Introduction: Easy Lego IPod Speaker for Less Than 2 $ !

Picture of Easy Lego IPod Speaker for Less Than 2 $ !

My sister wanted some speakers for her iPod. She showed me speakers she liked. It was some
speakers made with Lego... When I looked at the price...... 25+ bucks for a piece of Lego with some speakers.... I told her I could make a similar thing for ... free or almost... The only difference would be where the speaker would be located... on top instead of the bottom.

Step 1: Before Begining

Here what you will need to do the project :

- Lego block (will contain speakers) ( I took a 8 x 2 x thick lego block) - Found in my closet
- Lego block (will act as the back plate) ( 8 x 2 x thin) - Also found in my closet.
- 2 small speakers - I ordered 2 samples from Project Unlimited (Part number AS01508MR-R)
- Headphone jack (1/8") - Old one from a extension cable
- Hot glue
- Soldering Iron, Vacuum plunger, solder
- Dremel tool
- Needle-nose pliers, wire cutter, cable stripper
- Wires (you could use so telephone wires, would get the job done)
- Safety Glasses Important !!!!
- Spare time
- Patience

- Multimeter/Continuity tester

Cost of this project : .... 0 $ USD... which is also 0 $ CND or 0 euro... God I like 0. As I said earlier, I found my Lego block in my closet.... I had an old extension cable for the audio jack and I ordered sample speakers... so, every components were free... :)

But, I guess if you didn't have an audio jack... this could add up... 1 or 2 bucks... or 10 minutes of hard-looking in you house to find a broken pair of headphones.

Step 2: Modding the Lego Block

If you want to put some speakers in the Lego block... you'll obviously need to remove the plastic inside the block. I used the Dremel tool to do that.... and it wasn't hard, but it took me maybe ... 30 minutes to do it right. You just need to take your time, find a bit you are comfortable to work with and then, you are ready dremel the piece.

Warning : Make sure you open doors when you do this step. Burnt plastic smells bad !!!!! Also, be sure to wear safety glasses when you are doing it. Some hot plastic pieces could jump into your eyes.

Step 3: Fitting Speakers in Lego Block

Picture of Fitting Speakers in Lego Block

The dimension of the inside of my Lego block is 60 mm long x 13 mm wide x 8 mm deep. The diameter of my speakers is 15 mm.... 15 mm is wider than 13 mm... 15 mm won't fit in a 13 mm place. Well... I had to dremel 1 mm on both sides of the round speaker... it was so a tight fit that I don't need any sort of glue to hold the speakers inside the Lego block... they just don't move by themselves.

Step 4: Audio Jack

Now that you have a nice clean Lego block and that you have put your speakers inside, it's time to understand how we are going to connect our jack to our speakers.

If you kept the wires from the headphone, then this step is pretty useless. Your headphone jack will have 3 wires... Left, Right and Ground. Just make a continuity with each wires with the tip, sleeve and the ring to see what wire is what. If you don't have a continuity tester around you, you can build one easily with 1 led, 1 battery and wires. Continuity tester Instructables Now you just need to solder wires to extend ... the wires.

Now, if you are like me, and your audio jack doesn't have wires, you'll need to solder new wires to the different part of the audio. Just use the continuity tester ... or refer to my picture.

Step 5: Soldering Speakers With Audio Jack.

After soldering wires to the audio jack, it's time to look on speakers. On both speakers, you should have plus (+) and minus (-) signs. ou'll need to connect both minus of speakers together.

So, now you need to carefully solder the white wire to the left channel, the red one to the right channel, and the black one... on either of the speaker's ground. After soldering, try to play some music ! If it doesn't work, check your soldering... your + and - on speakers.

Step 6: Glue Time !

Picture of Glue Time !

After making sure everything is working, it's time to hot glue in place the jack connector.

Tip : Hot glueing is not like soldering. You can be pretty good at soldering........ but god, hot glueing can be terrible. Well, that's my case. If I could have weld the audio jack onto the piece of plastic, god I would have.

So... plug your glue gun..... wait for it to get hot, place the connector in place... make sure it's flat so it will be flush on the iPod's top. Hot glue's ready...... then hot glue the jack. As you can see on the picture....... I suck at hot glueing things. But, eventually the jack was solid.

After.. it was the time to clear the glue-mess... I took a small wooden stick and my dremel...... and the heat created by the spinning stick would melt the glue and I could remove it easily.

Step 7: Finishing

Now that you have a working, jack-glued, iPod Speakers. it's time to put that back plate on it and close.

From here, you have 2 options :

1. You can hot-glue the back plate to the case itself.

2. You can put the back plat there without any glue.

For mine, I tried to glue the back plate to the case... but it didn't work at all..... I even tried to glue it and use clamps to hold it... but it won't still do it. So now, the back is only snapped on the case. It holds OK... but not hard.

Expansion :

1. Running everything from the dock, just like the real thing. This implies having a huge dock connector, an amplifier chip, and a potentiometer (up or down the volume). Those parts take place in the kinda small lego block.

Thanks all for watching

Should I Put My real name in the sample speakers  requesting page?
and what must i type in the "title" field?

Agurri (author)menace42010-07-04

I don't see why you wouldn't put you real name. You are just ordering sample, it's not a crime ;). In the title field, I think it's either Mr or Ms, depending on your gender :)

TheBigT92 (author)2010-06-12

What did you put in for the application part of your sample order?

Agurri (author)TheBigT922010-07-04

I don't quite remember what I wrote... but it must have been something like Personal project...

dhvinay (author)2010-03-16

minimas1323 (author)2009-04-26

What did you put for the your company name when ordering the speakers?

cellopants (author)minimas13232009-10-07

[Your city name] Audio works.

lil_timmy1990 (author)2008-06-08

Super glue the back on. That would surely hold it.

