Offline Speech Recognition on Raspberry Pi 4 with Respeaker

Faster than real-time! Based on Mozilla’s DeepSpeech Engine 0.9.* UPDATE June 2020: Revised instructions for DeepSpeech version 0.7.*, except Raspberry Pi 4 screenshots which remained unchanged. The benchmark table has remained the same, as I didn’t observe any improvement in inference speed. However, there appears to have been a precision enhancement – the audio file […]

Smart Gates

Identify Cars Using Raspberry Pi Description The principle of operation: The car drives up to the gates. Camera reads the car plate numbers. Checks the read number with the database; if it finds one, then it opens the gate and lets the car pass. Each car at the gates is photographed, then a photo is

Homebrew SWR and power meter

DIY SWR and Power Meter

To start, the SWR meter mentioned in this article isn’t completely homemade because I used the circuit from the Arduino Projects of Amateur Radio book as a reference. Even though I purchased the book and acknowledge the authors’ copyright, I will still share my diagram here. What is the reason? Initially, the design showcased in

14654 FLIR Radiometric Lepton Dev Kit 01

FLIR Lepton Hookup Guide

Introduction Note: This tutorial was originally written for the FLiR Lepton [KIT-13233]. However, the FLiR Lepton 2.5 with Radiometry should function the same. Upon discovering that we would be evaluating a Long Wave Infrared (LWIR) camera, our team repeatedly exclaimed two words: Predator Vision. Yes, we were finally going to see the unseen realm of heat,

High Resolution Thermal Camera with Raspberry Pi and MLX90640

High Resolution Thermal Camera with Raspberry Pi and MLX90640

Thermal cameras are very similar to standard cameras in that they record their images with light. The most significant distinction is that thermal cameras detect and filter light such that only the infrared region of the electromagnetic spectrum is recorded, not the visible region [read more about infrared cameras here and https:Available: [//thermalcameras. guide]. Infrared
