    If you enjoy this kind of RF hacking tool, you may enjoy the Flipper Zero even more:

    It has 125kHz RFID (for cloning door access badges) and a 433 MHz transceiver (for cloning garage door / barrier remotes). This is much more desireable for me than Wifi.

    Wish I could get the same capabilities in a phone case format so I could clone all my different badges into something I carry with me all the time.

    I just today decided to build a Pwnagotchi[0], and I've got a spare M5Stack[1] sitting in a closet, so it looks like I now have two projects for this weekend!

    Even though the ESP family has been around for a while, I continue to be amazed by what people can accomplish with such resource constrained (by today's standards) embedded systems.

    Be careful what data you collect: https://en.m.wikipedia.org/wiki/Joffe_v._Google,_Inc.

    Love these types of projects. I built the pwnagotchi last weekend and documented the process on YT https://youtu.be/2DIPVpcjR1I

    I might have to find some part for this now...

    I have one of these lying around (and spent a couple of hours setting up an ESP32 camera to work with HomeKit, so this seems like a fun follow-up). The M5Stack range is loads of fun.

    I don't know how much confidence I would put into this, but there is an amazon listing: https://www.amazon.com/M5Stack-Development-Extensible-Contro...

    It seems like to protect against this, I should have a long password and not use words (e.g. mix numbers for letters). Is that correct?

    I would love if the software stack were extended for on the go usage:

    Use HashMonster to capture packets. Send those packets to my mobile phone via bluetooth. Phone sends it to my PC running at home via mobile data plan. PC cracks the password, returns back to phone.

    That way I can crack passwords to wifis while waiting somewhere if I dont want to eat my data limit

    kinda amazed you can get a microcontroller SOC board w/ case, battery and a screen for about 50 bucks shipped.

    ESP32 is crazy versatile. Too busy and should not add more project but this is very interesting and the 433 one mentioned below.
