IPod Laser Pointer


If you thought there wasn’t anything else to shove on the end of your iPod, [Alex] is here to set you straight. He used the DC power that’s available on the iPod’s dock to drive a cheap laser pointer. It’s pretty easy to do – just get a dock connector (sparkfun has em) and add a laser pointer module. If you’d rather access everything else, check out the super dock I put together a while back. Hit the read link if you’d rather see the picture in color.

DIY IPod DAC Modding


Red Wine audio offers the iMod – a service that modifies the DAC in 4th, 5th and 5.5th generation iPods. Despite requiring some fine work, the mod isn’t that difficult. [joneeboi] sent in his DIY DAC mod how-to, and even better, it’s suitable for 3rd gen and 1st gen Nanos. The audio signal is tapped directly after the DAC, and the SMD capacitors in the iPod are replaced with high end Black Gate capacitors. This is just the mod feed the best possible signal to your headphone amp

IPhone GPS Module


The boys over at engadget put this up while I was working it over, but I’m still gonna hit it. [Curt] sent in the iPhone GPS he put together. He’s using a micro-controller to send the ground toggle handshake we mentioned in the iPhone serial tutorial, along with a small NMEA serial GPS module. After the handshake is completed, the controller hands over the serial port to the GPS output. (Since the handshake only needs the ground toggle, I’d guess that the module is connected to the TX/RX lines all the time.) By the way, the GPS looks like this SiRF II board sold by spark fun electronics.

Upgrade Your In-ear Headphones


I’m a fan of my Etymotic er6i (which have mysteriously vanished…) headphones, so this simple hack caught my eye. [James C] sent in this simple method of upgrading the more affordable apple in ear headphones. The idea is simple, use a small hole punch to cut out the center of some cheap foam earplugs. Then replace the soft surrounds on the headphones with them. I’m guessing that this trick would work for quite a few in ear headphones that I’ve seen lately.

Simple IPhone Headphone Mod


Apparently the iPhone jack isn’t quite standard – it’s a bit recessed to the point that third parties are offering adapters for it. [John] offers this simple method for modding Etymotic’s fine ER6i headphones. (If only I could find mine. I haven’t seen them for 8 months.) I suggest using a utility knife over a pocket knife. It’s simple, easy, and will probably work on most headphones.
