Audible Logic Probe Circuit Schematic

Audible Logic Probe Circuit Schematic Diagram

NE556 timer can be used as an indicator of static of digital logic audible terminal. Audible logic probe is useful for inspecting a part visually while we also need to check the logic state on other point far from the part. NE556 acts as an oscillator controlled by (SN74132N) and IC2 (SN7486N). Any logic transition from 0 to 1 and vice versa will be followed with audio beep, lasting at least 50 nanoseconds. LED provide visual indication. When the input logic is 1, the LED will glow.

lm317 3 3 v schematic diagram

lm317 3.3 v schematic diagram

The more expensive LM117 uses a 240 ohm resistor for R1. The LM317 is supposed to use a 120 om resistor or less so that its output voltage doesnt rise without a load if it has its max rated operating current and if its input voltage is high.

With 120 ohms for R1 and 360 ohms for R2 the output is 5.0V.
with 120 ohms for R1 and 200 ohms for R2 the output voltage is 3.333V.These resistors are common 5% values.

Simple Flashing Lights Schematic

This is a simple flashing lights schema can be used as beacon. The assembly consists basically of two blinking steps that commands two light bulbs. With the help of P1 you can adjust the flashing frequency between some limits. There are 2 parts for the schema, the second one works the same way as the other but with the help of a wire bridge or a switch you can choose different operating modes.A bridge between M and 3 means: 2 independent blinks.

Circuit diagram :
Flashing

Flashing Lights Schematic Circuit Diagram

If there is a bridge between M and 2, then the lamps lights alternatively with a frequency that can be adjusted with P1. And finally there is one more possibility for M and 1, where the lamps blinks at the same time. The flashing lights schema works with voltages between 3V and 15V. The lamps voltage must be 2/3 of working voltage. R5 and R10 are chosen so that the lamps are about to light.

Simple Sleeping Aid Schematic Wiring diagram Schematic

Many people experienced sleeping well in natural surroundings, into a tent or a wooden hut. This fact is due not only to the healthy atmosphere but also from our unconscious ability to perceive natural Earths magnetic-fields. The schema generates this type of Geo-magnetic-fields and lets us perceive them: in this manner our brain is surrounded by an ideal environment for a sound sleep. (N.B. Basic ideas for this schema are coming from German papers).

Circuit operation:

IC2C and IC2D generate two square waves at about 1.2 and 5 Hz respectively. These wave-forms are converted into 60µS pulses at the same frequencies by means of C5 & C6 and mixed at Q1 Base. This transistor drives the Radiator coil with a scalar series of pulses of 60µS length and 9V amplitude. IC1, IC2A & IC2B form the timer section.

C1 & R2 provide auto-reset of IC1 at switch-on. The internal oscillator of IC1 drives the 14 stage ripple counter and, after about 15 minutes, output pin 1 goes high. Pin 3 of IC2A goes low and stops IC2C & IC2D oscillation. If SW2 is left open (Alternate mode operation), after 15 minutes pin 1 of IC1 goes low, pin 3 of IC2A goes high and oscillators are enabled again.

If SW2 is closed (Stop mode operation), the first time output pin 1 of IC1 goes high, the internal oscillator of the IC is disabled by means of D1. Therefore the schema remains off until a reset pulse is applied to pin 12 by means of P1 or when the whole device is switched-off and then restarted. The same thing occurs when SW1 is switched on 30 or 60 minutes positions, obviously changing time length.

IC2B drives pilot LED D2 which operates in the following three modes:

flashes quickly and almost randomly when the Radiator coil is driven
flashes somewhat slowly and regularly when the Radiator coil is pausing during the Alternate mode operation
is off when the schema auto-stops (Stop mode operation)

SW2 = SPST Slider Switch
B1 = 9V PP3 Battery, Clip for PP3 Battery

Features:

Generates a natural electromagnetic-field
Makes easier to fall asleep
Induces a prolonged and sound sleep without drugs
No side effects

Use of this schema:

Select a timing option by means of the rotary switch SW1.
Choose 15, 30 or 60 minutes operation.
Select "Stop" or "Alternate" mode operation by means of SW2.
With SW2 closed (Stop mode operation) the electromagnetic radiation stops after the pre-set time is elapsed.
With SW2 opened (Alternate mode operation) the device operates for the pre-set time, then pauses for the same amount of time: this cycle repeats indefinitely.
Place the unit under the pillow and sleep like a log.
To reset a cycle press P1 pushbutton.

Notes:

L1 is obtained by winding randomly 600 turns of 0.2 mm. enameled wire on a 6 mm. diameter, 40 mm. long, steel bolt. Secure the winding with insulating tape.
Mean current drawing is about 7mA, decreasing to less than 4mA during pauses when in Alternate mode operation.
Battery life can be dramatically increased omitting LED D2 and its associated resistor R5.
Use a plastic box to enclose the schema: metal cases can severely limit electromagnetic radiation.
