Abstract. Nowadays, the exercise culture at night among Malaysian has become a trend because
during the day it has been filled with work. Safety aspects need to be emphasized especially for those
who choose to workout outdoors due to low visibility level. Therefore, Firefly Headband Using
Piezoelectric for Night Workout is proposed in this paper as a safety gear for people who run at night.
This tool works based on a piezoelectric concept where it produces a voltage when mechanical pressure
is applied. The RF transmitter will be activated when the pressure is applied to the shoe and a voltage
of 8V will be generated. When the RF transmitter is activated, the RF receiver will be switched on and
the LED strap on the head will light up. Both RF transmitter and RF Receiver are operating wirelessly
for user comfort. Hopefully with this tool the risk of accidents can be reduced among those who do
exercise activities at night.

Abstract. In this era of globalization, our society has become less concerned about the importance of
exercise activities. Symptoms of obesity are increasing over the years because of the less concerned
of exercise activities. Most people in our country spend most of their time playing in the playground
because they can spend time with their children. In the playground there are exercise equipment
including exercise bikes. The hybrid solar bike project was built by modifying the used of the exercise
bike which is built using a charger and an inverter circuit. Hybrid solar bike combines the use of solar
energy as well as the gear and generator to charge the battery .This hybrid solar bike has been built to
make easier for users to use exercise bikes and at the same time users can charge electronic devices
such as phones, power bank , laptops and so on. Furthermore, with the production of this project,
electricity consumption can be reduced because the project is more towards green technology. Green
technology refers to the development and application of products, equipment and systems to maintain
the environment and to reduce the negative effects of human activities. The project consists of three
parts, which is the first part is the input part consist of a bicycle , generator , solar, battery, second part
converting direct current (DC) to the alternating current (AC) and the last part is output part which is
consist of a socket plug. In the output part there is also a meter to display the volume of voltage from
the battery. This project is used to save electricity costs because the bike only use the energy from the
user and the bike is also connected to generator and solar energy to produce electricity.
