Pipeline #47923210 failed with stages
in 1 minute and 21 seconds
To slice, I used Slic3r.
I'm using a .4mm nozzle, with .2mm layer height for all layers
I set infill to 40%, honeycomb.
I set Horizontal shells (bottom AND top) to 0. This expresses the infill to the seethrough effect I have
Once you regenerate the slice, view the layers tab on the bottom of the 3d interface.
You want to check and verify the layers are doing what you want.
Once you're happy with how the lid effect is expressed, generate the GCode and send to printer
This is a list of materials you will need to complete this tablet.
Please be aware, that since the product links are to a variety of auction sites, these prices **WILL** change. I also considered a few things as 0 cost. For example, USB cables are ubiquitious. We cut a few up.
I also have a large format 3d printer. You probably don't. I didn't include cost for printables, or nuts and bolts. I buy in quantity from Fastenal or McMaster Carr.
Total cost tally as of 17 Feb 2019: $157.50

NOTE: If you redesign the back cover for M3 nuts, you can use them instead. It won't look as finished, but will certainly work.

This is the repository for a Signals Intelligence Tablet, as I will be discussing at the 2019 CircleCityCon
--------------------------------------------
“Who said something? What did they say? Where did they say it? What can I do with it?” These are the questions people have when working with unknown radio systems. This is the art and science of Signals Intelligence (SigInt).
We discuss the basic requirements for working with SigInt, along with a sample platform using a Raspberry Pi and a RTLSDR radio receiver. The discussion will then briefly touch on other hardware that can enable SigInt work, that are not incorporated in the demo platform. We then dive into the software stack that makes SigInt work.
The following software will be used: Linux (Raspbian), RPITX, RTLSDR libraries, GnuRadio (gr-inspector), GQRX, and other accompanying tools. We will use FCC ID’s, manual scanning of spectrum, and gr-inspector to find and target potentially vulnerable frequencies and protocols as well as show how exploits could commence. We will attempt a live demo of such an attack using a system the presenter brings in.
--------------------------------------------
This document will be populated appropriately showing an assembly, recommended 3d printing settings, electrical routing, and configurations for the Raspbian and accompanying software.
