The UM66 chip was designed to play popular monophonic melodies: The chip used in this circuit plays several melodies. The UM66 is used two times. They are not synchronised. This DIY EMI has potentiometers to control voltage starve & volume as well as a switch to change the ‘bent’ character of the sound. It is possible to use headers sockets for the ICs to allow them to be swapped, enabling user control over the output.
This version was designed with a Winter celebration in mind, hence the name FESTIVUS as celebrated in regions of Europe and beyond. Nollaig na mBan! (little/women’s christmas Ireland) Trettondedag (13th day Sweden) día de los Reyes Magos (3 kings day Spain), also; Epiphany.

(Battery not included.) These DIY EMIs require a 3v CR2032 battery for power. The output is a mono mini jack (3.5mm).
On this tape you will hear a series of examples intended to assist you in your journey. The examples on this tape are designed for you to run trials prior to your attempt to join. The 11 pieces will give basic directions and illustrate disruptions and interference experienced by the traveller on their journey.
The waymarkers are made using an FM transmitter these will play a continuous loop tuned to an agreed frequency. The traveller using a radio tuned to the frequency can then pick up the signal. Each loop can be used to impart information covertly, giving directions, warnings and other information. The pieces included here are simply the beginnings of the loops needed to traverse the land safely.
