    • Sunlight-luminosity measurement with a single board computer (raspberry-orangepi)  + (As you might not know, the meteorological As you might not know, the meteorological surface synoptic observations data (SYNOP, available here: https://donneespubliques.meteofrance.fr/?fond=produit&id_produit=90&id_rubrique=32) does not take into account sunlight/luminosity.

      Sunlight/luminosity data can be interesting to gather for a diversity of uses (home well-being, photovoltaics production, plants care,...).

      For photovoltaics, although the technology is old, I did not manage to find reliable measurements for cloudy weather.

      We find videos of such a measurement, for example this one:
      https://www.youtube.com/watch?v=H_Aow78MFmQ&ab_channel=TopeSosanya
      that may suggest that solar pannels produce at 50% of their nominal capacity.

      My measurement instruments being subject to interferences, I dont really trust my measurements to be reliable, so i thought about producing simple code that other users less subject to interferences could reuse at their convenience.

      This tutorial will allow you, with only two commands (after installing operating system and docker), to use your single board computer like a weather station recording sunlight/luminosity every minute in a database and producing a web page where results can be retrieved with date filters options.
      the demo is available here:
      https://vpn.matangi.dev/lum

      Note: dont trust the measurements displayed in the demo above: the ecoterrorist french police doctrine destroys the possibility to do science correctly in france with computers. I do not have the adequate financial and technical means, and I do not want to spend time playing cat and mouse again and again to dodge recurring cyber attacks and shackles. The logic integrity of the code is good. If the system changes, or if you are not targetted too much, this could be useful.

      Publishing on lowtechlab is a signal to encourage you to do your own measurements with diy stuff, like a multimeter and an old offline camera to upload on youtube or peertube. If you read this tutorial and you are not yet an ecoterrorist, you have a superpower: the invisibility cape.

      This tutorial is not really "lowtech" at first look because we talk about computers and photovoltaics

      However it is as didactic as possible and follows a lowtech philosophy to share knowledge, avoid unreachable tech by information rentention, complexification by design, or proprietary dependance by design.

      We also give sizign tools for photovoltaics with a few explanation. It's up to to you to size your computer working hours on a sun schedule, ie respecting human temporalities.

      Nextcloud (framasoft offers a service here: https://www.frama.space/abc/fr ) is a cool service to organise collectively and allows to share files, have a directory, a chat, work cooperatively on libreoffice files, and even do visios. We can also imagine mobile infokisosks on this principle.

      The tutorial puts into question the vpn market, the phtovoltaics with brand new and expensive batteries (in reality photovoltaics has become too competitive compared to petrleum and even more compared to nuclear power!), and the gafam market and their surveillance design is damaging trust and social links. The commands are those for a debian system

Um aquecedor-a-lenha (ou aquecedor-de-acumulação residencial, ou calefator caseiro) é um equipamento de aquecimento primário. Seu interior, composto por materiais pesados (pedra, tijolo ou concreto), armazena a energia que é produzida por uma combustão diária única e intensa (entre 1 e 3 horas), e permanece emitindo calor por um longo tempo após a extinção da chama (por até 24 horas). Seu aquecedor confere-lhe uma inércia térmica que permite atenuar a curva de temperatura no interior de um edifício (o que os fez serem chamados de "fornos de inércia"). Toda a quantidade de madeira necessária para aquecer o ambiente é queimada de uma só vez, o que induz a altas temperaturas dentro do aquecedor (calefator), e permite obter uma combustão completa e pouco poluente. Esse aquecedor foi concebido para absorver a maior parte da energia da combustão e da fumaça. Ao sair da estufa, a fumaça fica, portanto, consideravelmente resfriada. O calor acumulado é difundido principalmente por radiação e, em menor porcentagem, por convecção. O modo de aquecimento por radiação exige que o aquecedor seja colocado no centro do ambiente. A maioria dos aquecedores-a-lenha atuais são colocados na sala principal, aberta para a sala-de-estar, sala de jantar e cozinha. Com um rendimento majoritariamente superior a 80%, esses aquecedores (calefatores) estão entre os equipamentos movidos a lenha mais eficientes.

    • Semi-removable Mass Stove  + (Semi-removable inertia mass stove. A massSemi-removable inertia mass stove. A mass storage stove or ‘heat storage stove’ is a primary heating device. Its mass, which is made up of heavy material (stone, brick and concrete), stores energy from a fire that burns once during the day (lasting between 1 and 3 hours). Once the fire has gone out, it then continues to give out heat over a prolonged period (for up to 24 hours). Its mass provides thermal inertia which helps to keep an even temperature inside a building (which is why these stoves are often also called “inertia stoves”). The whole of the quantity of wood needed to heat the dwelling is burnt in one go, making it burn hotter which allows complete and more environmentally-friendly combustion. It is a storage device which is designed to absorb the bulk of the energy that is generated from combustion and exhaust gases, which cool down considerably once out of the stove. Accumulated heat is mainly diffused by radiation and, in a few cases, by convection. This particular type of heating, i.e. that uses radiation, is best located in the centre of the dwelling and therefore, most mass stoves these days are positioned in the main room which opens out onto the lounge, dining room and kitchen. As yield tends tend to be in the majority of cases higher than 80%, these stoves are considered to be one of the most efficient wood-fuelled heating devices.
