Several months ago, I was determined to build the bandwidth monitor posted by Legufix here on Instructables (instructables.com/Bandwidth-Monitor). I ordered the Raspberry Pi Zero and gathered other materials, but I wondered if I could just use the 7″ Raspberry Pi touchscreen that I had left over from another project. It would require a few changes …
I have an old iPad which has been dropped so many times that a piece of wire fell out the side, and I think that wire was the WiFi antenna. The iPad can only connect to WiFi when it’s close to the access point or when the signal is very strong. I figured out that …
Problem Statement Senior Design teams at Iowa State store their projects in the Senior Design lab in lockers secured by padlocks. These locks are reused semester after semester and previous students may remember their locker combination for the sake of tampering with current student’s projects. Additionally, administrators have the maintenance overhead of manually assigning lockers …
Objective Our goal was to solve the simultaneous localization and mapping (SLAM) problem by using WiFi measurements. Specifically we wanted to implement this paper, where they solved SLAM through a Graph SLAM formulation with WiFi signal strength and movement data from an IMU. Due to the constraints of graph SLAM, data would first be collected, and then …
I. Introduction Even the basic features of consumer devices often require an internet connection as mobileoperating systems shift to cloud-hosted platforms for services like photo storage, messaging,video playback, etc. While the expansion of mobile data networks has helped to provide “alwayson” connections for these devices, users are consuming more and more data at an unanticipatedrate. …
Introduction For pet owners, monitoring their food intake is one of the most important aspects of ensuring ahealthy and happy pet. Overeating has the potential of negatively affecting a pet’s life, while apet refusing to eat could be a sign of something more serious that may require a visit to the vet.Unfortunately, not all pet …
The easiest way to get your Raspberry Pi connected to the Internet at the University of Virginia is to use an Ethernet cable. If you want to use wireless, pretty much the only option is to use the hidden “wahoo” network. This is a quick tutorial for getting your Raspberry Pi to connect to the …
The daemon hostapd is a Linux service which enables a “host” computer to become a WiFi Access Point (AP). Thus “host” + “AP” + “d” (for daemon) gives the name hostapd. I originally learned to set up hostapd from instructions on Pastebin written by user Dryfire117,1 andlater found useful instructions on the Raspberry Pi website.2 The process originally involved …
Overview The Raspberry Pi 3B+ (and all other current Raspberry Pis) has built in WiFi. The “wlan0” interface is typically the default gateway of connection besides Ethernet, but it is not capable of entering “monitoring mode”. In this tutorial, we will show you how to ensure a separate network adapter is capable of monitoring mode …

Analyze sounds using AI on the edge and fleet intelligence. Can we use AI to help us identify and quantify noise pollution? In this project, we’re using a Coral Dev Board or a Raspberry Pi 4 with an attached Edge TPU to listen to ambient sounds 24/7 and categorize them for us. We’ll also demonstrate …
