Need help identifying these components

Here's a picture of a board I'm trying to identify:

http://tabi.org/board.gif [100KB GIF]

It has 5 different kinds of components, and I have no idea what any of
them are. Could someone please tell me?

1) An orange component on the left, labelled "A5".
2) A black component next to it, labelled "A82".
3) Four smaller black/silver components, labelled "1002" and "1908".
4) Another black component in the upper-right, labelled "2A".
5) A larger black/silver component on the lower-right, labelled "820".

I assume these are basic components, like resistors and diodes, but
they don't look anything like what I used back in my college
electronics labs.

Any help is greatly appreciated.

Dunno, looks like a capacitor but they are usually unmarked. Might be a
resetable fuse?
2) A black component next to it, labelled "A82".

Probably a BAS21 diode
3) Four smaller black/silver components, labelled "1002" and "1908".

Resistors. The last didgit is how many zeros to add for the value in ohms
so 1002 = 10000 or 10k for example. Oh the 1908 will be 8061.
4) Another black component in the upper-right, labelled "2A".

Probably MMBT3906 transistor
5) A larger black/silver component on the lower-right, labelled "820".

Another resistor.

1)orange comp = tantalum cap
2) black,three legs = transistor
3) four smaller comp,blck = resisters and there vaslues on ohms
4) not to clear = could be anothere transistor
5) larger wattage 820 ohm resistor, maybe 1/2 watt

have fun

2) black,three legs = transistor

Diodes, voltage regulators, temperature sensors and brownout detectors
also come in the same package.

Pico-fuses as well.

What's an 8061?
Another resistor.

82 ohms?

Do you know what the A5 stands for? I've never heard of a tantalum
capacitor, so I looked them up, but I haven't seen anything that helps
me understand what A5 is.

A 1908 read right-side-up.

I expect it is a ceramic capacitor, not tantalum.

Some chip capacitors are marked with an alphnumeric code like that -
I've seen a list of value vs. code somewhere, but can't quiclky find
it now...
