I've been watching the Solder Smoke direct conversion receiver challenge build and thinking of maybe building it from parts I already have laying around... assuming I wind my own toroids. I haven't noticed anyone talking about antenna stuff. What is the deal here?

This is the principal video series primer: https://www.youtube.com/watch?v=rLjxU2rMeXw

It is also on hackaday too.

Is there some rule about antenna where a more specialized element is required at specific frequencies? I know I'm missing fundamental practical information here as the wave length for 7 MHz is around 43 meters. Even a quarter wave length would involve a house spanning wire. So what gives, what high school fundamental have I forgotten?

IMO we have had decades of iterative change and exploration, but no major shifts or innovations. Like there have been many takes on the sounds of a guitar, but when do we get to the age of distortion piano-ish thing but entirely different? It seems like most major cultural shifts come from the cauldron or crucible of hard times. We may be near such a nightmare, so what do our kids create from the ashes?

I figured one of y'all would just know seeing how ubiquitous the 6502 is. I'm not following any tutorial at the moment and it has been too long since I last mucked around in assembly. I have the programming manual but it is convoluted between the 6502 and 65C816 stuff.

I'm messing with the little Easy 6502 emulator (Flatpak/FlatHub). I want to nest a couple of loops. I should probably just use the stack, but I went down this rabbit hole and damn it I want to find the rabbit!

I want something like (crude):

define lineL $1000
define lineH $1001

LDA $00
STA $lineL
LDA $02
STA $lineH

Hopefully I have that endian right... So now I have a 2 byte word starting at address 0×1000 and loaded with 0x0200. I want to increment this value as a 16 bit variable up to 0x05FF. What I am struggling with is which addressing mode indexes like this or if this must be manually implemented (– which does not seem right to me).

I'll figure it out on my own in the next couple of hours regardless. It is more fun to chat and see the spectrum of knowledge here, or maybe not, either way, ya don't know if ya don't try. Skool me Woz

Other than yourself. obviously.

I'm curious about the cliché or obscure superlatives with no constraints other than the scope of impact; could be positive or negative in some contexts.

I'm looking into them. I know they advertised as being an open source competitor to the Broadcom chips in the Raspberry π. The Rπ only has a partial peripherals datasheet available.

As far as I know, no current hardware has documented tape outs or fab level process documentation. So do any of you know the level of total documentation for the RockChip stuff? Any comments on hardware? Any recommendations on dev boards, tablets, netbooks, bootloader or kernel stuff?

I mean working somewhere like Qualcomm or Microsoft when you care about FOSS, democracy, and the public commons, or a weapons manufacturer for a military that invades other countries and kills innocent people in their homes.

Also, is self empathy even a thing? Is self empathy distinct from self pity?

A master wood machinist, if ever there was such a thing.

I made a Crytex such as the one from Da Vinci Code, out of wood. This time I used aluminum as well as a metal lathe to produce parts that would have otherwise been too fragile for a customer.

One of my favorite rare-to-upload stuff - channels. She likes a type of classical music that resonates with me, and I like the way she composes the content, music, and voiceover, combined with clever approaches to problem solving and projects.

An hour spent commuting is 1/16th of your daily life, and that hour is by far the biggest risk to your life every day. You should be getting triple pay to ameliorate the hazard risk it represents.

As in theme park and water park, opposed to national park and public park.

It seems like a bottleneck in language that I am struggling to find a way around. I believe the word park is poisoned in embedding models and would like to test that theory but I'm at a loss. I tried my usual thesaurus, looking at translations, and at etymologies but it seems like the word has no effective alternate so far. It is a rather interesting conundrum beyond the scope of my application – how would you differentiate and specify what a place like Disneyland is, without ambiguity, when "park" is not a useful word? And no land is not specific enough to describe the place.

I have a few ideas and stuff I have tried but I really want to know your ideas.

I didn't know my history in regards to Sappho. It is worth a watch. Jessica is quite the character.
