Any chance of getting it developed commercialy? I'm sure there would be a market for it.

I am surprised cycle cameras do not already come with this type of thing built in, especially considering the price of some of them.
e.g. a built in doppler radar to display speed of oncoming vehicles.

I like the idea of people building these themselves to use/experiment with
They are very cheap and the esp32 has built in wifi and bluetooth so the possibilities of where people could take this are endless...
It would be a great way of getting in to electronics/coding.

The esp32cam is perhaps not the best first "Arduino type board" as it does not have built in usb but it does have the sd card built in so in this case I think it a good choice even if you do not plan to use the camera.
I try to put lots of comments in the code so you can follow how it works: https://github.com/alanesq/ESP32Cam-ran ... -range.ino

Just posting some more sample data in case anyone is interested:

This is captured whilst cycling along a pretty standard main road for a few hundred meters or so.
Interestingly, of the 9 vehicles which overtook me, it looks like only 4 were 1.5 meters+ from me (and this is measured from my cycle frame not my shoulder).
It seems to only have a reliable range of around 2.5m, not sure why as it is claimed to be 4.5m

Very neat - i've been meaning to do this for a while, and have a bunch of parts after seeing this https://www.bikebiz.com/bike-blogger-cr ... s-o-meter/ a few years ago, but failed to make the time. Might make time over winter this year...

I have tried unsuccesfully to get my local council to put up signs similar to those you see in Spain .....How about a CTC campaign to do something like this in the U.K. ? I am sure this would have great support within the membership. Can anybody on here take this forward ?

That is discussed in viewtopic.php?f=6&t=139167

Here's a thread about this

And something more recent

Not sure the threads say very much other than there is a very diverse group of people on here..........I do think those signs are great though. It is amazing how many drivers in th U.K. have no idea how much space they should give cyclists...Okay a lot will ignore the distance rule anyway but getting the message out there with simple, well designed signs will surely help.

You asked about a CTC campaign. Those threads cover what the successor organisation is doing/ has done.
