Bug Zapper Counter
How designed circuit works? When the battery is turned on, the high-frequency oscillator composed of the transistor Q2 and the step-up transformer T1 is energized using the 3V DC supply generating a high-frequency alternating current of about 18kHz, boosted by T1 to about 500V. This high voltage ranging at 500V is then further stepped up using a ladder network, which is made up of three 1N4007 Diodes, capacitors C2- C4. This network steps the T output to approximately three times its original value and we get around 1500V which gets stored inside a high voltage PPC capacitor positioned at the extreme end of the ladder network. Now for bug counter purpose, I am sensing the voltage on the output cap, I added a few diodes D1-D3 on the bottom side so that you see a high to low transition when a bug is zapped. This works only if the output cap is fully discharged when a bug is zapped, which is unlikely. Worth a try if you have some diodes around, and a fair amount of bugs too. Further, Arduino nano is used to count these output from the diode, and display on an LCD.

Autonomous "Follow Me" Cooler
An Arduino Uno powers this autonomous “follow me” cooler that connects to a smartphone via Bluetooth and uses GPS to navigate. The robot cooler connects to a smartphone via Bluetooth and uses GPS to navigate. All the electronics will be contained in the base so that other objects can be carried as well. The electronics were installed in the box cutout under the platform. An Arduino Uno and a 5v battery to power the sensors, Bluetooth, and control logic. A 3s LiPo battery was used to power the motors. A HC-05 Bluetooth module was mounted at the front of the platform for better range. The rest of the components including a L298N motor driver, PAM-7Q GPS, and HMC6883L compass were mounted inside and connected to the Arduino through the breadboard. The compass works with I2C, so we connected the SLC and SDA pins to A5 and A4 respectively. The rest of the pins were connected through digital I/O.
