AI-Powered Vizy Camera is Live on Kickstarter

Charmed Labs, a company from Texas, has unveiled its AI-driven Vizy camera. This little camera takes benefit of its onboard deep learning neural networks for objects, people, and animal detection. Vizy only utilizes its single, internal Raspberry Pi 4 for processing and classifying the input images locally without the help of any host PC. One such AI-powered camera was MegaAI – a 4K, 60 FPS camera solution for computer vision.

Inside view

It uses a Sony IMX219 image sensor, the same hardware found in the Pi Camera 2.1 module which enables it to take advantage of the same drivers and software. For the camera peripherals, we find an I/O header, on/off power button, 1X USB Type-C port, 2X HDMI ports, and a stereo-out jack. There is also a pair of USB 2.0/3.0 ports, an Ethernet port, a light mount, an RGB LED, a 12V power jack, and an internal fan for cooling purposes.

The camera comes with a very user-friendly web-based interface. This makes it so easy to access from any mobile or computer device with a web browser. Vizy is entirely programmed in Python with support for TensorFlow, OpenCV, PyTorch, and other libraries to take its AI-based detection to another level.

This AI camera is loaded with some ready-to-run projects out of the box. It has a birdfeeder app that can recognize different species of birds on a birdfeeder. It can distinguish between other birds or animals which may raid the bird feeder and alert the user or given the opportunity, Vizy can control a sprinkler valve with its high-current I/O and send a harmless squirt of water. There’s also a custom scientific app that can track objects in motion and can provide valuable data about their position, speed, and acceleration within each frame. It can also be helpful with remotely monitor and feed household pets.

The Motionscope feature

Charmed Labs is currently crowdfunding Vizy on Kickstarter with pledges starting at $229. For $229, it promises a 2GB Raspberry Pi 4, 32Gb Ultra MicroSDXC card with all necessary software pre-installed. There is also a 12-megapixel camera and a wide-angle lens. It even comes with a switchable IR filter for day/night use, I/O connectors and accessories, and a 25W AC power supply. The estimated delivery by the company is in Jan 2021, shipping is available anywhere in the world.

ADAFRUIT QT PY – SAMD21 DEV BOARD WITH STEMMA QT

As a maker, you want to have the coolest, smallest, easy to program boards, and on top of that, you want to get good performance, plus a versatile set of features at a cheap price point. So that they fit everywhere and do not break your bank. Well, look no more, as the QT Py promises to deliver this and much, much more!

The QT Py is a diminutive development board produced by Adafruit, using the SAMD21 chip (also found in the popular GEMMA M0 and Trinket M0 boards, also from Adafruit). It comes with the innovative, plug-and-play STEMMA QT connector, which allows you to chain a bunch of compatible peripherals (sensors, LCD’s, among others) into each other easily and control them through the I2C bus, leaving you with a compact, a fuss-free project without needing to touch a soldering iron. Pretty cool, right? It is compatible with a wide collection of peripherals, either from Sparkfun, Adafruit or Grove (requires a small adaptor), they got you covered! This will overall speed up the development of your next idea, making prototypes even easier and smaller.

But regarding specs, what are we looking at? Let’s take a look:

  • ATSAMD21E18 processor, based on the 32-bit ARM Cortex-M0+, clocked at 48 MHz with 256 KB Flash and 32 KB RAM memories
  • 1x 10-bit analog output, which can be used to play audio clips in Arduino (CircuitPython does not support audio clips storage)
  • 9x 12-bit analog inputs, 9x PWM ouputs, 11x GPIO pins
  • Hardware I2C (with STEMMA QT plug-and-play connector), SPI, I2S and UART
  • 6x Capacitive touch with no additional components required
  • 3.3 V regulator with 600 mA peak output
  • USB type C connector, on-boad RGB NeoPixel LED and reset button
  • Optional SOIC-8 SPI Flash chip on the bottom
  • Native USB supported by every OS, can be used as a USB serial console, among other things
  • Really small form factor, pinout compatible with Seeed Xiao

Regarding software, the QT Py from Adafruit can be used with Arduino IDE and CircuitPython, making it easy for you to program in your favorite environment. If storage is an issue, there is also a SOIC SPI flash that you can solder onto the bottom pads of the PCB, so you are not limited there.

