This is minor one, but annoys me how comnmon this is: light is made out of litle packets of energy called photons.
Here is a good video on the topic: youtube.com/watch?v=SDtAh9IwG-I (Too lazy didn’t watch: Light is an electromagnetc wave and is is not quantized. Only the interactions between atoms and light are quantized)
cdparanoia is old but has always worked fine, even on crappy drives and damaged disks. Even many modern tools like cyanrip just use cdparanoia to do the actual ripping, just wrapping it in a new UI. You will need to convert the output with another tool, but this is quite easy. (For mp3 disks, just mount them and copy the files, no special tools needed)
Not yet, but their could be in the future. Best to ignore it and move on. Even if it is extremely unlikely to be prosecuted for this stuff, it has happened, so why risk it.
Just a blocking occilstor based on a 2N3904. I later found that adding a capacitor across the coil connected to the transistors emiter and operating it at resonance, greatly improves the power consumption. (30mA to 1mA)
In my experience a large 1.5v D cell works best, as the limiting factor is generally current not coil resistance, unless you wind thousands of turns of fine wire.
I greatly prefer the occasional original post with actuall engagement to a flood of reposts. If I want reddit posts, I will go on reddit (and also get comments and things like that). On a more meta level, the only way a community can gain and retain users is by offering unique content. If 99% of content is just content from Reddit (with missing comments), why should anyone bother to use Lemmy?
Subscribing to a comunity does not cost anything, very few people will leave a community because it is dead, but people will leave a community that spams their feed.
You could connect the LEDs in 5 strings of 6 parallel LEDs, each string with it’s own 100 ohm resistor. You will need a significant amount of voltage for that, at lest 7x the threshold voltage of the LEDs
