  That’s for a single one but at tens of MW even a bunch of satellites isn’t going to get solar panels to produce an appreciable amount of power.

  This video goes into the details of what kind of performance we can expect from the constellation

• ⁨Comment⁩ on ⁨They're Making Solar Panels... Work at Night.⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  No the observed power on the ground is on the order of mW/m².

  Comparable to moonlight and so far no one has classified that as a weapon.

  As always with these startups, be careful with what you believe:

  Indeed

  Are there any implementations of this out there or is this purely theoretical (at this point in time)?

• ⁨Comment⁩ on ⁨PCB Design Review Request: ESP32 Smart Relay Board⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  The main reason for splitting up the relays into two sets is that with 10A traces the connector pins would violate minimum separation distances. I would have to get even larger connectors. The ones in the design have 5 mm pitch.

  I’m assuming the original board also did this for the same reason although their board is set up for 8 motors split into sets of 4.

  I’ve also had some trouble sourcing a 10A fuse suited for inductive loads but I’m sure I could find one with some more time.

  The whole board is on its own house circuit fused with a 16A breaker.

  It is my understanding that the ULN2003A (U4 and U5) has integrated flyback diodes. From the datasheet:

  Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.

  Good call on that ground plane. I’ll scoot the relays a little bit to the right. That should resolve the issue.

  Thanks for your feedback! :)

  Apart from the visibility argument. With this kind of parking spot you have to leave the spot in the other direction than you came in. So you’ll only get the enhanced agility for one of the moves.

  Would you rather have more agility when getting into the tight parking spot or when leaving onto a larger street?

  Getting the configs to work with my personal devices was already a little finicky but doing that for nontechnical family members was starting to be a bit too much work for me.

  I’m hoping that Headscale will cut that down to pointing their app at the server and having them enter their username and password.

  Was running wireguard and am now in the process of changing over to Tailscale (Headscale).

  It uses wireguard for the actual connections but manages all the wireguard configs for you.
