ESP32 probe request sniffer

At first I started with the flock-you project to get a basic ESP32 monitor (promiscuous) mode dump of Wi-Fi SSID (directed) probe requests. But I could not get them this way.

removed the MAC and SSID filtering to show all packets
It seemed to only classify all packets as wild card probes. I saw no directed probes.
I tried to remove logic to find the offset of SSID in the probe requests to see the error and got lost

Tried to use a method that didn't use wifi_ieee80211_mac_hdr_t struct to somehow dump hex or strings of the contents, got confused, made little progress.

Headless installation of Raspberry Pi OS on ChromeOS (Bookworm)

This will get you a TF / MicroSD card with preconfigured headless Raspberry Pi OS with:

hostname configured
user account and password configured
wifi network and credentials to connect to Wi-Fi
SSH enabled
keyboard layout & timezone set (locale)

When someone submits a response to a Google Form, you get an email telling you that someone submitted a response but not what they actually submitted

That suuuucks.

So this project is meant to send you the actual response the person entered, and if you capture their email, the Reply feature in your email client will go back to the respondent.

Insert this code into the Script editor of the Google Form.
Copy the template into an HTML file in the script editor
Install a From form - On form submit trigger to call sendFormResponseByEmail() when someone submits the form.

	# without using the Google Home app at all, just using a normal Linux computer.
	#
	# You do need your Chromecast to be on Ethernet, or (untested) to join its setup WiFi
	# network with your PC, and you also need to find out its IP yourself with e.g.
	# Wireshark.
