I didn't look closely when I mentioned about how to properly use heatsink compound. Was it hot before you added the heatsink? Was it hotter after?
You pondered why the heatsink might make it hotter:- Someone mentioned maybe glue conducting. I mentioned the glue might insulate the heat. Overlapping a couple of components, maybe one didn't like being heated by the other? And, what if the added heatsink is acting as an UNWANTED capacitor between various pieces of the circuit? You didn't join the heatsink to earth/gnd or a rail, it was floating? Gnd-ing pretty well removes the coupling effect. [And the rail is effectively grounded.] John K/ ----- Original Message ----- From: Kiran Otter To: [email protected] Sent: Sunday, March 29, 2015 8:53 AM Subject: [neonixie-l] Re: Need help with a tubehobby clock overheating Niek, Yes, it's showing the seconds in the hour digit, and in the minutes digit.. though not as strongly. If I force it to display the date or number of hours on the tubes, I can see whatever is in the most-right tube, faintly in the next to left tube. And I swear I can see the 6 in the seconds tube coming on for like 4-5 seconds. Again, it's all really faint, so I assume it's not really a problem. Before I swapped the driver chips around, I was getting faint digits in the left most tube. So it does seem to be driver related. But I think it's OK for now. Is there a known good source for the driver chips? Someone on ebay? Kiran -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
