I've though about doing it with one joystick, but I'm happy with the way it drives now with two - It gives a little more control. Driving with your design may work well for some applications, but I need to be able to adjust the direction while moving (stopping one of the motors momentarily while going forward). It also lets me pivot around one tread or the other, instead of the center which is nice in tight spaces. With your plan, it would mean a complete stop before turning. I'll look into relays -- I'm new to building things like this, and so I don't know how or when to use diodes, resistors, relays, and so on. Using these would probably simplify things alot...my workarounds are pretty complex! Work your brain on this one, because I made it work on a different motor, (though I've found better switches and don't have to do this any more): Control a motor forward and backward: 1. Two momentary SPST buttons. 2. Batteries 3. Wire, tape, etc. Can you figure it out? No, because with only one set of batteries, you're either shorting the battery the whole time, or running the motor the whole time. I setup two sets of batteries, one for forward, one for backward, and did a very complicated wireing system. Wow, I wish I had a relay or a DPDT switch or something!

Maybe try changing the refresh rate, and see if it makes a difference. Start>Run... "control.exe Desk.CPL" Settings Tab> Advanced You can change the settings in there.

Is the Universe infinitely large? I've heard that it is "expanding," but I'm not sure what that means in terms of size. Mathematically, something infinite can be expanding, yes? If the Universe is not infinite, it is what? Very, very big? I'm not real clear on the basic concepts of this kind of theory, so point me to a resource if you can.

I'll do my best, because I'm not real sure if I understand all the way. I have two 4-directional joysticks that I was given by a friend. I only use the "up" and "down" of each joystick, to control forward and backward of each tread. The joystick is on a circuit board. It has (I think...) a SPDT momentary switch for each direction. A tiny red button that the joystick depresses when you push it forward. There are three connection points to the switch. One is "common" - always connected. The other two are toggled between each other. It is connected to the first one by default until you press the button and the connection switches to the other terminal. I might have to draw out a wiring diagram for this, because it is kind of complicated how I managed to get it to work forward and backward. I'm wireing both the forward and backward switch together, to make this work: The (+) lead of the battery is connected to both of the "common"-terminals, I think... It was difficult to figure out a way to make it so it never shorts-out (you would have to press forward and backward at the same time, which is impossible with the joystick) and it would work both forward and backwards, but it is possible. I have proof, because the car works, except for the problems described above. I'm sorry, I have to draw it out, and maybe look at what I did to explain the circuit I have any better. I'll draw this on Monday if I need to explain, as I won't be here this weekend.

haha! But the question was "What would happen..." not "What would you see...!"

I've built a tank-like vehicle and need help setting up the control differently. The drive-system of the vehicle is two independant motors, and each operate on 3 volts. I need to be able to control each of the motors forward and backward. Currently, I have a battery system where there are two seperate battery holders (2xAA each = 3v each). One motor runs off one battery set, and one motor runs off the other. The batteries are in the controller, and 4 wires go to the vehicle. However, I'm wondering if there is a better way to do this. Most toy vehicles have one set of batteries to power all the motors. The system I'm using works terrific, exept for consistant battery power. If I drive to the right more (use the left tread more), then that battery set runs out faster, and eventually I can no longer drive strait, but "vere" to one side, because one motor has slightly more power. Do you guys have any ideas of how to make this work better?

It's hard to say really, because so much is based on that strong force. Basically, you'd have nuclei and single electrons flying everywhere. No compounds, no bonding, because no atoms would have any electons.

One of my computers makes a very, very high pitched sound when it runs. It is so high pitched, that sometimes I think that I'm just making it up. But I prove myself wrong with I turn the computer off, and I can hear the noise stop, or when I turn it on, and I can hear it start. But otherwise, I don't notice it unless the house is silent.

Lead forms ions of 2+, usually...

It is a redox reaction, and you have to balance the electrons. Fe(II) will form Fe(III) and you will get Mn(2+). Sulfuric acid is not a catalist, but instead, it takes the Oxygen off of MnO4, so you get water instead of MnO2. You should be able to figure it out from there.

Do you want solid zinc chloride, or ZnCl(aq)?
