When a baby tries to destroy your RaspberryPi touchscreen and terrorises your home automation application, you suddenly feel the need for some authentication. But since this baby can’t write and her face changes rapidly. You start to feed the need to invent something to outsmart her with a self-learning face recognition RaspberryPi cluster (or just because it is cool).
This talk will show a microservice application using thrift that runs on such a cluster. I will focus on face recognition with OpenCV and Tensorflow and how to make this a self-learning system.
Session Level: Beginner
This program creates a quiz buzzer using a seven segment display and buzzer. It defines arrays to store the digit values for the display and sets pins for the output, stop, and buzzer. The buzzer() function monitors the input switches and calls the display() function to show the digit and sound the buzzer when a switch is pressed, then waits for the stop pin to reset. The main() function initializes the pins and calls buzzer() to start the program.
The document describes a quiz competition with 6 multiple choice questions about companies and their founders. It provides details on the scoring format, with +20 for a correct answer and -10 for a wrong answer. Each question is only asked once and there is a penalty for buzzing in but not answering. The questions cover companies like Red Hat, Tata Docomo, Kochi IPL team, Lamborghini, Adidas and Puma, and identifies the employer with the second most employees as Indian Railways.
This circuit allows up to 8 players to buzz in during a quiz competition. It uses an IC and passive components to identify the first player to press their button. The circuit is divided into a power supply section and a quiz buzzer section. The power supply generates 5V from mains power. The buzzer section uses an octal latch IC to transfer the button press signals to corresponding outputs. When a button is pressed, the corresponding bulb lights and a buzzer sounds to identify the player.
This circuit is used in quiz shows to determine which of four contestants pressed a button first to indicate a fast reaction time. When a contestant presses their switch, a latch integrated circuit locks out the other contestants and a priority encoder converts the input to a binary coded decimal number that is displayed. An audio alarm also sounds to indicate a button press. The alarm and display are disabled by a reset button once the first contestant is identified.
Arm cortex (lpc 2148) based motor speedUday Wankar
The project is designed to control the speed of a DC and AC motor using an
ARM7 LPC2148 processor. The speed of motor is directly proportional to the voltage
applied across its terminals. Hence, if voltage across motor terminal is varied, then
speed can also be varied. This project uses the above principle to control the speed of
the motor by varying the duty cycle of the pulses applied to it, popularly known as
PWM control. The project uses input button interfaced to the processor, which are
used to control the speed of motor. Pulse Width Modulation is generated at the output
by the microcontroller as per the program. The program is written in Embedded C.
The average voltage given or the average current flowing through the motor
will change depending on the duty cycle, ON and OFF time of the pulses, so the speed
of the motor will change. A motor driver IC is interfaced to the ARM7 LPC2148
processor board for receiving PWM signals and delivering desired output for speed
control. Further the project can be enhanced by using power electronic devices such
as IGBTs to achieve speed control higher capacity industrial motors.

This study aimed to non-invasively detect electromyography (EMG) activity of deep thumb muscles using surface electrodes. Researchers placed electrodes on the forearms of 15 participants and recorded EMG signals while participants performed thumb movements. Independent component analysis was used to separate EMG signals from superficial and deep muscles. Predicted EMG waveforms for each deep muscle were correlated with independent components, and the highest correlated component was considered to represent that muscle's activity. Overall high correlations were found between predicted and recorded waveforms. Accuracy, sensitivity and specificity measures between predicted and recorded waveforms were also statistically significant when using a threshold activation level, demonstrating the first non-invasive detection of EMG activity from deep thumb muscles.
Presentation bipolar stepper motor driver circuitSarah Krystelle
This document describes a bipolar stepper motor driver circuit. The circuit uses three ICs - an LM555 timer, a 74LS194 shift register, and an L293D H-bridge motor driver. The LM555 produces clock pulses that shift the output of the 74LS194 either up or down, determining the direction of motor rotation. The 74LS194 outputs are fed to the L293D to drive the stepper motor windings forward or reverse based on the input. A potentiometer controls the motor speed and a switch selects the direction.
This circuit uses a D-type flip-flop as a priority encoder to determine which of eight switches is pressed first, lighting the corresponding LED and sounding a buzzer. When multiple switches are pressed simultaneously, it registers the first. The design could be expanded to indicate the order of multiple simultaneous button presses using a display. It requires common electronic components like resistors, capacitors, transistors, an LED array, buttons, and a buzzer.

Quizz buzzer by DIVYA S
1. 8 CANDITATE QUIZZ BUZZERS
ABSTRACT:
The quiz buzzer systems are widely used in school, colleges and
TV programs. The team which presses the buzzer earliest is entitled to
give the answer. At times it becomes very difficult to identify which
team has pressed the button when two teams press the buzzer within a
very small time gap. In such cases the decision can be biased due to
human intervention. The quiz buzzer presented here takes care of the
aforesaid problem. This quiz buzzer disables the other inputs as soon
as the first buzzer is pressed. This quiz buzzer can be used for a
maximum of eight teams. It is build around pic (PERIPHERAL
INTERFACE CONTROLLER) microcontroller.
In the buzzer round of quiz contests, the question is thrown
open to all the teams. The person who knows the answer hits the
buzzer first and then answers the question. Sometimes two or more
players hit the buzzer almost simultaneously and it is very difficult to
detect which of them has pressed the buzzer first. In television shows,
where the whole event is recorded, the actions are replayed in slow
motion to detect the first hit. Such slow motions are possible only
where huge funds are available to conduct the show.
For this reason buzzer rounds are avoided for quiz contests held in
colleges. This project is an electronic quiz buzzer that is affordable by
the colleges and even individuals. This project is useful for an 8-team
quiz contest, although it can be modified for more number of teams.
This system is sensitive. The circuit can detect and record the first hit
contestant among all the contestants that may appear to be
simultaneous. This project not only monitors the fastest finger, but
also evaluates the performance of the contestants by saving marks of
all participants in microcontroller registers as per Quiz Masters
guidance.
2. WORKING:
This project uses PIC 16F877A microcontroller. Quiz master
can justify the answer by incrementing / decrementing the marks of
particular team. Finally the quiz master can close the contest and he
can display the marks obtain by individual teams and winner details.
Once the hit of a team is registered, all the buttons are automatically
disabled. Even if any contestant tries to press the answer switch, the
system will not respond. A buzzer is provided for audio indication of
the switch bounce. Whenever a switch is bounced for answering, the
system acknowledges the fastest bounced switch by a short beep
sound. This buzzer possesses the timing about 1.30 sec (1500 ms).
This project uses regulated 9V battery. The stretch is connected
on port B, and the LED is connected to the port D. To check first
buzzer bounces while condition is used.
