Crap, you think you were confused - HELP! Reality check for me at this point. I was looking at the adapters from Sparfun then it dawned on me - I am running...
My experience with dc motors on rectified mains has been mostly with compound wound motors. I suspect that most pm motors are made for smooth (relatively so)...
How do the commercial devices harvesting low grade power sources work? Piezoelectric effect is used in some that I know of and magnetos such as discussed are...
If you have a digital multimeter with a capacitor meter function or a capacitance meter itself you can read the capacitance of the cable from each end....
By far the easiest way is to buy a treadmill motor driver. for $30 to $50 you get to connect the driver to 230 VAC and to the motor directly. a pot for speed...
... Well, you certainly need wide traces on both the top and bottom layers. ... That's the way I see it. The current conduction path is INSIDE the package....
Hi, ... why? ... As the datasheet said, you can use a zener, diode, resistor, or nothing. The IC has internal snubber diodes that clamp back EMF to a diode...
I suspect they work by doing a better job of matching the number of turns to the voltage required. We've discussed here before just how insanely inefficient...
Jon: Many thanks for the reply and advice. I do have a Digital Multimeter with the capability of testing Capacitance. A couple of quick questions and an issue...
Good morning (afternoon?) list: I have a question involving the distribution of power over several thousand feet in an outdoor setting. This is to support a...
120V x sqrt2 - 1.4V = 168V So if you can use 93.3% of the rated voltage, that should be good. You could also get an isolation transformer with taps to change...
... Vista - ... But... Microchip sells it! Wait, by "it" you mean Vista... MPLab works in Vista, so if PICKit 2 looks like a PICStart Plus to the computer, it...

... thousand ... 7.5" ... 100ma to ... 2,500' ... Sounds like a cool project, and fun with trains. A switching power supply looks the best way to go to me. ...
I filled up all the PCI slots with serial port cards in my lab PC at work, but the resulting 8 ports still weren't enough so i bought 4 USB/RS232 converters. ...
It's hard to believe, but yes, it's meant to take 30A continously. Well, perhaps by using the PCB traces as heatsinking too, so don't let the traces do all...
First check to see if it is a break or the light burned out. Take the collar close to the fence and see if it beeps Then if it is a break, look for places...
Hi Dennis, ... manufactured ... What kind of wire/cable is used? A TDR (Time Domain Reflectometer) is the traditional way to find shorts/opens in cables that...
... Well, that's the approach that I'd take. A 2.5W dissipation in one of those isn't really any big deal. If it's too much, then you should try a somewhat...
... There. I fixed that for ya... :-) -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of...
Oh boy, this is going to be a fun one to let the smoke out of :-) I do have some heavy PCB stock here. I will try to pick off a bit of copper to measure its...
It sure is amazing to think that all this current can pass not only through the chip, but also the traces! I can't help but try to compare it all to house...
... Neat! I guess that would answer my "How the heck much cable is there on this spool anyway?" question... I'm not real clear on why exactly he specifies that...
... Mitch: Thanks for the advice. I did to check if there is an actual break in the line by testing for an open/short situation and the indication ii its a...
HTH: I do have an oscilloscope and willing to do the DIY route if possible. Not sure exactly which cable was used by my supplier. The Milltronics site suggests...
sure thing, Transistors are made of silicon and some dopped sollution of germanimum, with this, silicon and some materials in it are sensitive to light. if...
