Meet the RFL-Watch: LoRa-Based Text Communicator

Posted on by Emmanuel Odunlade

While adulations were still being showered on his work on the MORPHESP 240, Dr. Philippe Cadic (@Sulfroid on twitter), recently shared progress on another project called the RFL-Watch, via his twitter handle which is usually loaded with reports on the progress of his projects.

Based on the RAK4260, the RFL-Watch is a wearable LoRa communicator device which at the very least is expected to be able to tell time among other features.

The maker community for a while has been clamoring for an integrated Lora-MCU module similar to what is available with the ESP8266, with MCU and communication integrated into a single module. A number of LoRa-STM32 modules from Murata and STM themselves, have in the past seemed like a possible way out, but they require extra effort in RF design and certification, and Murata has a minimum order requirement (above 100 units), all of which puts the modules in a different category to modules like the ESP. The amount of LoRa-MCU vendor solutions in the market has increased, but it’s safe to say one of the few that has truly spoken to the pain point of makers has been the RAK4620 and @Sulfroid is already putting the module to use with this Watch.

The RAK4620, based on Microchip’s ATSAMR34J18B, combines a 32-bit ARM Cortex -M0+ MCU with a LoRa Transceiver in a compact surface-mount package, with key features including; Full support for 862 to 1020 MHz frequency coverage (all LoRaWAN® bands), High level of accuracy and stability (32MHz TXCO), Max Tx Power: 20dBm, Max Sensitivity (SF12 BW125kHz):  -136dBm, 17mA (typical) RX Current, and a rich selection of interfaces( I2C, SPI, ADC, UART, GPIOs).

While the work on the RFL-Watch is still in progress, the watch, asides the primary time-telling functionality, comes with a display, a 240 x 240 pixel, high-DPI, IPS LCD, through which a LoRa based text communication is expected to be implemented.

The project is still evolving and the final destination is still largely unclear, but you can follow the development process by checking out the twitter handle of the good Dr.(@sulfuroid). 

We will also provide you with more information as things unfold. Stay tuned!

Type K Thermocouple Sensor Amplifier Arduino Shield

This is a Type K Thermocouple Sensor Amplifier Arduino Shield that enables an Arduino board to acquire temperatures from a thermocouple of type K. The shield works with a single supply and takes 5V DC from the Arduino board, the output of the circuit is 0 to 4V DC for 0-degree centigrade to 400C. The output of the amplifier is connected to the A0 analog pin of Arduino. A typical application of thermocouples is in boilers, soldering stations, and heaters. Also, 3D printers rely on thermocouples to measure the extruder temperature.

The K thermocouple has usually two wires, made of Alumel and Chromel that need to be connected with special care: no solder, just use a mechanical connection, therefore it is advisable to use special connectors available for thermocouples.

The circuit is built using LTC1049 op-amp and Thermocouple Cold Junction Compensator chip LTC1025. The board also supports other sensors like Type E, J, R, S, and T, however I have tested this circuit with Type K Sensor, jumpers are provided to use, and select other types of sensors.

The LTC1049 is a high performance, low power zero-drift operational amplifier. The two sample-and-hold capacitors usually required externally by other chopper stabilized amplifiers are integrated on the chip. Further, the LTC1049 offers superior DC and AC performance with a nominal supply current of only 200μA. The LTC1049 has a typical offset voltage of 2μV, drift of 0.02μV/°C, 0.1Hz to 10Hz input noise voltage of 3μVP-P and typical voltage gain of 160dB. The slew rate is 0.8V/μs with a gain-bandwidth product of 0.8MHz.

The LT®1025 is a micropower thermocouple cold junction compensator for use with type E, J, K, R, S, and T thermocouples. It utilizes wafer level and post-package trimming to achieve 0.5°C initial accuracy. Special curvature correction circuitry is used to match the “bow” found in all thermocouples so that accurate cold junction compensation is maintained over a wider temperature range. The LT1025 will operate with a supply voltage from 4V to 36V. The typical supply current is 80mA, resulting in less than 0.1°C internal temperature rise for supply voltages under 10V. A 10mV/°C output is available at low impedance, in addition to the direct thermocouple voltages of 60.9mV/°C (E), 51.7mV/°C (J), 40.3mV/°C (K, T) and 5.95mV/°C (R, S). All outputs are essentially independent of power supply voltage

Features

  • Supply 5V DC
  • Thermocouple Sensor: Type K
  • Output 0 to 4V DC

QD7-0-SD/QD50-0-SD Position Sensing Detectors

Posted on by mixos

OSI Optoelectronics’ position sensing detectors are ideal for light beam nulling and position applications

OSI Optoelectronics’ QD7-0-SD and QD50-0-SD are quadrant photodiode arrays with associated circuitry to provide two difference signals and a sum signal. The two difference signals are voltage analogs of the relative intensity difference of the light sensed by opposing pairs of the photodiode quadrant elements. In addition, the amplified sum of all four quadrant elements is provided as the sum signal. This makes the QD7-0-SD or QD50-0-SD ideal for both light beam nulling and position applications. With these detectors, very precise light beam alignments are possible and the circuit can also be used for target acquisition and alignment.

  • Precise light beam alignments
  • Beam nulling
  • Two difference signals
  • Sum signal
  • Position measuring
  • Beam centering
  • Targeting acquisition
  • Guidance systems

Detector-Filter Combination Series Planar Diffused Silicon Photodiodes

Posted on by mixos

OSI Optoelectronics’ detector-filter combination series incorporates a filter with a photodiode to achieve a tailored spectral response in a multitude of standard and custom combinations. All detector-filter combinations can be provided with a NIST traceable calibration data specified in terms of amps/watts, amps/lumen, amps/lux, or amps.

