Had a busy week so far, built these up:

Impressive. Do you have a link to a description of these devices?

Only a fairly vague one - essentially it's just a pulse counter/measurer - it measures the width of pulses, counts the number of pulses, and calculates the flow of water through a water meter. It also incorporates a pulse output as well, so can be used to supply pulses to test other equipment. Needless to say it uses a PIC

Nobody else makes anything like it, and it was one of the first products I came up with - we even use them ourselves here for various purposes.

The later versions use the SMT to do all the readings, it's made life a lot easier once the SMT became available - previously I was using interrupts to extend the range of the counter timer, but now it's easy to time in microseconds with 24 bit resolution. If the counter times out, I consider that as no pulses.

We've sold a good few hundred of them, and we a good profit - expensive parts are the keypad/label, the case (supplied ready machined from Hammond), and the mil spec sockets on the front. Everything else is pretty low cost - the LCD display is a bit tricky, as it's a smaller size than the usual ones, and it was a question of finding something that would fit the Hammond boxes.

I can't believe no one makes a nice little handheld case that is ready built to accept standard LCD modules?.

And if they did, they would of course be the wrong size

Oops - bit of a mistake, the boxes aren't from Hammond, they are from Camdenboss - we get different boxes from both of them.

Quick PIC's of the inside:

Nigel,
is that you in the video?

Perhaps I'm been a little dim here?, what video?.

 

[JimB]

what video?.

The video about the water meter monitor which you have made.
(I had to hunt a bit to find it).

No it wasn't me, my boss took the video, and the guy was just a waterboard employee.

I'm not that young
