Arduino Fireworks controller

JonBush has posted great instructions on building an Arduino-powered firework controller. My module is Arduino powered for a few reasons. 1) I need to work on my programming skills. 2) I wanted it to be “smart” or “aware” of what connections were present. 3) I wanted to have control over timing adjustments that a more analog solution wouldn’t allow. 4) I wanted a more graphical user interface that would be fun for my kids. The complete solution was a two part module that allows you, children, babies, etc to safely enjoy launching fireworks from a minimum distance of 50 feet.

TIC-TAC TV Remote Jammer

DangerousTim’s TV remote jammer is disguised in a TicTac Box, which constantly sends steady IR pulses at about 40kHz to the TV receiver to disable any command sent from the TV remote. With this handy little circuit, you can watch your favorite show without any interruption from your family member.

IOT enabled AC wall outlet

Gopinath.Marappan has posted great instructions about how he built an IoT enabled AC wall outlet using Arduino and ESP8266 platforms, along with a bunch of sensors, relays, and LCD displays. It features light and fan On/Off control, fan speed regulator, mood lighting, and cloud datalogger. It also allows IR remote control, amartphone app control, twitter and SMS alerts, and many more features. This project was conceived when I felt the need to automatically reduce the speed of an AC ceiling fan in the bedroom as temperature drops through the night. In Bangalore, where I live, during winters, I like to

PIC18 development board with ethernet capability

DIY development boards are popular among hobbyists. [magkopian] from Greece has designed a PIC18 development board that features Ethernet connectivity (using ENC28J60) and Full Speed USB 2.0. The development board is based on a PIC18LF4553 microcontroller. The microcontroller features a Full Speed USB 2.0 (12Mbit/s) interface without the need for any external components. Also, it has 32KB of program memory, 2KB of RAM and it supports an external clock up to 48MHz, which is optional because it also has an 8MHz internal clock. The ENC28J60 Ethernet controller is used to provide Ethernet connectivity to the microcontroller thought the SPI interface.
