Re: Ice Tube Clock - No Beep
Thanks. I still think this is a Q3 issue. Not sure why the replacement didn't work. I'm checking with some of the other engineers to see if we can get to the bottom of this.

Re: Ice Tube Clock - No Beep
OK. A couple more of these have turned up with the same symptoms. We'd like to get our hands on one to see if we can figure out what is going on. Would you be willing to send yours in for analysis?

Re: Ice Tube Clock - No Beep
We are still waiting for the clock. Does anyone else have one they are willing to send in?

Re: Ice Tube Clock - No Beep
I am very happy to send mine in. I am located in Australia.

Re: Ice Tube Clock - No Beep
Ship-times & customs delays to/from Australia can be unpredictable. There were 4-5 other clocks with the same problem. Let's see if we can get any local volunteers first.

Re: Ice Tube Clock - No Beep
I seem to be having a problem that was traced back to this one. A more detailed description is on this thread:

I see there has been no activity on this thread for a few months. I would be willing to send my clock in if this is going to help speed up the process. I am located in the US.

Oops, looks like I was looking at the wrong date when I posted my previous message. Anyway, my offer to send the clock still stands.

@atanas - Thanks for the clock offer. We do want to get to the bottom of this. Please contact [email protected] with a link to this thread for instructions on shipping your clock.

Re: Ice Tube Clock - No Beep
Has my ice clock not been received yet by Adafruit? It took a little while for the box to get to me, but I dropped it in the post about 10 days ago.

Yes, we have received the clock.
Thank you for working with us on this.

Re: Ice Tube Clock - No Beep
The MOSFET ZVP3306 is now in a 'backwards' looking package with the text on the curved side instead of the flat side. the FET must be turned around and solder the other way. If you shipped your kit to adafruit this was repaired and you can email support@adafruit to get it back.
instructions will be updated shortly, thanks!

Re: Ice Tube Clock - No Beep
I did also have problems with non working display segments of the Ice Tube.
It seems to be that there are some spikes coming from the microprocessor, corrupting the timing sequence of the display driver chip.
This problem is simlpy solved by placing some 1000 pF capacitors from the clock and data driver lines to earth. See the picture. Adding these capacitors in this way solved the problem completedly.
Also the most right digit of the display was less bright than the others. This can be solved by adding another 22 Ohm resistor parrallel to the other (see picture). Also the zvp3306 should be replaced by another FET a ZVP2110. The characteristics of this FET suits better the voltages of the circuit.
After all these modifications my Ice Tube is working fine now for some weeks without any problem.
I hope anyone else can make use of these suggestions.
