I have thousands of videos on YouTube covering a wide range of subjects. To find them follow my search guides https://youtu.be/ceBSOoOHcgw or https://youtu.be/Zj4UgwkwYRk or see my playlists page https://www.youtube.com/user/GrandadIsAnOldMan/playlists?flow=grid&view=1
Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
