Sprint Airave Teardown

Got my hands on a Sprint Airave (full model number SPDSC26UCS) in the hopes of being able to hack it, but the FPGA ended up being an Altera HardCopy II chip, which is basically an FPGA that is hard-coded to remove the FP (Field Programmable) functionality.

So, not wanting to waste a $40 investment, I decided to take pictures of the insides in the hopes that it will help someone figure out some hacks for it.

If you need more-detailed pictures, let me know and I'll be happy to take them for you. I hope to get some logic analyzing going at some point so I can spoof the GPS data.

DIY Nikon D5100 GPS

Recently, I bought a Nikon D5100. It is the best camera I have ever owned. EVER. You have no idea how happy I am with my purchase of it (and I should be happy with it—at $840, it's nowhere near cheap). One of the awesome features it has is GPS input. It can take TTL serial GPS data and use it to geotag pictures. This is awesome, but it comes with a catch: Nikon's GPS is $250! It's also absurdly bulky. Wanting geotagging that I can easily disable (I don't want home pictures, etc. to be tagged), I built this simple GPS that will work in many of Nikon's newer cameras.

Magellan Maestro 4040 Bootloader?

A bootloader?

Can anyone tell me what this is? It seems to be some sort of bootloader. I looked it up, and it seems as though you can update the WinCE image by using WinCE update. If I can get a backup Magellan Maestro 4040 WinCEimg.bin, I'll see if I can upgrade the OS to a normal WinCE environment, complete with desktop. Maybe in the future I'll be able to get Linux on it. Let me know what you think in the comments.

Power button is select, reset button is a down arrow. Here's the Menu breakdown:

Fun With Git, iPod touches, and Cellular Modules

See my iPod touch Cellular Upgrade to see what I mean. This pretty much turns any iPod touch into an unlocked GSM phone. There's also potential for making it have a cellular dial-up modem, but that is a bit beyond my coding capabilities. At least the hardware would be capable of it so someone who can get it to be used as a cellular modem can just fork my project. I <3 Git.
