Increase LED rope brightness on small intervalsview story

http://forum.allaboutcircuits.com – Hi everyone! I'm new here and getting back into circuits. I'm working on an LED light organ. I attached the schematic, it's pretty simple. It hooks up to a 3.5mm audio input and flashes some LEDs when the bass in the song hits. I'm using LED strips from this website here for my lighting I've got it working just fine, with only one minor problem. (Embedded)

Whci 16x2 lcd's are compatible?view story

http://forum.allaboutcircuits.com – I am replacing an LCD that I fried from not lining up the jack with the pins properly and sending 5v down a signal cable.. It's labelled: CK66 UL94V-0 NAN YA PLASTICS CORP. I can find lots of 1602 lcds on ebay but they all seem to have 2 encoders on the back, where mine only has one. (Embedded)

Preamp/buffer for gaincloneview story

http://forum.allaboutcircuits.com – Hi, I'm about to start building my own LM3886 gainclone, only a few parts are yet to arrive. I'll use two 19.4v 6.2A transformers, and two LT1084 or LT1584 for regulation. Sources will be mainly computer and phone and my doubt is if I'll need any kind of preamp/buffer and how to implement volume adjustment, I've ordered a few OPA827, BUF634 and OPA2134PA just in case. Any thoughts are welcome. (Embedded)

LED series with dimmer?view story

http://forum.allaboutcircuits.com – So I'm not the best at all of this stuff and I don't understand circuits and all this electronics stuff nearly as much as a lot of the people I see posting in here so I figured I'd ask for help. I am pretty good at stringing together simple series of LEDs, but that's about the extent of what I can do. (Embedded)

ZigBee - is it worth to learn about?view story

http://forum.allaboutcircuits.com – I run across several posts and articles about ZigBee in the last weeks, so I started to read about it. Started to consider implementing a basic application to gain some familiarity. I would like to hear any comments, even if brief about actual usage of ZigBee. Simply put: is it worth? (Embedded)

capacitive touch multi-swipe to singleview story

http://forum.allaboutcircuits.com – Hi all. The title says it, but rather cryptically. Let me expound a bit... I have a guitar project, which has two momentary "physical" switches, which trigger an external unit for two different functions. These functions are essentially "use the next" or "use the previous".

audio popview story

http://forum.allaboutcircuits.com – I am working on a project dealing with bluetooth audio. The audio signal is good, however, when the bluetooth module senses that the music is paused, the bluetooth module will go into a standby mode. When this happens, there is a pop that happens. The pop also happens when you press play again, and the bluetooth module wakes up. Is there a way to filter this spike? (Embedded)

Freescale MC9S08QG8 microcontroller project helpview story

http://forum.allaboutcircuits.com – This semester I had my first microcontrollers class and cant seem to get enough of it. For the classes final project my professor gave each student the choice between 4 different projects. I decided that I wanted to go through and do them all for practice. The program that I am working on takes a string of ASCII characters and sends them over the SCI and converts it to morse code. (Embedded)

Synchronous Motor Help Needed!view story

http://forum.allaboutcircuits.com – I just stripped my broken microwave and got this handy dandy SM16F BY36P1A3 synchronous motor out of it. Now that I have the motor, I would very much like to use it to control a door lock. The issue is, while I can get the motor to move in either direction, the way it switches is seemingly random. Just whenever I flip my on/off switch it could either go CW or CCW. (Embedded)
