J1772 is significantly more than a single resistor. And, while the signaling is analog, all practical implementations are going to use digital circuitry to generate and detect it.

I suspect (didn't watch) it's just that a diode makes a crude MPPT tracker (since a PV array is just a bunch diodes arranged to collect photons at the P-N junctions). The benchmark is probably "non-variable resistor".

TL;DW: Isn't that just because the diode matches the PV array's max power point, assuming they both use the same technology (e.g., silicon)? It seems like that depends on the diode string and PV array remaining at approximately th

Theory and practice and all that, but that shouldn’t happen regardless. A correctly-designed Ethernet interface is galvanically isolated at both ends to avoid ground loops, differing grounds, and other nasties over long distances.

Yes, but you do need a few really good senior people. If your salary table has a hard cap at 150k (and no equity to make up for it), you can’t hire those people. You also have a hard time hiring good mid-levels because you can’t possibly pa

It’s not how much they spent, but how they spent it. Their CEO was bragging about how many SWEs they were hiring. Quick question for HN: Would you rather work with 1000 mediocre SWEs or 10 really really good ones?

e-Trons are definitely among the best deals right now in used EVs, but it's down to a confluence of factors specific to that car: 1. It had fairly good charging, but only so-so range. 250 miles seems to be a big psychological barrier f

The reality is that there's no margin in cheap cars. You need to look at numbers instead of vibes. The difference between 4 crank-up window regulators and 4 power window regulators is less than $100. 4 power lock actuators cost less th

No idea if anyone actually does this. In theory, you could forward-bias the panels with an external power supply. That should generate infrared light at the band gap, which should melt the snow. It might be enough to just form a thin layer
