Tell us about yourself!
I made some ne of these following Ben Eater on YouTube with a few changes to the layout to simplify programming. I’m working on a few simple programs but would be interested if you have any to share.
HiI’ve just posted a link to the electronics schematic above. I used Seeedstudio to fabricate the board and Farnell for the components. Other items like the pliers, LEDs and framing wire I found on eBay. The wood for the jigs I picked up at B&Q. Plus you’ll need a decent soldering station, solder etc, ebays your friend here as well. There’s a lot more detailed pictures of sections of the PCB in the word document I linked to in the instructions on how to populate the board plus a few other photos available in the write up of the PCB layout - but it is a bit complex. Good luck with your build. James
I used the same schematic as published on Kevin Daraghs website to be found here > http://www.kevindarrah.com/download/8x8x8/Cube_sch_3_16_13.pdfGood luck with the build. James
Hi LuxxalIf you mean the flat nose pliers I used to bend the LEDs then the width is about 5mm, You can get them very cheap from eBay - example link belowhttp://www.ebay.co.uk/itm/Jewellery-Making-Pliers-Wire-Cutters-Round-Chain-Flat-Needle-Bent-Nose-etc-/292057860364?var=&hash=item440001490c:m:m_7rhXq8HbfhmxHBwxEM3nw
I don't have anymore boards available at the moment. I had 5 made, sold one and I've just finished building my fourth 8x8x8 RGB cube (it gets a bit addictive :-)). Be interesting to know if there is anyone who has built more than one of these let alone 4.I still need to work on my next PCB revision. I'll post a message on here when/if these become available.The idea for the 16x16x16 cube is to use four 8x8x8 PCBs tiled together. - a single PCB to support a 16^3 cube would just be too big.
I don't have any more boards available currently.I am working on a revised PCB design which will make the board smaller (to support a 16^3 cube) and use SMD components but I am still a long way from finalizing this design and sending it out for manufacture.I'll post a comment on here when this revised design is available, probably with all the components already fitted and tested but this'll probably not be in time for your school projectJames
So far we have prepared 2000 of the 4096 LEDs required for a 16^3 cube. I am planning to redesign my current PCB so that I can tile four PCBs together to support this bigger design - I need to reduce every side of the board by 15mm to support this and I am exploring going with SMD components too.This project will take us a long time to complete - the hardware alone is a challenge and then we'll need to rework and upgrade the Arduino driver and code.
There is an earlier question and feeback below on exactly this topic
