It's me, from that other site. Hacking on whatever grabs my interest at the time. Support my hacking habit at
I did the impossible. This is all I'm bringing to @defcon.bsky.social this year.
Put together another batch of my WiFi Shurikens. Loving the fact that I can just build custom tooling to help keep everything organized.
Life pro tip: Have a bunch of random gunk stuck in your silicone mat? Cover it in white glue. When it dries, you don't have to look at the gunk stuck on your mat anymore.
Thanks! Yeah, it's the rounded quarter round. Here's a test print for reference.
Also been working with @m0nkeydrag0n.bsky.social on a case for my WiFi Shuriken project. Most credit goes to him, I just have feedback. After a bit of back and forth, started maas printing today!
Been a busy few weeks and not everything was this past week. Redid my living room flooring and needed a rounded piece for around the steps. I modeled and printed it in wood PLA, then stained it to match.
I'm using a PicoGUS not quite as intended. I needed a sound card for a PC/104 board and realized that the pin ordering matched on the PicoGUS v1.2 and I could drop a header in place. Thanks @polpo.org for all your contributions to retro tech!
Got my new WiFi-Shuriken boards delivered and assembled today. They have 6x @seeedstudio.com Xiao ESP32-C5 boards and a Xiao RP2350. This thing is a scanning beast! Can scan both 2.4 and 5GHz bands in under 2 seconds.
The Pico controls the scanners over a SPI bus that should be able to steam WiFi metadata at over 2MB/s. I'm building out the protocol to be future proof so it should support 6GHz WiFi and HaLow once appropriate hardware becomes available.
Breaking stuff is just an opportunity to learn to fix it! I have been working on a high performance wardriving platform. My prototype has a Pico 2 managing GNSS, SD logging, and scanner orchestration. I currently have a single ESP32-C5 scanner, but the plan is to scale it up to dozens.
I'm in the early stages of building an escape room as a birthday present for my kid. I built out the majority of the infrastructure and now I'm working on individual puzzle elements. It took way too long, but I just got a phone ringing from external triggers.
I did some work with the ESP32-C5 this week. I replaced the Side B of the @jhewitt.net wardriver.uk with a C5. I had to strip out everything but Wi-Fi scanning, but it's a beast for 5GHz. In my tests, I saw about a 30% increase for 5GHz compared to BW16. Code available at github.com/CoD-Segfault...
Started working on moving the wardriver.uk code from Arduino to PlatformIO. It's a bit messy, but it does run! I have some plans to make a few enhancements, including potentially running the code on different hardware.
Broke 3M Wi-Fi found on @wiglenet.bsky.social today! Got a new color! #wardriving #AllTheWifi
Been working on restoring a payphone. A battery leaked and caused a bunch of rust and corrosion. Was able to clean up the boards fairly well. The solder mask seems to have protected the traces, but a couple of chips look crusty. Waiting on my ATA to arrive and I can see if it works.
I'm giving a talk about multimeters this weekend for @pancakescon.com! Thanks to @blenster.com for running the Hardware Hacking Village and for giving me the opportunity to present!
Who knew that @defcon.bsky.social inhuman badges held such power? I may or may not be human anymore. Maybe it was that bite from that goon...
Oh man, I wish I would have known. I could have powered my Pinecil on the flight!
My DOOM @hardhat.rocks hat is going to make another appearance at @defcon.bsky.social this year with some new tricks! It now plays MS-DOS #HackerJeopardy! Write your own category and I might put it on my head!
Been quiet lately, but still working on some stuff in the background. Today's milestone: A stripped down wardriver.uk side B running on the ESP32-C5.
Are you going to #THOTCON or @bsides312.org? Come find me for some @hardhat.rocks and Chicago-exclusive @wiglenet.bsky.social stickers. I'll be wearing my DOOM hard hat, so you won't be able to miss me.
