Statistics

CanZE has no “phone home” capabilities, but Google acquires quite a bit of data and I thought it would be fun to give you a bit of an insight at what we’re up against. We are seeing a fairly consistent

Dash camera

While looking for some stretched screen, I came up with one of these new dash camera devices (1280×400 pixels). OK, the camera in itself doesn’t really interest me, because I only want to use it to make CanZE run on

Geek talk: ISO-TP and ELM327 dongles

Micro introduction: A CANbus, which is used to connect all computers in the car, can only carry chunks of 8 bytes plus an ID, called frames. All data used to actually operate the car, such as switch positions, speed, and

Dongle testing (more geek talk)

You might want to have a peek at this “Frankenstein contraption” testing rig. Things have moved on since (more on that in a later post), but this is how projects like this start. Note that I laid it out neatly

A DIY CanZE dongle, part 2. Geek talk.

We might have ironed out most issues with the DIY dongle. If there are people willing to build an ESP32 based dongle, especially if they own a Q90, R90, or R110 model, we would like to hear about it. Requirements

A DIY CanZE dongle

The KonnWEI dongles are, though the most stable in terms of what you get when you buy, not the best to run CanZE with, especially when fast performance is required. Think like the Driving, Braking and Consumption screens. For the

More BCB and filter pictures

Fred Leudon disassembled his Q model BCB himself and here a few of his pictures, now including the filter module! Note that what I earlier identified as the flyback diode is actually a 63 uH coil. Also visible is the

Only single phase charging failing.

Just like in brain research, often a lot can be learned when things go wrong. A friend driving a ZOE was struggling for months with the weirdest problem. The car charged fine on public chargers, but not at home. However,

Getting ZOE battery status into Node-RED

For those of you deep into home automation, using documentation compiled by Terrence Eden, me and Harm Otten wrote some Node-RED code to retrieve battery status from the same API that the the Renault Z.E. app uses. I’ve posted it

Volonteer wanted for Twizy

Thanks to the kind people running the OVMS project, we have access to quite a bit of documentation on the Twizy. Unfortunately, the current developers are unable to implement this knowledge into CanZE, mainly because lack of Twizy to play
