A short demonstration of two electronic components:

- "Smart Film" - a flexible opaque plastic sheet, which can be made transparent by passing an AC current across. I'm using an A4 size sheet bought from eBay for £35: ebay.co.uk/itm/210x297mm-white-smart-pdlc-switchable-glass-film-with-powersupply-vinyl/282559541535

- A Solid-State Relay (SSR), an electronic switch which allows you to control an AC load by applying a small DC current on the other side. I'm using a Fotek module which you can buy for about £2: ebay.co.uk/i/142674339945
