I think the key is that the differential has a lot less resisitance than the white slip gear. Your idea would work, but if I understand you, the slip gear would be slipping the whole time the pump is pumping, meaning the motor has to overcome the (...) (25 years ago, 24-Oct-00, to lugnet.robotics)

Does this mechanism actually need the differential? If you used a 24 tooth crown (the horrible bendy one) on the motor and this turned the white slip gear for the switch and also a standard 24 tooth for the pump, the diff isn't needed, or is it just (...)

My first two sets ran very hot and did not last long. I replaced them recently with Ray-O-Vac "Rechargeables" (no longer called Renewals) and, using the very same model PS1 charger they work well. Perhaps they fixed something. I think the point is, (...) (25 years ago, 23-Oct-00, to lugnet.robotics)

I have also used the Ray-O-Vac Renewals in the RCX. Unfortunately, I have not had good luck with them. They seem to work fine in the RCX, but recharging them (in the Ray-O-Vac charger specially intended for the Renewals, model PS1) invariably causes (...) (25 years ago, 23-Oct-00, to lugnet.robotics)
