DIY Raspberry Pi Pico Text-to-Speech Using Wit.ai Text-to-Speech, or TTS, is a technology that converts written text into spoken audio. It is widely used in voice assistants, accessibility tools, alert systems, kiosks, and smart devices. On computers and smartphones, TTS works smoothly because these systems have enough processing power and memory to handle speech generation locally. Microcontrollers are different.… |

A Smart Macro Pad with Haptic Feedback Ever thought of controlling your computer using buttons and a knob that actually feel different when you use them? Most input devices, like keyboards and mice, only give visual feedback on the screen and do not provide any physical sensation to indicate how an action feels. The Macropad changes this experience by adding the sense of touch to everyday computer controls. This is a six-button… |

Interfacing the RTC Module with Raspberry Pi Pico In this guide, we will create a simple and precise digital clock using the Raspberry Pi Pico RTC DS3231 Module through the Arduino IDE. We will use a 16x2 I²C LCD screen to display the information. Since the screen is small, we will write smart code that changes what is shown on the screen. For a few seconds, it will display the time and date, and then switch to show the temperature.… |

An RP2040-Powered Cyberdeck That Runs on MicroPython We have seen cyberdecks built around Raspberry Pi and other single-board computers, but this is the first time we’ve come across one powered by dual RP2040 chips. In a recent video, Abe from Abe’s Projects presents a compact cyberdeck using the Pimoroni PicoVision, a board that combines two RP2040 microcontrollers—one acting as a CPU and the other as a GPU—to drive an HDMI display. This setup… |
