IPhone Sound Amplifier

Hey Guys ! This a one of my older project and unfortunelty I do not have too much pictures showing the building process, but I’ll try to compenstate this with a detailed description. In terms of duration this was a quick project it took me 2 afternoons to complete.

The idea !

The idea wasn’t mine, this project was more about building a replica of the below picture. I’ve seen this project for the first time on the kickstarter website  and I’ve found it quite challenging to try to build one.

Here is the original link.

To be honest, I was a bit skeptical that this “thing” can work so I was more than motivated to try to build one.

Building the amplifier

I’ve started off with building 5 different size of circle templates (jigs) to be able to use my hand router to cut out the holes.

Speaking of materials I’ve managed to find some oak timber so this was the choice.

After I’ve finished to cut out all the 5 circles I’ve changed the router bit to a 45 angle bit with a follower ring and routed the edge of each circle.

This being done, I glued togheter all the 5 pieces and after a bit of sanding I’ve ended up with the below picture:

Final steps

To plug in the phone I’ve made a grove to fit an iphone 5. The back part can be detached so it’s quite easy to adapt to iphone 6 which is wider. (unfortunately I have not picture with this part)

When the central part was ready I had the idea to put some wheels to each side :). The wheels were made from remained oak timber and were rounded on the lathe.

After a couple of days I had the idea to do some further enhancements to make it even more usefull. The problem I’ve noticed was that I couldn’t keep my iphone in the amplifier ‘all the time’ (e.g. during the evening) because I had to take out to charge. To solve this issue I’ve managed to integrate the charger cable into my amplifier.

The enhancement came with two great things:

  • you could use the amplifier to charge your phone
  • if you set the morning alarm the wake up sound will be amplified and you and your neighbors will jump out of the bad 🙂 . I’m joking, it’s not that loud, but it’s quite nice.

Before wrapping up I’d like to post a couple of pictures related to similar topic.

Ipad support

This is a 20 minutes project so I have no picture just the final product. The short story is that my kids are ‘ipad’ maniacs’ and love to watch cartoons on the ipad. Before building this support they always improvised to find variouse objects to hold the ipad in vertical position.

I’ve used some left over pieces of wood (oack and cherry) and cut them on the circular saw. I haven’t followed any design, I’ve just built what crossed my mind. 

After the glue dried, I did a bit of sending and applied 2 coats of finising paint.

Here we are: Wood Ipad support in 20 minutes !

    Hi, you have some really great work here! I love the amplifiers. I also wanted to make one of my own with the CNC machine I can use at school, but wasn’t sure what bit you used and if you set the speed really low, because I’m afraid the wood is just going to break while trying to make holes/pockets. If you can share the setting you used for your project, that would be great! Thanks!

      Hi Kim. I’ve used a standard 3mm end mill bit on the full speed, 40 000 rpm. I’ve used beech wood which is preatty hard and I had no problem.
