Could I record myself demonstrating a process such as soldering, making a cake or threading a sewing machine?

Yes indeed. We suggest you use Windows Movie Maker or Genee Toolbar to do this so that if you

wish to you can edit the file afterwards and make it into a quality learning and teaching resource

which could then also be posted onto a VLE and made available for download or viewing by

your students or audience whenever they wish. We know of lots of users who do this.
