[...] this is my first threat
I'd like a double shaft motor to be in between two billboards so that both will spin at the same time and stop at the same time.
I want it to be powered by a small solar panel at the top, at the same time charging a storage battery.
When it becomes dawn to night time. I want a sensor to sense that and turn on small LED lights.
I don't know what the board/module thing is called that one programs. For this example to control the motors. (can the RPM of the motor be controlled this way?)
What kind of motor, how big of a motor, what battery, what solar panel, sensors that detect darkness. Etc...
I know I'm a newbie with this, and I hope there is someone with enough patience to guide me a bit here if you'd be so kind.
Here's another place to get ideas and ask questions. Lots of projects shown here as well.
Boring? No. There are plenty of challenges there.Suggest you start reading the tutorials on this site. You will find most of the background information you need to get going. Suggested starting points include Microcontrollers, DC Motors, Photoresistors and Dynamics.This should give you some ideas.
Hi,Now we're scared
I'd place them on a common axle with something like a bicycle chain leading to a single shafted motor mounted lower.
That won't do, unless your apprehension of "small" is different from mine.How large a panel it will take depends on the needed power for the motor, LED's etc.You also need to factor in that a panel (and the boards) need to cope with whatever wind speeds are possible where you plan to place it and the higher up, the more wind force (usually).
You can use the solar panel to that effect as well, no need for extra sensors.
A microcontroller is what you want to program and yes, it can be used to control speed - but I gather you just want a single speed, so it's best to use gearing to keep the power at max.
A common DC motor would be the obvious choice, as it is quite straightforward to use.The size of it can be found when the size, weight, speed etc. of the boards and the construction of the spinning axle is planned through.The battery will have to be of the voltage needed by the motor, with a capacity suited to buffer the thing through the night (following a rainy day or several) and the solar panel will have to be calculated for this as well and it has to be able to deliver throughout the temperature range it will see.
No problem. I assume you do have the basic tools and instruments (a DMM at the very least)?
you might want to go to society of robots website and look at the parts list. that might ring a bell on what the parts are called.
Didn't think of that, and should give the desired motion now that I've changed my mind about something. I don't think I should have the boards spin. I can't imagine how I would have LED's lighting the boards if they are going to be attached to the board's frame with wires. When it comes time to spin, the wires are going to tangle unless I make it spin clockwise and then counterclockwise with enough wire that it doesn't tangle up, that should work, however I like the idea of having them only swing from left to right (like a grandfather clock) as my first project.
Should keep things simple no? Is this rocking motion programmable? Or will I know need two different motors? From what I know in order to make a motor spin the other direction you switch the wires over.
My small is, hmm, the size of the panels you see on top of the emergency call boxes in some freeways. Is that still too small?
The height of the pole won't be too high up, up to the same height of a stop sign or a bit higher to keep people from trying to smack or break the thing. I'll try my best to make the boards as light as possible, I'm thinking a thin aluminum frame with a light weight clear plastic panel and make the thing water proof, have an opening to slide in custom made banners.
That will save me some money and that is always good to know. More money for a bigger panel?
I assume a low voltage microcontroller will be the most ideal, with the least of features since I only want it for programming the motors "rocking chair" motion and the LED's. If I can save battery life and money here I'd be happy. What would you recommend for this?
The motor would have to have good torque I assume, yes?
I was thinking of getting a used electric ride on toy cars for kids, those things have very strong motors and it even comes with a battery and the charging port, saves me the hassle of shopping around plus those motors go forward and backwards all ready so the wiring should be set up for me? (I just thought of it a few minutes ago )
The LED's would only have to be on until 2-3 hours of night time then they would be turned off or let die off. Hopefully that would make things simpler for me since the charging part seems like the highest challenge. It won't be operational during rain, I will just have to accept that, there wont be any way to wire it to a DC Jack where I want to place it.
My DMM broke as it was a harbor freight one and not very durable. I have lots of automotive tools as my main hobby is working on my older cars, none of them run at the moment I have a buddy with a mig and tig welder, DMM, sodder, I should be fine.
Once again thank you for your time inputting informative, helpful, responses. I will start gathering parts once I know where and what to get.
