📟 New development board ESP32-C3
ESP32-C3 attempts to address the most common needs for connected devices. Here are the key criteria that have been considered for the design of ESP32-C3:
▫️ Security is of prime importance. Even the lowest-cost connectivity solution needs to provide an appropriate level of security for common security threats.
▫️ Bluetooth Low Energy availability is useful for improving user experience and field diagnostics.
▫️ While cost is a very important parameter, the availability of sufficient memory for common use-cases is equally important.
ESP32-C3 is a single-core, 32-bit, RISC-V-based MCU with 400KB of SRAM, which is capable of running at 160MHz. It has integrated 2.4 GHz Wi-Fi and Bluetooth LE 5.0 with a long-range support. It has 22 programmable GPIOs with support for ADC, SPI, UART, I2C, I2S, RMT, TWAI, and PWM.

🎛 Machine Learning Based Gesture Detection Watch (ESP8266)
We’ll be taking the watch built in the previous instructable and plunge in some Machine Learning and see if we can detect what kind of gesture we are performing, and maybe in upcoming instructable we can use this gesture to perform some very cool projects based on this.
Final result:
Once the code is uploaded successfully make any gesture, the oled display should say what gesture you are performing. In my case the model worked 95% of the time, it just sometimes it suffers to find the right swipe gesture. Probably, the data I collected was noisy or maybe I wasn’t doing the motion right while collecting the data. Anyhow 95% is still good for me, we can do so much with this gesture detection!

🎛 Smart Video Doorbell: Intercom on Raspberry Pi
I came across some nice software to make a fast video / 2-way audio doorbell with a Raspberry Pi, and found a way to fit all the components in a small case. I will show you how to build it, including how to make push notifications work when you press the button.
