iPhone 3G S teardown

iphone

Already, both Rapid repair and ifixit have torn down the new iPhone 3G S, and phonewreck has provided some analysis. The new CPU runs twice as fast at 600 MHz and supports 720p video. They also found that the new 3 megapixel camera took better photos. Surprisingly, despite apple’s claims that the new phone has significantly better battery life, the battery itself has only 6% more capacity. Overall, not much has changed.

Palm Pre teardown

The newly released Palm Pre has been torn down by both Rapid Repair and iFixit. They note the easy to use interface, but the slide out keyboard makes for weird transitions. There’s nothing surprising on the hardware side except capacitive screen and LCD come as a single unit and would have to be replaced together if either fails.

UPDATE: phoneWreck’s analysis

Palm Pre iPod spoofing confirmed

palmpre

The new Palm Pre cellphone has a “media sync” feature which lets the device sync with iTunes in a fashion identical to an iPod. Last week [Jon Lech Johansen] speculated that this was not done in cooperation with Apple and that Palm was spoofing the iPod’s USB controller. This was confirmed today when a tipster sent him a screenshot of what the device reports in both standard and media sync modes. The Palm Pre reports its Product ID as iPod and Vendor ID as Apple with a few other changes. [Jon] notes that it doesn’t change the root USB node, so Apple should be able to block this behavior with an iTunes update. With Palm already pulling tricks like this presumably through software we wonder if this will become a full-on arms race.

Stantum’s high precision multitouch

touch

We love keeping track of new interaction technologies and this new touchscreen by Stantum looks especially promising. Engadget shot a hands-on video with it at the Mobile World Conference. It’s a resistive screen, so it can be used with both fingers and styluses (unlike capacitive screens). It’s sensitive enough that you could use a brush too. The screen supports any number of multitouch points and does pressure sensing based on the size of the detected fingertip. The touch detection is actually more accurate than the screen can display. Stantum is hoping mobile manufactures will pick up their input framework for inclusion in new devices. The resistive touchscreen was built to Stantum’s specifications (it won’t work with current phones), but they say it wouldn’t be hard to go into mass production.

Cell phone triggered fireworks

remote_trigger

[Mr. Hasselhoff] is using a disposable cell phone to trigger his fireworks. He has wired into the speaker leads for the speaker phone. When the phone rings, the current sets off a thyristor allowing for a battery pack to be discharged into a rocket fuse. These fuses heat up and ignite, so you can use them to light fireworks fuses pretty easily. This is pretty simple and cheap, considering the price of the cell phone was only $10. His next idea was to have it recognize dial tones and set individual fuses off, but that would require a microcontroller and a much more complex hack. At that point, you might as well just build a fully fledged wireless fireworks launching system and possibly add rocket launching abilities too.

iPhone 3G unlock released

As promised, the iphone-dev team has released yellowsn0w. You can install/uninstall via Cydia. It works fine with the latest firmware too. This sentence is filler.

Hackit: What did you get?

adp1

It’s the season of gift giving. Did you get anything interesting/hackable? What will you work on next?

We gave ourselves an Android Dev Phone 1 (ADP1). We hadn’t really considered getting a G1 until the ADP1 was announced… It’s actually a lot of fun to use as our primary phone. Our favorite app so far is connectbot, the SSH client. The interface is really smart, way better than all of the iPhone clients.

What did you get?
