That's more than I wanted it to be, but having a xiao that is arduino-reprogrammable via usb-c, 1.3" dual OLEDs instead of the typical 0.96", and finger cuffs are not cheap. dual soldermask badges, lanyards, two sets of batts, stickers, fingercuffs (for the GSR sensor), box, etc. I expect it to be sub $150 for everything. And selling at a friendly vendor booth requires them to collect tax since Tor doesn't have a non-profit booth this year. I don't have a price yet because I don't know my final costs on everything. Once I have the badges in hand and I know they work I'll finish ordering other necessary components like lanyards, batteries, boxes, etc. I'm hoping to work with a friendly vendor to help me sell these at their booth, but that is not confirmed yet. Here's a higher-res picture with the current state of the interface (there are some other modes besides this primary lie detector mode). I expect to have that available a few days before defcon starts so everyone can determine if it is worth it to them. I will post a video of the badge in action and all the features it has, if I ever get out of soldering-hell over here. There will be at least one challenge (that dreamed up) with a prize going to the winner Source is licensed under the permissive WTFPL
#Defcon 2021 how to
Source code and instructions on how to reflash the badge (via an arduino IDE) will be available prior to defcon on github.
If you choose to purchase a badge, thanks for supporting Tor. I do not charge for my time or effort, I only hope to recoup any material costs. I am not funded by anyone, I front all costs of development myself. Price - $120 including tax which includes the badge, custom lanyard, finger cuff cable, two sets of batts, stickers, and probably some googly eyesĪll profits from the sale of this badge go directly to the Tor project, just like 2 years ago. Hacker warehouse will have to charge tax as they are not a non-profit. Their booth will be in the vendor area of the conference, which I believe is open Thursday - Sunday (check the defcon schedule for details). Where to buy - Because Tor does not have a vendor booth this year, I've teamed up with hacker warehouse who has agreed to help sell them at their vendor booth. There is also 3.3v/gnd and other 0.1" holes available for prototyping. There are 0.1" headers for every pin on the xiao. There is one 1.69bis SAO header, finger cuffs used for the GSR sensor, and is run off two AA batts with a boost vreg to 3.3v.
#Defcon 2021 serial
The stock firmware also outputs the raw data over serial USB to allow further analysis of the data on a computer. Hardware - It is run off a cortex M0+ arduino based xiao, that you can connect to via USB-C.
Use it to interrogate your friends, or to practice how to get through your next fed-job interview The output of these sensors with some statistics is graphed to each of the two 1.3" OLED screens. These are two of the sensors used in a polygraph machine. The badge has two primary sensors, a GSR sensor and a heart rate sensor. What it does - It acts as a mini lie detector.
#Defcon 2021 upgrade
Where you control a factory zone, you can produce available units and possibly upgrade units. With influence, you can possibly destabilize zones or take political control of destabilized zones.
With research, you may unlock technologies. You collect resources (oil, uranium, influence, and research) depending on which zones (countries) you control. The game lasts multiple rounds, and each round has these steps: Each faction has its own technological tree, mission cards, objective cards, and unit pool. The game includes five factions: three major factions (USSR, USA, unaligned) and two minor factions (China and France). DEFCON 1, a game about the cold war, can be played by 2-5 players, with the game having different modes depending on the number of players.
