LED Cube 8x8x8

Step 30: Build the controller: layout

We took out the biggest type of PCB we had available (9x15cm) and started experimenting with different board layouts. It soon became clear that cramming all the components onto one board wasn't a good solution. Instead we decided to separate the latch array and power supply part of the circuit and place it on a separate board. A ribbon cable transfers data lines between the two boards.

Choosing two separate boards was a good decision. The latch array took up almost all the space of the circuit board. There wouldn't have been much space for the micro controller and other parts.

You may not have the exact same circuit boards as we do, or may want to arrange your components in a different way. Try to place all the components on your circuit board to see which layout best fits your circuit board.

Sorry to add to the list of people wanting schematics, but could you please send the schematic files to [e-mail]? minor hitch while trying to download it. Also, I need to say great job, I love this project.

[CarlK58]

I was able to download the multiplexer_board.sch but none of the others. Could you please email the files? This is one awesome project, it is perfect for teaching digital concepts. Thanks for sharing your work and for your time. My email is: [e-mail]

Hello everyone. Just in case you were wondering / having trouble, the .sch files (that are downloaded with a .tmp suffix) can be opened in Eagle Cad (do a Google search). When you first download the files, make sure to change their .tmp endings to .sch!

I've been thinking how you can use a 16 pin connector, and as little use of wires. This is a preliminary layout of my idea. Not all do, but it seems to me to capture beautiful

[hottpunkrockdude]

can you send me the .sch files please. It only comes up as a .tmp file when i try to download them. [e-mail] Thanx in advance

How do you know where the 1k ohm resistors go, compared to the 100ohm resistors on this schematic?

[jasongobus]

Hi could you also send me the SCH file too.. :)
it wont download for me either
Cheers

Hello can you send the files multiplexer_board.sch and avr_board.sch to [e-mail] because i can't download them.
By the way nice cube.

[POMAHbl4]

Hi, i can't download this files. Who can send it to my e-mail: [e-mail] .Thanks

[TechNotes]

I will. The files are coming to you. :)

[suhaaspai]

ur led cube project 8x8x8 is awesome

i too want to make it

can u please send me the codes using shift registers,atmega 32

send me at [e-mail]

[matiRLC]

Hi, can you send me the files too? [e-mail] .
Thanks!

[TechNotes]

Sure thing!

[scinutz]

Sorry to bother you, but could you send those files to me also??? I can't download them either. Thanks. [e-mail]

[Alejandro91aris]

[manchopi]

Hey I was hoping you can send the files to me to [e-mail] plzzz thxs

[TechNotes]

I hope everyone realizes that you can download these files from this Instructable.

@manchopi It's sent.

[JavierCadillo]

Can u send me the files: [e-mail], thanks in advance.

[ares619]

same here, I really want to do this as a project. :) my mail is: [e-mail] thanks in advance

[Bardaky]

same with me, i tried to open the files with eagle, but i just got some strange text
can you please send me the files? my mail ist [e-mail]
thanks in advance

[TechNotes]

@Bardaky: You have to change the extension to .sch or whatever file it's supposed to be

[Bardaky]

thats what i found out just one hour after my first comment :D but thanks for the answer

[haizun]

Hello techNotes,

I know this thread has been too long ago. I wonder if you could send me the code? my email is [e-mail]. Many thanx!

[jeypeg27]

hey technotes,

thank you very much!
can you send the code to my e-mail?
[e-mail]

thanks! thanks! thanks!

My PCB's have just arrived. Since I have some PCB's spare, drop me a note if you are interested. Photo's are attached, some compontents are still missing on the photo.
It are two printed circuits, 10 x 8cm, stackable, real neat.

[r.mulder]

The boards keep refining whilst they remain functional the same. After the green and blue I now have a bunch of orange/red ones. The latest one have the orientation of transistors in both TO18/72 and TO92 housing.

[bdmsoft]

Hi I wold like to have PCB how to get it ..

[r.mulder]

Hi, either send me a DM via this website, or write me an email to roel.mulder at gmail.com and I'll send you the info.

[r.mulder]

As Bruce pointed out, the transistors on the right photo are orientated incorrect, see picture by Bruce below.

[dabamrak]

Ah from you I bought the spare :-). Tnx for the refund on the shippingcosts! Today I received my order from Futurlec and I'm very sattisfied. So now the work starts!

[martin31c]

So, any news on the PCB boards?

[rclayled]

Sent PM re PCBs
