In that article I wrote about how I used an Arduino to create an interface that would allow me to directly control my fireplaces from my home automation system. That solution worked great and I was successful in running two fireplaces from the single controller for a year

with no issues. What I didn`t like though was that the completed project was bulky and I wanted something much smaller that I could put under the fireplace, thus out of sight! To accomplish this, I decided to buy a couple of Model B Raspberry Pi`s to replace the Arduino. WARNING: Let me interject here that one should exercise EXTREME caution before deciding to implement any kind of automated home controls such as those I will outline below! If you`re not comfortable dealing with electrical circuits then STOP here. Also be aware that your fireplace is supplied with natural gas or propane and working with its components presents a hazard. If you don`t know what you`re doing STOP and hire a professional to help you. The first thing I did was set my DHCP server up to assign specific addresses to each Pi. These are the addresses that my HA system uses to trigger the on/off events. Start by installing Raspbian. My implementations will be headless so I chose not to run a desktop thus reducing a little bit of overhead. There are tons of install examples online so I won`t cover that here. Once complete, run: auto lo iface lo inet loopback iface eth0 inet dhcp #iface wlan0 inet manual auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wpa-ssid "yourSSID" wpa-psk "yourPASSWORD" iface default inet dhcp wpa-roam /etc/wpa_supplicant/wpa_supplicant. conf By default, Raspian will try to manage the adapter`s power use by putting it to...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
