Electric Go Kart
- Cleaned up my study (junk away)
- Further worked on the 'bad' battery. Had to turn it off to leave for work. When I left, voltages were: 4.20, 4.20, 4.19, 4.18, 4.17
- Brakes turned up (hooray ! perfect !)
- 10K slide potentiometers turned up. Don't know if these are the right decision. They are quite "sticky" (ie they do not slide incredibly easily).
- Chased questions about balance connectors staying on during use - see http://www.rcgroups.com/forums/showthread.php?t=932319&page=24#post12751921
- Also PM'ed methods at endless sphere.
- Worked on accelerator.
- Asked boys (they prefer sliding to twisting).
- Got sliding one to slide more easily.
- Tested with controller and batteries. Discovered: (a) circuit diagram is wrong (max 8volts - fixed that), (b) sliding Pot is only effective for 1/2 of distance ... and (c) does not allow very accurate control of speed (movements of pot are too small to make sense when driving).
- Therefore - ordered twist grip controller from Oatley Electronics, designed specifically for this controller (is probably hall effect).
- Finished charging all batteries. Sorted out the "sucky" one.
