Introduction: Amplifier Dock

Amplifier Dock is a modern lo-fi solution to music listening inspired by Cradle to Cradle thinking. Unlike similar consumer products, Amplifier Dock can be manufactured and eventually discarded with minimal production of waste.

Step 1: Materials and Tools

Materials

Hardwood block at least .38" x 2.50" x 10.00"

A Bowl roughly 6.25" in diameter and 2.50" height

2 10-24 length flat head machine screws

2 10-24 hammer tee nuts

A small cut of 1/8" thick wool felt


Wood Working tools

Wood planer

Table saw

Miter saw

Belt or disc sander

Drill press

3/16" Drill bit, 1/4" Drill bit, 3/4" Fortsner bit, Countersink bit



Hand tools

Pencil

Tape measure and Square

Circle template, compass, or a US dime

Block sander

Medium and Fine grit Sandpaper

Craft glue

Mallet

X-acto knife

Awl

Step 2: Plane Hardwood to .38" Thickness

The hardwood portion of the dock is comprised of three parts, all of which are the same thickness.

First order of business: plane hardwood to .38".

Step 3: Cut to 2.31" Width

Next, use the table saw to cut your .38" piece to a 2.31" width (width of iPhone 4/5).

Keep a consistent speed while cutting to prevent burn marks like mine.

Step 4: Cut the Dock Into Its Components

Use the miter saw to cut your .38" x 2.31" piece into the three separate lengths measuring A) 6.00", B) 2.31", and C) 1.00". Make sure to account for blade thickness when measuring and cutting your pieces!

Reference the technical drawing (.jpeg and .pdf) for the remaining measurements and cuts.

Step 5: Prepare Base for Tee Nuts

Reference the technical drawing to measure out the holes on the bottom of the base. Next, grab the 3/4" fortsner bit and bore a shallow hole using the drill press. This step will allow the tee nuts to sit nice and flush on the bottom of the base.

Step 6: Drill Out the Base

You're ready to drill out the holes for the tee nuts to slot through. Use a .25" bit.

Step 7: Countersink and Drill 3/16" Hole

Being mindful of the end grain, take your three pieces and sandwich them together with some masking tape.

Mark points for the holes and using the countersink bit, carve out space for the flat head screws.

Next, grab the 3/16" bit and drill all the way through.

Step 8: Insert Tee Nuts

You're all set to make metal meet wood. Use a mallet or dead blow hammer insert the tee nuts.

Step 9:

Step 10: Round the Corners

It's coming together now!


Use the disc sander to round the corners to a .35" radius (radius of iPhone 4/5).

Step 11: Sand It Smooth

Use a medium and then fine grit sandpaper to get a nice smooth finish.

Step 12: Cut Wool Felt

The wool felt adds holding power to the dock by compressing and increasing the surface area in contact with the bowl. Use an X-acto knife with a sharp blade to cut out a rounded 2.3" square from the 1/8" thick wool felt.

Step 13: Glue Wool Felt to Cap

Use craft glue to attach your rounded wool felt square to the bottom of the cap.

Step 14: Poke

Use an awl, or similarly pointy thing to poke holes through the wool from the cap.

Step 15: Assemble

Grab your bowl, slide it in between the base and the cap, and tighten the screws until you have a tight fit.

Enjoy!

Genius. Realy. I always put my phone inside.

Very nice. Thanks for sharing.

Elegant design - nice planning, and wood working

very nice design!

OK mister smarty pants, what if you want to listen to music AND eat your cornflakes? Didn't think that through, didya?!

just make sure all the milk is out of your cereal bowl! (don't ask)

nice and simple, I like it - it's set me thinking, I wonder whether you could get a similar passive amp effect from a soda bottle... with some smart design you could even make it collapsible to fold flat for ease of carrying around...

Her is my quick take on the amplifier. Took about 10 minutes to build. Didn't need to use T-nuts. It's glued together so the T-nuts are overkill. Mine is made from a scrap piece of 1/2" baltic birch plywood I had sitting around. I'll make another with black walnut or mahogany and use a maple dowel instead of screws. I showed this to another teacher and she wants a bunch of them to display bowls. She liked the design a lot more than the typical easel stand you usually see on a bowl display.
Took me longer to go to the Home Ec department and find a bowl than it did to build it.:)
With the popularity of Iphones, androids, etc... this is going to be my next project in class as soon as we get back from spring break next week.
Really love the design. Kids will too.