Agurri (author)lil_timmy19902008-06-09

Actually... the problem is not how powerful the glue is... but where will it stick inside the case... there's nothing but some cables and speakers.... I had the same problem with the hot glue.

LargePaperCup (author)Agurri2009-07-21

try filling the brick with speakers with hot glue, let it dry and file the edges of the back pl8 and then super glue it

pryrofreak119 (author)2009-05-24

i use plyers to get that stuff out you just stick one of the tips inside the hole squeeze and twist and the excess plastic i use a file

Big_buck_hunter (author)2009-04-26

Hey when u ordered the sampels were they free thanks

AzraelUK (author)2009-04-07

The iPod connector does give you line out, much the same as the headphone jack. That'd make for a device more similar to the one your sister was after.

minimas1323 (author)2009-03-11

nvm it just worked for me. thanks

minimas1323 (author)2009-03-11

when i clicked a request for a sample speaker it said that there was an error

Agurri (author)minimas13232009-03-11

Err, sorry, I can't help you there.... I ordered 3-4 times from this compagny without any problem... Just fill out the form correctly ... and well.. it worked for me :S.

poi_pai (author)2008-07-19

Forgive me, I'm about as techno-savvy ar a jug of milk. Is there a difference between the speakers you used and the ones inside the earbud headphones, and if yes, what is it?

Agurri (author)poi_pai2008-07-19

Well... the short answer is no. You could do the project with the earbuds, and it's actually a pretty good idea. The long answer is kinda. When I did my project, I wanted something I could check the specs online ( size, power, etc.) I choose my speakers mostly because their size was small (15mm diameter) and power (1w). Oh, and they were also free :).

poi_pai (author)Agurri2008-07-19

I guess my reason for asking is I'm just wondering if the sound was good, or if it was quiet and on the tinny side.

Agurri (author)poi_pai2008-07-20

I have to admit that I was really surprised by the sound level. I think it's louder than the earbuds but hey... don't expect some audiophile quality with the speakers I used... :P

wangtrevor (author)Agurri2009-02-26

how loud would the sound be the sound of mosqutios next to your ear? earbuds 3 inches away from your ear with full volume me at l

Agurri (author)wangtrevor2009-02-28

With the iPod standing in front of me, about 6 inches from me, I would say my Lego Speakers are ~1.5x-2.0x louder than the earbud, both at maximum sound. I guess I could try to make a video to show you how it sounds.

tba469 (author)Agurri2008-11-11

I liked this project, so I got some samples. Just finished trying it out, and I have to admit, I was a little disappointed in the volume of the speakers. I knew I wasn't about to get anything too great, but in a quiet room, I could still barely hear them. I'm going to try again, but with some headphone speakers that are about twice the size. Thanks!

Ja2Pc (author)Agurri2008-12-26

Hey I know how to increase the volume, if you have an iPod go to your iTunes playlist and select all the songa, then right click and select "GET INFO" then a box will pop up, in the box select the option box and in there, there should be a volume increaser it is defult set to 0% so boost it up top 100%, sync your ipod and TADA!!! Hope that helped, visit my website

wangtrevor (author)2009-02-26

can u use a soder for this step?

Agurri (author)wangtrevor2009-02-27

As I explained in Step 2, I used a Dremel tool. Using this method, I could remove chunks of plastics, instead or burning plastic with the soldering iron.

wangtrevor (author)2009-02-26

how do you get the sample speakers?

Agurri (author)wangtrevor2009-02-27

Clicking on the link provided in Step 1, you just ask for a quote sample from the compagny. Free of charge.

Kyda (author)2009-01-10

Like poi_pai said though, if i were to use earbud speakers, would the sound be the same as regular earbuds in a differen visible form or would it be, well, loud?

Agurri (author)Kyda2009-01-10

Well... the sound would be the same...

wangtrevor (author)Agurri2009-02-26

how did u get it free fake aplication? could you help me email me a t (btw u have a very good mind thinking of how to make this )

wangtrevor (author)2009-02-26

where do u get the speakers?

pshinoright (author)2009-01-25

Ay if u want something a little louder try making these outa some of the bigger "duplo" legos. Then you would have more room for bigger speakers. xP cool idea

Agurri (author)2008-12-22

Hey, I already had the wires and I had them for a while... so I don't really know where I got them. But, if you need some good wires and quick, take some telephone cord and rip it apart. They have 2 cables inside and they work great.

dz0004455 (author)2008-11-27

very nice, looks good, bet is sounds good too!!

diyluke (author)2008-11-13

A very nice idea. This would go great with a lego ipod dock!!

loulou92 (author)2008-09-08

just ordered the speakers, hope they're able to deliver to Ireland!! will definitely try this soon!

Vio (author)loulou922008-10-15

Hi, did they arrive? did you have to pay some kind of customs duty?

loulou92 (author)Vio2008-10-30

nope, its been i don't know how long, they never came! it could be due company name i used, seeing as i made it up! also, irish addresses seem to confuse most online forms (no postcode etc!).

Agurri (author)loulou922008-09-08

Nice to hear, and thanks for trying this out. Ask if you need some help.

CarStalkerZ (author)Agurri2008-10-16

i ordered mine but they never arrived

Agurri (author)CarStalkerZ2008-10-16

Well.... it took about 2 weeks for me to get sample. Every time I ordered a sample from this company, it took about 2 weeks.

Austin0lsen (author)2008-09-24

i cant figure out how to get the 2 speakers. when i request the item it doesnt show up in basket do i need an account on the websit?
