Serial Peripheral Interface Flash File System, or SPIFFS for short. It’s a light-weight file system for microcontrollers with an SPI flash chip. The on-board flash chip of the ESP8266 has plenty of space for your files.

Mes préférés étaient Twitter, Flickr et LinkedIn. J’ai été une utilisatrice plutôt précoce. Puis sont arrivés Facebook et Instagram, qui sont ensuite devenus les principales raisons pour lesquelles j’ai fermé la plupart de mes comptes.

How a Refrigeration cycle works

Most levitation occurs through magnets, but what about making objects levitate with something else, like sound? This design demonstrates acoustic levitation, a concept that uses opposing sound waves to make a tiny object levitate.

A tidy, versatile and feature-packed LORA QWERTY communication device mainly based on a Blackberry Q10 keyboard, nRF52840, SX1262 and a 2.7'' Sharp Memory LCD (LS027B7DH01).

Since I learned about LoRa I was curious about getting a communicator. I always liked walkie-talkies, and given that I go camping a few times a year, having the ability to communicate in remote areas with people nearby would be handy. With that as my motivation I started to explore the ways to leverage LoRa devices to put together a communicator tool.

Did you know you can update your outdated tile floor without removing the tile?! I updated our old, brown, dingy and dated tile floor with a floor paint coating system.

In our new house we had a huge empty wall, so I decided to build a shelf with an industrial and vintage style. I think the piece of furniture gives the room the personality we want and is much cheaper and fun to build!

In this particular case it means that all the optimizations and increases in efficiency do not go towards making a website which is faster at delivering even more megabytes. Rather it is a website which uses all the advances in technological efficiency, combined with specific hardware and software choices, to radically and drastically cut resource usage.

Over the past six months, I’ve become increasingly interested in the topic of web sustainability. The carbon footprint of the Internet was not something I used to give much thought to, which is surprising considering my interest in environmental issues and the fact that my profession is web-based.

A tiny WordPress theme focused on being as sustainable as possible.

Earlier this year we’ve been asked to help redesign the website of lowtechmagazine.com. The primary goal of the redesign was to radically reduce the energy use associated with accessing their web content. At the same time it is an attempt to find out what a low-tech website could be.

oilà plusieurs années que je questionne l’environnement numérique en tant qu’espace intangible mais qui pourtant possède des répercutions sur le vivant, sur la planète, sur la biodiversité… sur des espaces tangibles. Nombreux sont les articles qui disent que le numérique, Internet et le web émettent des gaz à effets de serre et donc que toute cette immatérialité (apparente) contribue à détruire notre environnement. Vous en avez sûrement déjà lu. Je ne reviendrai pas sur le sujet.

[Advanced Tinkering] over on YouTube has some pretty unique content, on subjects of chemistry and physics that are a little more, interesting let’s say — anyone fancy distilling cesium? The subject of this build is the visualization of ionizing radiation tracks, with one of our old favorite physics demonstrators, the venerable cloud chamber. The build video (embedded below,) shows the basic construction and performance of a Peltier effect cooler setup. The system is used to create a layer of supersaturated (and cold) alcohol vapor in which the radiation source or other experiment can be immersed.

A spectrum analyzer is a measurement tool that displays real-time frequency analysis of incoming audio signals.
