    In addition, the endless loop playback feature makes the Bullshooter a truly unique device. A quick push of the “Record” button sets up the BS1 to record up to a full eight minutes of audio. Use the on-board microphone to record a quick message or move the pc board mounted jumper to enable use of the line level input for recording from other sources;...

    D1, D2, and D3 together drop about 2 volts leaving a nice clean +3 volts required by U2. Most of the “magic” inside the BS1 lies within the ISD4004 IC (U2). This unique chip manages all the recording, audio storage, and playback functions requiring only address and control information from the microcontroller.

  • Page 12 Since you may appreciate some “warm-up” soldering practice as well as a chance to put some “landmarks” on the PC board, we’ll first install some of the larger components. Have a look at the Parts Layout Diagram to help with your assembly.
  • Page 13 As we head into the smaller components, remember to push each lead all the way through the board until the component body rests on the board. 12. Install C8, 10 µF electrolytic capacitor. Electrolytic capacitors are polarized with a (+) and (-) lead and must be installed in the correct orientation.

    The next group of components would best be classified as “ miscellaneous support components”. This doesn’t mean that they aren’t important, as without them the BS1 is just a paperweight. Bypass capacitors, pull-up resistors and a small oscillator comprise this group.
