Not sure about feeding it DC instead of AC Theoretically, it shoud work, but the device might use the 50 or 60 Hz AC signal as a clock reference,...
Beautiful ! Just what I was looking for ! Thanks !
A friend of mine asked me to help with the following problem: He's got 3 TV's around the house, all wired to the TV cable through a splitter....
The middle terminal (also called the wiper terminal) is connected together with one of the side terminals to pin 8 of the IC and to one side of...
Another famous chip amp is the TDA8560, specifically designed for 12 V automotive applications:...
The funny thing is that I have a really old (5 years ?) APC Back-UPS 500 VA under my desk with a rocker power switch like the old AT cases had,...
Ok, thanks for the info, but then another question: Is there any other UPS model / manufacturer that will automatically restart when the power...
Does anyone know if an APC SmartUPS like this: http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SC620I will automatically...
When connecting resistors in series, the result is the sum of each resistor. Rser = R1 + R2 + ... + Rn The resulting resistor is higher than...
Also, what everyone (including me :wallbash: ) forgot to mention is that the ADSL Modem and router are only required if you have broadband...
Actually, here's a complete diagram of how I would do it: http://img73.echo.cx/my.php?image=retea4oi.jpg [IMG] There are also other...
I still don't understand why do you need a 4 port NIC ? If you want to set up wired connections between multiple computers, you need a Fast...
Can anyone recommend a software solution (preferably one that runs on Windows) for network speed testing / benchmarking ? I'm thinking about...
I have to build a network in a building from my student campus. I have 75 rooms to connect, 15 rooms on each floor, 5 floors total. The network...
That sounds a lot like a BASIC Stamp from Parallax ... The PIC microcontroller contains a BASIC programming language interpreter, you cannot...

This circuit works, but I think it is very inefficient, because it uses a linear series regulator (7805 or zenner diode)... If I were to...
If you want it in KWh, you have to specify for how long... A device using 112 W (= 0.112 KW) will use 0.112 KWh in 1 hour, 0.224 KWh in 2...
Check out this Color Organ revealed by a google search. Cool mod, btw, but I would go with a specialized VU-Meter circuit, like UAA180 (you...
Well there are about 50 VDC on a phone line when it is NOT in use. The ringing signal is also about 75 V AC, 25 Hz if I remember correctly. When...
