Clock is working, but I have a few problems

by attentiondotnet on Sun Sep 13, 2009 10:58 am

I finished assembling the clock. It is a great kit, the case is really nice. Are the case pieces made on the laser cutter in house, or are they outsourced?

I do seem to have two problems. First, I can power up the clock, and it will work correctly, time is displayed, seconds advancing, but then it will beep, the display will go off, and then come back on, but now the time will start flashing on and off every two seconds. It will continue like this for what seems to be a random time, then beep again and restart the process.

The other problem is that I cannot change the brightness. I press the menu button until I get to 'set brite', then I press the set key, and it displays the current value, but when I press the + key the display goes off and the clock resets, while the brightness remains at the same level.

I have gone through the assembly instructions and checked for anything obvious, like bridged connections, caps or diodes in backwards, etc. but everything looks ok. Does anyone have any idea what I did wrong?

Thanks :D

Post a picture of the board, both sides, as clear as possible.

it sounds like the WDT is kicking in and resetting it. does it loop like this forever or just once in a while? what power supply are you using?

It is pretty consistent, the times seem random, sometimes a few seconds, and I think the longest time is around 45 seconds. I am using the power supply that came with the kit.

posting a photo will help in case its a mixup part (which it could be!)

Found my goof up. I was completely missing the C10 cap. It was stuck under something in the box and I was looking so hard for something wrong that I missed that it wasn't there. I put it in and everything is working great. Thanks for your help!

that would do it! we thought it was something in that area which would cause it to reset. good to see it was fixed!
