Controlling a servo with a Micro-controller?

So I decided to spend some time to make a "gimbal" in a very loose sense. Basically I was experimenting using a square wave oscillator to generate the correct PWM to have a servo rotate between 0 and 180 degrees when a tilt sensor is tripped. After some research multiple sites said having a 1ms pulse every 20ms would have it move to the 0 degree position. Great so I will make a oscillator pulses ~1ms on one side and 19ms on the other. However this does not seem to be working. I am curious if it is a fault in my math or if the tolerance on the parts I am using are just too wide to be any good. Here is a diagram of my set-up with the values a came up with. One spot that may be weak is that I just notice someone somewhere mentioned using 50Hz for the timing I just used that number when I calc my figures. Any feedback?  Also a side note is that I have been able to move the servo in one direction only and by accident ( in fact it's what inspired this project) when C1 & C2 were 2.2nF and the R1 & R2 were 10k potentiometers that I turned until something happened. Now that I am trying on purpose no results.

charge controller

Question for you all. I have a solar powered spot light I really like, when it's charged up. It has a 6vdc 4ah battery in it and I wish to re-charge it from my 12vdc system. Source power will be my 12vdc 160 ah battery and I'm thinking of using my extra 12vdc charge controller with a 3.5 ohm / 1 watt (or better) resistor attached to reduce the power to 6vdc. I believe that will work, but I don't know if the controller will know when the battery has reached capacity? The other thought is to just by-pass the 6vdc battery and run the light from the 12vdc system (using the resistor to reduce the power). Any thoughts?

My intention is to make the user select AUTO mode or MANUAL Mode. After selecting, the user will be asked to select speed and duration. So this requires a lot of loop-inside-a-loop, if-inside-if etc. When I'm using push button, the microcontroller cannot read the command when the second button is push. I heard, if using push button I need electronic relay.

I don’t know much about the wireless connection and battery to make these things. I know I’m sounding like someone that doesn’t have a clue about these things and it’s true, I want to learn it and make this controller. If someone can tell me more about this sort of project or tips me to a tutorial or something it would be excellent.

Heating Control

I have been thinking for some years now that I would like to have finer control over my central heating. The problem Now we are older we feel the cold more so in winter the heating is on all the time. This means that we have to keep altering the thermostat on each radiator at different times of the day or just leave them and so waste energy. One method means wasting energy but the other means rooms will be colder than we want initially.   The system and what i have We have a combination boiler which has a digital timer and also on the panel are temperature controls for hot water and radiator temperature. Each radiator has a thermostatic valve so each room can have it's temperature set independently. I have a computer which runs 24/7 and also a bit whacker which I can control via python code and electronics has been a hobby for over 50 years My idea I would like to have some system which would allow me to adjust each room temperature via computer control.   Possible solutions Solution 1 Fit a stepper motor to each thermostatic valve to adjust it at different times of the day/night. This would allow precise control but would be quite expensive to set up. Solution 2 Fit a small structure round each valve with a filament bulb or resistance wire in the bottom so that when power is applied to it then the temperature around the valve will rise and so the valve will close or, at least partially close. I think this would be much cheaper to implement but would have the small on-going cost of using power to the bulbs whenever the room temperature needs to be cooler that it would normally be. My initial plan Build a small structure around one of the valves with a low voltage bulb in it. It would have vents at top and bottom and so air would circulate. I have a portable digital thermometer so i could gather information and try different bulbs to see how much power would be needed and therefore what the on-going cost would be. Also try various shapes of structure to see what the effect would be.   So guys what do you think?

Remote Control Car Controlled By Computer

I'm doing a project where I am rewiring a remote control car remote to work using a computer interface. I've found a few tutorials on how to do it, but they all deal with a "button" controller, where the motion is controlled by pressing buttons rather than using a "pistol grip" controller, or one with a wheel to control turning and a trigger to control acceleration and deceleration. Has anyone tried this, or does any one know if I would be able to use the tutorial linked below with this controller. I highly doubt it would work, but I would like a better opinion.http://jbprojects.net/projects/rc/

Computer controlled crossover?

Hey guys, I've been wanting to ask someone about this idea for a while now. You know how you can get programs like SRS Wow that's built into windows media player? There are also other assorted Equalizer programs (with sliders) or for effect, to change how your music is playing. If these programs can do this merely with cpu power, is there a way I could have a source from the mic/input plug on a soundcard in one of my spare towers, and say, re-route it to the speaker/output on the card, but say, have a subsonic filter in place between the input and the output of the card, using only software? I'm pretty Effin sure this has to be possible, and yes I can take into consideration that there could be some considerable cpu usage for realtime playback. My goal would be to say set in place a 20 or 30hz cutoff point and then run that to my subwoofer amp, or use two seperate towers, and run my other subwoofers I have sitting around, but they need a higher cutoff point as they are only 8-10inch woofers. Could anyone lend a hand?? I know this has to be possible somehow.
