Can you boast of making things with your own hands? Below you will find several instructions which will guide you through the construction process of a subwoofer and a telescope.
Sure, buying a subwoofer is a simple thing. But don’t you think that making it at home is much more interesting? First saw an old bookcase.
Make an aperture.
Install the driver units.
This is the final variant.
Don’t forget to use supports so that the appliance could be evenly held.
A lower part of the frame. All the holes were sealed up with hermetics.
Foam plastic is added to the frame.
Apertures for Bassreflex: 110 and 75. The first one is intended for a plastic tube.
Or a chips can.
As the can was short it was decided to make it longer with the help of epoxy glue which is dried for 24 hours.
Filling the can.
Assembly and preliminary installation.
Assembly is continued.
Foam plastic is glued to the box.
The ready-made construction is connected with Microlab H500d.
Fixing a paper band.
First variant of connection.
Frames for Bassreflex.
Covering the left seams with glue.
Polishing and drying.
The back cover needs to be separated or cut in this case.
Fixing the band. Don’t forget that the bad must be of a good quality.
Next day it was obvious that some mistakes still were made. The aperture was made not in the right place. The bottom was fixed in the wrong way.
Coupling the new invention with dynamics of Monitor Audio Silver RX6.
In a couple of hours the passive appliance was supplied with an amplifier and a power block.
Fixing the connectors.
Background view, final variant.
The process was followed by adding conditioners. The choice of an amplifier was far from being successful as it kept making a loud screeching sound and required another lowering filter. Besides, sound can be lost at ultimate volume and if you don’t like it tool loud don’t pay attention to it.
This very telescope was made in a regular apartment. It took several years for its inventor to assemble it.
This equipment help in telescope production.
Having passed through molding stage.
Getting ready for polishing. For this purpose colophony was used where resin was substituted for condenser lense. Steel disk was taken as a base.
Other examples of good work.
Plates are fixed on magnets making it convenient to change the aperture size.
Checking the parameters.
The frame is ready, now it’s time to fins nice screws.
The view of a picture depends on the eye position. Then it’s needed to find an optimal position and enjoy the view. Spherical defect is not noticed and is small even if present.
It is covered with a film now but rough surfaces can still be observed. The variant is not final though.
Now the telescope is ready and can be taken outdoors to have a look at some nebulosity located far from the lights of the big city.
