Ahhhhhhhhh I see! That makes MUCH more sense. I thought it seemed like a really convoluted way to wake the backlight! Very clever, I didn't realise there was that functionality (I haven't read the entire thread. Thanks again, day trippr.

Re: RE selection; is there a specific requirement? Adafruit have a nice 3 pin with built in push button, 24 pulse/segment.

Ha yeah, it was more to check I was on the right track. First thing that came up on Google. I have to get some washers to finalise the case for the hardware, so I can pick one up locally.

Here's a link to a breakout board that makes it a tiny bit easier to connect that. If you don't want that, there's a link on that page to an encoder on Mouser.
Is there a way of ordering just one of each board, or a set of all 4 different boards, instead of 4 of each, or is that just a limitation of pcbs.io?

If you can only buy in 4s...... is there anyone in the UK who would want a set of them?

Those are so tiny I can’t imagine any of the PCB houses would sell a single. No, there’s no way of ordering one of each that I know of - unless you manually panelize and then you’re stuck having 4 of all of them.

OK - I've figured out enough to get myself to the point where I know I don't know enough to keep going, so it's time to seek some guidance.

First off, the amount of work you guys have put into this project is mind boggling. I've been lurking for a while and sifting through everything, and it's an amazing path from the first versions to the latest.

I'm looking at this as a learning project, so I'm generally trying to work out the logic behind everything as I go. I'm working on an Arduino shield (v 1.3.1a), along with the rotary encoder breakout (and eventually the Large Breakout Board) and a parallel LCD. I'm a little stuck - OK, a lot stuck. I'm good with the PCBs and I've got all the resistors and capacitors soldered in. Before I go any further, I want to double check what I'm doing with the remaining parts from the BOM. Can someone confirm the placement of the following items:

2N3906 PNP Transistor - Q1 (seems likely)
SN74HC595N 8-Bit Shift Register - ??
16-pin IC Socket - ??

I'm guessing that the shift register and IC socket go into U1 in the board, but not sure in what order - presumably the socket goes first and is soldered in, then the shift register inserted into the socket?

As to connecting the LCD - am I correct that I need 2 6-wire ribbon cables (or similar solution) to run from the shield to the LCD?

I think that's it (for the moment). I've been digging around these threads for a couple of weeks, and it's a little overwhelming.

Thanks in advance for any help - sorry if these are pretty basic!

im having a bit of trouble w/ the pcbs.io website not being able to process my payment for the pcb boards, so im wondering if i could just take the EAGLE file(s) from the github and get these boards through another manufacturer (i.e., the OSHPark website mentioned earlier in this thread). if i understand this correctly, the EAGLE files have the .brd extension? also, am i correct in assuming that a two-layer pcb refers to tracing on both side of the board?

alright perfect, thank you! the images looked correct on OSHPark (aside from the missing brewpi remix logo on the silkscreen of the arduino uno protoboard). really excited to try and wrangle this thing together.

that's what it shows for me as well. i should've specified that it doesn't show the logo when i go to the next step where it breaks the board down further (under the 'top silkscreen' section). this is what i'm getting there:

i just figured the last paragraph explained it, maybe 400 DPI? idk.

That's weird. I know it's on the purple boards I have here. I can't say for certain it will show up when you receive it, but if not, it's just cosmetic.

The image is on layer 25 with the names.
