Evenin, I've been ttrying to pottering about trying to find the best way to undo the latch on my run door to let my girls out as it's dark when wifey leaves for work and not wanting to spend over £100 for a pop hole opener .
This is where I'm up to currently. This is a mock up to see if the principal worked and it appears to.
Some dental floss and a £6 2rpm disco ball motor thus far just need to water proof it all and use something a little better like strong fishing line and add a timer plug to run for one minute.
