| (...) So am I. However, I'm also into R/C aircraft so I have a long history with batteries and motors and could talk your ear off about them. I could also explain why the battery pack costs so much! (...) Yes, I give you permission to go home. You (...) (15 years ago, 3-Apr-09, to lugnet.trains, lugnet.technic, lugnet.robotics, FTX)
| | | | | Re: Help needed on gear spacing, and another question
|
| (...) Technic worm gears are not really made to mesh with the 1x4 racks. The problem is that the racks do not have any pitch (the gear teeth are perpendicular to the longitudinal axis of the rack). The worm gear, by definition, does have a pitch. In (...) (15 years ago, 3-Apr-09, to lugnet.technic, FTX)
| | | | | Help needed on gear spacing, and another question
|
| Hi all, I have two requests; any help would be appreciated. First question: what is the proper spacing to use when using a worm gear to drive a rack gear? I have (supposing studs up) a horizontal axle with a standard worm gear (4716) on the axle. I (...) (15 years ago, 3-Apr-09, to lugnet.technic)

| (...) Eric: Thanks for the awesome explanation! I learned new stuff today...does that mean I can go home now? :-) I'm excited to see how the new motor and battery box pull. I think the new PF trains could add a lot of functionality to existing 9V (...) (15 years ago, 3-Apr-09, to lugnet.trains, lugnet.technic, lugnet.robotics)
| | | | | Re: PF train motor

| (...) They made it 7.4V because all lithium polymer battery cells are 3.6 - 3.8V. Since this is a pack with 2 cells in series, you get 7.4V. A 3 cell pack is typically 11.2V. As you can see, keeping the old 9V system was not really an option if (...) (15 years ago, 3-Apr-09, to lugnet.trains, lugnet.technic, lugnet.robotics)

| (...) BTW, forgot to mention that the protocol indeed defines 7 PWM steps in each direction (forward/backward) plus the Float and Break states. (15 years ago, 30-Mar-09, to lugnet.technic, lugnet.robotics, FTX)

| (...) Hi Eric, Thanks for sharing with your findings about the new PF remote with us! I haven't played with it yet, so was very curious to know about some implementation details and you gave full light on those. From your description the remote (...)

Im not surprised the power level is not continuous, its a digital signal not analogue! iirc its 2 bytes of data, thats the mode and data for both channels in combo mode. (There (...)
