MG MGF Technical - DIY Low Water Level Detector

Today I've finished the prototype of my Low Water Level Detector and thought I would share it :) I've started this one year ago when I read about it on AP Tony's website.

I've made an LED in the spare warning light of the dashboard. With some inmagnination it even looks like a small water tank ;)

I've build the schematic round a PIC micro controller. I've written the software in "JAL"

Anyway, on to the results:

Pic 1, warning light ON

It's a little brighter than all the other lights but there's not much in it.

Pic 2, the home-brew controller box :)

Movie 2, Low water level detected for about 20 seconds*

* the blinking seems random but this is because is blinks with about 5Hz and the camera has a low frame capture rate. IRL it's a 100% constant 5Hz ;)

Nice work Sander! Interesting to note that you're using the same warning light as I am for my B&G warning system! LOL

Hope you are planning to put your build instructions on line?
Rob Bell

Thanks Rob,

Don't know if instructions will be very usefull in this case ? I've used the micro which is cheap if you allready have the programmer/devellopment kit but if you have to buy everything a B&G kit would be allot cheaper ?

Sander

Sander,

looks good :)
I'm still stuck on a direct beeper connection to the sensor ;)
A circuit with PIC12F629 was made by a german recently and I still need to get it in.
Rob, the place you used is quite known public. I go for the same, of course.

This is some pics of getting the mechanical stuff to the car without water loss.

You're right of course Dieter - the catalyst over heat symbol is the logical choice for the warning light on Mk1 MGFs. I wonder which lamp would be used on Mk2s and TFs?

Look forward to reading about it soon! :o)
Rob Bell

That is a very nice job Sander. Give us instructions :)
