Introduction: Mason Jar Portable Speaker & Guitar Amp

Let's face it: the speakers on your phone & laptop aren't loud enough. So grab a Mason Jar Speaker KIT from Trash Amps (www.trashamps.com) & build a Mason Jar Speaker to play tunes from your smartphone, tablet and laptop. BUT WAIT: it's also an electric guitar amplifier! Plug in & bust out those wicked solos. Great first project, you'll have music after 21 solder joints & some simple assembly. Impress your friends with a speaker you built with your own hands!

Time Required: 1 hour for a beginner

What you'll need:

  1. Mason Jar Speaker KIT from www.trashamps.com ($39)
  2. Wide mouth mason jar with the metal ring that holds the top on
  3. Soldering iron
  4. Solder
  5. Phillips head screwdriver
  6. Wire clippers
  7. Ruler

More details about the Mason Jar Speaker KIT:

  • High Quality, High Volume Sound – ample sound for your bedroom, kitchen, or backyard BBQ. People are always surprised at the amazing volume and full range sound created by the 2 inch full range speaker and 2.4W amplifier (140 to 20 kHz).
  • Compatibility – works with any device with a headphone jack (smart phones, iPods, tablets, etc). Also functions as an electric guitar amp.
  • Fun for both beginner and advanced makers – check out the assembly video and text instructions below. Only 21 solder joints (basic soldering knowledge required). Assembly requres less than 1 hour from start to music.
  • Made in USA – high quality product with USA sourced materials, prepared in California by two dudes who love speakers.
  • Modular Design – headers connect the speaker and battery pack to the circuit board, so you can easily try different configurations or replace a broken part.
  • Sustainable Enclosure - most portable speakers come in a plastic box, which is a problem because less than 7% of plastics are recycled in the US. The glass Mason Jar is Earth-friendly because it is easily reused and recycled, plus you might already have one at home.
  • Strong, High Quality Cord – connect your device, fits in any 3.5mm headphone jack. Use ¼” adapter for guitar.
  • Long Battery Life – 3 AAA Batteries give you about 15 hours of jam time/easy listening (not included).
  • What's Not Included – make sure you have access to these items: soldering iron, solder, phillips head screwdriver, wire clippers, ruler and 3 AAA batteries.

Step 1: Getting Started

Make sure you have everything you need:

  1. Mason Jar Speaker KIT from www.trashamps.com ($39)
  2. Wide mouth mason jar with the metal ring that holds the top on
  3. Soldering iron
  4. Solder
  5. Phillips head screwdriver
  6. Wire clippers
  7. Ruler

Each step is accompanied by an image which you can reference as you complete that step.

Step 2: Solder 3.5mm Jack to PCB (5 Solder Joints). Make Sure Part Lies Flat Against PCB.

Step 3: Solder Right Angle Male Header to PCB (2 Solder Joints). This Is the BATT Connector.

Step 4: Solder Straight Pin Male Header to PCB (2 Solder Joints). This Is the SPRK Connector.

Step 5: Solder 2x 5mm LED to PCB (4 Solder Joints) and Cut Off Extra Leads.

Step 6: Solder Switch to PCB (8 Solder Joints). Place Switch on the Side of the PCB Marked "Switch on This Side for Jar KIT". Make Sure Part Lies Flat Against PCB.

Step 7: Attach Battery Holder to Wooden Piece on Bottom of Speaker With 2 Flat-head Screws. Do Not Over-tighten. One Extra Screw Included.

Step 8: Attach Speaker to Wooden Top With 2 Button Head Screws. Do Not Over-tighten. One Extra Screw Included.

Step 9: Attach PCB to Wooden Top With 3.5mm Jack Nut and Toggle Switch Nut.

Step 10: Plug in Battery Holder Header to Right Angle Male Header. Plug in With Correct Orientation: Red Wire = Positive, Black Wire = Negative. Hooking This Up Backwards Can Damage Your PCB!

Step 11: Plug in Speaker Header to Male Header. Plug in With Correct Orientation: Red Wire = Positive, Black Wire = Negative.

Step 12: After Ensuring Battery Holder Is Connected With Correct Orientation, Insert 3 AAA Batteries (not Included) Into Battery Holder. Battery Life Approx. 15 Hours.

Step 13: Great Job, Your Speaker Is Ready to Rock!

Very cool. I did not see the schematic or parts list for the amp. Can you upload those again?

While we've both created a Mason Jar Speaker, I'd imagine that our speakers sound quite different based on the audio amplifier, speaker, and power source you've chosen. We've got a high quality 2.4W Class AB amplifier with a custom built speaker driver, the sound is surprisingly good from our speakers. Also our speakers have a different appearance when finished. Ours has a laser cut wooden top and looks very professional. Our KIT is reasonably priced and we provide everything you need to make the speaker. The cost is more than your project, but the person doesn't have to acquire each component individually. You have a cool project. Keep up the good work!

Thanks! In the past we also built speakers from soda cans, beer cans, chinese takeout boxes and more! We get our new product ideas from looking inside the recycling bin and the trash can :-D Thanks for your comment!

Very cool! I like that you can use whatever mason jar you happen to have on hand!

Thanks Austin Powers! It can really save on the manufacturing if you don't have to manufacture the speaker housing - which is usually a black box of plastic! Also, if you use your own jar for the speaker housing, it really cuts down on the shipping weight! Thanks for your comment!

Plus I imagine you could get very creative with the decorating :)
