Oh, so they can’t get autonomous driving to work, thus the next step is to get people who are sleeping to steer the cars remotely

Great, good luck with that :)
Another thing that comes to mind: for audio purposes another technique used in ring modulators for audio effects is to use a mosfet switch to mix the signal with a square wave. This has more byproducts than mixing with a pure sine, but is a lot easier to do. Since you are downconcerting, it should not matter at all if you use a square wave, since the byproducts will all be (higher-order) harmonics of the local oscillator, which you’ll filter out anyway.
I’m not sure I understand what you are trying to do… do you want to build a radio? Or are all your signals in the audio range?
Anyway:
Regarding Gilbert cells, the two popular chips are MC1496 and SA631. The 631 comes with a built-in oscillator, so it’s quite handy. Unfortunately both are hard to come by these days.
Sounds great, except i think this whole thing is about some punching game… Not sure though, i’m not a sports person
Heresy! Australia will always be a planet.
Damn, i was hoping for them to make it slower!
Growing plants with LEDs certainly works, I’m just wondering if the power of a USB port is enough
there’s no need for relays if you have low voltage
That’s a good point. Also makes me wonder if those lights will actually make a difference when it comes to plant growth, given the low power.
It’s not completely stupid. One pissible issue: when the light level is around the threshold, slight variations (think: cloud passing by) will cause the relay to switch back and forth quickly. This can be solved with some additional parts (keyword: hysteresis).
I would recommend using a microcontroller, it makes this problem easy to solve, plus you can have more logic to trigger the lights (eg time based).
Another thing is turning off: if it’s purely based on light level, you need to make sure the sensor does not “see” any of the LED light, otherwise it thinks the sun is back up
Sounds like gifting
I don’t get the joke… why did you post four identical pictures?
Please don’t feed bread to ducks, it gives them diarrhea
Someone is asking the important questions
It’s like if farmers were just letting plants do all the work, instead of manually assembling the potatoes themselves
Dude, that’s genius! What if we also attached a thousand motors that spin on each key you press and press a thousand other keys in turn?
If the electrical connections are still intact, you can use some glue or tape to stabilize it, to prevent it from breaking further.
To prevent it in the future: always pull cables out by the plug, never pull on the cable itself.
The cake is a lie

Is that a map they are standing on?
ISS, as in: you get shot into space?
