Basic Caffenol
8oz water
4tsp instant cofee
2tsp Na-Carbonate (WASHING SODA)

Tri-x takes about 20 minutes @20C

Caffenol LC (Low contrast for microfilm) by Donald Quails
8oz water
2tsp instant coffee
2tsp Na-Carbonate (WASSHING SODA)

Imagelink HQ and Copex Rapid, 25 to 30 minutes at around 70 F

Caffenol+C
Same as Caffenol but ading 4g/l of sodium ascorbate

Dev times are about the same, but stain is restrained and shadow detail is improved.

The drill for both Caffenol and Caffenol LC is to mix in the soda and
stir
until all cloudiness and grittiness are gone, then add the coffee and
stir
until grittiness is gone again and the solution appears uniform.
