What we have actually built
Not proposal slides: these are live products, with an address, real users and ongoing maintenance. They all started from the same question — what can technology give back to people?
4 products live
in operation, not prototypes
From zero to domain
research, product, code and infrastructure under one roof
Thousands of songs
created by everyday people on Criar Músicas
Applied AI
generative models where they genuinely make a difference
Criar Músicas
Create a unique song to move someone you love
Criar Músicas takes a story told in someone's own words — a wedding, a longing, a thank-you that never fit inside a card — and returns a full song, lyrics and melody. You do not need to know anything about music: you need something to say.
- The story comes first You pick the theme, say who it is for and tell what happened. The lyrics grow from that, not from a template.
- Lyrics and melody together The song arrives complete, in the chosen style, ready to play, download and share.
- Easy to start Free account, song credits, and payments processed by Pagar.me and Stripe.
-
Choose the theme
Birthday, declaration, tribute — the mood of the song starts here.
-
Enter a name
Who is it for? The name goes into the lyrics and the song becomes theirs.
-
Record your story
The moments, the habits, the nickname. The more truth, the better the song.
-
Receive your song
Within minutes the finished track arrives, ready to play, download and send.
Jopoia
The community schedule, in the hands of the people who run it
Jopoia comes from the Guarani jo-poí, "open hands": giving and receiving in the same circle. The system brings together everything a community offers — trails, workshops, meals, lodging — into a single schedule that works on a phone and does not feel like office software. The community itself decides the calendar, the price and how many visitors it takes.
- Fits in a phone Big buttons, big type, one thing per screen. Usable with muddy hands.
- Every community on its own A community's schedule belongs to it. No outsider touches what is not theirs.
- No fine print No exclusivity contracts, no hidden commission. The deal stays plain.
-
Register the people
Whoever cooks, whoever runs the boat, whoever teaches basketry. Each person is entered once, with name and WhatsApp.
-
Register what the community offers
Trail, workshop, lunch, lodging — with duration, price and the person in charge.
-
Put it on the schedule
Day, time and number of spots. Done: the whole community sees the same week.
Weather Station
A weather station that fits the budget of whoever needs it
Weather Station measures temperature, humidity and pressure right where the data matters and publishes everything in real time, with a historical series. It is low-cost hardware, with an open design and open code, made for whoever has no budget for a commercial station: a school, a community, a farmer, field research. The first unit is live at carlota.iapuru.com.br, and the next goal is to have its readings certified by scientific climate bodies.
- Low cost, off-the-shelf parts A BME280 sensor and common components: it can be assembled, maintained and repaired without depending on a single supplier.
- Open end to end The hardware design and the dashboard code are open — anyone who wants to replicate the station does not have to ask permission.
- Real time, with history Temperature, humidity and pressure updated continuously, with 24 h, 48 h and 5-day series on the dashboard.
-
Assemble the station
Board, sensor and power. The bill of materials is public and the build needs no laboratory.
-
Register the device
Once configured, it starts sending readings on its own, with nobody writing anything down by hand.
-
Follow and compare
The dashboard shows the present and the history. Every new station joins the same base.
Robotizando
Workbench knowledge, open to whoever wants to build their own
Robotizando publishes articles, series and mini-courses on electronics, 3D printing, the internet of things and the free culture of hardware and software. It is where workbench practice turns into open material: the Impressão 3D Livre series builds a printer from scratch, one article per stage; the electronics and Arduino mini-courses start from the very beginning; and the site's calculators settle the tedious maths on the spot. Live since 2015, with no sign-up and no paywall.
- A series, not a one-off post Impressão 3D Livre follows the assembly of a printer from scratch, one article per stage — including what went wrong along the way.
- Open mini-courses Electronics for beginners and Arduino from scratch, in the order you actually learn them, with no sign-up and no paywall.
- Tools that settle the maths An LM317 calculator, voltage divider, LED resistor and the 3D printer figures, ready to use at the bench.
-
Pick a track
3D printing, electronics, internet of things or the vertical urban garden: each one is a self-contained sequence of articles.
-
Build along
The text assumes you have the part in your hand: bill of materials, schematic and the next step.
-
Adapt it to your case
Everything is free — copying, changing and republishing is the point. That is why it is out there.
Technology that gives something back
A song made from someone's story, a schedule kept by the people who welcome the visitor, a weather station anyone can assemble and a site that teaches you to build all of it may look unrelated. They are the same bet: collect the data at the source and use AI and software to widen what people already know how to do, instead of replacing them. That criterion decides what IA.PURU builds.
