Would this have anything to do with the wire attached to the top layer - maybe I haven't soldered it properly? Yes this is the most likeliest cause of the problem. That wire is responsible for supplying power to the entire top layer of LEDs. So unless you have every LED on the top layer the wrong w...

I have replied to your original post on our blog site but for convenience i'll post it here: There’s nothing particularly special about those two layers and the fact that the other to layers are working helps rule out a lot of possibilities so hopefully its something minor. By not working do you m...

Thanks for the feedback

I assume the cube is running the default demo that's preloaded into the chip ok? If so this helps rule out some possibilities. Assuming it is running the demo there are four things that come to mind: Firstly under 'Tools' menu in the Arduino IDE do you have 'Arduino Nano' selected as the board type ...

There are a few pieces of software available that are designed for converting bitmaps to byte arrays specifically for use with monochrome LCDs. However you need to that will convert the pixels of the bitmap to an array in the correct order. For the HCuOLED library this needs to be a 1 dimensional ar...

I've just added an FAQ to the first post that will give you more information on how to set up the sensor. This includes a suggestion on how to set it up to get the maximum range. Under normal conditions you should defiantly be getting a much greater distance than 1 inch.

I did ask one eBay supplier (I forget who) a while b ack and he assured me that it would work. We've not had any success in finding a fix so unless the eBay seller knows something we don't I think it may be a case of misinformation. So now I have two that are useless at the moment. If it's no use t...

I'm afraid the K150 doesn't currently work with Windows 10. I've added a comment to the FAQ in the first post about this but I'll paste a copy of this below: Currently the K150 does not work with Windows versions above Windows 7. This is due to the fact the latest versions of the Prolific USB driver...

I've installed the Linux version and managed to replicate the issue. It a permissions problem and so Quartus doesn't have access to the programmer. You can resolve this by creating a udev rules file: First you need to get the product ID of the programmer. In a terminal window issue the following com...

Without the fan attached, the voltage is 16V, but when connecting the fan, it drops to a little over 2V.

In both cases where are you measuring the voltage? Also, on the module do you see an LED illuminated when the fan is connected?
