Like smart TVs, smart projectors also features built-in Wifi connectivity and support media streaming from services like Netflix, YouTube, Hulu, Amazon, and so on. A recent video from NovaSpirit (posted below) illustrates how to convert a cheap $70 standard projector into a smart projector by adding a Raspberry Pi Zero. An USB hub is hardwired to the Pi Zero so that you can use an Wifi dongle (for internet connectivity) and an USB keyboard. The Pi Zero board derives power from the projector circuit board.

Talking multimeter using PIC32 microcontroller

Posted on by Leave a comment

Rachel Dipirro and Jonathan Lo (students of Cornell) built a talking multimeter as their final project for the 2016 Fall ECE 4760 (“Designing with Microcontrollers”) course. Their talking multimeter is powered with the PIC32MX250F128B microcontroller, and it can speak the measured readings while operating as a volt-, ohm-, and capacitance-meter. It is aimed to provide the user these measurements without turning away from the circuit currently being worked on. The speaking measurement system will provides an auditory alternative to a visual meter. Our system consists of a TFT LCD to display the reading, a keypad to read user input about the mode