Regarding the price, you are looking at no more than $6.00 for the QT Py without the optional SPI Flash. If you are looking to expand its memory, they also sell a recommended Flash for an extra $1.25. Currently, both of them are out of stock, so this board is making quite a fuss. What do you think, will you pick it up?

0 to 10 V Adjustable Lab Power Supply with Current Control

The circuit presented here is a very simple and easy to build Lab Power Supply. The output of this power supply is adjustable from 0 to 10V DC, and it has current limit control up to 3A. Two Trimmer potentiometers are provided to adjust the voltage and current. The input supply is DC 12V to 18V 3A or AC12V /3A. The screw terminals help to connect the input and output connections, and a large area on PCB provided as heat spread so no external heatsinks required. The power supply also includes over-temperature protection. The board is built using 2 x LT3083 chips, U1 is used as current source and U2 provides adjustable output voltage.

The LT®3083 is a 3A low dropout linear regulator that can be paralleled to increase output current or spread heat on surface mounted boards. Architected as a precision current source and voltage follower, this new regulator finds use in many applications requiring high current, adjustability to zero, and no heat sink. The device also brings out the collector of the pass transistor to allow low dropout operation— down to 310mV—when used with multiple supplies. A key feature of the LT3083 is the capability to supply a wide output voltage range. By using a reference current through a single resistor, the output voltage is programmed to any level between zero and 23V (DD-PAK and TO-220 packages). The LT3083 is stable with 10μF of capacitance on the output, and the IC is stable with small ceramic capacitors that do not require additional ESR as is common with other regulators. Internal protection circuitry includes current limiting and thermal limiting.

New PIC24F MCUs are AEC Q100 Grade 1 Qualified

Low power MCU family offers power-saving peripherals, hardware safety, and secure code protection

System developers of battery-powered and other power-conscious designs with and without LCD displays can now easily add an array of innovative features using a new line of PIC® eXtreme Low Power (XLP) microcontrollers (MCUs) from Microchip Technology Inc. Packed with 14 types of Core Independent Peripherals (CIPs) that operate outside the Central Processing Unit (CPU) for power savings, the PIC24F GU and GL families of MCUs feature the CIP called LCD with Autonomous Animation.

Most display applications involve a few common animations like periodically alternating between displays and blinking of pixels to indicate operation. By using the integrated LCD driver with autonomous animation, developers can offload most of these simple animation routines from the CPU, allowing animation even in doze, idle or sleep modes for optimal power savings. To assist in quickly designing such display interfaces, the new MCUs come with MPLAB® Code Configurator (MCC) support. This graphical programming environment with LCD display designer helps eliminate the meticulous and time-consuming task of mapping the pins and segments.

“The latest family of PIC MCUs adds new hardware features that improve low power performance, code protection and reliable operation in applications across multiple segments,” said Joe Thomsen, vice president of Microchip’s MCU16 business unit. “This scalable family of devices enable applications from cloud-connected low-power IoT nodes and sensor systems to automotive, consumer and industrial automation applications and helps developers easily add displays, robustness and security to their designs.”

The new MCU families are also designed to make it easy to increase the security of an application, whether it is connected to the Internet or a standalone system. Microchip’s CodeGuard™ security Flash protection enables segmenting memory into boot and general segments to implement memory access restrictions. The Flash memory is configurable as One Time Programmable (OTP) via Microchip’s In-Circuit Serial Programming™ (ICSP) write inhibit feature that disables any further modification of the Flash through external programmers/debuggers. Together with these features, security can be further enhanced using Microchip’s CryptoAuthentication™ devices as a companion chip to add secure over-the-air updates and pre-provisioned cloud services. Lastly, the MCUs are supported by CryptoAuthLib, 16-bit bootloader, USB and many application libraries in MCC to significantly reduce development time and complexities.

The integrated hardware safety features of the PIC24F GU and GL families enable reliable operation in harsh environments through Flash Error Correction Code (ECC), Deadman Timer (DMT), Windowed Watchdog Timer (WWDT), Fail-Safe Clock Monitor (FSCM), Configurable High-Low Voltage Detect (HLVD) and Cyclic Redundancy Check (CRC).

Capable of operating in harsh environments, the MCU families are ideal for automotive, industrial and consumer applications. They feature an extended operating temperature of up to 125 °C, are automotive AEC Q100 Grade 1 qualified and have a diagnostic library for IEC 60730 (household appliances) Class B safety standards.
