What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Howdy Y'all! Hurricane Harvey might have given Houston a hard hit this year but we hackers are tough to keep down. This year we wanted to bring a taste of Texas to DEF CON but weren't partial bringing 10-gallon hats, oversized belt buckles, and the casinos wouldn't take kindly to us rustling up some BBQ. 

So with the help of Macrofab, we’re providing a snake you might not wanna be treading on.

With the prices of PCB design getting cheaper, we decided to put together a bit of something to show some Texas pride. DC often has an official electronic badge but every year Hackers in #badgelife make their own unofficial badges. Working in coordination with other enterprising hackers from across the USA. This piece of flair is either powered by a small battery or piggybacked on a number of the many other excellent indie badges.

What does the snake do? Besides look amazing, and show Texan pride, the snake will light up when the throat circuit is closed (touched).

Don’t like that? Want to make it more special? You can! You can create your own trigger for when the snake gets ornery! Or give it a longer rattle tail! Or more LEDs!

Customize it to your heart's content!

Details: 

  •  3 LEDs (Eyes and Tail)
  • Throat Touch sensor
  • Can run on a small battery
  • Follows the "Shitty Add-on" architecture

Us Houstonians are trying to keep the price as low as possible but still give the best quality possible. So this KIT REQUIRES ASSEMBLY including surface soldering. Don't be scared though, the LEDs will already be in place so it's just some resistors and a lil ole through-hole NPN. There is an optional battery pack, and/or attach a tie tack to stab it into where ever you want it. (Please not other people) This is a good kit if you have done at least one soldering project before and have 30 minutes.

Components:

  • Pre-cut PCB Snake board (55x60 mm)
  • 3 LEDs (pre soldered)
  • 1 NPN
  • 3 resistors
  • 1 Battery holder and battery
  • 1 Backing

It is small enough to be attached to a lanyard or saddle up to another badge without breaking yer neck.

Risks and challenges

While I took electrical engineering as a prerequisite for weapon system engineering, it could be that a 14-year gap may have led to a misunderstanding of the circuit. To combat this, I have been working with some other badge designers through #badgelife to understand best practices for delivery in a stressful environment like Defcon.

The simplicity of design: To reduce my gap in experience, the badge is a straightforward circuit. There are no costly screens or components that can be broken and there are multiple redundancies fixable with a soldering iron and inexpensive parts.

Prototypes: Prototyping is being conducted to conduct robust testing and ensure that the manufacturer can produce the designed badge effectively.

Individual failing badges: We will be able to replace badges that we can not fix and do not work on arrival. We will be testing badges before shipping. While we will make our best effort to fix badges that are broken at either the conference or at Houston hacker meetups, users should be careful with them.

Robustness: This simple circuit will be more robust for surviving Blackhat/DEF CON and is easy to troubleshoot. Hacking and adding on is encouraged but understand that the addon may damage your badge if it draws or grounds too much voltage or amps.

Loss of parts: Many components are very cheap (under a dollar) to replace (or scavenge) if they break. Aesthetics may alter if improperly soldered. The board will be more challenging to fix.

Manufacturing failures: If manufacturing does fail, there are many other PCB providers that we will be able to work with, and we will have to move off the local Houston provider.

Limited Production: Production is limited so that we can provide full funding if some backers abandon us.
