Building A Monitor Soundbar (DIY Project With Video)
OK, to start this article, I going to state that this is not about an electronic design or repair. Its’ more of an assembly…
The reason I started this project was because in my automotive workshop, I have a desktop computer and a wall mounted monitor. This had worked well for several years, but I had noticed over the last few days, the screen would disappear after the monitor had been running for any length of time. I started working on repairing it, but unfortunately, it took longer than I expected.
No problems, I had a spare monitor that I could use until I repaired the original. The spare, unfortunately, didn’t have speakers, nor did the desktop computer.
Yes, I could have spent more time trying to repair the original monitor, but I had an idea in my head that wouldn’t go away!
For some time, I had a little 100W amplifier that I had purchased. Now was an opportunity to put it to work. I also had disassembled a laptop computer that was unrepairable, salvaging parts that I could reuse.
I’ve always enjoyed timber work & have built furniture, restored our house & other projects. Now was the time to combine both timber work with electronics.
I came up with a basic design and went to work.
I had some spare MDF timber that I was able to cut to size.
Using masking tape helped hold the pieces together temporarily for testing.
At this point, I made a template to house the laptop speakers. I enclosed them in their own little boxes to enhance the massive base notes…….
Using a hole saw gave the basic shape, while a jigsaw was used for the final shape.
I wanted the front to have a grille look of sorts. I bent up some window screen mesh & this became the soundbar face.
I was not happy with the placement of the power supply to the amp. This was simply done by a terminal block that did not allow for easy disassembly.
I purchased a power supply that had a barrel jack. However, due to the size of the female barrel jack that would be soldered to the board, this would interfere with the soundbar housing. This was solved by facing the terminal block backwards and remotely installing the barrel jack into a different section of the soundbar. This was then glued into place.
After allowing the glue to dry overnight, the soundbar could be assembled & tested. Considering all it had to do was provide sound from the computer, it successfully carried out the task. It was light enough to not put excess stress on the wall mounted monitor.
It has been working flawlessly for almost a year now & I am more than pleased with the results.
