Perhaps try www.jaycar.co.nz for a local source.




Keep calm, and carry on posting.

TradeMe pricing is better than Jaycar, but if you can wait for delivery aliexpress.com has quite a bit of stuff.

Just be aware that most of the cheap ones use a fake FTDI chip which the latest FDTI driver will temporarily brick when installed.

So just be sure you have installed the older driver before plugging into a windows machine, and get a clone from DX or ebay or aliexpress.

But before you go making a parking sensor, see what they actually cost online and it will probably be less than rolling your own.

thanks. the ones you can buy are fugly.
this is a new house build and ive allowed some draw tapes in the wall for the sensors.
itll basically have a normal flush box plate on the wall with the LEDS in it and a lower flush box for the ultrasonic... it'll look pretty good . it will be powered by a 230v/ usb power supply that will come on with the garage door light..
i see theres a few different unos on ebay seems to be an older one and a newer one??

Nicegear are my preferred supplier. NZ owned and operated. They sell Freetronics gear, like Jaycar as well, but you're supporting a local Timaru operation. Seeduino is a nice cheap intro into Arduino, and they work really well.
Everything they have in stock arrives overnight after payment.

You can always get the $30 parking sensor and gut it and put the guts into a flushplate etc. If you are doing something permanant then get one of the pro arduinos so you can solder it to some protoboard and then solder wires into the board too. The pushing wires into the arduino headers sucks at best and always comes loose over time. He wasnt using an arduino but a bare AVR chip and other stuff on a breadboard. no idea what he made up as it was half an hour long.

Rs-online is good. Has cheap prices and if it's in Stock I've had items arrive a couple hours later.

I got one of these a couple years ago from Amazon which I've been pretty happy with.

As richms suggested it might be easier\cheaper to gut one of these for the required parts.

Thanks guys. hacking an existing one is an option though most of the ones I saw have fixed distances e.g 3 feet 4 feet. the arduino I can custom set the distance.
anyone know of an off the shelf one that has learnable or adjustable distance?

I happened to come across an ebay store with impressive shipping times. Ordered stuff from these stores (according to envelopes they all came from the same guy/warehouse) on the 15th, was here on the 23rd.

One. Two. Three.

When I installed my one you put the car in the desired stopping position with the wall-mounted sensor directed at the bumper and turn the unit on.  It learns and uses that distance for the red light setting (until the unit loses power).  The minimum distance required is 40cm between sensor and bumper (maximum is ~5meters though I've not tested this).
The yellow\green lights are not configurable.

Looks like this one will be the most suitable. only has to drive 3 leds and take the signal from the ultrasonic sensor. squeeze it into a flushbox
