fast-stacker

DIY cheap, fast, portable, and accurate automated macro focus stacking rail (based on ESP8266 microcontroller - since v2.0) which can be used with a wide range of photo cameras, and magnifications from standard macro (1:1) to extreme macro (up to 60:1 - since v2.0). To reproduce this project, you need some basic mechanical and soldering skills.

macro-scripts

A set of BASH scripts and C++ programs representing a complete workflow for processing macro focus stacking photographs. Utilizes other open source packages (dcraw, Hugin, ImageMagick) internally. The Deadpixels script (automatic detection of dead and hot pixels in raw photographs) can be of use for general photography, not just for macro photography.

water_leak_sensor

Water leak sensor based on ESP8266, which will sound a local alarm (piezo buzzer, LED) if a water leak is detected. It will also send the alarm over WiFi/MQTT to your smart home server (like OpenHAB), and will make all other water sensors in the house sound an alarm.
