You couldn't own handguns until recently. DC enacted ban in 1976, that banned many types of guns, but that law was recently ruled unconstitutional by the supreme court. In theory, you can now own any otherwise legal gun in DC, but I haven't heard any reports yet of what difference the SCOTUS ruling has made.
Please consult the DC Handgun Info blog at http://dchandguninfo.livejournal.com. It has links connecting you to D.C.'s Metropolitan Police Dept. Gun Registration Office, where to shoot, where to train, links to pro-gun blogs, etc. You may own long guns as well as handguns. The handgun (specific model number and color) must appear on DC's approved lists (combined from the approved lists of Maryland, Massachusetts, and California) and no others, unless you plan on suing the District of Columbia. If you do not have any training, you need to get some. DC has made it expensive and cumbersome to register a gun, and the process can easily add $400 to the cost of your gun.
No
No, skateboarding itself is not illegal. It is illegal only if you skate on private property or in places where it is prohibited.

A dc series motor can work on dc and ac because dc motors are totally reversible.
Chicago and Washington DC in the US
Virginia & Washington dc. Military bases.
Yes, they are illegal in DC. "Around there" are the states of Virginia and Maryland, where they are legal. Of course, you can DO things with them that are NOT legal in a heavily populated urban setting.
The people in DC decided to give up their right to decide what was best for themselves.
None that come to mind.
No! Super illegal
Transformers don't work with DC supplies - they only work on AC.
Yes, if the fan is designed to work on DC voltage, otherwise no.
