Is That Some Type Of New Kindle?

[Mr C Camacho] picked up an inexpensive digital picture frame hoping to hack into it. He hasn’t had the time to crack open the hardware so that it will do his bidding but he did find a creative way to make it an ebook reader. Using a python script he processes books, creating images of the pages.

The python script, available after the break, takes free books from Project Gutenburg and spits out JPG images. Page turning and bookmarking are not what they ought to be but the process does work. The thought of someone staring at a picture frame on the subway is a bit amusing but we’re sure that sooner or later someone will ask if it’s a new version of the Kindle.

Gentle Wake Up Alarm

[Michiel], unsatisfied by his Phillips wake up light, decided just to make his own. He really wanted programmable weekend alarms as well as an easier to find snooze button. At first, his circuit was not reliable enough, losing several minutes per hour, but he gutted another alarm for the 1Hz crystal. After some carpentry, his final alarm ended up quite nice. ¬†After so many aggressive alarm clocks, it’s nice to see that not everyone needs to be assaulted out of bed.

Correction: apparently, there’s no 1Hz crystal. That was a guess on my part. -[Caleb]

PIC Pong Clock

[Andrew] built this pong clock over the span of a couple of days. The PIC 18f2520 he used can serve as a real time clock with the addition of an external clock crystal. His project proves the usefulness of an oscilloscope as poor board layout caused interference in the crystal connections, something difficult to troubleshoot without this handy lab tool.

Pong clocks have been quite popular. This one is nice because it’s easy to throw together now that [Andrew’s] done the coding work for you. Written in assembly, reading and understanding his code might be a good exercise if your low-level language skills are lacking.
