Introduction: My Awesome Little Boombox

About: Hey! My name is Roey Leon, from Tel Aviv, Israel. On my free time, as a hobby of mine, I love building stuff from scratch. It always starts with a crazy idea, and then I realize that it`s too Dangerous / Unach…

Hey everyone


Due to my recent success in building my first Boombox ( you can view it in my page ) , i got some extra spare time , so i decided that the best way for me to utilize it is by building something !

i saw those two crappy cheap speakers that i got on eBay for 35$ ,so i  decided to do something with them , instead letting them fill with dust


Enjoy!






Step 1: Shopping List

1 .80x80 cm Plexiglas 
2. Screws and nuts  - about 70 pieces from each
3.Battery 12V 7 amp
4. set of speakers - invest at least 50 $ if you want to get a decent sound
5. Amplifier - got the Lepai T2020+ AMP- excellent amplifier
6. Wires for the speakers
7. soldering iron and soldering wire
8. different angles and angles - different sizes
9. Time , patience , and little self confidence .
10. Clamps
11. Hot Glue
12. Drill + set of drills 
13. Coffee !!

this whole project took me something like 16 hours ( working time ! ) - two days in total

Step 2: Sawing the Plexiglas

Carefully saw the Plexiglas .

I broke at least 3 pieces during the sawing till i got the hang of it .

the most important thing to do is use a sawing blade that is meant for metal - it has small Saw-tooth.


Step 3: Start Cutting the Angles According to the Size of Your Boombox

Step 4: Start Attaching All the Angles , Side by Side to the Plexiglas

Step 5: Start Screwing the Bolts With the Nuts - Phase 1

this first phase is just for the adjusting of the pieces together.

this is the Tedious part , it takes a lot of time ! to match each angle to the Plexiglas , it takes a lot of time drilling the holes in the correct places .

 overall after building my first Boombox i took my time with this one , drilled each and every hole in the correct place and made sure not to brake the Plexiglas or drill in the wrong place - it happened a few times.

Step 6: Add Hinges for the Upper Case

Step 7: Attaching Everything Together Phase 2

place all the bolts and nuts and all the pieces of the project till it completed.

 make sure that  it works , and sound OK, and make sure that it is built OK .

 then , disassemble everything  so you can tear off the Plexiglas protection cover  - Nylon 


Step 8: A Few Extra Views -

Step 9: Create a Switch for LED Light

took one little switch , connected ( soldered ) it to two wires and one small LED stripe.


 look even better !

after connecting the wires , i putted Shrinks ( to protect the wires )


then i heated them with a heat blower to " shrink " them

andddddd connected it to the Plexiglas 

Step 10: Create Two External / Internal Bolts for Charging

after hours of using the Boombox , i will need to charge it via an external charger ( 7$ on eBay )

Instead of removing the battery each and every time , i drilled two holes on the side of the Plexiglas , inserted two bolts and closed them.

 Then , i connected the internal wires of the battery directly to the bolts , and from those bolts to the Lepai amp.

Left bolt  -positive 
Right bolt  -negative 



Step 11: Gluing Wallpaper on Bottom Angles

i glued some wallpaper on the bottom Angles , it`s much better looking then the plain steel 

Step 12: Final Assembly

Slowly start to assemble everything back together , make sure not to scratch the Plexiglas.




Step 13: Final Assembly - Final!




Step 14: Seal With RTV the Sides of the Boombox

we need to seal off any  small opening the Plexiglas  , in order to create a sealed space - for the Reflex port  to operate properly
