Packet Potato

The Packet Potato is a Wi-Fi packet analyzer! Or... is it a spectrum analyzer? Well, nobody really knows, but either way, it's the worst one of those two things, ever.

The Packet Potato uses an ESP8266 that listens for 802.11 frames on a specific channel. The channel is configurable by pressing the "+" and "-" buttons, and displayed on the 14-segment display. As it receives a frame, it blinks the appropriate LED's to indicate some things about the 802.11 frame that it heard.

Build Instructions

The Packet Potato is designed to be easy-to-solder, with all through-hole components. You can find the build instructions here:

Firmware

Firmware is currently available on GitHub in uncompiled form. I'll compile it soon, and package up instructions to make it easier to flash your Packet Potato with the latest firmware.

Soldering Equipment

A few people have asked me what soldering equipment I recommend, so here's a list! All of these are Amazon Associates links, which means I get a lil' kickback if you use these.

  • Hakko FX888D Digital Soldering Station, $99 - This is what I personally use. It heats up very fast, and does a great job of flowing solder even on larger parts. The tips are replaceable, and I like that it includes a whole station in one package. The only downside is that it is 110v only.
  • Hakko Flush Cutters, $7 - One of my most-used tools. These somehow are fast, cheap, and good, all at the same time.
  • Hakko Wire Strippers, $15
  • Hakko Tweezers, $7 - Another essential tool. These are great for manipulating small, surface-mount parts.
  • Aven Circuit Board Holder, $11 - This one is critical. It holds your PCB's while you solder, but also allows you to quickly flip the board over to work on the other side. I bought one of these and immediately thought, "Why didn't I get one sooner?!"
  • Fluke 101 Multimeter, $40 - Simple, solid multimeter. I'm sure there are cheaper ones that do more... but this one is a legit Fluke!
  • Solder, $10
