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.

Core	ESP32-C6, 4 MB + 16/32 MB ext. flash
Control	Rotary encoder with button, buzzer
Modes	Dimmer · Shutter · Safe
Supply	AC and DC (dual power)
Interfaces	Wi-Fi, HTTP API, MQTT, web GUI, OTA
Status	Firmware 0.0.11, board 2607_SD v0.9.1

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.

Core	ESP32-C6, 16 MB ext. flash, two OTA slots
Trigger	Button on device, virtual button, HTTP reset API
Outputs	SMTP (STARTTLS/SSL), Telegram, webhook, MQTT, relay
Recipients	up to 10 groups
Time	SNTP, vacation mode, staged pre-warnings
Status	Web-GUI hardware active, CLI rebuild paused

RM-03Hardware2026-10 · FW 0.3.5In progress

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.

Core	ESP32-C6 on SmartKraft sk_core
Orientation	LIS3DSH accelerometer, face detection
Output	Display, vibration
Power	Battery with charge monitoring, sleep modes
Connectivity	USB CLI, BLE, Wi-Fi, optional webhook
Enclosure	3D print (BF.3mf), BF board in KiCad

RM-04Hardware2026-10 · PCB orderedIn progress

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.

Chip	ATtiny412, 8-pin
Touch	2 electrodes, MPSA13 Darlington, 100 kΩ / 10 MΩ
Sound	Piezo in anti-phase or coil buzzer via NPN
Songs	3 per firmware (e.g. Happy Birthday, Bella Ciao)
Programming	UPDI, own ESP32-C6 flasher without a PC
Status	Gerber done, board ordered at PCBWay

ChessRun: an endless runner on a scrolling chessboard

A board that scrolls one row down every turn. You move with chess moves, capture a piece and become it: from knight to rook, but also from queen to pawn. The goal is the opposing king. In the mirror mode King's Escape you are the king and last as long as you can. Every day everyone plays the same board.

Tech	TypeScript, Vite, own engine
Modes	ChessRun ♞ · King's Escape ♚
Board	8 rows visible, 4 to 8 columns selectable
Points	Pawn 1 · Knight 3 · Bishop 3 · Rook 5 · Queen 9 · King 25 (+1 life)
Backend	Cloudflare Worker + D1, weekly leaderboard
Status	Online, no ads and no tracking

Panther Launcher: a quiet Android home screen

A personal fork of the open-source mLauncher. Text lists instead of icon grids, categories in the app drawer, freely scalable widgets, own themes. Built as a signed APK for own use; whatever is generally useful goes back to the main project as a proposal.

Base	mLauncher (fork)
Language	Kotlin, Gradle KTS
Licence	GPL-3.0
Features	Text list, categories, widget sizes, themes
Distribution	Self-built APK, no store
Status	1.12.2.3, in daily use
