This is a simple lightsaber toy with some functionality. It incorporates a few addressable LEDs and an ATTiny85 μC. It can light in Red color and a Rainbow effect. When not in hand it lights off due to an IR sensor. The design can be found https://www.tinkercad.com/things/4PYDB91v022 (Tinkercad design, simulation and code) A few more details and the code can be found in https://github.com/gkapsid/HomeProjects/tree/main/SimpleLightSaber

A small ATTiny project that implements a decorative light. It features three plain colors and a rainbow effect. The brightness of each light can also be controled within certain limits. The project is an adaptation for ATTiny uC of similar projects created for Arduino UNO. More info can be found: https://github.com/gkapsid/HomeProjects/tree/main/FirstATTiny (where the Decorative light is mentioned). Tinkercad simulation: https://www.tinkercad.com/things/11Gc88x2S0x

This is a short video that displays the assembly of the Kitronik Rear Bike Light Project Kit. A few simple modifications were implemented. The red LEDs were replaced by white in order to be used as front light not rear. A switch that is not included was added to control the light operation. The PCB and the battery holder was placed in a box (not included). The implementation includes no ucontroller and thus no code. A few more details and the circuit schematics can be found in the following address:

Modified RC toy car. New Features 1) BT controlled by smart phone 2) Front and back lights (red) controlled by the app 3) Flash lights (back lights orange colored) 4) Horn 5) Obstacle detection - Stops and moves back when an obstacle is detected at certain distance. It was implemented in a compact PCB board. Three modules where used: 1) Arduino Nano 5V 2) BT module HC-06 3) SN754410NE IC for custom motor bridge It is powered by two 18650 4V2 batteries. They are recharged using a lithium battery charger installed in the car. An extra switch is used to connect the batteries in series during operation and in parallel during recharge.

An ESP8266-01 controlled Neopixel strand using the RemoteXY app. The ESP8266 is connected as a client in the local network. The light is controlled locally. The app was deveoloped using the RemoteXY service: https://remotexy.com/ More info, code and schematic in : https://github.com/gkapsid/HomeProjects/tree/main/romanceLights
