In addition, the endless loop playback feature makes the Bullshooter a truly unique device. A quick push of the RECORD and PLAY buttons sets up the BS2C to record up to a full eight minutes of audio, depending on how you have set up the sample rate, and what message location you start at (See “Using the BS2C”). -
Page 5: Circuit Description
IC for this. The BS2C power supply: The power supply is fairly basic in that we only need a single voltage to run the entire kit. The trend these days is to run things from lower voltages for faster operation and less power requirements, so all of the parts in the BS2C run from 3.3V. - Page 6 RCA type connections. It also provides for a bit of filtering and some gain control to better match your system levels. These are the primary blocks of circuitry in the BS2C. Now it is time to collect your soldering iron, tools, and wits, and start putting this neat project together!

BS2C ASSEMBLY Use the boxes to check off your progress. Check all received parts against the Parts list on page 7 and 8. The parts list describes the various markings that may be found on the kit parts.
- Page 11 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 12 which means that it must be installed in the proper orientation to work correctly. You’ll note that there’s a stripe or band at one end of the part and a band marked on the PC board silkscreen and Parts Layout Diagram. Align the two bands and solder the diode in place.
- Page 13 Those last few parts are the power supply section of our kit, taking the raw DC input to the kit and smoothing it out for all the circuits. Ready to move 13. Install R3, 10k ohms (brown-black-orange). Resistors can be installed in either direction but your kit will look better if you have all the gold bands lined up the same way.

Install R11, another 2.2k ohm resistor (red-red-red). 33. Install R16, 2.2k ohms (red-red-red). It’s hiding between the MIC and LINE IN jacks.
- Page 17 47. Install R19, 10k ohms (brown-black-orange). 48. Install R15, 330 ohms (orange-orange-brown). 49. Install R20, 21, and 22, all 10k ohms (brown-black-orange). 50. Now we’ll move to the other end of the PC board. Install C6, 10uF electrolytic capacitor. Watch orientation! 51.
- Page 18 flat side on the part. Line these flat sides up and the diodes will be installed correctly. If installed backwards they will never light. Install D6, the red LED, by correctly orienting the flat side on the part with the flat side shown on the PC board silkscreen and Parts Layout Diagram.
- Page 19 • Solder shorts between components. Check your schematic and parts layout diagrams if you suspect a fault. • Proper orientation of diodes, capacitors, and ICs. • Ensure proper power supply polarity and voltage (5 to 12 volts DC, center positive) All finished checking your kit over? I went and got a glass of water to give you time to thoroughly examine your solder joints and parts placement, knowing that you wouldn’t want to leave me sitting here idly waiting for you.

Page 20: Initial Testing And Operation
INITIAL TESTING AND OPERATION Power Supply Considerations The BS2C is designed to run off an external source of 5 to 12 VDC. Batteries, power supplies, or AC adapters may be connected to the unit through the power jack, J1. Care should be taken to ensure that the center tip is positive. -
Page 21: Using The Bs2C
Using the BS2C Recorder Layout The BS2C’s memory is laid out like a timeline, and the BS2C software can jump to any absolute position within that line. You can think of it like a piece of tape laid out in a long strip. It is then divided into eight equal pieces that mark the start point for any one of eight messages. - Page 22 To change the sample rate of the BS2C, power it down, then press and hold the PAUSE button while powering the unit on. The display will show three dashes to indicate sample rate selection. Now press the UP DOWN keys to select from one of four sample rates.
- Page 23 30 seconds. Pretty simple, but something to keep in mind. To turn the repeat mode back off again, turn off the BS2C, and then power it back up while pressing just the RECORD key. The BS2C will go back to nor- mal mode and save the settings.

CASE UP INSTRUCTIONS: The enclosure is a key element to the overall pride you will have upon com- pleting your Ramsey kit. The enclosure will show how you were able to “build from scratch” a commercial piece of high-tech electronics. For some of us, the enclosure will also hide a number of “not-so-pretty”... -

TROUBLESHOOTING Won’t record from Microphone and/or Line In. 1. Check to make sure you have the proper recording mode selected. The decimal point on the numeric display indicates the mode. If in microphone mode, the LED is off. If in line-record mode, the LED is on. Check your source and be sure you don’t have both an external microphone and a line level audio source plugged in at the same time. -
Page 27: Warranty
The Ramsey Kit Warranty Please read carefully BEFORE calling or writing in about your kit. Most problems can be solved without contacting the factory. Notice that this is not a "fine print" warranty. We want you to understand your rights and ours too! All Ramsey kits will work if assembled properly. -
