I'm selling an iPhone/iPod/iPad stand design!

I recently received a copy of Alibre Design Expert 2011 (it's an early Christmas gift from my mom). It's the Educational version, so instead of $1400 it was $200. That's not bad for a CAD package with a license I can use on 3 PCs without needing it to renew it every few years.

So, trying to find a use for this, I decided to make an iPhone/iPod/iPad stand using the sheet metal designing tool (only available in the Expert version, I think).

Since I haven't found a way to export my design as a DXF, I have been unable to make this out of metal (or wood—I'll probably prototype it in wood or on my Makerbot). So, lacking this functionality, I exported it as an STL, scaled it up, and posted it on Ponoko for $1.99 (I think it's a fair price for a few hours work and a nicely-designed stand). You can buy it and then print it on a MakerBot or other 3D-printer. However, it's around 12cm tall, so this will push your machine. If you're outrageously wealthy, you can have Ponoko make it for you, but I dont think it's worth it.

At some point I'll get Alibre to output to DXF so I can allow people to make this out of sheet metal, wood, sheet plastic, and other flat-but-bendable materials. That would be better worth the $1.99.

Don't give me grief on the license—it's more than likely I'll change it to something more open. Right now, I'm just playing it safe.

TVKiller: An iPhone App to Act as a TV-B-Gone

I am currently making this app as a TV-B-Gone-like device: all you do is push the button and all the TVs you're facing turn off. The concept is simple: push the button, it maxes out the volume and plays a recorded file of all the TV off-codes, the IR LEDs transmit the signal from the audio port, and all the TVs go off.

Feel free to fork the Git repository to debug it (at the time of this post it has 10 errors and 6 warnings). As I'm new to Objective-C, I need all the help I can get. The project is under the GNU GPL, currently. I'll figure out the licensing stuff later when the project actually contains the recorded codes from a TV-B-Gone; the current "codes.mp3" is just a 440 Hz square wave for testing. That will be replaced by the real "codes.mp3" when it becomes available.

If you have a TV-B-Gone, the means to record its codes as a WAV or MP3 file, and want to help with the project, I'd appreciate it if you'd record its codes and then send them my way so they can be integrated into the project (whoever does so will be credited properly).

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.

WordPress 2.0 for iPhone is here!

Ok, so I just got the WordPress 2.0 app for my iPod touch. It's awesome. I'm actually posting from it right now! I was surprised that it could work with self-hosted WP, but it's true. I'm glad. :)
