Unusual use of a Windows 10 computer in lockdown conditions ...
After the first lockdown started in March my hair round the back was approaching collar-length in June so I had a go with my late wife's hair clippers which have number settings - what could go wrong!
Looking in mirrors my hands moved in opposite directions to what I could see and I found it very difficult. Afterwards my hair was shorter but did not look at all good. Lockdown then lifted and a visit to the barbers in July gave me a decent haircut.
Another lockdown is now in force with visits to barbers not allowed and my hair was again approaching collar-length so something new was needed.
I have a detachable webcam on my Win 10 desktop computer and set it up on a stand so that when I looked at my 24" screen I had a perfect view of the back of my head. I set the numbers on the clippers and had a go. It was easy, my hands moved in the right directions and with careful moves gave myself a very presentable trim round the back.
I then repositioned the stand and webcam to side views and carefully trimmed as required. The webcam took a video of the entire process.
I was well pleased with the results ...
