This site is a collection of imaging experiments, instrument repairs, reverse engineering and practical electronics. Start with the projects below, then browse by topic for the complete archive.
Featured projects
Optics and photography
Schlieren on a Stick
A phone, a spherical mirror and a telescoping support make density changes in air visible in a compact portable setup.
Scientific imaging
Active Multispectral Imaging
More than 30 measured LED bands, a monochrome industrial camera and Raspberry Pi control inside a purpose built enclosure.
Sensor modification
Raspberry Pi Camera CFA Removal
A close look at physically removing the color filter array from an OV5647 image sensor and measuring the result.
Instrument interface
Microscope Measurement Overlay
A small LCD and optical combiner place an oscilloscope waveform inside the microscope view.
Accessible tools
Servo Controlled Multimeter
A simple mechanical interface for repetitive tests, hands free control and easier access to a meter selector.
Embedded camera control
Sony Block Camera and RC Control
An Arduino translates RC receiver pulses into Sony VISCA zoom commands.

Early UAV systems
These 2011 to 2013 projects show what field integration required before compact flight computers, radios and controllers became easy to buy.
How these articles are written
The articles explain the objective, the parts, the measured values and the important electrical, optical and mechanical limits. They leave room to choose parts and improve the design. That keeps the projects accessible without turning them into copy by numbers kits.
Check current data sheets and local rules before building. Use current limiting, fusing, eye protection and safe battery handling where the project calls for them. Medical imaging experiments on this site are educational prototypes. Radio work is limited to systems you own or have permission to test.
