Fan Controller Using Just Two Component
The Maxim MAX 6665 (www.maxim-ic.com) provides a complete temperature-dependent fan controller. It can switch fans operating at voltages of up to 24 V and currents of up to 250 mA. The IC is available from the manufacturer in versions with preset threshold temperatures between +40 °C (MAX6665 ASA40) and +70 °C (MAX6665 ASA 70). The device’s hysteresis can be set by the user via the HYST input, which can be connected to +3.3 V, connected to ground, or left open. The following table shows the hysteresis values available:
HYST = Hysteresis
open = 1 °C
ground = 4 °C
+3.3V = 8 °C
open = 1 °C
ground = 4 °C
+3.3V = 8 °C

The other pins of the SO8 package are the FORCEON input and the status outputs WARN, OT and FANON. The test input FORCEON allows the fan to be run even below the threshold temperature. The open-drain output WARN goes low when the temperature rises more than 15 °C above the threshold temperature, while the open-drain output OT indicates when the temperature is more than 30 °C above the threshold. The push-pull output FANON can be used to indicate to a connected microcontroller that the fan is turned on.

Cheap Electronics Component for Amplifier Application
Cheap electronics component for amplifier application, it is simple to be made for speaker active . The sound quality even this Mini Amplifier TDA2030 quite satisfactory for a portable audio system.
"The series of Mini Amplifier TDA 2030 "The series of mini amplifie can reproduce the power output of 14 Watt with 8 Ohm speaker load. The series of mini-amplifier can be supplied with ource voltage of 12 volts - 15 volts DC. more details, see the following series of pictures.

Component placement design
Here I will share about the arrangement of components in the box. That where the components are a series of audio amplifiers that use relatively large components, which consume a lot of places in the box to the amplifier.
But in this post I just gave inspiration only in the arrangement, or design place for neat, clean and have good audio output as well. please see image below.

Description
1.AC 220V terminal
2.Switch on/off
3.Transformer
4.Diode
5.Capacitor elco
6.PCB kit amplifier
7.Heatsink
8.Master Volume
9.Terminal input output.
Then this is the image of the booster amplifier using 2 sets of Sanken 2SC2922 and 2SA1216 transistors, which has a high output power.
