How to make a sound amplifier yourself? Making the case

First, it is necessary to prepare a body in whichall electronic device will be protected from various mechanical damages, moisture and other negative environmental influences. Since we mentioned in the list above the protection against damage, this part we will be made of metal, and to avoid weighting the device, you can apply several aluminum corners. After that, cut the workpieces and make vertical racks. As for the dimensions, the thickness of our amplifier will be about 5-6 centimeters, while the dimensions of the glass cover - 4x1 millimeter. The height of the entire post is about 5-5.2 centimeters. When constructing the body of the element, do not forget about the horizontal elements of the frame. As the connecting elements for the assembly of the structure should be used 3-4 screws, preferably a series of M3. It is necessary to make two goners on one of the pillars, the bottom and the back wall. To do this, you will need a jigsaw for metal and a 1.5-millimeter aluminum sheet. All this is then fastened to the structure with screws.

Also in the question "how to make an amplifier forcolumns "it is necessary to pay attention to the front panel. To do this, take a strip of aluminum 5 mm thick and make a bar that will hide the entire mechanism. To give the device a "human" look, paint it with some paint in an aerosol can.

How to make a sound amplifier yourself? The commutation board is made as follows:

1. The laser printer prints a drawing of the future card with a scale of 1 to 1.
2. The back side of the image paper is placed on a piece of fiberglass (it is important before it to degrease).
3. The result is transferred to the foil, which is then smoothed by a heated iron with a temperature setting set to the maximum value.
4. After 5 minutes of treatment, the board cools down, and the paper is then removed with water. At the same time, the toner will melt and adhere to the foil.

The last stages

After that it is necessary to take care of the board forcapacitors and insulation.
