^^This is correct^^. I removed U3, the 10mm LEDs came on the first time I plugged it in, for a short period, alas, when I plugged it in and out again.... nothing. Couple of things to note, I had to place two smaller LEDs in two of the feet, as only two came in the kit, don't think it should make a difference, just giving a full picture. When I tap the pin circled on U2, the feet light up, and stay lighting.andrew wrote:
I take it that not even the 10mm LEDs are lighting up now either?

That pin controls a transistor which switches the base LEDs on and off so that makes sense. It also tells me that either there is a bad connection on that pin, or far more likely, the microcontroller isn't controlling the state of the LEDs because it's not running. If the the microcontroller isn't running then nothing would work and it would also make sense that the base LEDs would randomly turn on or off.When I tap the pin circled on U2, the feet light up, and stay lighting.
I think the next thing you need to do is to check the soldering of all the pins on U2 and components associated with it - R1, C2, C4, C13, C14, & X1. Check for pads missing solder, dry joins, and additionally for U2 that none of the pins of its IC socket have bent under the socket and not gone though the pads hole.
Sorry about that. If you could send an email about this to sales (at) hobbycomponents.com with your order number we'll sort it our for you.I had to place two smaller LEDs in two of the feet, as only two came in the kit

No worries mate, wasn't a dig just letting you know. I have checked all of those connections, all check out. I got a multimeter, is there anything I can check with that that might help?andrew wrote: Sorry about that.
Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)
No a problem, if they were missing from the kit wecan replace them but probably best wait to see if we can get to the bottom of why your cube isn't working first.No worries mate, wasn't a dig just letting you know.

I got a multimeter, is there anything I can check with that that might help?
Negative lead on U2 pin 8 and positive lead on U2 pin 7
Negative lead on U2 pin 22 and positive lead on U2 pin 20
Negative lead on U2 pin 8 and positive lead on U2 pin 9
Negative lead on U2 pin 8 and positive lead on U2 pin 10
Can you tell me what voltage you read for each of the 4 measurements above. If you need help in identifying the correct pins just let me know.

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)
We actually bought a second kit and rebuilt it, as we need to finish for next week and do some programming on it ourselves for a team project in software development degree we are undertaking. We got the second cube built and functioning today, thank you for your help Andrew, I will be back onto you as soon as we finish our exams, to see can we get the first one sorted. Much appreciated.andrew wrote: Yes,that would be helpful.

We are going to try and implement this in a 3d fashion: https://en.wikipedia.org/wiki/Wa-Tor , obviously we will only have one colour, but the pattern should be demonstrated, I'll keep you posted.

Ok, no problemI will be back onto you as soon as we finish our exams, to see can we get the first one sorted.
It looks looks similar to the game of life. It will be very interesting to see your what you manage to create.We are going to try and implement this in a 3d fashion

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)
Hi there, I seem to be having issues with my cube, similar to what Cube1 was having recently.
I've built it all up, but when powered on, the cube doesn't behave as expected. Each power on results in something different. Either the 4 white leds illuminate and nothing else, or nothing illuminates, or the 4 white leds turjn on dimly then eventually a couple of blue leds turn on etc.
I've checked my soldering, and pretty sure it's ok (though there's always the chance I may have missed something).
I completed the voltage checks you asked for with Cube1 a couple of weeks back. I read:
5V between pins 8+7 on U2,
5V between pins 22+20 on U2,
0.7V between pins 8+9 on U2,
0.4V between pins 8+10 on U2.
Also, the two tack switches (mode and reset) don't seem to do anything when pressed. I've checked the connection between the switches and the chip itself, and all seems good. The power supply is rated 9V at 2.0amps.
Any ideas?

I believe you have also contacted us directly and the issue is being dealt with there.

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)
Hi All, well I've finished my cube at last and after a Mod to the LED's it is working great. Please see attached pics. My only problem is that I can't upload. I am using the correct driver on Win 10 and have tried just about everything I can think of, if anyone can help with ideas I would be most grateful

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)
You cube looks great. I can't see anything wrong looking at the error message. I assume that you are using the programming cable supplied with the kit? If so are you aware that you will need to press the reset button on the cube at the exact point the Arduino IDE finishes compiling the sketch and attempts to upload it? This is necessary as the supplied cable doesn't have a DTR line which is normally used to reset the board so that the bootloader can restart. If that's not your issue can you check, and let me know the following:
1) In device manager can you find the entry for the cable and make sure there isn't a yellow caution symbol next to it.
2) In the Arduino IDE under Tools->board you have 'Arduino Nano' selected.
3) If you are using the latest version of the IDE there is an additional option under Tools->Processor. Can you make sure that this is set to 'ATMega328P (Old bootloader)'
4) Can you let me know which coloured wires on the cable are connected to which pins on the cube.
