So I did not “complete” my hat until very late Friday when i finally got it to announce its link status on its new set of 14 segment displays. It performed admirably all weekend. Thanks to Paul for safely transporting it to and from Vegas. I must also thank Stephen for his late night help on Wednesday. (tacos are not enough) Without his amazing soldering, i’d still be trying to figure out what i had done wrong. Here are some pictures from that night and the con to follow. . .
Originally my router/PBX this Dell P4 was installed with some of the earliest Digium PCI analogue cards. This card supported both FXS and FXO modules, and i used them both in various configurations. One of the FXS modules is what allowed my housemate’s old rotary phone to connect to the house phone system. I loved testing the system by ringing his phone. The ringing of its actual bell, was a delight. That dell survived the infamous flood (by already being decommissioned). I think I paid over $200 for this card alone. Now i run Asterisk off my Raspberry Pi with a total hardware cost considerably less than that.
After Google killed XMPP support for Google Voice, I no longer had a house phone. I was using my Google Voice number as a home phone and for the gate info our building. This lead to the whole system being ignored and neglected. By the time the SD card gave up the ghost, even the backups were in poor shape. I rebuilt the whole system fresh from the latest RasPBX dist and it’s working better then ever. Bought a real DID so i could continue to use Google Voice on our handsets at home. It’s great to have my Asterisk back.
I met a pile of incredible people. Bought some amazing toys (for science), some i’ve even got working. Saw some talks and demos. Talked to some of my heroes and listened to even more. I saw Ladar Levison talk about epoxying your ports and adding thermite to your hard drives. I played with the ECU of a fake car! now i just have finish building the DarkNet Badge! enjoy my pictures. The hat data is still being analyzed. I’ll try to build something out of it eventually.
This is a silly project that i have spent probably too much time on. First I thought, why not time-lapse my upcoming defcon trip. Then i thought, why not live stream it. So… I started with a Pi Zero and a Pi Camera v1. Wired some pins to the GPIO for power. Made a custom wire and hot glued it into the hat. Done!
