thanks for asking. I don't have a specific end application but I found zener/avalanche effects interesting from the perspective of being a compact source of high voltage/high power even if only briefly. One person told me the peak pulse voltage depends on the voltage of the source (maybe a 50 v...
I have some ideas for two completely different processes that could yield a refrigerator sized or even oven sized production process. It would not be good for mass production (slow speed) but would have a low entry cost and would be good for low numbers of samples. It would allow you to keep...
I heard you can do rf stuff cheaply on a circuit board by running extra traces along each side of a signal line that act as a waveguide. It does not make any sense to me. I was always taught that wave guides had to surround the signal line. Does anyone know anything about this? Does it work...
I'd like to build a cheap antenna with the following properties:
900 mhz to 2.4 ghz reception but more is better. I know thats asking a lot.
very directional
cheap.
any suggestions?
I thought about trying some sort of helical antenna but with log spaced windings in endfire mode and a soup can...
ok, sorry
IOIO is the name of a usb connected development board that lets you use a computer as a microcontroller. My thought is that coupled with an android device or raspberry pi you might be able to do some really cool stuff. But, I have never tried doing any sort of hacking with android...
I know they don't (or didn't 15 years ago) teach that it does, but they also don't teach that it does not (15 years ago). Is anyone up to date on this or care to experiment?
I know there are a few ways to do it, but because of the difficulty involved most people just shop it out. Has anyone here done it or know of any sites on the subject?
I heard they act like a zener except where a zener allows current to run and keeps a stable voltage in reverse bias, an avalanche will allow the voltage to run.
I'd like to make an am receiver that runs through the normal am spectrum all the way up to 200mhz. I understand there are not normally am transmissions through this portion of the spectrum. Can anyone supply a schematic or tell me how to modify an existing one (with a link to it)?
Oh, I'd like...
Can anyone confirm this?
Someone told me that I can run the output of a camera flash through an avalanche diode and the diode will produce a very brief pulse at a much (?) higher voltage and power though possibly burning out the diode in the process. I'm a little doubtful of this. It seems...
I'm talking thousands or tens of thousands of volts with the added complication of possible nanosecond pulse durations.
I'm just curious how you guys would go about getting an idea of relative output values.
Here is my thought, please comment.
I don't want to take a chance on burning out an...
