In another experiment I looked at making a developer from Paracetamol/Tylenol without using any sulfite.
Note, Sodium Hydroxide is hazardous, caustic:

Solution A:
I dissolved 20g sodium hydroxide in 250ml water, added 15g (contents of 30 capsules) Paracetamol whilst hot,with stirring.
After filtering through cotton wool the solution was left in a 250ml sealed bottle for 72 hrs.The paracetamol hydrolyses to p-aminophenolate which is a developing agent.

LS-1b Developer:
Solution A above...............................50ml
Ascorbic Acid....................................20g
Sodium Carbonate photo grade anh.....6.7g
Water to ..........................................1L
pH~9

HP5+ was developed in LS-1b 10m 20C, EI~250, see attachment showing 0.1 in square section of negative.
It's a mid-acutance rather than fine grain developer.

Later I may try washing soda crystals instead of sodium carbonate anh, the developer could then be made from Paracetamol,Caustic Soda pellets, Ascorbic Acid (Vitamin C from the health food shop) and washing soda crystals.
