This clock uses side glow fiber optics to tell the time in a colorful way.

Forgot to bring out the recycling again? No more ... BinPal will remind you of your recycling duties, saves the planet and looks terrific on your fridge.

Have you played WORDLE yet? It’s a clever word game that’s basically Mastermind with 5-letter words.

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.

How a Refrigeration cycle works

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).

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.

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.

In this project, I focused on developing an AI-driven budget-friendly device to collect water quality data from various water resources in the field and forecast water pollution levels based on oxidation-reduction potential (ORP), pH, total dissolved solids (TDS), and turbidity measurements.

Commissioned by DesignSpark, which turned 10 in July 2020, I proposed the concept of Radioglobe to celebrate their landmark birthday. Devised in a 2x2m shed, during 2020 Covid Lockdown, on a shoestring budget, with only Zoom calls to communicate, RadioGlobe allows the user to explore thousands of the world’s radio stations by spinning a globe.

Aggregate, save and share links from all over the Web.

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.

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!

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

[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.

I'm Michael Lynch, software developer and blogger. I used to work as a software engineer at large companies, but now I run small software businesses of my own and blog about the process.

When I was growing up in the 90s, I remember wanting to get on the Internet. My parents weren’t going to help me, so I called up an ISP and said I wanted to set up an account. They asked for my name and I gave them a fake name. And then they asked for a credit card number and I told them I had to find my wallet and call them back.

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.

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.

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.

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.

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.
