Building your Mason Jar Speaker KIT v4
Assemble the Speaker
Attach Speaker to Wooden Top with 2 button head screws. Do not over-tighten. One extra screw included.
Attach Battery Holder to wooden piece on bottom of Speaker with 2 flat-head screws. Do not over-tighten. One extra screw included.
Now grab your PCB and plug in the Battery Holder to the 2-pin Straight Male Header (BATT). Plug in with correct orientation: red wire = positive, black wire = negative. Hooking this up backwards can damage your PCB!
Plug in the Speaker to the other 2-pin Straight Male Header (SPKR). Plug in with correct orientation: red wire = positive, black wire = negative.
Now insert the PCB in the holes in the Wooden Top. Grab the hex nut and screw it on the Toggle Switch. Tighten with pliers if you have them.
After ensuring that the Battery Holder is connected with the correct orientation, insert 3 AAA Batteries (not included) into the Battery Holder. Battery life approx. 15 hours.
Insert your speaker into the Mason Jar and screw on the lid. The speaker is OFF when the Toggle Switch is leaning outward, as shown in the picture. We will test your speaker in the following steps!
Plug the 3.5mm Cord into your smartphone, iPod, or laptop computer and flip the toggle switch to MP3 Mode (straight up). The volume of the speaker is controlled by your device. If you hear music loud and clear, you’ve done a good job!
Plug in electric guitar with Guitar Adapter to test Guitar Mode (switch leaning inward). Turn the volume on your guitar up to 11 to get a great distorted tone.
Use the “output” to connect additional speakers for louder sound. This is commonly referred to as “daisy chaining.” The more the merrier!
Rock on dude!
Great job! Your speaker is complete, congratulations! We would love it if you’d share a photo or video of your speaker:
Go wash your hands!
After building projects involving tools and electronics, you should always wash your hands with hot water and soap when you’ve finished working.
