Help with fibreglass – polystyrene moulding?
Hey im amking a rc boat hull out of polystyrene and then moulding with chopped strand fibreglass. i finished one part of the hull ok and then i had to get more resin and i got a diferent brand i applied it and finished the other half but a while later i checked it and the fibreglass had gone hard but seperated from the foam and had almost half eaten the polystyrene away. this probably happened because there was some type of solvent in the resin, in future how could i stop this from happening like is ther some coating you can put on polystyrene before coating?

Solar Panel – DC motor – Rated Power ? Functionality ?
I have a solar panel 7.5V 1.25W 150mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack – 7.2V 1800Mah.
The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * 1.8Amp) = 12.96 Watt.
Would two of my solar panels run this DC motor ?
are my calculations or understanding correct ?
do lend a hand dear ”world”
Yes i assumed the motor was at 1.8Amps from the 1800mah spec the battery had, my bad.
Sorry for the english mishap, was in a rush.
I really do not know how to find out about the motor spec, it is a rc boat i purchased and now planning to use solar to run it, in other words removing the battery and only relying on solar energy.
pretty confusing this is!
i connected the solar panels but the motor did not respond. i suppose you are right, i need more then 2 piece of them solar panels.

Rechargeable batteries?
Hi,
I just recently boat an RC boat. After charging the ni-cad battery for approx. 2hrs, the boat didn’t work. The instructions state that the battery should be charged for 5 hours. Should it make a difference if I only charged it for 2hrs? Or do you suspect there is an issue with the boat/battery?
Thanks
So, there’s a chance I’ve runied it?!

How would a 14 year old (me) get into (the basics of) electrical engineering?
Well, first off, I’m not sure if it’s electrical engineering, or electronic engineering. Actually, I don’t know if it’s either. I guess I’ll describe it a bit.
I’ve always liked taking apart broken electronics (such as CD players, portable games, digital cameras, etc), one time I took apart a CD player and a cassette player, and made a top that spun for 3 minutes straight. I also broke my game boy advanced about 4 years ago, so I took it apart and fixed it somehow. About a week ago I found a old RC boat that has been in my room for the past 3 years, and you couldn’t turn left, only right. So I took it apart and fixed it.
Just small things like that. And actually, my dream is to make one of those war bots, and terrorize the neighborhood cats (and kids, hehe). Would that be robotics, would I have to learn electric engineering too? I really don’t know much about it, I’ve never had any lessons or anything like that. I do have a electronic 200 in 1 thing that lets you build all kinds of things with pre-made pieces, that you just snap to each other in the right places and such. It’s called “Kid Inventor Creative Electronics Kit”. I’ve had it since I was about 10, and it seems more like something for littler kids, but I never really paid attention to the lessons, I just tried to make the things in it that had instructions. I never read how it works or anything.
To get into electrical/electronic engineering, does it require a lot of math? I’ve always been kinda bad at math, maybe this will give me the motivation to get better at math..
Any help, info, or tips would be greatly appreciated. The only bad thing is I can’t spend very much, so free is best, but cheap is ok too.
I’m home schooled, 14, and live 20 miles from a actual town. Does that effect anything?
Thanks!
Oh, I forgot to mention, I would rather do it as a hobby/side job, but that could change.
That’s one thing I was kind of wondering, if people started out by just taking things apart and trying to fix/mod them.
That’s pretty much all I wanted to know, but one last thing: Is there some websites out there made specifically for tutorials (videos?) on how to do specific (beginner) things? At wonderhowto.com there’s plenty, but not quite what I’m looking for.
Thanks!
