I got my ELM usb adapter from SECONS in Prague, around 100 years ago. You can tell it's old by the brass and mahogany case it's in. (KIDDING!) Also the fact that it uses a USB mini connector.

2022-12-10 back looking at this, at least a hundred years have elapsed (Linux time) since I started this page.
CAN interfaces
Pi CAN Board Controller Area Network based on the MCP2515 controller.
There is the WICAN from Meat Pi, based on the ESP32C3, here is their github page. https://github.com/meatpiHQ/wican-fw
SEEED Studio CAN-BUS module and the ODB II CAN BUS development kit, each about about $20

There is a newer Seeed Studio CAN BUS module, $4.90, I bought two, from Digikey.
Software: https://github.com/nopnop2002/esp-idf-CANBus-Monitor There is an ESP32-C3 version.
Dashboards
"RealDash" looks like it might be fun. It runs on Android, maybe I could use an old phone or tablet. I have enough of those now.
Circuit Cellar article: eDash Robin Brophy Sep 2011 issue 254
microOBD
Sparkfun UBM32 controller: USB 32-Bit Whacker - PIC32MX795 Development Board $40
320x240 LCD
Resources
Elm Electronics the folks who make the interface.
OBDtester and pyOBD
OBD Auto Doctor Free and paid versions, including Linux. The paid version is $20 per year.
Python
There are around 700 forks of pyobd... the one that shows up in pypi.org I think appears to be Brendan Whitfield's.
This one looks interesting too though. barracuda-fsh / pyobd
