me. I still think you could have a decent speed with only one lane especially for my case where I anyway will connect and download/upload files from/to the home network via the internet (mobile mostly). So I made a decision and started building my own carrier board for CM4 since the alternative was a huge IO board with the PCIe card or some custom board but again with a PCIe card.” he added.

The Raspberry Pi compute module 4 carrier board features a number of ports for connectivity and power alongside other accessories like a four-pin fan header, a real-time clock, and a front-panel control board. There’s also a Marvell 88SE9215 controller which is responsible for the back and forth signal conversion between PCIe and SATA.

Board specifications:

4x SATA 2.0 ports
USB-C Power 5V 5A (max)
1x microSD slot
1x GbE port
2x USB 2.0 ports
HDMI 2.0
1x 4-pin 12V fan header
RTC + battery backup
LED Control board connected via FPC cable to the main one for a nicer NAS case design (includes SATA status LED, Power button and Reset button)
Dimensions: 100 mm x 100 mm

The board has so far attracted some positive feedback from the community and a number of people have expressed their desire to purchase one when it is finally out for sale. They think the purpose and the balance in the board design are really good and that the designer obviously “leveraged on the size, connectivity, and format of the CM4, to build a focused, small implementation.”

The developer is also pleased with the design results he has gotten so far and he is already considering making it available on Crowdsupply for mass production, though he is not very sure about the certification requirements for now. He also made it clear that there is no fixed price attached to the board yet but judging from the total cost of production which includes the PCB, components, cost of assembly, and import taxes, the cost of the board might just fall within the €100-140 range and he wouldn’t compromise on the quality of the materials used. Hopefully the board should come along with a really nice case and a proper heatsink.

Further details are available on Reddit or on the Wiretrustee website.

Epishine’s world unique solar cell provides power indoors down at ~2 uW/cm²

Posted on 2 February, 202121 December, 2021 by mixos

Now it’s here. Epishine’s ”light cell” can change how we power small electronics – a thin and flexible organic solar cell that can be integrated into sensors, consumer electronics, and other low power devices to reduce or eliminate the need of batteries.

“We are very proud to have taken the results from more than 25 years of research into this product. What makes it even better is that we have also developed a production process that is scalable into large volumes. This makes us one of the global leading actors in printed organic solar cells”,

says Anna Björklou, new CEO of Epishine.
‍
Epishine’s light cells are non-toxic, based on organic electronics, and encapsulated in recyclable plastics. The unique scalability is due to the fact that the entire manufacturing process is based on different printing techniques, roll-to-roll. The thin and flexible cells can easily be integrated into typical plastic-based electronics housings.

“We can now offer a product that completely redefines the possibilities for anyone developing low-power wireless devices for instance for the growing IoT and PropTech markets. You can now develop products that don’t dependent on expensive battery replacements”,

says the sales director Jonas Palmér, Epishine.

The global digital transformation requires more and more dataflow between the physical and digital worlds. This will rapidly lead to a countless number of small sensors and displays, that today are powered by batteries. This is not sustainable, neither from an environmental perspective nor from a maintenance perspective.

Features:

Ideal for powering wireless indoor low-power applications, such as IoT devices, various sensors, etc.
Made from low-cost organic materials.
Reduces environmental impact by up to 99% and cuts maintenance costs by replacing batteries in wireless devices.
Intended for use indoors and under indoor light conditions, e.g. office, supermarket, home, etc.
Flexible, compact and lightweight design with 0.2 mm thickness.
Available in 6 standard sizes: 20, 30 and 50 mm with 6 or 8 cells.
Semi-transparent module area for easy integration.

Epishine’s cutting-edge light cell is optimized for ambient light indoors. All electronic devices that today are powered by small batteries that last for a year or more can potentially be powered by harvesting ordinary indoor light with this innovation.

The new Swedish light cell that Epishine is starting to sell today is manufactured in an industrial process with capacity for the world market.

Melexis expands IMC-Hall® current sensor portfolio exceeding measurement

Posted on 2 February, 2021 by mixos

Melexis, a global microelectronics engineering company, has introduced the MLX91216 XHF extra high-field current sensor, extending the ease and accuracy of its unique IMC-Hall® technology into high-current measurement for emerging automotive applications.

Capable of measuring current to beyond 2000 A, the MLX91216 XHF is suited to redundant monitoring of battery-management systems (BMS), over-current detection in smart fuses, and measuring phase currents in traction inverters and boost/recuperation inverters. With user-programmable filtering to adjust resolution, response time, and bandwidth for optimum signal-to-noise ratio, the sensor features built-in diagnostics, including broken-wire detection.

The SOIC8 surface-mount device contains Melexis’ patented Integrated Magnetic Concentrator (IMC) that enables accurate contact-free measurement of busbar current in combination with a simple U-shape magnetic shield. When mounted on a PCB, the sensor is positioned over the busbar, within the shield, allowing easier assembly than conventional Hall sensors. What differentiates the proven IMC-Hall® technology from coreless solutions is that position is much less critical. The design can accept more mechanical movement because the measurement is not dependent on a magnetic field gradient. Other technologies that are can result in very severe bus bar machining causing important thermal hot spots. On the other hand, IMC-Hall® technology carries the advantages of coreless technologies, so it lends itself to smaller assemblies with surface mount package solutions. This avoids the use of more complex through-hole packages that often require specific lead bending/forming native to core-based solutions.

The MLX91216 XHF extends the family of Melexis IMC-Hall® sensors that provide accurate, high-speed current measurement for a wide range of automotive and industrial applications.

MLX91216 High field (HF) versions: 200 to 600 A
MLX91216 Very High Field (VHF) versions: 400 to 1200 A
MLX91216 eXtra High Field (XHF) versions: 800 to 2000 A

Available now, the MLX91216 XHF is AEC-Q100 Grade-0 qualified for automotive applications and operates over the temperature range -40 °C to +150 °C. The sensor has a wide measurement range from ±20 mT to ±350 mT with linearity down to ±0.2% full scale, 2 μs response time, and high thermal stability with offset drift below 5 mV and sensitivity drift within 1%.
