V-Powerbuds Pro TWS Earbuds Support Heart Monitoring & Oxygen Tracking (Crowdfunding)

Vimai V-Powerbuds Pro Multi-function Sport Earbuds Vimai’s V-Powerbuds Pro TWS (True Wireless Stereo) earbuds are multi-function wireless earbuds. In the past, we had reported on the Misfit Specter Bluetooth earbuds that could track fitness input, such as steps, calories, and sleep duration. V-Powerbuds Pro also tracks heart rate, oxygen, and respiration, and supports online & offline voice control. The Component Basics The V-Powerbud Pro are TWS earbuds and have a built-in pulse oximeter to capture heart rate and oxygen levels right from within the ear. The hook design holds the earbuds tightly in place, within the ear, to get an accurate measurement independent of the effects of light. Other types of fitness tracking devices like those located on the wrist, can be affected by light. The Difference From Other Sport Earbuds Although the uses during exercise aspect of this wearable are probably more likely to be a selling point, the voice control features make the V-Powerbuds Pro an attractive alternative …

Lindenis V536 SoM & SBC Targets 4K Camera Applications

Lindenis V536 Specifications

Back in summer 2018, we wrote about Lindenis V5 single board computer based on Allwinner V5 quad-core Cortex-A7 processor with two MIPI CSI connectors and designed for 4K cameras. Allwinner has now come up with a new 4K camera processor very similar to V5, since Allwinner V566 comes with two Cortex-A7 cores, and a single MIPI CSI interface, and Lindenis designed a new SBC based on the new processor using a SoM + baseboard design instead. Lindenis V536 specifications: SoM SoC – Allwinner V536 dual-core Cortex-A7 processor @ 1.2 GHz; 4K H.265/H.264 video encoding & decoding @ 30 fps; 28nm process System Memory – 1GB DDR3 Storage – SPI NOR flash or SPI NAND flash, bootable MicroSD card Video Output – Micro HDMI 1.4 port Video Input – MIPI CSI connector Audio – Digital microphone Connectivity – 802.11b/g/n/ac Wi-Fi 5 & Bluetooth 4.2 via AP6255 Baseboard Interface  – Castellated holes Power Supply – 5V/2A via micro USB port or castellated …

TIL: Some 9V Batteries can be Recharged with a Simple USB Cable

9V Battery USB

9V batteries are/used to be popular for Arduino projects, as they can easily be connected via the power jack of the board. But now that most recent Arduino boards are powered by 5V via a USB Type-C port or Vin in, those are not an option. I thought I found a solution when I saw the following tweet earlier today which looks to provide a convenient way to connect a 9V battery to devices powered by USB. accidentally ran into another cursed adapter: 9v battery to USB pic.twitter.com/laKjIi6wUy — foone (@Foone) January 20, 2020 I was unable to find details about the board, but I suppose the chip close to the USB connector is a 9V to 5V regulator (e.g. LM7805), so this would indeed output 5V. Just don’t expect to fully charge your phone with it, as a typical 9V battery has a 500mAh capacity. [Update: It’s on Retrokits, but out of stock] If you are interested in unusual …

Piksey Atto is a Tiny Arduino Compatible Board with Castellated Holes (Crowdfunding)

Piskey Atto

Atto is a unit prefix in the metric system denoting a factor of 10−18, so it’s unsurprising that at least one company, namely Nionics, made a small Arduino compatible board called Atto. But somebody must have forgotten to do a web search, as BitsNBlobs Electronics created their own tiny Arduino compatible board, also named “(Piksey) Atto“, and based on the same Microchip ATmega32U4 8-bit AVR MCU. But there are some important differences as we’ll see below. Piksey Atto specifications: MCU – Microchip ATmega32U4 8-bit AVR microcontroller @ 16 MHz with 32KB flash, 2.5KB SRAM, 1KB EEPROM Expansion – 18x castellated through holes for 11 digital I/Os, 4x PWM, and 4x analog inputs, USART/SPI/I2C USB – Micro USB port for power and programming Power Supply – 5V via micro USB port Dimensions – 20.32 x 12.7mm Weight – 1.3 grams Piksey Atto is about twice the size and weight of Nionics Atto, lacks LEDs, and a reset button, but offers breadboard …

MarsCat is a Bionic Cat Powered by Raspberry Pi 3 (Crowdfunding)

MarsCat

Elephant Robotics MarsCat is a robotic cat that tries to mimic the behavior of actual cats through artificial intelligence. It can have a life of its own roaming the house, and you can also interact with it as it will play with toys/teasers through its camera, and you can send voice command to ask it to walk, run, look at you, be quiet. etc… but the trick is that it may not always obey like a real cat, and its personality will evolve depending on how you interact with it. Beside being a bionic pet, MarsCat can also be used to teach/learn robotics as the company will release an open-source SDK allowing you to change the Python code running on the Raspberry Pi 3 board powering the cat, and access API’s to control the camera, microphone, touch sensors, as well as the 16 servos connected to a Microchip ATMega2560 MCU via two servo boards. Visual programming for the robot will …
