It is the first open source system to achieve 70+ mAP (75 mAP) on the COCO dataset and 80+ mAP (82.1 mAP) on the MPII dataset. To match poses corresponding to the same person in frames, an efficient online pose tracker called Pose Flow is also provided. It is the first open source online pose tracker to achieve 60+ mAP (66.5 mAP) and 50+ MOTA (58.3 MOTA) on the PoseTrack Challenge dataset. AlphaPose supports Linux and Windows.
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.
Design of dual-tone doorbell circuit based on 555 timer
The project uses RSL10 to build a sugar glider health monitoring system. With good exercise and diet, my little jelly (sugar glider) can grow up healthily.
Based on STM8S003K3 microcontroller, it has alarm and chime functions and automatic light sensing function.
The MicroByte is a tiny console capable of running games from the NES, GameBoy, GameBoy Color, Game Gear and Sega Master systems, with all components designed into this 78 x 17 x 40 mm package.
Since my four-wheel drive robot is powered by a 16.5V lithium battery, and there is no charger for this battery on the market, I am very confused about charging it. In desperation, we designed a portable and simple lithium battery charger. Solve the trouble of charging. The charger can output an adjustable charging current of 100mA-1A. The input voltage is VIN>18V, and it can be charged with the 19V voltage on the laptop. Charging time is generally determined according to the size of the charging output current.
Satellite GPS path recorder based on STM32 (complete source code attached).
Function description: 1. After power on, the LED light lights up, which means that the current light is in automatic control mode; 2. You can switch back and forth between automatic and manual modes through button K5; 3. In manual mode, buttons K2, K3, and K4 correspond to A light brightness; (unavailable when k1 is pressed) 4. In automatic mode, it must first detect someone before automatically controlling the brightness, otherwise the desk lamp will go out. You can block the light of the photoresistor, or use a flashlight to illuminate the photoresistor to simulate changes in lighting, so that you can see that the brightness of the desk lamp will change as the light intensity in the environment changes. The effect is that the weaker the light, the brighter the desk lamp. . If the human body sensor cannot detect anyone for 1 minute, the desk lamp will automatically turn off. (The photoresistor is behind the USB lamp); 5. Whether it is automatic mode or manual mode, the brightness is divided into 10 levels, and 0-9 is displayed on the LCD; 6. Set date and time: Press K1 (setting ) key, the cursor will flash at the displayed year position, indicating that the year can be adjusted at this time. If you need to adjust the year, press K3 (plus) and K4 (minus) to adjust the year. Then press the K2 (move) key, and the cursor will flash when the month position is displayed. The month can be adjusted in the same way. Press the K2 key again to set the day, hour, minute, and second respectively. 7. When approaching the ultrasonic wave, the buzzer will alarm.
Freedom KL26Z is an ultra-low-cost development platform for Kinetis L-series KL16 and KL26 MCUs based on Arm ® Cortex ® -M0+ processors.
Let’s see how to easily hack a remote control using ESP8266.
If you are away from home for a long time on a business trip, the goldfish at home will starve. Therefore, in order to prevent goldfish from starving when the owner is not at home, an automatic feeding robot was designed based on a 4-degree-of-freedom robotic arm and GD32E231. GD32E231 controls the robotic arm by generating PWM. At the same time, it picks up fish food from a fixed place and puts it into the fish tank according to the preset time. Through multiple manual trainings, the robotic arm automatically calculates the feeding based on the manual training data. eating position. At the same time, you can also add some auxiliary functions. You can roughly obtain the internal temperature of GD32E231 and the lighting conditions around the fish tank through the serial port or onboard ADC and photoresistor. You can turn on lighting equipment such as desk lamps when it is dark.
Password locks are relatively common in life. There are various types of locks. The most common ones are in the form of numbers. Generally, you need to enter a few numbers to complete the password. This project uses color to complete the password lock. There are many types of colors, which are more complicated than numbers. Using color cards to set the password and unlock the lock is more difficult to crack, and it is relatively safer.
The Renesas Pet Activity Monitor is a practical reference design created in celebration of the Year of the Dog. This device can track your dog’s barking and activity, and data can be viewed and downloaded from your PC.
The 1/8 brick power module in this reference design is designed based on the 1/8 brick power supply standard defined by the Distributed Power Open Standards Alliance (DOSA). This power module uses an Analog Devices ADP1051 to control the energy conversion from input to output.
mini-violin is an open source project for violin design, and the circuit schematic is quite simple. The ATtiny85 controls two LEDs and a piezo buzzer, in addition to a button to switch songs. What's particularly interesting is that the violin strings are connected to the analog inputs of the microcontroller so that they can be controlled by contacting conductive materials. Come play the violin.
