  • ESP8266 low-cost Wi-Fi full stack TCP/IP MCU (Arduino Compatible)

    ESP8266 is a tiny extremity cheap MCU with third-party library making it Arduino compatible. Features all the normal connections you would expect such as GPIO, SPI, I2C, I2C and UART to name a few, the biggest selling point is its size and build in WiFi support with full stack TCP / IP communications.

    Great for those IoT projects, connected devices and internet / network projects.

    Features

    • 32-bit RISC CPU: Tensilica Xtensa L106 running at 80 MHz*
    • 64 KiB of instruction RAM, 96 KiB of data RAM
    • External QSPI flash: 512 KiB to 4 MiB* (up to 16 MiB is supported)
    • IEEE 802.11 b/g/n Wi-Fi
      • Integrated TR switch, balun, LNA, power amplifier and matching network
      • WEP or WPA/WPA2 authentication, or open networks
    • 16 GPIO pins
    • SPI
    • I²C
    • I²S interfaces with DMA (sharing pins with GPIO)
    • UART on dedicated pins, plus a transmit-only UART can be enabled on GPIO2
    • 10-bit ADC (this is a Successive Approximation ADC)

  • DIY Deadlift servo winch test

    This was a test of a friend’s homemade servo winch to see how well it would coupe with a vertical deadweight lift, it did really well and lifted itself all the way up to the hook. Got a bit warm but no burning smells or fires, very impressed.

    This was a converted high torque steering servo, with the rope attached directly to the servo motor spindle and using a simple on / off / on switch to control the power to the DC motor for both in and out direction. Hope you enjoy the video.