The PIN-10DF is a 1 cm2 active area, BNC package detector-filter combination optimized to achieve a flat responsivity from 450 nm to 950 nm. This is the spectral response required for radiometric measurements. This type of detector has several advantages over thermopile, such as sensitivity, which is about a thousand times higher, as well as 10 times more stability.

The PIN-10AP is a 1 cm2 active area, BNC package detector-filter combination which duplicates the response of the most commonly available optical aid, the human eye. The eye senses both brightness and color with response varying as a function of the wavelength. This response curve is commonly known as the CIE curve. The AP filters accurately match the CIE curve to within 4% of the area.

The PIN-005D-254F is a 6 mm2 active area, UV enhanced photodiode-filter combination which utilizes a narrow bandpass filter peaking at 254 nm.

Nano: spot welding just got easy and affordable

Posted on by Emmanuel Odunlade

One of the major focuses of the maker movement since time immemorial has been the development of a makeshift version of tools with the goal of making them cheaper and more accessible. This focus has been more pronounced in recent times with several tools like CNC and 3Dprinters being all open-source, decentralized, and affordable to regular folks. To take things further to more machine tools, Canada-based battery refurbishing company; RePowered Batteries, recently announced the launch of their Nano Ultra-Compact Spot welder, which is aimed at making welding more accessible to hobbyists.

Sharing the reason behind the development of the Spot Welder, the team at RePowered Batteries said that the primary “goal is to make a no-hassle and affordable welder” that surpasses the current welders in the market by being both cordless (no external power supply required) and more efficient and safe compared to similar devices on the market.

The Ultra-Compact Spot Welder is comprised of a small built-in DC-DC power regulator, high-quality supercapacitors, and a welding control board on a PCB with 15x more copper than standard PCB, all packaged in a 3D-printed housing, with a selection of welding tips and air-cooled electrodes as consumables.

Built with versatility in mind, unlike other similar solutions in the market, the Spot Welder allows users to weld up to 0.15mm solid nickel. A table showing how the weather further compares with similar devices in the market is shown below:

While the goal is to make the device handy and untethered, one way to power the device is via the use of a 9v external power supply which could be useful, when you need to get things done, fast. However, if you are not in a hurry and not out of battery power, there are several other ways to power the devices including; power over USB or by hooking up a single 18650 battery cell to it.

The Kickstarter campaign for the device was launched a few days back and with just 21 days left, the project has raised up to $12,400 surpassing its initial goal of $3,047 by up to 400%. The device was designed in a modular form and the crowdfunding campaign provides users with the opportunity to buy them in parts, separately, or as a kit.

More information on the SpotWelder, the crowdfunding campaign, and perks, can be found on the project’s Kickstarter page.

AirBolt® GPS – The Tiny GPS Tracker You’ve always wanted

Posted on by Emmanuel Odunlade

From pets wandering away and ultimately getting lost, to keys and other items getting misplaced, the desire to, at all times, be able to tell the location of things that are important to us is a priority to everyone. Several GPS tracking solutions exist on the market with small form factors and superb performancε thanks to advancements in communication and GPS technologies. However, with innovation, there is always room for improvement and greater heights to scale, and that’s exactly what Melbourn based AirBolt is doing with the launch of its new GPS tracker; the AirBolt® GPS which debuted on Kickstarter a few days ago.

AirBolt takes pride in its user-led design process as displayed in the AirBolt Smart Travel Lock which was released a while back, and the process was adopted for the development of the AirBolt® GPS. According to the AirBolt team, A total of 6 factors/features were considered and set as priorities during the design of the new GPS;

  • Small Form Factor
  • Long Battery Life
  • Customizable Alerts
  • Discrete Outlook
  • Shared Access
  • Global Tracking
  • Sturdy and Waterproof

Tailoring the design towards this features/goals led the team to the development of a small, only 37mm x 34mm x 11mm (1.45″ x 1.34″ x 0.43″) and VERY lightweight (approx. 21 grams, 0.75oz), LTE-M/NB-IOT enabled device, based on GPS rather than Bluetooth as in other devices.

The small and discrete nature of the device means it can be hung from the collar of a pet or slipped discreetly in a pocket/bag or be used as a keyholder.

Implementing location over LTE-M/NB-IoT, which are low-powered cellular networks, helps users leverage in the latest communication solutions while saving big on power, ensuring the device lasts for a long time before recharge is needed.

Some highlight features of the AirBolt® GPS as documented by CNX-software include:

  • SoC(s)
    • Unnamed, but considering Nordic Semi is listed as a partner it should be nRF9160 SiP with Arm Cortex-M33 MCU core, 1024 KB flash, 256 KB SRAM, NB-IoT, LTE Cat M1, and GPS connectivity
    • There’s also Bluetooth 5.1 so one of the nRF52 chips might also be included.
  • Connectivity
    • Bluetooth 5.1 with long-range and direction-finding support
    • Cellular – Worldwide support via NB-IoT and LTE Cat M1 (aka eMTC or LTE-M)
    • GNSS – GPS
  • Sensors – Accelerometer, temperature sensor
  • Misc – Alert Button, LED, a loud buzzer
  • Battery – Up to 12 months of battery life; rechargeable via USB-C port
  • Dimensions – 37 x 34 x 11 mm(ABS + anodised aluminum)
  • Weight – 21 grams
  • IP Rating – Not listed, but the tracker is said to be waterproof up to 1 meter for up to 30 minutes (IPX7)

The AirBolt® GPS has shown potentials of being a top-notch product as the Kickstarter campaign has already raised more than 200% of its goal with over 3,105 backers.

More information about the product and the Kickstarter which will be closing in about a week’s time can be found on the project’s campaign page. 

DipDuino – An Arduino clone made for breadboarding
