What's the matter?  You can't find people willing to work for $5/day in your neck of the woods?

Fantastic job on the clock.  You had to do quite a bit of engineering on the display and the interface.  Your sister had to be stunned by this clock.  I really like the IDE cable!

Which IC?

A lot of those small motors are 3vdc.  The motor still spins freely or is it seized up?  Without specs on the motor there's no telling.  Pictures?  Interesting that the motor driver chip got red hot without failing.

I was pretty excited too.  Awesome to be able to buy those boards and chips for so cheap vs. Arduino.

You should be proud of your project - very impressive work!  You ought to make an instructable for it at instructables.com.  What is your source for the LCD screen and how much did it cost?

Any video of it in action?  I would like to see your code - I just wrote code for a digital clock using LED's.  Looks like a pretty slick project so far - very clean.

Riley had it right.  Each row of LED's have common cathode, each column of LED's have common anodes.  To light an LED up, you set the row LOW and the column HIGH.  The only drawback to this method is you can only control one LED at a time.  Even though there may be 42 LED's lit to make the clock read 12:58, it's persistence of vision and fast switching that gives a steady, flicker free display.  I estimate the refresh rate of the clock display is around 300-400 fps.

Did you know you can use a program called Energia to program a TI Launchpad with Arduino sketches?

I built the Lite Brite clock and made an Instructable out of it.  It's currently on their front page.

Maybe try something else?  Like gardening or something?  Maybe programming and electronics just isn't your thing.

Do you ever visit http://www.instructables.com. ?  You may find some ideas there.

Unaclocker-

That dishwasher hack was awesome.  We had a Maytag with that exact same front panel and it went out in the exact same fashion after only 4 years.  I took it apart and took the panel off and tried to find a new one, but decided the part was too expensive, and I wasn't 100 percent sure it would fix it anyway.  So I put mine on the street and bought a new one.  Too bad,  that dishwasher cleaned the dishes really well. 

I'm sure Maytag knows about that horrible design flaw- I won't be buying anything from them again.

My wife and I both enjoyed your dishwasher hack post immensely.

If this were mine, I would move everything to a different server in a different datacenter, maybe even in a different country.  Or at least have someone new take a look at what is going on.  This is one of my favorite forums and also one of the slowest forums Ive ever been to.
30  Community / Website and Forum / Larger nav buttons in forum? on: February 07, 2012, 06:42:21 pm
It would be nice to have larger page navigation button in the forums.  A big NEXT hyperlink would suffice.  I find it difficult to click on the page numbers when I am using my tablet or phone to browse.  99 percent of the time I just want to go to the next page, but I have to clcik on a 3pt sized number.  Requires a lot of zooming in and out.

Alternatively, I suppose I could have my finger sharpened.
