LCS-1M - A Low-Cost Hobby Oscilloscope
Next are the capacitors. The ceramic capacitors (brown discs in the picture) are easy - they are unpolarized
(i.e. you can put them in either way) and all have the same value (0.1uF).
More caution is required for the electrolytic capacitors (black cylinders in the pictures). First, there are two
different values - 1uF (the group of four placed around the socket on the bottom left side), and 100uF (the
other four). Second, those capacitors are polarized - inserting them the wrong way around will destroy
them. The silkcreen indicates the positive side (with a "+"), as is usual practice. Strangely enough, the
capacitors themselves have the negative side labeled (with a "-", the vertical grey stripe on the capacitors),
so make sure you put them in the right way.
