Episode 244: Ben Heck’s Raspberry Pi Zero Portable Episode

Im not sure if I'm too late, but i think that the pins are defined in the keypad driver source, in the 'define' section:

#define col0  22

#define col1  10

#define col2  9

#define col3  11

#define col4  5

#define col5  6

#define col6  13

#define col7  19

#define col8  26

#define col9  7

#define col10 12

#define col11 16

#define col12 20

#define col13 21

 

 

#define row0 27

#define row1 17

#define row2 4

#define row3 23

#define row4 24

So column 0 (the first column) is pin 22, row 0 (the first row) is pin 27, etc. If i'm wrong I'd love to know before I try to use this myself, but that's what I think so far.

Edit: ok so those are the broadcom chip pins, which translate to the pi pins like this:

You can see the broadcom numbers as GPIO#

So col0 = GPIO22 = pin15

Its a bit complicated but I hope this helps.

A s7 edge screen on that would be joy

I'm trying to make my own copy of this but I don't see which pins were used for the keyboard matrix I looked over the files and don't see which were used please help.

That might depend on the program you are using to open them or if Ben saved in metric or SAE measurements, then which your program is set to. I've seen 3D design/printer programs scale files strangely due to these factors.

hi

way are the stl files broken =? 

all parts have the wrong size !°

Thanks for the heads up. Looks like Ben had some of the layers turned off when he saved so it doesn't translate to older versions of AI. I'm having them fix it and Felix will update the file on github. Watch for the commit to be more current than July 4th.

Mr. Heckendore when I downloaded your Pi zero portable build guide I discovered that there isn't the laser cut parts included ) :

Can you Please update it as soon as possible PLEASE and include hose laser cutting files.

Well I think he used:

Lithium Polymer battery 3.7v 2500mAh

Powerboost 1000c

Raspberry pi zero

Slide Switch

4.3inch Lcd camera monitor

Alright now we have to see this amazing Pikedex for real!!! 8)

I etched a PCB for the filter circuit and soldered everything up. It sounds much better. https://www.youtube.com/watch?v=ZgBQyksaOro
