The device presented in the video represents marble maze game that is controlled using a smartphone via Bluetooth connection.
The device consists of two parts. The first is the Arduino part where the servo motors are controlled and the second part where the signals generated by the accelerometer are sent via the Android smartphone. It consist few components:
– Arduino Nano microcontroller
– Bluetooth adapter
– and two 9g servo motors
IOT PET FEEDER This project works based on IOT app. The app is connected to io.adafruit.com. When “FEED”button is pressed in the app, the data is sent to cloud. Food dispenser monitor the cloud, when it receives the “FEED”command then it opens the food in the tray.
In today’s video we look at how to extend the range of an existing WiFi network by repeating the signal. This extension will be done using an ESP32 NodeMCU. This process also works for ESP32 only.
ESP32 as WiFi NAT router. It can be used as — Simple range extender for an existing WiFi network — Setting up an additional WiFi network with different SSID/password for guests or IOT devices.

Measuring low resistances with a standard multimeter is difficult and very inaccurate. This device solves this problem and serves for accurate measurement of small resistances in the range of 0.1 ohm up to 50 ohms.
Jeri shows a bass guitar she build from an old C64. It uses the original sound chip (SID 6581) for keytar and string sounds.
Apple says they are aiming for zero climate impact by 2030. So to me that says a device should be able to be repaired when the time comes to, preventing it from becoming e-waste. But is that true?
Yay! Sega released a modern Game Gear. I hope it’s good!
Let’s explore the NEW Raspberry Pi 400 “Complete Computer Kit”! We’ll unbox, teardown, test RetroPie, the keyboard, & more! Could this be the ultimate retrocomputing emulator?
