I have purchased various products from the Elektor webshop, including a bat detector, several issues of the magazine as downloads and a trial membership, but the most useful of all in my opinion is the TV Simulator. It is also what I use the most. I like to go on holiday, and because my home is left unattended when I am away I was looking for something that would give the impression that someone was at home. That is why I bought the TV Simulator from Elektor. It proved to be a good product and very easy to build. The SMD parts were already mounted on the PCB, so I only had to mount the LEDs and a few wired components on the bottom of the PCB. After that it didn’t take long to fit the board in a suitable case and fold the small piece of transparent paper in place, and the simulator was ready to use. After switching it on I naturally tried it out in the room with the television set, to see what it looked like from outside. It really is just like having the TV on! All in all, this device has come in handy for me several times already. It’s a real boon for the holiday period and for evenings when there is nobody at home.
