This video shows an affordable way to add USB support to maker projects. $2 for 10 PCBs (Any Color): https://jlcpcb.com (sponsor) The CH559 is a 8051 architecture based microcontroller that has built in dual USB Hosts. This allows to interface generic Keyboards, Mice, MIDI devices and in my case gamepads. I added this chip as an add on to my ESP32 based game console to replace the SNES controllers by cheap generic ones. The communications is handled over UART which can be done by both ends in hardware. There still is some work to do but you can try it out already. Have fun!

A new speed controller improves my DIY electric scooter to support regenerative braking and battery protection. The VESC provides a ton of options to control the hub motor. A simple analog stick is used a throttle now. Enjoy!

In this video we upgrade a basic doorbell to send notifications over WiFi. With some power harvesting no battery is required. An optional Node-RED server translates the signal and activates a visual notification remotely. This not only helps if the bell isn't audible but can also be use for hearing disabled people.

This Ping Pong LED Wall is made of large PCBs sponsored by: PCBWay https://www.pcbway.com/?from=bitluni It consists of 1920 ping pong balls as pixels and is controlled by an ESP32. The parallel data lines allow over 74fps and a camera live feed. The panels are easy to exchange in case of failure and built in bus lines and configurable mounting plates allow to build a display of any shape. My Arduino library provides the LED driver and a graphics interface to draw and display anything.
