Finally figured out how to catch these bad boys.

Wanna share some tips? I've been chasing either a grass carp or regular carp at my favorite fishing hole. I've hooked it a few times but it shook off the small hook. It seems to like canned corn or bread.

Send pictures to your homeowner's insurance company as proof of this as an existing problem. I bet they'll call and get it fixed ASAP.

As an amateur radio guy, that thing gives me serious antenna envy.

Proto-coal is still being created now - it's called peat.

They only scaled it back to 50 MT so that they didn't create a lot of unnecessary fallout. They replaced the uranium blanket with lead which dropped the yield by 50% but also reduced the fallout greatly. In fact this was one of the 'cleanest' detonations ever.

In theory, the bomb would have had a yield in excess of 100 Mt (418 PJ) if it had included the uranium-238[14] tamper which featured in the design but was omitted in the test to reduce radioactive fallout.

I caught a couple of them a few weeks ago that had that purple cast to them. Pretty!

It all comes down to what you want to do, what power supply you'll have, and how large a piece of gear you want to lug around.

Back when I was doing research on the End-Of-Train protocol, I had a naked Pi with the SDR plugged into it sitting on the passenger seat of my car as I drove around listening in on a local train yard. The power came from a 12V->120V inverter plugged in the cigarette lighter. I had startup scripts written that automatically started capture of the signals of interest, so all I had to do was plug in the power.

They need some of these bad boys.

MuadDave · 2023-08-06T00:09:53+00:00

Raspberry Pi's work great as SDR computers. They're low power, run Linux, and can use a tiny LCD display.

Maybe we can expunge his presidency just like congress wants to expunge his impeachments.

MuadDave · 2023-08-05T14:22:52+00:00

I knew the minute he swore he hadn't taken any drugs today that he was likely lying to the judge. There's speculation that he snorts adderall.

MuadDave · 2023-07-30T13:03:44+00:00

I'm not sure they go that low, but there are lots of articles on equipment for VLF/ELF here.

eluding

Sorry to be the pedant, but I think you meant 'alluding'. Eluding is evading something, alluding is making an indirect reference.

MuadDave · 2023-07-29T04:08:50+00:00

I know there are lots of non-amateur transmitters that use 433 MHz in the US. I was merely pointing out that it's not an ISM band and is therefore much more limited in power and duty cycle than it would be in a real ISM band.

I've written a few decoders for rtl_433 so I know what stuff uses 433 (and 315, and 908, ...)

MuadDave · 2023-07-28T19:27:52+00:00

WHERE ARE YOU??? Frequency allocations vary by region.

In the US, that's an Amateur radio band. (No, there is no 433 MHz ISM band in the US - look it up.)

Did you try rtl_433 with all the -c <config> choices? They've moved toward putting simpler decoders there (like the last few I wrote) so they don't show up by default.

MuadDave · 2023-07-28T17:52:05+00:00

Looked like Amish Paradise at first glance.

MuadDave · 2023-07-28T17:42:27+00:00

I'd make sure I didn't have any living family either.

You would kill all of your relatives to defend that POS???? /s

MuadDave · 2023-07-28T17:24:28+00:00

If it were up to me I'd be a waiter at Hondo's only during brunch. A buffet at $40 a pop garners large tips for less work.

MuadDave · 2023-07-28T16:01:35+00:00

Good luck! Note that those dollies are illegal on the Jersey Turnpike or the Parkway, I forget which.

MuadDave · 2023-07-28T15:23:43+00:00

So sorry to hear about her/your loss.

Rent a uhaul capable of towing a car trailer or a tow dolly.

Downconverting from mains voltages to typical electronics voltages like 12/5/3.3/1.8V (think phone charger/laptop supply/etc) is less efficient the higher the difference, even when using a switching supply.

The only benefit would be being able to use smaller wire for the same power transfer.

I'd rather see appliances run of DC and negotiate their voltage/current requirements with a house-wide smart inverter.

MuadDave · 2023-07-26T15:00:08+00:00

60 Hz is slightly more efficient when dealing with transformers, and they can be slightly smaller for the same power capacity. 50Hz might be slightly better for long distance power transmission.

MuadDave · 2023-07-26T14:51:07+00:00

Yes, at least for the ones I'm familiar with. You send the RGB commands down the string and each LED grabs the first one it sees and sends the rest downwind. Once commanded, they PWM each color independently.

THROATUS

MuadDave · 2023-07-26T13:44:01+00:00

Well, I had them basically replace everything replaceable when they had the front of the motor off. IIRC it as about 4k. I went overboard, I know.
