SynDimm: a wall dimmer that stays in sync with the smart home

A classic rotary dimmer on the wall and a smart home app know nothing about each other: turn the knob and the app shows the wrong state, switch from the app and the knob is wrong. SynDimm resolves the conflict with an ESP32-C6 behind the encoder: every turn is reported at once to Shelly, Philips Wiz or Home Assistant, and every change from there is mirrored on the device.

LebensSpur: a device that speaks when you no longer can

A dead man's switch for everyday life. You set a deadline and press the button regularly. If the press does not come, the device warns you first, then sends prepared messages and files to trusted people: by mail, Telegram, webhook or through a relay. For people living alone, care situations and anything someone must know if something happens to you.

BlockingFocus: a cube that blocks time

A countdown cube for focused work. Each face stands for a duration: turn the cube, face up, the timer runs. An accelerometer reads the orientation, a display shows the remaining time, a vibration motor marks the end. No screen, no app in the way, just an object on the desk that says: do not disturb now.

Muzzer: a melody card that plays on touch

A board the size of a card, three songs in the chip, no button. Touch pad B and the next note plays; touch C and the song changes, the card beeping as many times as the song number. An ATtiny412 sleeps almost without current between touches and wakes through two Darlington transistors that sense skin contact.

SoundPiezo in anti-phase or coil buzzer via NPN

House rules

Six sentences. Whoever does not stand behind them stays out.

§1

Anti-fascist. No room for authoritarian, nationalist or dehumanising positions.

§2

Anti-racist. Origin, skin colour, religion, residence status play no role.

§3

Anti-sexist. All genders as equals. Abuse leads to exclusion.

§4

Respect. Criticism of the work, not the person. Listening is part of it.

§5

Openness. What we build is documented and published.

§6

Reliability. Whoever takes a job reports back. Whoever gets stuck says so early.

And otherwise

No degree needed, but a field where you can show something: a board, a program, a repair, a piece of furniture.

Decisions are made by the collective, one vote per person. That holds today and becomes statute in the cooperative from seven people on.
