📰 How NASA's Oxygen-Making Machine Could Change Mars Forever
Whether for breathing or sending rockets back home, we'll need to make oxygen on Mars. Soon, we'll know if it's possible.
According to NASA’s estimates, a four-person crew will need a lot of propellant—approximately 15,000 pounds of fuel and roughly 55,000 pounds of oxygen—to generate the thrust needed to leave the Martian surface and return home. Lugging all of that oxygen from Earth is a hassle.
That’s where the Mars Oxygen In-Situ Resource Utilization Experiment, or MOXIE, comes in.
Roughly the size of a car battery, MOXIE is one of NASA's many in-situ resource utilization (ISRU) experiments and the first to travel to space. In essence, ISRU is the agency’s version of homesteading, and the experiments explore ways for future spacefarers to produce things from resources available on other worlds.

📷 Discord Security Camera With an ESP32
Use an ESP32 Cam and a passive infrared (PIR) sensor to create a motion-activated security camera that will post a photo to a Discord channel, where you have access to create a webhook.
We'll build out the test circuit, using a breadboard and jump wire. We'll then build a wiring harness using Dupont connectors to allow for easy connections to the development board and PIR sensor.
We'll then use our choice of a wall or ceiling-mounted 3D printed case to contain our parts and our camera.
The ceiling-mounted camera makes use of an inexpensive decoy camera that can be purchased online.

📲 Over-the-Air Updates with AWS and FreeRTOS
What you should know about over-the-air communications using AWS and FreeRTOS
Updating firmware in the field has always been a critical component of even the earliest of embedded systems.
Access to hardware interfacing tools like a JTAG or SWD programmer provides physical access to embedded system programming ports. Other access methods for firmware updates include interfaces such as USB, automotive CAN, a serial port, and so on. Wireless port connectivity has gained prominence as more embedded devices become part of the IoT.
In today’s post, we will explore such wireless, over-the-air (OTA) communications using Amazon Web Services (AWS) and FreeRTOS.

🔧 PCB routing in Python
Preferring to spend hours typing code instead of graphically pushing traces around in a PCB layout tool, [James Bowman] over at ExCamera Labs has developed CuFlow, a method for routing PCBs in Python.
Whether or not you’re on-board with the concept, you have to admit the results look pretty good.

📰 The Scientific Instruments of the Mars Perseverance Rover
Perseverance is equipped with seven scientific instruments that are specially engineered state-of-the-art sensor modules designed for use on Mars with the goal of testing, sampling and analyzing the geology and atmosphere of the planet and any potential biological signatures.
▫️ Mastcam-Z - is a mast-mounted camera system tasked with the job of taking panoramic and stereoscopic photographs of the surface of Mars.
▫️ MEDA is a meteorological system created to take measurements of the Martian weather, atmospheric pressure, temperature and humidity but also the wind speed and direction.
▫️ PIXL is the rover’s Planetary Instrument for X-ray Lithochemistry. It’s a module that houses an x-ray spectrometer that can identify chemical elements at a very small scale.
▫️ RIMFAX - the Radar Imager for Mars’ Subsurface Experiment - is the first radar wave tool sent to the surface of Mars on a NASA mission.

💻 Crystal Language That Aims at C Performance with Ruby Syntax Releases 1.0
Crystal, a new object-oriented, compiled systems programming language that aims to blend the conciseness and friendliness of Ruby with the efficiency of C, recently released its first major version.
Crystal 1.0 has a syntax close to Ruby’s and features statically inferred types, C bindings, and macros. Crystal may attract developers with a Ruby/Rails, Elixir/Phoenix background.
The Crystal team explained the rationale behind the new language as follows:
▫️ We love Ruby’s efficiency for writing code.
▫️ We love C’s efficiency for running code.
▫️ We want the best of both worlds.
▫️ We want the compiler to understand what we mean without having to specify types everywhere.
▫️ We want full OOP.
▫️ Oh, and we don’t want to write C code to make the code run faster.

🖐🏻 Finger Bend sensor made of piezoresistive fabric
Finger Bend is a sensor created to find a way of making finger bends inside of a glove, control light and sound.
The construction of the sensor is simple, using piezoresistive fabric which changes its resistance when deformed. By sewing this into a sheath that can be placed on the finger, and wiring it up with conductive threads, it can be used to detect the flexion of the wearer’s digits by sampling the resistance with an analog to digital converter on any garden variety microcontroller.
The idea behind this glove is to then connect it to a body suit with other eTextile sensors for Immersive Audiovisual Performances.
