I've done the repair but there's been no change in behaviour: repair.jpg I flipped the board over and checked the resistance between the pin on the chip and the leg of the crystal, and the leg of the crystal and the leg of the capacitor and both values for both sides were nil so I think the connecti...

Well I had a couple of goes at trying to re-solder stuff but no change so I decided to take the components off and start again. I started with the crystal and when that came off it had a collar on one leg: Collar.jpg Initially I thought it was from inside the crystal but having inspected the PCB I'm...

0.74v between ground and 9 and 0.53v between ground and 10.

Negative of pin 9, positive on pin 10 of U2 results in -0.13v

I have my cube mostly assembled but as I was testing the fifth grid the blue LEDs stopped lighting up and the large white ones only light up inconsistently- exactly the same problem as users Cube1 and geekazoide had last year on page 5 and 6 of the thread. Unfortunately the resolution to either case...

Yeah, that makes sense. On the subject of square pads and printing there is something else I'd like to double check. The instructions for the electrolytic capacitors read "When placing the component the silver stripe on the capacitor should be on the black half of the footprint." You can see from th...

I'm building this kit (v1.1) but I've got to a point where the instructions are unclear The large LED instructions say "When placing the LED the shorter negative pin should be positioned to the flat edge on the PCB footprint." LED.jpg I understood the flat edge of the footprint to be the flattened p...
