Hi Andrew, many thanks for the reply, your diagnosis sounds better than mine! I will lift the xtal off the board slightly, check the caps around it again and report back, (will remove the cap I put in) and see if that brings any results, I may well put the cap back even if lifting the xtal solves it...

Hi Andrew, bit of a newsflash post, awake early today and decided to sit at the bench and try and look for clues at the erratic behaviour of the cube, with my limited knowledge, I watched what the cube was doing with each of the power supplies as follows. 1. iPad usb charger in the serial pins gnd a...

Hi Andrew, have some progress, with all the grids out and the chips removed I made sure all the pins had continuity from the ic sockets to the pads on the rear side of the board, they all buzzed out ok, so reinserted the ic’s - and decided to check the grids again, only this time used my bench sup...

Hi Andrew, as promised a report back, and still have issues with erratic led behaviour. Here’s what I have done so far.. Took all the 8 led frames from the board and checked all the leds again, 1,2,3,4,5 and 6 grids were fine, 7 and 8 when tested again, 3 leds on grid 7 and 4 leds on 8 were very d...

@Andrew, how awesome would that be, it does seem however the WS2812B's all seem to be smd’s, after a quick google, just 3 wires would make the design a lot easier I guess, I can’t believe they are not in the pipeline somewhere in the Far East..... Re flow of the board in progress will post any c...

I was being a bit tongue in cheek with regards to the RGB version, it would be a complex build to design and execute, 512 leds with 4 legs I presume, all fully adressable is just mind blowing stuff, I have fully RGB tape and bulb style leds running on my arduino, the make superb Xmas lights that peo...

Many thanks for the reply, I’ll try and borrow a scope and see just how noisy the phone power supplies I am using are and maybe post some screen shots, it is very weird tho, I will touch up the caps and also try the power socket using my bench supply and report back, overall it was a complete succ...

Hi, just completed the cube... and appears to be working fine, well done the designer and team who made it easy to follow when putting together, can I just add a few comments, not criticisms by any means! Would it have been a good idea to include a phone style socket on board when using a standard p...
