 | | 9V batery box (6 AA) - pressed too much

|
At the last robot contest, I discovered that if I press down on either side of the battery box red switch, the power stops. It is hard to put into words. If you hook up a motor to this battery box: (URL) press the red button, the motor spins. if (...) (19 years ago, 6-Oct-05, to lugnet.technic)

(...) Thanks for your suggestions. I have a number of restrictions for this specific design... but have been wondering in general the best way. (So far I think Mark has the best suggestion using an offset cam). For this specific project I am (...) (19 years ago, 6-Oct-05, to lugnet.technic, FTX)

(...) Do the two beams need to be studded? Bracing two studless beams could be a lot easier, not as high either. If you can show us what you are trying to fit this into, I'm sure someone here will come up with the solution. :) Cheers, Chris. (19 years ago, 6-Oct-05, to lugnet.technic)

(...) That is a joy to watch. Even if it is slower than some other gait, it is very interesting to watch. I have vaguely followed your pneumatic threads, watching the cool diagrams and devices, but I will admit you lost me a while back with this. (...)

(...) How many studs of overlap can you have? Also, how much space can you have on the sides? A tacky way to solve the problem would be to run a string through the holes in a spiral type fasion and then tie the ends together. Hey; no one can say it (...)

(...) You could try a cam with an offset of 1 hole sideways along the beams - the distance between the offset holes is about 1.5L (12mm). Use the hole in the middle of the large end of the cam as well as the hole at the small end. You probably need (...) (19 years ago, 5-Oct-05, to lugnet.technic, FTX)

(...) Thanks for the ideas... however I am constrained to a height of 2 beams. This height restriction is what is causing me grief as I can not space the beams or add above/below to use the liftarms. Jeff (19 years ago, 5-Oct-05, to lugnet.technic, FTX)

(...) I tried fitting a 3mm flexible hose into a normal hose, but without success! It might be possible but would take longer than fitting a 3mm rigid flex tube into a normal hose. The 3mm hose breaks easily if it is stretched over a 3mm flex tube - (...) (19 years ago, 5-Oct-05, to lugnet.technic)

| | Usage of hose 3mm diameter.
|
|
I'm wondering if this hose can be safely used in pneumatic switching circuits or if it's thin inside diameter would restrict airflow somewhat. I've got an idea where I might be tight on space around the valves, so I wondered to myself if 3mm hose is (...) (19 years ago, 5-Oct-05, to lugnet.technic)
