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 […]

The Musical Instrument Digital Interface has a great acronym that is both nice to say and cleanly descriptive. The standard for talking to musical instruments relies on a serial signal at 31250 bps, which makes it easy to transmit using any old microcontroller UART with a settable baud rate. However, [Kevin] has dived into explore the

Staying through to their pace-setting tradition, the Raspberry Pi Foundation has once again pushed the bar of what is achievable with SBCs, higher, with the launch of what is arguably the most powerful camera ever shipped with an SBC. The first official Raspberry Pi camera with 5MP resolution which was launched back in May 2013, was followed
Problem Statement 1.1 Requirements and Specifications Due to the system being a completely new idea, specific requirements were not provided. It was decidedthat the following values should suffice for an efficient system. The group will strive to meet all of thefollowing quantified expectations:â—Ź Objective/Purpose: The main requirement is to effectively filter contaminants within a liquid.This

N.B. this is new and still being tested. The following Python samples demonstrate several single-channel filters for processing sensor data. The filter functions are purely numeric operations and should work on any Python or CircuitPython system. This supports offline testing, as they can be debugged and evaluated on a normal desktop computer. The code is

Introduction Problem Statement There are inherently a lot of problems with not knowing where people are located at. Whetherthey are in the location they say they are, or if they are missing and others are trying to find them.When workers cannot be located, there are safety concerns, for example if you are working withsomething dangerous
