Plant Bot is an open source project based on ESP32 that allows a single PCB to perform the functions of detecting humidity, watering, providing lighting, and controlling and communicating with the user via WiFi/BLE.
Have you ever thought about attaching an inertial measurement unit (IMU) to an object to track its posture and motion? Tracer provides high-performance, safe, reliable and low-cost object tracking. Tracer can be easily attached to objects using Velcro. It can tilt and track rhythm as the bike's frame tilts, it can record the number of shots taken with a tennis racquet, and it can even differentiate between topspin and chip shots. Let your imagination run wild and explore more interesting applications of Tracer!
The WiFi remote control is based on ESP32 Pico D4 MCU and 160x80 pixel mini TFT display. Additionally, there are onboard I2C temperature and humidity sensors and an accelerometer.
Somu is a small FIDO2 security key that you can use with your Google, Twitter, and GitHub accounts for two-factor authentication, or with your Microsoft account for passwordless login.
Battery-operated fluorescent lighting projects often appeared in hobby electronic magazines in the 1980s. I always thought that fluorescent lamps were devices that only used AC power at that time. Those articles about using batteries to light miniature fluorescent lamps attracted me. I made some fluorescent lights, but I couldn't get good practical use out of them from a lamp efficiency and longevity perspective. That's because I was just reading the article and knew nothing about the theory of discharge lamps or even electronics. I don't know what to change to get good results, and I'm losing interest in it. However I found a battery powered fluorescent light project online that was identical to the schematic I was working on. So I "revived" the project after 30 years with modern driver circuits and correct theory.
Grapevines use a lot of water and the soil dries out quickly, so they need to be watered twice a day. This project is about using an unmanned watering system to water flower pots.
This Bilibili small TV uses esp32 as the main control, lvgl GUI interface design, and is developed based on idf4.0 to support smartconfig or WeChat airkiss distribution. Its functions include: network connection display, network acquisition time, weather display, temperature and humidity collection, Fan count display, mqtt temperature and humidity upload, etc. All software and hardware are open source.
This design is a plug-in from FLIR's Tau2 LWIR core. Both the LVDS and CMOS channels are connected to the UART configuration channel through the SYZYGY connector.
Plug-in for FLIR's boson LWIR kernel. The 24-bit CMOS channel is connected through the SYZYGY connector along with the UART configuration channel.
The EPC901 is a 1024x1 CCD sensor capable of providing 50MHz pixel output. It outputs analog voltage from the CCD element. The author paired it with a 50MSps ADC on a SYZYGY board. The datasheet says it can run up to 50k fps. External I/O is provided via optocouplers to facilitate connection to external trigger sources such as motion controllers. This board will assist in conducting experiments on the new PnP platform. Objects can be moved through the line scanner to capture the position of the photo.
SYZYGY is an FPGA extension standard for medium to high speed interfaces. This design is a breakout board for connecting dual Atto320 LWIR sensors. Designed to mate with existing sensor breakout boards that provide FFC connectivity.
SYZYGY is an FPGA extension standard for medium to high speed interfaces. This design breaks out all 32 I/O pins into taps with 0.1" headers. A small prototyping area is also provided.
The project is a small desktop-level robot tool that can be used to help you control your computer, etc. Its functions can be defined by you. The inspiration for the appearance design is EVE in WALL-E~ The robot has a USB communication display screen function, has 6 degrees of freedom (one roll and pitch for the hand, one for the neck, and one for the waist), and uses its own modified special servo to support the joints Angle return.
Arduino® Nicla Vision is a ready-to-use standalone camera for analyzing and processing images at the edge. It's suitable for asset tracking, object recognition and predictive maintenance thanks to its 2MP color camera, smart 6-axis motion sensor, integrated microphone and distance sensor. Quickly implement sensor nodes that send collected data to the Arduino® Cloud (or third-party vendor service) via integrated WiFi/BLE connectivity.
Ported the 3D rotation + meteor shower background demo to H7, and the pure rendering is very smooth.
This design is a PMOD with the ublox NEO GNSS receiver footprint. Able to receive GPS and GLONASS simultaneously.
icebreaker++ is a very nice and convenient little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.
This computing watch is designed using the SAML22 ARM microcontroller. This particular microcontroller has a segmented LCD controller capable of driving the LCD used inside the watch.
Mega-Cube is a light cube that drives 4096 LEDs based on PL9823. The main control is Teensy4.0 based on NXP i.MXRT1060 FlexIO function and many 595 shift registers. It can control up to 32 channels, each channel 1000 LED.
In the open source electromyography project shared here, the author used this product to create a computer game control effect.
