Hans is interested in intercepting all kind of wireless technique. He intends to build his own IR device but discovers this ready-built unit that can turn off a TV from distance.
He buys the unit for 50 USD from Cornfield Electronics using PayPal.
Hans wonder if an inexpensive wireless door bell transmitter might disturb modern wireless car locks. The answer is yes! The transmitter in this unit sends a broad signal blocking the ordinary key when it uses the public frequency 433 MHz.
He buys a wireless door bell set for only 99 SEK at Rusta. The set includes both the door bell and the transmitter, including its 12 V battery.
