ENCYCLOPEDIA OF RADIO ELECTRONICS AND ELECTRICAL ENGINEERING Keychain emotional setting. Encyclopedia of radio electronics and electrical engineering
Encyclopedia of radio electronics and electrical engineering / Electronics in medicine The development of purposefulness, verbal stimulation of the initiative, the mood to improve well-being and fight bad habits... Assistance in the development of these and other qualities will be provided by a device protected by the patent of the Russian Federation No. 2109523. Its design is submitted to the readers. The attractiveness of the development is given both by the availability of manufacturing the device in a home workshop, and by the proven method of self-suggestion according to Kue using elements of neurolinguistic programming, which underlies the operation of the device. As for the effectiveness of the device, it depends on many factors, including the duration of verbal exposure. The recommended term for the continuous influence of the suggestion formula, aimed, for example, at high-quality preparation for an exam, is from 10 to 30 days.
As can be seen from the circuit diagram, the ability mobilizer key fob includes a dual-frequency master oscillator DD1.1-DD1.3, a multi-digit binary counter DD2, DD3, a reprogrammable memory device (ROM) DD4, a digital-to-analog converter (DAC) R7-R14 and an output cascade DD1.4, the load of which is a BQ1 sound converter of the ZP-5 or ZP-22 type. When the power supply is turned on, the charge current begins to flow through the capacitor C4 and the resistor R6 and the installation (reset) of the microcircuits DD2, DD3 to the initial state is carried out. The output potential of the high-order digit of the counter (pin 13 DD2.2) becomes equal to logical "0" and opens DD1.3 (pin 9) and ROM (pins 20 and 22). Through the diode VD1, the input of the logic element DD1.3 is disconnected from pin 6 DD1.2. The generator (DD1.2 and DD1.3) generates clock pulses with a frequency depending on the capacitor C2 and resistors R3, R4. 16,11 or 8 kHz is preferred. Smooth frequency control is carried out by a variable resistor R4. Now the counter starts to work on the logic elements DD2.1 and DD3 with a synchronizing differential circuit C3R5. And since its output digits are connected to the ROM, the corresponding information is extracted - the components of the verbal suggestion formula, previously recorded in the form of codes in electronic memory. A digital-to-analog converter with resistors R7-R14 converts code combinations into an analog signal. To match the DAC with the audio converter is the output stage DD1.4, operating in linear mode. Moreover, to reduce noise, the latter is equipped with a low-pass filter (C5R15) with a cutoff frequency of about 16 kHz. After using the entire capacity of the ROM (32768 counts), the cycle of reading and decoding information is repeated if the jumper S1 is connected to pin 13 DD2.2 (double reproduction of the verbal formula). When S1 is connected to pin 12 DD2.2, the suggested phrase is played once, and to pin 14 four times. Logic "1", appearing on the corresponding output (12, 13 or 14) DD2.2, locks the ROM (pin 20, 22), as well as the output stage DD1.4 (pin 13) to reduce power consumption in pause mode and simultaneously disables DD1.3 (pin 9). On the elements DD1.1 and DD1.2, the master oscillator starts to work. Its frequency, determined by the values C1, R1, R3, R4, is the starting parameter when setting the time interval between suggestion phrases. In this case, the duration of the pause will be one-, two- or four times, depending on the connection of jumper S1 to terminals 12,13 or 14 of the logic element DD2.2. Strictly speaking, the pause continues until the appearance of a logical "0" on the output connected to jumper S1, after which the duty cycle (play + pause) is repeated. The duration of the one-time playback itself is determined by the choice of the frequency of the master oscillator operating on the elements DD1.2 and DD1.3 of the K561LE5 microcircuit, and is adjusted by the capacitor C2 together with the resistors R4, R4. Moreover, R120 is used mainly to adjust the "patter". It is recommended that this parameter, with the upper (according to the diagram) position of the variable resistor slider, correspond to 480, and with the right - XNUMX words per minute.
