Daqq made a really simple The AVR controlled clock, source and schematic included -
A friend of mine needed a clock into his amplifier as an extra function. So I made him one. It consists only of one AVR processor and one BQ-M512RD (or compatible, with common anodes) LED display.

Want to find out if your favorite author has a book coming out? Use Amazon’s advanced search in the book section to get the scoop.
Not only can you search by author, but you can also refine your search to find specific upcoming books and subjects. For instance, say you wanted to know all the books about cats that were coming out in 2009 - you can do that (and get a jump on the pre-ordering if you really want to).
I could think of about a hundred ways to make a simpler clock, but this Ball Bearing Clock looks fantastic.
Video after the jump.
“I though about building a clock with a pendulum activated by the fall of bearing balls. The first thing to design was the engine which was to sustain the pendulum’s oscillation: how […]

We have been itching to try running an AVR micro on fruit power. I do
have the latest Picopower AVR samples, but it was too much of an
effort to solder a 64 pin TQFP and so we decided to give a try with
Tiny13V chip instead. The chip was setup to operate at an internal
clock of 128KHz with a divide by 8 setting. A program to toggle an LED
on pin 3 of the micro was set up with a series resistance of 4.7KOhm.
The fruit cell was made out of a bare PCB partitioned in 4 sections.
The copper of the PCB made up one electrode and for the other we used
zinc strips from new batteriesTwo lemons cut in half were used.
The setup works well and the LED light didnt seem to diminish at all.
Scott Hanselman of Computer Zen put together a great post on preparing yourself for the unknown.
He’s got a lot of practical tips here,everything from an emergency getaway USB thumbdrive to photographing your serial numbers of your higher dollar stuff; as well as assembling a three-day emergency food supply, figuring out where to meet if your family gets separated, and formalizing a good backup strategy. Got anything else you’d like to add to this list? Thoughts in the comments.
Fighting kids driving you to drink crazy? The always helpful Parent Hacks has come up with an interesting way to make those little rays of sunshine quit their quarreling:
Along their preschool teachers, we came up with “Choice” Day. On their day, the child gets to choose certain things like whether they get dressed first, which way to drive to school and what CD to play in the car (the choices of course depend on the points of conflict!). To keep track of choice day, I made magnets with a picture of each of them. I place that child’s picture on our magnetic white board in the day that is their choice day. If there is any question about whose choice day it is, we consult the board.
Obviously this isn’t a perfect solution, but I think it could really solve a lot of problems. How do you stop the bickering in your house? Let us know in the comments.
