Review of myCobot 280 Pi robotic arm with Python and visual programming

myCobot 280 Pi is a versatile robotic arm with a 6 degree of freedom design. It was developed by Elephant Robotics using the Raspberry Pi 4 board as the main controller. The robot is compact and delivers stable operation making it ideal for confined spaces. It can also be programmed in a variety of languages, is easy to use, and offers a lot of features. It is suitable for those who are interested in learning how to program a robotic arm controller and for engineering projects. Unboxing myCobot 280 Pi The myCobot 280 Pi arm has a working range of 280 mm, weighs 850 grams, and can handle a payload of up to 250 grams. It is powered by 6 servo motors, one for each degree of freedom, and comes with a 5×5 matrix LED display, and supports LEGO parts as well. Controlled by a Raspberry Pi 4 single board […]

TinyML-CAM pipeline enables 80 FPS image recognition on ESP32 using just 1 KB RAM

The challenge with TinyML is to extract the maximum performance/efficiency at the lowest footprint for AI workloads on microcontroller-class hardware. The TinyML-CAM pipeline, developed by a team of machine learning researchers in Europe, demonstrates what’s possible to achieve on relatively low-end hardware with a camera. Most specifically, they managed to reach over 80 FPS image recognition on the sub-$10 ESP32-CAM board with the open-source TinyML-CAM pipeline taking just about 1KB of RAM. It should work on other MCU boards with a camera, and training does not seem complex since we are told it takes around 30 minutes to implement a customized task. The researchers note that solutions like TensorFlow Lite for Microcontrollers and Edge Impulse already enable the execution of ML workloads, onMCU boards, using Neural Networks (NNs). However, those usually take quite a lot of memory, between 50 and 500 kB of RAM, and take 100 to 600 ms […]

Making a weather station with Maker Pi Pico Mini board and SparkFun SerLCD display

Cytron’s Maker Pi Pico Mini comes with a Raspberry Pi Pico or Raspberry Pi Pico W microcontroller board. It has the same features as the larger Maker Pi Pico including a GPIO LED, WS2812B Neopixel RGB LED, a passive piezo buzzer, programmable push buttons, and a reset button. I would like to thank Cytron for sending the Maker Pi Pico Mini board fitted with a Raspberry Pi Pico W as well as a character RGB LCD and a 3.7V Lithium Polymer battery. In this tutorial, we will show how to make an Internet connected weather station with the Maker Pi Pico Mini board using Arduino code and the OpenWeather API. We’ve already covered the Maker Pi Pico Mini board, so we’ll have a closer look at the accessories SparkFun SerLCD character display The SparkFun SerLCD is a 16×2 character display with a Microchip ATmega328P microcontroller that handles commands sent from […]

Banana Pi BPI-M2 Ultra SBC is now offered with Allwinner A40i industrial-grade processor

The Allwinner A40i and A60i industrial-grade quad-core and hexa-core Cortex-A7 processors were first introduced in 2018 with support for the wide -40°C to +85°C industrial temperature range, but so far I had not noticed any hardware making use of either processor. But Banana Pi is now offering the Banana Pi BPI-M2 Ultra SBC, which they launched in 2016 with the Allwinner R40 quad-core Cortex-A7 SoC, with the pin-to-pin and software-compatible Allwinner A40i industrial-grade processor. Banana Pi BPI-M2 Ultra specifications: SoC – Allwinner A40i quad-core Arm Cortex-A7 processor with Arm Mali-400MP2 GPU @ 500 MHz, 1080p60 H.264, MPEG-4, MPEG-1/2 video decoder, H.264 1080p45 video encoder System Memory – 2GB DDR3 SDRAM Storage – 8GB eMMC flash, SATA interface, microSD card slot Video Output HDMI 1.4 port up to 1080p60 4-lane MIPI DSI display connector, or RGB, or LVDS Audio I/O – 3.5mm headphone jack, digital audio output via HDMI, built-in microphone […]

HiPo batteryless NFC-powered 3.52-inch e-Paper display also comes with an SPI interface (Crowdfunding)

HiPo is a 3.52-inch black and white e-Paper Display that can be updated through NFC without the need for external power and offers an alternative to the 4.2-inch and 7.5-inch NFC-powered e-Paper displays from Wareshare that also operate without battery only using the data and power from NFC to update the image. Alternatively, Guangdong SID Technology’s HiPo display can also be connected to an SPI adapter board allowing the users to connect it to an STM32 board provided by the company, but it could also be used with Arduino boards, ESP8266 & ESP32 hardware platforms, Raspberry Pi SBCs and MCU boards, or any platform with an SPI interface. HiPo specifications: Controller – Ultrachip UC8251 all-in-one driver IC with timing controller for E-tag applications Display 3.52-inch B&W e-Paper display with 360 x 240 resolution (model name: SE0352N01-MNG-A0) 3 seconds refresh time On-chip display RAM White reflectance above 30% Contrast ratio above […]

Geniatech XPI-3566 is a business-card sized Rockchip R3566 SBC

Geniatech has added a new member to its XPI SBC family with the business card-sized XPI-3566 board powered by a Rockchip RK3566 quad-core Cortex-A55 processor, and mostly following the Raspberry Pi 3 form factor like its predecessors. The single board computer comes with 1GB to 8GB RAM, up to 64GB eMMC flash, HDMI 2.0 video output, Gigabit Ethernet, dual-band WiFi, a few USB ports, and a 40-pin GPIO header. It is said to target retail, “interactive communication”, and education applications. Geniatech XPI-3566 specifications: SoC – Rockchip RK3566 quad-core Cortex-A55 processor @ up to 1.8 GHz with Arm Mali-G52 2EE GPU, 0.8 TOPS AI accelerator System Memory – 2GB DDR (1GB, 4GB, or 8GB optional） Storage 16GB eMMC flash (8GB, 32GB, 64GB optional） MicroSD card socket Video Output HDMI 2.0 up to 4Kp60 MIPI DSI connector (not listed in the specs, but it can clearly be seen on the board) Camera […]

Pixel Pump is an open-source, manual pick-and-place machine (Crowdfunding)

Pixel Pump is an open-source hardware vacuum pump that should be easier to use than a pair of tweezers to pick and place SMT components, and suitable for prototypes and small production runs. The system comes with a pen with five exchangeable stainless-steel nozzles to match the size of components, a foot pedal, and several tactile silicone buttons with RGB backlighting to control the unit. The button on the unit (customized parts bought from Alibaba) allows you to change operation modes, switch between high- and low-power settings, or activate reverse mode to clean your nozzle. It’s also possible to configure vacuum power and LED brightness with the buttons. The foot pedal is used to control the vacuum pump to pick up and release the components. A serviceable air filter is also integrated into the design to protect the vacuum pump and valves from debris. Robin Reiter, Pixel Pump’s designer, explains […]
