|
Hi all. I want play with my RCX this Christmas so I have thought about building a proximity sensor. So guys, do you have any ideas?. I prefer simple and cheap solutions. Bye. (24 years ago, 19-Dec-01, to lugnet.robotics)

Hi, We need to send and receive messages between a PC and a RCX with legOs, but we can't find the serial communication procedures in the code or libraries. Does anybody can help us??? Thanks in advance, Mauro + Prof. Dr. Mauro Roisenberg Dept. de (...) (24 years ago, 19-Dec-01, to lugnet.robotics)

| | Re: Battery use
|
|
Yes, but it won't last long. The HB's electronics draw around 20 - 40 mA. the lifetime of an alkaline 9v is approx 1 Amp hour. So that give you 25 - 50 hours of run time. In practice, you'd get less, 'cause the 1 AH rating assumes a much slower (...) (24 years ago, 19-Dec-01, to lugnet.robotics.handyboard)

|

If I use a separate battery supply for the motor outputs, will a single 9v battery provide sufficient power for the rest of the Handyboard instead of the 8 AA cells (9.6V)? (24 years ago, 19-Dec-01, to lugnet.robotics.handyboard)

Alternativeley you can continue using the valve with the old style pump and have an air tank (if you own two) on each side i.e. one that holds the vaccum and one that holds the pressureized air. but... theres still the problem of flipping the valve (...)

(...) Yes, you can store vacuum. But all you can store is 1 atmosphere. So a little blue tank with 4 atmospheres has a lot more storage than one with negative 1 atmosphere! Also, it's real hard to make vacuum, in the real world. I once built a (...) (24 years ago, 18-Dec-01, to lugnet.robotics)

(...) Also, the external pressure is usually fairly fixed (atmospheric pressure) and there's a lower limit to the internal pressure (absolute vacuum), but no intrinsic upper limit (though it is limited by the strength of the tank). Therefore a (...) (24 years ago, 18-Dec-01, to lugnet.robotics, lugnet.technic)

Hi all. I have finally gotten around to yet another site re-design. I have added some new areas including pics of my climber robot, and a reviews section. link - www.astolfo.com/lego Dave (24 years ago, 18-Dec-01, to lugnet.robotics)

Instead of pushing a pneumatic switch back and forth, you can use the old non-return valve: (URL) the pump to the middle hole, connect the air tank to the left hole and leave the right hole free. The old style pump will pull air out of the tank and (...) (24 years ago, 18-Dec-01, to lugnet.robotics, lugnet.technic, lugnet.build)
