Inductor - 220 uH - red-red-brown silver - LF 1538 (resistive type) Resistor - 47k - yellow-purple-black-red and brown - RR 0612 (pkt of 8)Ĭapacitor - 68pF - ceramic x 2 - RC 5322 (pkt of 2) and a 100 or 120 pF value as well for experiments. I am adding the catalogue numbers for Jaycar Electronics, so if you live in Australia or North America, you may be able to visit a Jaycar store and buy the parts over the counter, if not then you may be able to do an online mail order via Paypal: You will need to acquire the following components from a local electronics shop or an online electronics business. See step 1 for the parts list you will need. The Tic Tac Radio is a very easy set to put together - you don't need to wind bulky coils or use heavy tools and screw strange looking parts onto a large breadboard. You don't have to solder any wires, but there is another way to join them all together - more on that later. The Tic Tac radio can be constructed by simply twisting the component leads together, underneath the matrix board and attaching antenna/ground wires as well as the earphone wires to the board, using that same technique. It is a very simple crystal set, designed to initially receive only one station, but you can expand the tuning range with the addition of only one extra component.

It is built on a square of matrix board, with the component leads poked through the holes in the board, and joined underneath. The radio is contained inside a Tic Tac box, and is called 'The Nic Nac Tic Tac Radio'.

We're going to build a 21st century style radio with all modern components which are relatively easy to obtain at your local electronics store or on the Internet. I built my first ever crystal set when I was 9 years old, but that was a different world. Parts can be bought 'off the shelf' at Jaycar Electronics and other suppliers, or purchased online via Ebay and Paypal. Hi there! This Instructable is all about building a basic crystal radio set that is so simple to build and understand, that a child could do it - with help from mum or dad - or even at school, as a class project.
