I considered going - now I have to. On a side note, TRU in Denmark has CyberMaster (...) (25 years ago, 22-Oct-00, to lugnet.robotics)

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 (...)

| | Re: Rechargable batteries
|
|
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 traced the circuitry of the tower the other day 'cos I wanted to build one of my own to work correctly with the spirit.icx. It is not a very complicated piece of electronics and I didn't find anything in there that wouldn't tolerate an external 9 (...) (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)
