Re: ceramic capacitors

Hi,
When did you buy it?, I haven't supplied fusible resistors for a couple of years now. It's a 300mA polyfuse, if you email me your address I can post one out to you.

Re: PCB Assembly Discussion

The resistor is to prevent the capacitors damaging the driver transistor if mechanical shock causes a momentary short in one of the tubes so should be fitted in series with them.

Re: Help! Problem....

It would be just the floating section itself and I'd be happy to repair it though it would be next month before I am back to being able to.

Re: occasional blanking

Red will be undervoltage, I was a bit too cautious with the safety features and almost anything out of spec will shut down the coil driver and supply to the floating section.

Re: Help! Problem....

Have you tried powering off for a couple of hours then trying again?. It sounds like the processor in the clock module isn't resetting and starting up correctly when powered. Beyond that it's probably a fault in the clock section.

Re: occasional blanking

It could be overtemperature, it uses the onboard PIC sensor and is set to be quite cautious - anything that might be considered higher than average will cause a shutdown. I have one here that is behaving the same way though so will investigate.

Re: pcb problem

It's possible it has just been put into sleep mode by the IR sensor, you'll need to put the heatshrink sleeving over D1 and try changing modes to wake it up.

Did you leave the USB power supply connected but switched off when you resoldered the LEDs?.

Re: ceramic capacitors

Hi,
That is the polyfuse, not a capacitor. Best to read through all the assembly instructions first to see where it's used.

Re: Anti static bag parts

Yes, I've slipped up while packing it and that's a button clock kit bag. Could you send me your addres by pm and I'll send out the correct bag.

Re: Some questions about the power supply unit

No, it depends on the battery backup to retain settings. Are you sure the cells in the battery pack are connected OK - sometimes they can stick slightly in the holder and this prevents the spring from pushing them against the end terminal.
