The AUTOTALK BOARD is a 9 Vdc / 20 mA powered control interface that will move a standard single hobby R/C type 5 Vdc servo in response to either an audio or speech input signal.

The AutoTalk controller includes the option to set both the maximum, minimum servo end points and servo travel motion direction.

AUTOTALK BOARD FEATURES:

· Board Size: 2-3/4" L x 2-1/2" W, Board is pre-assembled and tested.
· Setting the servo max. and min. points is easily done with a set of control potentiometer built onto the board.
· Connection pins on-board for servo, power hookups.
· An audio jack is on-board making it easy to connect any sound input cable directly to the interface board.
· AutoTalker Board is pre-assembled and tested.
· Adjustable sound gain
· Audio input jack socket (2.1mm).
· A 1 volt pp audio signal level is only required from an audio source to get maximum servo travel (90 degrees),
(microphone, tape, CD, sound system = 1 - volt signal output needed).
· The AutoTalk board selects either normal or reversed action depending on the relative positions for the shut
and open potentiometers with the JP1 jumper off.
· Jumper block and set the maximum travel position allowable for the servo

Power Supply and Servo not included.

Question:

How good is the synchronization of the motion to the sound?

Answer:

The audio to motion sync ratio is very good. ( One of the very best on the market today ) The electronics on the AutoTalk are very fast. Any incoming audio is very quickly converted. Where the difficult can sometimes happen in getting excellent synchronization, is with the actual servo. Servos are mechanical devices and require a certain amount of time to move the gears, motor, output shaft that make up the servo. The faster the servo moves mechanically, the better the sync with the electronics you will have. Using a quick moving servo connected to the AutoTalk will produce a very nice sound to motion ratio. Note: The AutoTalk will not operate servo motors that have an amplifier or booster built into the servo to increase speed and torque. These speciality servos require different electronics to operate.

Question:

Can the AutoTalk board operate from a digital sound board source.

Answer:

Yes, the AutoTalk board can be operate from a digital sound board source. The AutoTalk has on-board features (Jumper) to take advantage of the low signal output found on digital sound boards. The sound boards needs to produce a 0.5 V p/p level for the AutoTalk to take full advantage of the audio and move the servo in a full range of motion. The Sound Board Pro is an excellent choice to use if you need digital sound.

Question:	Can the AutoTalk board be operated from a Battery Power Supply?
Answer:	Yes, the AutoTalk board can be operated from a 7.5 Vdc R/C battery. You will not get as much operating time from the battery as from the wall power supply, but for remote operation a battery will work.

Question:	Can the AutoTalk board be operated from a Microphone for realtime voice control
Answer:	Yes, the AutoTalk board can be operated from an amplified Dynamic Microphone to allow you to control the servo with realtime voice. Note: The Dynamic Microphone should be the amplified type. If the Microphone is not amplified, than an optional Dynamic Micro Amplifier Board is needed to raise the input signal to a level that the AutoTalk can use.

Question:	Is the AutoTalk made in the USA?.............
Answer:	Yes, the AutoTalk board is assembled and tested in our USA electronic manufacturing facility in Maryland. Many of our other quality control boards are also assembled in the facility in Maryland.
