Hey @samstonehill
This looks like a fun project as I see a lot of kids getting involved. Though I feel for the slugs maybe one could try it with a lower voltage and see if it still does the job so that the slugs are driven away without any harm.
Indeed a very ingenious project and deserves applause and plenty of attention.
Looking at all the green in the open spaces you share in your post I am tempted to share todays daily prompt on leo threads which is #greentuesday
I see posts with a lot of greens and The occasional Slugs photobombing the image.
If you tell these people about your DIY invention here
it would be might help
Let me know if you need any help logging onto leo threads with your existing hive user name.
A little tip: you can do it easily using the hive keychain.
