Creativity knows no bounds and this seems to be true in the case of Sparebots. Sparebots are more commonly referred to as Life of Sparebots.

Sparebots are actually spare bits and as the name suggests are actually bits of spare electronic parts. These spare parts may be bits of wire, solder, resistors, leads, diodes and capacitors; used creatively to depict beautiful Sparebots.

 The spare bits are arranged in such a way that they look like real life forms. A spare battery may form the body of a Sparebot, while wires may be twisted to look like its arms and legs. Thus a sparebot is formed and this may look realistic too.

There are a number of photographs on the life of Sparebots. These photographs highlight the creativity with which Sparebots are made. These Sparebots depict common life activities in new light. The sparebots are fast becoming a rage on the internet as many people find them interesting and funny.http://www.suntan.com.hk/

Aluminum is used for the electrodes by using a thin oxidization membrane.

Large values of capacitance can be obtained in comparison with the size of the capacitor, because the dielectric used is very thin.

The most important characteristic of electrolytic capacitors is that they have polarity. They have a positive and a negative electrode.

[Polarised] This means that it is very important which way round they are connected. If the capacitor is subjected to voltage exceeding its working voltage, or if it is connected with incorrect polarity, it may burst. It is extremely dangerous, because it can quite literally explode. Make absolutely no mistakes.

Generally, in the circuit diagram, the positive side is indicated by a "+" (plus) symbol.

Electrolytic capacitors range in value from about 1µF to thousands of µF. Mainly this type of capacitor is used as a ripple filter in a power supply circuit, or as a filter to bypass low frequency signals, etc. Because this type of capacitor is comparatively similar to the nature of a coil in construction, it isn't possible to use for high-frequency circuits. (It is said that the frequency characteristic is bad.)

The photograph on the left is an example of the different values of electrolytic capacitors in which the capacitance and voltage differ.

From the left to right:

• 1µF (50V) [diameter 5 mm, high 12 mm]
• 47µF (16V) [diameter 6 mm, high 5 mm]
• 100µF (25V) [diameter 5 mm, high 11 mm]
• 220µF (25V) [diameter 8 mm, high 12 mm]
• 1000µF (50V) [diameter 18 mm, high 40 mm]

The size of the capacitor sometimes depends on the manufacturer. So the sizes shown here on this page are just examples.

In the photograph to the right, the mark indicating the negative lead of the component can be seen.

You need to pay attention to the polarity indication so as not to make a mistake when you assemble the circuit.
