BirdBox 2019: early interest (...plus hog & bats update)

Seeing small garden birds showing an interest in our bird boxes is a reminder that the nest box season will soon be upon us.


There is a long run in, a couple of months of building, egg laying and chick rearing, and then its all over for another year.


So make sure you are ready by putting up any new boxes now!

Gambas: using external C libraries

It may be useful sometimes to use C-language library functions in your Gambas programs.


There may be a performance advantage in writing your own C functions or you may simply wish to use existing C libraries.


Here are my notes which may help you get started.

The Linux programming language Gambas can use functions from external libraries.


This post gives a few simple examples to supplement the information in the Gambas Documentation.

Gambas Bat Recording Software for the UltraMic + Pi 3

As soon as Christmas was behind me, I found some time to progress my bat detector project.


I've been running the Dodotronic UltraMic with a Raspberry Pi 3 using re-written Gambas code...

Unable to read an SD card on Linux: SanDisk ExtremePro 64GB 95MB/s

For at least the last 10 years I've considered Linux to be the gold-standard operating system when checking memory devices.

 

If a drive could not be read on Windows, I'd test it on Linux to see if it had really failed.


But Linux didn't respond to an SD card recently, although the card was clearly working OK.

the Dodotronic UltraMic: first impressions

I just splashed out £225 on this USB microphone.


Initially I just plan to experiment & compare it with my home-made analogue bat recorder.


If all goes well this may turn into yet another bat detector/logger project.

Bats, Hogs & Hibernation

I used to think that 'hibernation' meant 'sleeping through the winter' in the sense that an animal went to sleep in November and woke up at the end of March.


Maybe this is why my tortoise died.


I stuck him in a cardboard box when I was 7, and only went back to wake him up in April.

KitchenPi: adding a watchdog

Although KitchenPi has been running well for over two and a half years, I do get the occasional blip.


A recent issue caused the system to fall silent.


But this turned into an opportunity to do a couple of simple software modifications.

Fixing my Pentax K-30 exposure problem: #4 more details on solenoid

I spent a jolly day thinking about the exposure solenoid and doing a few checks.


Everyone has a theory about why the green solenoid is problematic.


I've tried to work out how it operates...
