Indoor air quality monitoring with Raspberry Pi and digital art #ArtTuesday #RaspberryPi @hacksterio @raspberry_pi

Maureen Rakotondraibe posts on hackster.io an Indoor Air Quality monitoring system via soothing digital art to control air quality aesthetically without over-stressing about it.

Indoor Air quality (IAQ) depends on numerous factors which includes temperature, humidity, particulates, and volatile organic compounds. Those factors and their consequences can be pretty scary, but my idea is to enable people to monitor their indoor air quality with as less stress as possible.

That’s why I chose sinusoidal curves to represent each factor. The higher the frequency means the higher the value compared to a reference curve. If the value is on the low side, the frequency will be lower than the reference curve.

As an embedded software engineer, I wanted to experiment with interfacing digital art, sensors and cloud visualization.

The system uses a Raspberry Pi 3B+, a SEN54 sensor and a display programmed in Processing. It uploads data to the cloud (IoT) via ThingSpeak.

Desk of Ladyada – TCRT1000 Stemma & Pico Plate Playground #DeskOfLadyada #Adafruit @Adafruit

OK, we got a whole bunch of the prototypes we’ve been working on last few weeks put together. Let’s check them out!

First up the TCRT1000 STEMMA board, which works great but needs a slight tweak to the emitter LED choke resistor.

Next we got 3 different Pico protoplates: a terminal block carrier, and two ‘underplates’. We set up a demo to verify connectivity and had one weird CAD bug that meant we accidentally had a missing ground wire.

We also got our SHT45 trinkey in, and we’re playing with some floppy drives we got that are missing an Index pulse and we’re still investigating.

Also on The Great Search this week: High Accuracy Temperature & Humidity Sensor

Catch Desk of Ladyada live on YouTube every week Sunday evenings and past episodes on YouTube.

HackSpace Magazine Issue 75 – Make Your Own Game Controller #RaspberryPiPico #CircuitPython @HackSpaceMag @Raspberry_Pi

HackSpace Magazine Issue 75 – DIY Gadgets features Alpakka, a 3D-print your own game controller.

Making a games controller is easy – you just need a handful of buttons, a Raspberry Pi Pico, and about 20 lines of CircuitPython.

The design files are open-source, so you can start completely from scratch if you like, but we took the easier option of buying the base PCB that comes with one side of surface-mount components already soldered on. We also got the additional components directly from Input Labs to make sure we got the correct parts.

With everything soldered into place, the next step is 3D printing the physical parts.

HackSpace Magazine Issue 75: DIY Gadgets @HackSpaceMag @Raspberry_Pi

HackSpace Magazine Issue 75 – DIY Gadgets

The trouble with capitalism is that you can only buy what someone else wants to sell you: if you want something truly unique you need to build it yourself. Luckily for us – and the makers we’ve rounded up for this wonderful collection of gadgets – that’s the fun part!

• Liven up any room with a Raspberry Pi and e-ink screen calculating the infinite beauty of the Mandelbrot set
• Go beyond the constraints of your 3D printer slicer with Full Control
• Develop old-fashioned photographic paper with coffee
• Use isopropyl alcohol and polyvinyl butyral to smooth away layer lines for glassy-smooth 3D prints

Amazing Retro Gaming Cabinet @Raspberry_Pi #PiDay #RaspberryPi

On the offhand chance you’d like a low-key gaming cabinet, here’s a great DIY project. Wikydtron has designed a wonderful gaming cabinet that would be the talk of any gaming party. Here’s more from instructables:

In a tribute to classic gaming & computer science student, I created a custom arcade cabinet that blends nostalgic fun with modern technology. This project was born from my passion for retro games and my love of woodworking and electronics. Featuring a Raspberry Pi 400 at its heart, a 22” display for crisp visuals, and a dismantled speaker system for rich sound, the cabinet also boasts vibrant LED-lit controls and a marquee that sets the mood for gaming sessions. The design is my personal touch, complete with custom decals that celebrate iconic game franchises. The bottom part of the cabinet, constructed from 2x4s and plywood, demonstrates that functionality meets creativity, offering stability and style. This arcade cabinet is more than a gaming machine; it’s a statement piece that lights up the room and brings joy to players of all ages.

See project!
