I just came on here to ask for advice on a long range rf transmitter, although my intent is different to the original poster, I didn't think it made sense for me to make a new thread.
All I want to do is be able to transmit simple data 2km+ away to a matching receiver.
I've been looking at...
funny you bring this up, ive been planning on building some led lightning and the way id be wiring them i would not have to use a buck boost and i would keep my efficiency as high as possible if i wired them all in series, but then if one of them burns out i would have to test every one...
way to insult the only guy trying to help you.
why dont you just make a dc-dc converter that does 5V @ 270mA? you could also use a attiny and a transistor to set a timer.
if your knowledge of electronics is good enough.
Any links or suggestions? The only bucks I've "designed" are using national semiconductors web bench, and they don't seem to have a solution for what I need.
is there such thing as a regulator that can handle around 150V DC?
preferably a buck converter, not something that just turns the extra energy into heat.
ive been searching, but all the ones im finding are 80V input max.
Doing this in multisim, using a rectifier and a 1uF cap, the oscilloscope shows the voltage "smoothed" to 147-150, but a virtual probe shows it still spiking between 3V-150....
interesting.
last week I was checking the voltages of our vacuum which has some issues, and i measured the power coming in and it was 111VAC.
Our house is pretty far out, partially in the woods, and its an old house.
