[Huan Truong] was looking for an Internet interface for one of his projects. In this case it’s a temperature logger, but it could be just about anything. He decided to give the Chumby a try, but was turned off by its use of Flash as the app framework. He decided to open up more options by running WebKit via his custom Chumby’s firmware.
In the video after the break he shows the boot sequence and demonstrates his first app. The device runs through a screen calibration as it powers on. When the app comes up it looks and responds much more like an Android or iPhone app than the Chumby interfaces we’re accustomed to. This technique gives you pretty wide range of app development languages. That’s because all the Chumby really cares about is the index.cgi file that serves as the interface. Development and debugging can be done on a desktop (not that it couldn’t before but Flash development under Linux was always a pain).
It looks like this idea isn’t new, but we don’t recall seeing any other projects that used WebKit as an alternative Chumby interface.

Here’s a watering can and water vortex that are controlled with a webkit browser interface. The interface displays a drawing of the watering can on your browser. If you grab one of the handles on the circle around the image and move it, the can will rotate as well.
Okay, so this isn’t going to change the world and actually presents a fairly useless watering setup. But [Ben] seems to be a master of fabrication and that’s what we appreciate in this build. The watering can is solidly mounted and moves fluidly with seemingly little effort from the motor. He uses a spring to keep the rope loop taut, sourcing a castor wheel and automotive power-window motor to provide the motion. The hinged base on which the can sits has a potentiometer in it, used to measure the current position of the watering can. Remember these techniques as they’ll come in handy in your future builds.
There’s also a little bonus at the end of the video after the break. We wondered what [Ben] might use that power drill controller hack for. Looks like it makes an appearance in his water vortex work.

With netbooks being slim and mostly utilitarian, it seems a bit contradictory to use a standard and somewhat bulky web browser with them. After all, we’re trimming down the operating system to perform faster on these little devices, so why not thin out the focal point of the netbook: the browser. Firefox, Chrome, or Safari may be well and great for a full powered desktop or laptop, so how about something a bit more trimmed? Enter the lightweight Webkit based browsers: Arora and Midori.

While working towards open-sourcing Android, the team continued to work on new features in their own private development branch. These have now been published publicly in the “cupcake” branch. There’s a lot of interesting new features and bug fixes included. We’ve got a rundown of many of the significant additions after the break.