In order to reduce the dimensions of the product, you can go to replace R4 and R3 with one constant resistor, the value of which should be selected with an orientation towards the usual "patency" of 120 words per minute. To set it up, you need to turn on a milliammeter in the power circuit and time the sound of the suggested phrase with a stopwatch. With an operating frequency of 16 kHz and a "pronunciation" current of approximately 9 mA (and in the pause mode of about 3 mA), the duration of a single playback of a phrase should be within 2 s. For a frequency of 11 (or 8) kHz, with other conditions unchanged, the stopwatch readings of 3 s (or, respectively, 4 s) can serve as a guide. These frequencies are preferred because they are used in computer "sound" technologies. The duration of the pause is adjusted by the capacitor C1 and the resistor R1. Adjustment is performed on the readings of a milliammeter and a stopwatch with the indispensable consideration of the position of the jumper S1, which is directly related to the multiplicity of the work cycle. Recommended landmarks: 4-fold repetition and a pause of about 20 minutes. The sound quality of the suggestion formula depends on the synchronization of the counter (DD2.1, DD2.2 and DD3) by the C3R5 differential circuit. Naturally, the digital-to-analog converter also affects. The sound of suggestion formulas is perceived more "purely" if the resistances of the resistors included in the DAC correspond (as their serial number increases from R7 to R14) to a series of denominations decreasing with a division factor of 2. Phrases (verbal formulas) of suggestion should be motivatingly short and categorical, without the use of the "not" particle. Instead of an unconvincing stamp "DO NOT SMOK", positively perceived words-orders "QUIT SMOKING" or "AVOID SMOKING" should be used. When compiling the formula of suggestion, it is necessary to determine the ultimate goal as accurately as possible, not forgetting about the mood for its speedy achievement. For example, phrases such as "GET EXCELLENT IN EXAMS", "REPLACE "DRUGS" WITH SPORT", "NORMALIZE BLOOD PRESSURE" are effectively perceived. The ROM is "flashed" by a special programmer, the file for which is prepared using a personal computer (PC) with a sound card. So, in the wav 16 kHz (8 bit) format, you can record a sound with a duration of 2 seconds, using wav 11 kHz (8 bits) will provide a three-second, and wav 8 kHz (8 bits) a four-second recording. When creating files, the sound card driver, software menu and standard PC user technologies are used. First, the desired format is selected. For example, wav 11 kHz (8 bits). By the way, at the same 11 kHz, the key fob-mobilizer of abilities should work when it reproduces the suggestion formula at a normal speed, that is, with a period of a single reading of the ROM with a duration of 3 s. File preparation is greatly facilitated if specialized sound programs are used, such as Cool Edit 1.50. The effectiveness of the device is significantly increased if the suggestion formula sounds against a musical background. Therefore, when preparing a file for the programmer, mixing is recommended: a verbal recording plus fragments of some euphonious work. To do this, through a microphone or a line input, an excerpt of a piece of music you like is recorded on a PC disk with a sound duration of 30-60 s. Then, from the record made with the "mouse", sections are selected on the computer oscillogram 9-s, which, after listening, are copied via the clipboard to a new file. Having cut out from the selected and checked by ear the most suitable one, not exceeding 3 s in total sound duration, they transfer (again through the clipboard) the resulting slices of the future musical fragment into the next file with a well-remembered name-number assigned: for example, fragmnt1.wav. Similarly, about seven future musical accompaniments (from fragmnt1.wav to fragmnt7.wav) with different rhythms and tonality are prepared and stored in a directory created on a PC disk. Then they go to the file with the suggestion formula. The text is spoken in accordance with the above recommendations and recorded through the microphone input of the PC sound card in the selected wav format 11 kHz (8 bits). The phrase honed to perfection is pronounced 3-5 times with small (to facilitate the selection of the waveform) intervals. To obtain the desired intonation when writing the suggestion formula, it is advisable to mentally address the spoken words to the person lying on the couch. The most penetrating and short of the phrases is selected. After deleting "empty" sections from it using a computer oscillogram and making sure that the total duration of the sound does not exceed 3 s, the almost ready suggestion formula is transferred via the clipboard to a new file with the assignment of the appropriate (for example, "anti-smoking" bros_kur.wav) name for quick recognition . The third file is being prepared directly for input into the programmer - a ROM "firmware" device. It is created by mixing the previous terms already recorded on the PC: the suggestion formula and a pre-selected melodic fragment. It is at this stage that they strive to achieve that harmony, in which the rhythm and tonality of the musical accompaniment correspond as much as possible to the meaning of the words, and the level of its sound is approximately half as loud as the phrase itself. The mixed file is saved with an easily recognizable name, such as bros~kur.wav. "Firmware" ROM is performed in strict accordance with the instructions for the programmer. The signal coming from the file prepared for sewing should provide a playback volume at the whisper level. If there is no instruction, no programmer, or even a simple PC, then there is only one thing left: contact any of the cash register service companies. The equipment there, as a rule, is good, and the specialists are experienced. So, there is every reason to hope that the "firmware" of the ROM will be done well. The "stitched" ROM is soldered into a double-sided printed circuit board made of foil fiberglass. Author: A.Soloviev
