Step 6: Assembling the Device

Assembling is just a matter of soldering everything together and screwing together the enclosure. The interface enclosure, which is just an enclosure from Radio Shack, needs some small modifications. The enclosure was made out of a potting box that I cut holes in the screen and buttons. 
<p>You are a life saver...<br>i just want to know that will this work for iPhone 4 and does it matter which iOS is being used?</p>
<p>provided that the phone is jailbroken</p>
has anyone tested it with the ipod touch 2g
It's great to see that you can still connect something to an iPod without Apple license crap. I know this works for older iPods, but has anybody had success with an iPhone or an iPod touch? Which generation?
Well I finally finished recreating a variation of your project. I used a pod breakout mini because it has a backshell and all of the pins necessary. For the cable I used an old 24 AWG DVI cable which works great because it is shielded and has twisted pairs for audio out and serial. For an enclosure I used a 6x4x2 enclosure from Radioshack. It was the perfect size for everything. Rather than milling or etching a board I just used countersunk screws and risers for my Uno. For the discreet components I just used a prototype board with power rails I found at work and cut it to size. I also installed an On/Off switch because the AUX cable was putting ignition noise on the speakers &nbsp;which got annoying and it was easier than unplugging the cigarette lighter every time I wasn't using it. Thanks for posting this, it was a lot of fun to make!<br> <br> Pod Breakout Mini:&nbsp;<a href="https://www.sparkfun.com/products/10645" rel="nofollow">https://www.sparkfun.com/products/10645</a><br> <br> Enclosure:&nbsp;<a href="http://www.radioshack.com/product/index.jsp?productId=2062283" rel="nofollow">http://www.radioshack.com/product/index.jsp?productId=2062283</a>
Can you please describe how all of this goes together? Your schematics aren't very intuitive. I'm trying to build this and I have no idea where everything is supposed to go. Thanks, and I'm really excited for this project!
Hi. Sorry about the confusion. I've added some annotations to the schematics that hopefully clear things up. If not, let me know. I think I'll throw together a Fritzing drawing if I get a chance.
Thanks a lot, and if you could do a fritzing drawing then I would be eternally in your debt.
Did you mean pine 12 and 13?
Where are you referring to?
I'm sorry, I meant pins 12 and 13 when you mention 18 and 19.
Wow this is just awesome, i will consider make one. Does it is difficult to build? considering i'm very new to electronics?
Thanks! Sorry for such a late response, but I would say it's a moderate level of difficulty especially if you're new to electronics. But if you want to give it a try I'd be more than than happy to point you towards some resources and help you get the project underway.
Awesome instructable, the final project looks almost store bought, you did a convincing build! Do you think you'll ever incorporate Bluetooth into the screen? I'd pay good money for something like that.
Thank you! I'm not sure if I will, but it would be a great way to reduce the amount of wires.
very nice now if you could put the controls in the wheel and install a hud projector for the screen. might try this in my next car not much point in my current car seeing as how im not taking it with me when i move
I was considering both of those but I couldn't think of an elegant way to incorporate controls into the steering wheel without more wires nor could I think of a way to have a HUD type display that worked in all lighting conditions. If you end up trying something like that please let me know!
This is great - Do you know if it will work with the Podcasting App?
Not had chance to read it yet but how easy would it be to add two extra buttons? Vol Up and Vol Down? <br> <br>If you could do that and make it a bit smaller I'm sure you could make $$ / &Acirc;&pound;&Acirc;&pound; making this for bikers. <br> <br>As a biker this looks way better than other solutions I've tried, the wireless ones are flaky and the wired ones don't take thick gloved fingers in to consideration. <br> <br>Well done mate,
Hello and thanks! I don't see any issues with physically adding the buttons, however, from a software point of view I don't believe it's possible. If you take a look at the Apple Accessory Protocol Mode 4 (the mode required to get data from the iPod) there is not a command for adjusting the volume. My original plan was to have volume control buttons, but as I got further along in development i found that there wasn't a way to do this. I suspect the reason for this is that Apple designed this mode to be used with dock-type devices that had their own source of volume control. Volume seems to set at a certain level and for a car that's not a problem since the volume can be controlled by the radio's volume. It may be possible to build an external circuit to control the volume for the purpose you're suggesting.
Thank you very much for the replies, and sorry for the late response. <br> <br>I will see if I can bribe a friends dad to knock one of these up for me <br> <br>: )
Or, instead of trying to use the accessory port, you could use the headset port to control the volume, similar to how 3-button headphones do it.
Instead of having push buttons for volume control, you could use a rotary switch like what was used on old radios. All it is is a POT. That would eliminate the need for a complex circuit. Just leave the iPod on max and let the POT do the work.
Any idea if this would work with an iPhone 4S running iOS5?
I only have an iPhone 3G with iOS5 and it works with it, so I wouldn't see why not. I'm not making any promises though.
I've just tested the simple remote mode with buttons on my bread board. Worked great. Next test will be to see if it works running the ATMega at 8Mhz on the internal clock.
Fantastic! It will work &quot;as is&quot; with iPhones too (3GS, 4 , 4S)?
I built something similar using David Findlay's Arduino library. I didn't use the screen as you did, but instead I went with the Wii Nunchuk controller so that I could just change songs and artists on the fly. It worked out great until I got a new car and didn't have any easily accessible space to install the control box.<br> <br> <a href="http://www.ryanpourcillie.com/projects/car-stereo-ipod-control-system/" rel="nofollow">http://www.ryanpourcillie.com/projects/car-stereo-ipod-control-system/</a>
Very nice. What did this cost to build?
Thanks! I must apologize, but I don't have an exact number. The only substantial purchases I really made, however, were the LCD Screen (~$30), the Arduino Pro Mini (~$20), and the PodBreakout (~$15). The rest is just some cheap electronic components like resistors and buttons.
Awesome instructible, but its location in some states would get you a ticket. Beware of where you mount it.
Thanks. I appreciate the concern. I'm in Georgia and as far as I can tell there aren't any laws restricting the placement of windshield mounted devices. Safety, of course, is a priority and that's actually why I placed in that corner. It may not be evident from the picture, but I've found that in this particular vehicle placing this in that location provides the least amount of visual obstruction.
What a great idea, my daughter would love one of these, so I am not sure I like it or not, as I am the one who has to build it for her. <br>But you have done a great job with clear instructions and when I am finished I will post a pic to show you. <br>Keep up the good work
Gonna build something like this.... need it for mah car as well! :)
Excellent! If you do please post some pictures of how it comes out!
It looks cool , first time i wanted to chenge my andoid for an ipod, Good Job
Thank you. I'm glad you like it!
