Hi all, I've got this capacitor with a rating of 5200uf and 64WV. What does WV means? wave volts? But how does this converts to Volts. Thanks, Davin...
Dear Group: This may be a stupid suggestion, but what if one were to install optoisloators on the cable line? This would short-circuit (literally and ...
Working voltage. This is the maximum voltage at which the capacitor operates without leaking excessively or arcing through. ken ============= Hi all, I've got...
somebody with experience with video signals can probably answer, as I have NO knowledge in this area........but I think that the signal coming over your cable...
Alien Steve The flyback has a ferrite core going down the middle of the windings and extending outside to form a large 0. This large 0 is made with a split...
... Install them how? A typical opto will require at least several millamps of current to make the input side of it do anything useful -- that's DC. A typical...
Just recieved ten Piezo film sensors (LDT0-028K from Measurement Specialties, Digikey part # MSP1006-ND. <$2 each! The basic idea behind getting these is...
Hi everybody I just joined up yesterday. I am also interested in home built lasers in the cutting and engraving application. My other passion is woodworking. I...
Thank you so much for the recommendation. That sounds like a lot of fun! Great for a high-impedance/high voltage load :) Best, Scotty ... From: ghidera2000 ...
Hi All.. I would like to know if its possible to convert a PARRALLEL signal
from a LPT port from my PC to Serial. The application is that I have a program that...

Hi all! Have two keyboards and two mice and need to connect them all to a pc running XP. No problem with the mice, the second goes on the com port with no ...
Done... Sorry for wasting your reading time, but i didn't expect it to work so easy. i simply used 4 diodes, allowing the keyboards to pull the lines low but ...
4 doides huh? Personally, I would have used a PIC and 6 open collector driver transistors, used a day to programme it to split the signal from the PC to both...

... Yes. ... Probably fine for your purpose. I would not put it back in a TV or monitor and expect it to work, but for experimenting with high voltage you...
figured the POST & windows problem out... Peter, put away the pic and get two npn transistors (or fets). the original four diodes, two transistors, and two...
Hi all, I'm in the US and am looking for a simple SPDT switch. Digi-key want $6.22 for one switch. It seems that a simple switch should not cost so darn much....
you didn't say what its for. power or signal? what's the minimum rating? push button? rocker? slide? pcb or panel mount? Mouser has 80 pages of switches....
first no question is stupid and second most cable convertors use radio frequency signals the opto's would just disconect the unit the convertors actualy use...
Stefan, I was about to write to tell you how much better my PIC idea is because it would light up LEDs on both keyboards - and then I read that one is...

The file uploaded <http://groups.yahoo.com/group/Electronics_101/files/Stefan_Trethan/> is the schematic. It works without any complaints... I don't really use...
Thanks Stefan. That's a neat little circuit and not a PIC in sight. I happen to have a project in mind that will use a simulated keyboard input to control a...
Dave, I've used an RCA plug for 12 Volt power off of a sealed lead acid battery, to run a telescope motor. It hasn't given me any trouble that I know of, and...

You want to charge a 12V (BIG) battery from a 12V weak system, right? well if the weak sytem already has a voltage regulator then you simply need to limit the...
