For those wanting to do some hacking or kernel debugging on their G1, [macpoddotnet] shows how to make a serial to USB cable. He gathered enough information on the Android platform google group to be able to piece something together. He’s using a USB 2.8V serial TTL level converter, and lists several available that should work. Looks like a pretty easy build.
[Mike] sent in this project. It’s a robot, designed to print on wooden coins while people watch. It was built to be in the iHobby Expo 08 in Chicago. The main movement is controlled by a BASIC Stamp2, while the ink jet system is run off of a Propeller. The entire system has 4 servos, 3 stepper motors, a DC motor, a hacked breast pump, an ink jet head, and 5 IR sensors. in case you missed that, it has a breast pump. We’re assuming that’s the part that picks up the wooden nickels with suction. He states that the project was meant to be entertaining, so there are lots of superfluous and inefficient actions as you can see in the video after the break. Great job [Mike].

Using an IR keyboard is now possible with a non jailbroken iPhone. The folks at perceptive development have developed a custom interface that connects through the headphone jack. They had already developed the serial modem, so this was just another step at connecting peripherals. With some smart and small packaging, this could be a nice attachment to keep around. You can see a video of it in action after the break.
