Note: This item is also available with a custom laser cut case, search ebay for item # 163930210931The case and its parts are NOT available as a separate item for purchase! Description:A fully assembled Code Practice Oscillator (CPO) based on our popular 'Trinity' CPO using a Twin T oscillator configuration. The Twin T gives a pure note compared to the square wave derived from say a 555 oscillator, this provides a more pleasing note and may allow longer practice sessions.This variation of the 'Trinity' CPO incorporates a Pitch control that allows the operator to 'tune' the note to their preferred frequency, by means of an on-board potentiometer.The range is approx. 400 Hz to 2000 Hz. Several smartphone apps are available that would allow you to adjust the tone precisely by having the app 'listen' to the output of the CPO, if you find difficulty in finding your desired tone by ear. Suitable for straight (non-iambic) keys only. We have also reduced the gain of the amplifier to allow easier personal training with earphones/earbuds.PCB size is 2.75" x 1.75" (70 mm x 45 mm).
