I don't actually know how to obtain an update but seeing as it is working well at the moment, I think I will leave it as it is!

RDS

Thanks Joan, mine returns 0.6.0a3.
I am using Python 3 so I enclosed the Item to be printed in Brackets.

This seems lower than the version you quoted, unless Python 3 is different?

RDS

I was away for 3 weeks from the beginning of September, so I switched my Pi off completely. Since I returned and switched it on again, it has been almost faultless and in fact I have not seen any spurious pulses at all. I have read on another thread tonight about another member having problems with ...

@RaTTuS
Thanks, that's a good point, I had not considered!

Is there a spec somewhere for the Ordinary Pi Camera, showing the Lux level that it works at, because maybe that one would be suitable for my needs. I just want to experiment with Time Lapse.

RDS

Thank you, I was hoping that would be the answer.

RDS

Apologies in advance for such a basic question but I would like buy the Pi camera and be able to use it in Darkness or Daylight conditions. I understand that I need the NOIR version for Night Time use but can the NOIR version also be used in Daylight conditions.

RDS

I have not tried it yet but this looks very useful.
Thanks for sharing.

Thanks but when looking for details about Immersun, I came across this page: https://www.immersun.co.uk/

I designed and built a Scalextric Lap counter about 25 - 30 years ago, using logic chips. I struggled for quite while with how to identify when a car completed a lap initially by trying to shine a light across the slot etc. Eventually, I had complete success by cutting the live portion of the track,...

@promzguru
It is as stderr has stated but very easily shows the output of the GPIO.
It may not fully suit what you need but I think it could be a very good start.

RDS

Have a look at 'Piscope'.
As long as you have your sensor wired in to one of the GPIO's, this excellent program will display the output.

RDS

What Hardware are you planning on using for monitoring the Heart Rate.

RDS

@asandford How long are the wires? Are they screened? Do you find that when the fridge/freezer/boiler switches on that things go wrong? If you are measuring pulses over any sort of distance, have you considered twisted pair wires and an op amp? In response to your post on the other persons thread in...

@asandford
Thank you for your reply. Sorry, I didn't intend to hijack this thread, so can we continue this discussion on my original thread that I have brought back to the top by responding to your points.

RDS

@zesid I was interested to see your thread because I raised a thread back in May 2016 called, 'Spurious Readings - Help Requested' because my system picks up random pulse changes at times. I have not found an acceptable solution and it is made worse by the fact that my system suns perfectly most of ...

RDS

It seems to me that Trebor37 asked a relatively simple question about variables and got a very comprehensive but complicated answer about the 'list' function.

RDS

Thank you all very much for taking the time to help me.
This Forum is amazing for the speed and quality of responses from other members.

RDS

@Paeryn
Thank you. Your 1st example seems to be just what I need.

RDS

@Paeryn
Thank you, that is another very useful alternative.

RDS

@joan Excellent, thank you very much. That is exactly what I wanted (and I can't believe how close your 'rather than' example is to what I was actually trying!) Just for completeness, I have attached my version (that doesn't work correctly) below. for item in dailyunit: print(item) Incidentally, is ...

RDS

Sorry, the language is Python 3.

RDS

Not sure if it is a recommended way but I always select the output window and then use CTRL C, to stop a program.

RDS

I am using the 'list' command to store some data. Eventually it will have about 35 elements (or maybe they are called items) but to learn how to use the command, I have started with just 12 elements. I have successfully created the list and I can print the entire contents of the list or just selecte...

RDS

@pluggy
I have both types already.

RDS

@Major Tom
Thank you for your comments and suggestions.

Surprisingly, the Tank is not insulated, so the top of the Tank gives a very good indication of temperature inside.
Unfortunately I can only access (easily) the top of the Tank, so a strap around it is not possible.
