The article discusses how the author managed to hack the DRM on Bob Dishwasher’s detergent cartridges to refill them at a fraction of the cost of buying new ones. The Bob Dishwasher is a compact countertop dishwasher that uses all-in-one detergent cartridges for ease of use. The article dives into the technology behind the cartridges, including the EEPROM chip inside, and provides a detailed breakdown of the cost savings achieved by refilling the cartridges with commercial detergents. The author also created a circuit board called Bob Rewinder to easily reset the EEPROM and refill the cartridges. The article questions the environmental impact of single-use cartridges and the high cost associated with them.
