GVRET and BDC668 Disectors for Wireshark
Post Views: 27 This is a quick post about another non-quick rabbit hole. This Wireshark plugin sits on the same PC as SavvyCan and sniffs the interaction between SavvyCan and an ESP32RET CANbus sniffer. It uses the Wireshark SocketCAN format to expose the GVRET can packets to further Wireshark disectors such as ISO-TP etc. If…

ESP32RET on an Adafruit ESP32-S3 TFT

Caterham SV Prop-Shaft Scan
Post Views: 32 The next in the list of things I’ve scanned is the prop-shaft from a Caterham Seven SV. It’s taken me a couple of years to get around to extracting this from the EV project car, but I need a model now to verify the CAD for the gearbox that’s being designed.
