I’ve hacked up the Chumby PhotoFrame source from http://www.discarded-ideas.org/chumby/photoframe by Wansti.

http://github.com/kstephens/chumby_photoframe/tree/master

Fixed a few bugs and created a USB image to enable http://localhost/image/ browsing on the Chumby.

I’m working on an CGI to allow uploading of images directly to the Chumby.

Please give me feedback.

I got a Chumby as a holiday gift; it’s really cool and really hackable.

The good:

• Hardware and software is open-source.
• Runs Linux.
• Very easy to hack: SSH, BusyBox, lighttpd, Ruby, etc.
• Two USB ports.
• Audio out (internal speakers sound amazingly good for their size).
• Built-in microphone (haven’t figured out how to use it).

• Can play FLAC files from USB drive.

The bad:

• It’s very difficult to get it to show pictures off a USB drive. The only way apparently is to install a local HTTP server and use a widget: http://www.discarded-ideas.org/chumby/photoframeusb
• Flash widgets/apps only — Flash is not open-source.
• Switching between widgets and channels is fiddly.
• One button is not enough considering widgets take up the whole screen modally.

• It needs more RAM. 64MB is just barely enough.

Hardware Review

This is a really cool keyboard, except that the ESC and function keys do not light up and are strangely located and difficult to press. I also don’t understand why the spacebar does not light up; seems like it’s the most important key. The construction is not very good and the feel is a bit mushy. However, this keyboard is fun for hacking and could be really great for user training.

Device Driver and Source Code

After much troubleshooting, I have created a simple C driver library for the Luxeed deTA 100/200 keyboard using libusb. This driver allows the LEDs under each key to be set from C from most Unix-like operating systems. This is my first attempt at reverse-engineering the protocol of a USB device.

How to create a deep clone of a DataMapper::Resource object so it can be stored in a different repository.

This does not work:

obj = Foo.first
obj = obj.dup
repository(:other) { obj.save }
