Ice Tube Clock: Digits start to fade until none are lit

by francisco300 on Tue May 21, 2013 9:32 pm

After finishing the kit with all of the tests resulting in how they were supposed to go i plugged in my clock. Everything seemed fine. I set the clock the date and messed with the brightness. At first the leftmost digit was blinking in and out while in settings. After finishing setting it up the leftmost digit kept flickering. Then it completely turned off, then proceeded with parts of the next digit until after about a minute the whole tube no longer displayed any digits. I unplugged the clock and plugged it back in with nothing lighting up. The beep does happen though. I unplugged it and waited about a minute to plug it back in. All of the digits lit up with the leftmost digit flashing and eventually the same thing happened.
Here is a link of one of the digit problem occurring.

I know it has been a year but I was wondering if you guys found a solution or identified the problem?

Yes. The problem appears to be due to a marginal Q3. These are static sensitive devices and easily damaged in handling. If you contact support@adafruit.com with a link to this thread we can send you another Q3.

Some forum members have come up with alternatives to this sensitive part. If you are interested, Russell 27 has a nice write-up on the options here: https://forums.adafruit.com/viewtopic.p ... 83#p258920
