35mm C-41 Color Film Negative Orange Mask Remover & Inverter
Convert digitizer scans of color film negatives into true-to-life positive photographs. Automatically subtracts the chemical orange/amber polymer mask base without creating murky cyan casts.
Stereogram Magic Eye 3D Depth Map Image Generator
Create authentic 90s Single Image Random Dot Stereograms (SIRDS) and textured autostereograms. Converge or diverge your eyes on the two alignment dots to see the hidden 3D object pop out!
The Physical & Digital Chiptune & Hardware Pipeline
Creating physical cassette releases or programming microcontrollers (Arduino, ESP32, Game Boy DMG) requires specialized file layouts that modern software has abandoned.
Our OLED converter formats images into exact row-major horizontal or vertical page bytes ready for Adafruit_GFX and U8g2 libraries with PROGMEM flash memory optimization.
For cassette tape musicians, our J-Card generator provides exact millimetric origami fold lines, 90-degree spine typography, and tracklist panels calibrated for standard Norelco cases.
Frequently Asked Questions
What is the difference between Adafruit GFX and SSD1306 Page Mode byte formatting?▼
Adafruit GFX reads 8 horizontal pixels packed into each byte from left to right. SSD1306 hardware page mode reads 8 vertical pixels per byte in 8-pixel horizontal bands. Selecting the wrong format results in garbled diagonal stripes.
What paper should I use for printing cassette J-Cards?▼
We recommend 65lb to 80lb (176–216 gsm) smooth matte cardstock. It folds cleanly along the dashed crease lines and fits snugly inside standard Norelco plastic tape cases.
