Twitter used to be a fantastic place to interact with other electronics hobbyist. Then it became the nazi bar and that was that. Every once in a while I go back out of morbid curiosity but the Following tab is barren and the For You tab is disgusting.
I found a place on Mastodon, but the critical mass just isn’t there.
It doesn’t help that many cool looking hobby projects are now just AI slop.
I use xitter and as long as you nudge the For You tab by clicking show less of this a bit and following the odd thing you like it becomes quite useable.
I don’t have solar panels but own a house with parking spot.
I use the PG&E EV2-A night tariff at home which is still 0.23 $/kWh, though the rate at work is only 0.14 $/kWh which I use as much as possible. I rarely use the superchargers (0.45$/kWh.) Let’s use the 0.23 value.
I drive 15k miles per year. At roughly 2.5 mi/kWh. That gives $1380 per year.
At 20 mi/gallon and $6/gallon, I’d pay $4500 per year. At today’s gas prices, the difference is IMO not marginal anymore. (That said, I didn’t buy the EV for the drive savings…)
For whatever reason, my wife’s car needs yearly scheduled dealership visits that always cost a few hundred. Meanwhile, my 5 year old EV has had none of that, other than one of those recalls that required a technician to park 15 minutes on our driveway to tighten some bolt (which my wife’s car also had, but it took another visit to the dealership.)
The depreciation thing is true, but I drive my cars into the ground anyway, so it’s not a factor for me.
That’s understating the importance of the error coding. The modulation scheme is almost a side show, it’s the modern error coding algorithms (LDPC or Turbo coding) that allows you to get arbitrary close to the Shannon limit.
Moonwalking with Einstein is a fun read. I started using some tricks in real life. One of the key premises is that humans are much better at remembering sensory things than abstract ones.
A good example is remembering names: when one’s name is “John Baker”, it is so much easier to remember by silently adding “the” in front of it.
We’re also very good at remembering salacious stuff. I tried constructing my own memory palace for a grocery shopping list that included cream cheese. If you mentally make Claudia Schiffer take a bath in cream cheese, you’ll never forget that. (I read the book at least 10 years ago and still haven’t…)
LMAO I don't want to even guess how long it would have taken me to do 2+2 here if this exchange hadn't already occured. Thanks!
I do something similar just not normally in the middle (e.g. "long john baker" and a mental image of someone baking ing long johns), maybe I should give middles more of a try.
