It’s been many months since the T-Mobile G1 was initially rooted. In that time, the process has been streamlined and tools have been built to make it much easier. Having a rooted phone has become even more desirable with the recent release of the 1.5 firmware that includes an onscreen keyboard along with other improvements. Having a rooted phone means you can do tricks like setting up a 3G/WiFi bridge. [Taylor Wimberly] has written a guide to help you easily root your G1 without having to go digging through forums for software bits. The process starts by using [Mike Moussa]’s rooting app to revert the phone to the RC29 build. You then use the “Android stupidly executes everything you type” exploit to launch telnetd and upgrade the bootloader. After that, the upgrade process is fairly easy. You just flash a new baseband and build. Once you’ve got your new custom firmware, you can do future updates using an app from the Android Market. We recently updated our Android Dev Phone 1 to 1.5 and haven’t had any issues.
We wouldn’t want to let a week slip by without something new being made to twitter would we? This time it is a toilet. Don’t worry, they are sparing us the graphic details, it pretty much tweets every time it is flushed. As you can see in the picture above, they’re using an Arduino for the toilet/PC connection. If you really want to make something twitter, this might be a good starting point. It’s basically twittering every time a button is pushed. You can download the source code on the site as well as find a tutorial on Arduino basics.
This weather monitor can track pressure, temperature, and humidity and last several months on a pack of AA batteries. It has a PIC18f452 to control all the bits, as well as some fancy power management to get the most out of the batteries as possible. The screen displays the highest and lowest temperatures of the last 42 hours as well as having options to display all other sensor input, updated every minute or so. You can get the full schematic and parts list on the project site.
