Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

SUCCESS Difficult to believe that a) I didn't solder that pin correctly to start with and b) missed that it was a poor joint the first time I checked it. I don't think I am solely to blame though, having identified quite a few LEDs that were passing current in the reverse direction. I must stress t...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Pin 24 has been re-worked and there is now a connection through to pin 2 on U1. I also re-worked pin 25 as that was looking a bit dodgy in the photo as well. I no longer have a reading from pin 2 U1 to ground, so fingers crossed. All I need do now is reassemble the cube and see how things go.

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

I've dismantled the cube matrix, and gone back to double checking each individual LED assembly, due to the resistance reading I was getting. I checked continuity between the anode/cathode, cathode/cathode and anode/anode on each of the 8 assemblies. As I result I have replaced 7 LEDs that were allow...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Hi Andrew I've checked through the suggestions you have made. Sockets for ICs U1 and U3 look good. No solder bridges or dry looking joints. Continuity has been checked from the legs of IC U3 to the actual anode layers, and these are all good. Pin 23 on IC U7 seems OK as does it's resistor. Measureme...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Thanks for the reply Andrew - I will check those shortly and let you know. In the meantime, I have written a very basic piece of code that illuminates one layer of Leds at a time and steps them upwards at one second intervals, and then starts at the bottom again. I find this easier to see what is go...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Having given it some more thought, and trying to explain the 'bouncing' phenomena, it seems logical to assume that when the cube is trying to light the LEDs on the 3rd layer, it's actually lighting the LEDs on the 1st layer. It would explain why the 3rd layer isn't lighting at all and the 'bouncing'...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Well I ordered a 2nd cube, hoping to build it and avoid some of the mistakes I made with the first one. The board itself went together easily enough again, though this time I omitted the line in connection and associated parts. Using the same jig as last time to build the LED rows, this time I pre-b...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

My cube stopped working today, or rather it stopped working properly - some LEDs were lighting up when they shouldn't and I figured it would be easier to build a new one than waste time trying to debug this one. This is especially true given that there are some aspects of the build that I would chan...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Andrew, thank you for taking the time to reply. I have got to the stage now where I am worried that my attempts to upload a sketch to my cube may somehow corrupt it and prevent it working at all, so I have given up trying. To my best recollection from my last attempt, the sketch didn't upload at all...
