I've been using a raspberry-pi 5 to run a metal detector, and yes it is a power-hungry , > 10 Watts, beast.
However,
1. Wireless 'LS' gaming headphones with dedicated wireless 2.4gHz dongle are fast, with no noticeable lag. So finally I can have wireless audio for less than $100
2. All processing and audio is happening on the pi and is written in python, its' extremely fast.
3. The full development system: 'VS code', python, desktop, is on the actual raspberry pi. I 'log on' to the detector and make changes (!)
4. Most importantly, I have a browser open to ai (claude) and it tells me how to do everything, who knew we would live in such a time ?
In summary : The electronics and the fast sampling, the most important part , is all external. The averaged samples are sent over USB to the Raspberry pi at 25 float values 20 x per second . (1 Meg bit per second usb serial)
Below are web pages running on the pi and show real-time data. Can connect to the pi hotspot with a phone and display the data on the phones' browser:
all code is available on wombatpi.
