A home automation microcontroller with speech recognition function so depends on what you say it turns on and off home appliances, lights, TV ..etc...Question: is it possible to modulate the on-off instruction signal on the mains supply wires so that you do not need to install a receiver on each appliance ? I know the answer is yes..the que
Hello, I have an adsl router at home (like most) and a small computer (mini server) connected to it. The computer is an Alix-1D and consumes only 5W max at 12V. I want to build a small UPS for these two, so that it can keep them up and running when power is lost. Mostly interested in sudden power loss, a few minutes max (which happens (...)
Hi all. Hopefully someone here can help advise me on this issue. I have an iPod/music player called a Bowers & Wilkins 'Zeppelin air' that stopped working a while ago. Zero power to the unit despite fuses and external supply being good. The power supply board in the unit is known to be the fault with these devices. So I removed the board to s
Need to know exact definition of following terms.. PMPO output, Source input, Frequency response, S/N ratio, Distortion, Output power, Separation, Input sensitive, Hum-noise output, Satellite impedance, Subwoofer impedance, power consumption, power supply SMPS Type, Satellite Dimension, Subwoofer Dimension
Hi - I purchased a ZVOX home theater 670 soundbar at a significantly reduced price due to an issue with it. When switching the unit on, it appears to complete a POST, displays the current firmware revision, and displays "ON". However, After this initial power-up which lasts about 2 seconds, the unit does not respond to any buttons. I'm think
Use more efficient 15" drivers and use a much lower power amp is the best solution..... I have 4 x 15" in my home stereo driven from a 60W amp, plenty of SPL, in fact it can go far too loud so why such a big amp.... I use 4 of these... 98.6dB 2.83V/m If I used 92.6dB 2.83V/m drivers I would have to use a 240W amp to get the same sound pressure out
I made homebrew circuits for my 24V backup home power system. Two solar panels in series can put out 46V when unloaded. My charge controller was built around an op amp which cannot endure such a high voltage. So I regulated its supply down to a safe volt level, with a zener diode and resistor. It worked. Perhaps a similar system is inside (...)
Hi I am using a triac and also a relay to control loads from a microcontroller. In the circuit shown both A and B are connected to microcontroller. The problem is, when the triac is in OFF state, if relay is used or any other switch in my home is operated, the bulb connected to the triac flashes once. Kindly tell the reason for this if anyone a

i am working on my project that switches off and ON home appliances using an android app that creats sms .The app can also request for power being drawn by the appliances through sending texts request that can be red by a gsm module. My gsm module is linked to a pic 18f4550 and my gsm module is a sim 300 gsm module. I am using a CTL6vz current se
many choices for make or buy depending on your skill. join ( free ) then use their selector on home page with input and output power specs. There are other sites, too. Linear, Maxim, ROhm, Toshiba etc or choose from a "disti" like Digikey, Mouser.
Hi all, I'm new to this forum and hope that you can help me. I'm in the process of building a control cabinet for my home brewery. The brewery consists of three heating elements (3500W) but I only have available two 16A power feeds (220V, living in Norway). The heating elements are controlled by 3 switches (SW1, SW2, SW3) and 4 contactors (
Hello, This program I founded in other web forum, then I try to a bit modification on the program. I got this idea, because I seen on my electronic device at home there are power button, the functioned same like this project. One times you press the button and power will lit then after you want to switch off the button you cant only (...)
even for yourself in your own home, you might appreciate PFC sunny, your post is the correct one. especially for a job interview Q&A ;)
do you want emergency lighting? This switches on , when electricity in home cuts off ?
Hi all, I'm looking to a Volt, Watt and Ammeter using a microcontroller to be used in a home made power supply that regulates the negative rail. The range must be 0-20V and 0-50A and of course 20*50=0-1.000W and if possible with labels in portuguese like Tensao for Volts, Corrente for the Ammeter and Potencia for Watts but other languages are we
I have a 12V to 230V/50Hz , 1000 Watt home Inverter whose circuit based on pic16f72. The AC output voltage is so high as 285V. Due to this high output voltage many appliances like CFL, LED lamps etc failing when running on inverter. How to reduce the output AC voltage of inverter?? Please give a solution.
This might help:
Hi, I am looking for a good inverter for my home in Chennai. My needs include four fans, one TV, and a fridge. I have a limited budget, but can increase the amount if the inverter is good.
I started a blog of home lighting using common wall powered LEDs using unregulated, regulated and modified adjustable Laptop Chargers. CREE 1~3W LEDs can be used in series to match the supply voltage and parallel arrays on a string of wire to distribute. Thermal runaway avoidance is satisfied but
