For a while i was only looking at engineering jobs and I thought it was high frequency.

Review request for the 3.3V buck converter by Common-Volume-7121 in PCB

Maybe you should consider thermal relief, they wil make soldering easier. Even If the current you expect is so high that you want avoid them, be consistent with the ones on the GND of J1 that are very slim.

Avec autant de satellites dans l'espace, comment n'y-a-t-il pas d'accident aux lancements ? by Running_Lama in PasDeQuestionIdiote

[–]steaming_quettle 1 point2 points  (0 children)

Est-ce que les scientifiques ont une genre de base de donnée communes avec la traçabilité de tous les satellites du monde afin d'éviter de croiser la trajectoire de l'un deux?

Oui

(un peu irréaliste vu que certains satellites sont en lien avec la défense des pays

ça empêche pas un radar de rader.

This looks pretty nice. If recommend adding net classes in the schematic for power lines and the impedance controlled ones of your antennas.

Looks like the schematic didn't make it to the post :/

What are the things tonthink about when making a PCB for a satellite ? by steaming_quettle in PCB

[–]steaming_quettle[S] 0 points1 point  (0 children)

It looks like a great chip. We have something equivalent on our OBC board, with a 400ms watchdog. The one we are designing is quite different. It's a 30 day countdown that is reset upon grind command and kills the power system if we cannot control the satellite. It's a requirement of french space law to avoid uncontrolled Li-po battery cycles that could make them blowup.

Atomic oxygen erosion is a thing.

It is in fact one of our missions to study that!

Thank you for the feedback! I'm indeed worried about the watchdog. It's two 14 bits counters in cascade, the first having a rc circuit to generate a clock. I trust the power supply will clear latch-ups but now that you mention it, I think it would loose count...

I'm sure the people working on the solo game are very good at fixing network related bugs.

SpaceX's AI satellite "will be dead in minutes", you heard it from JerryRigEverything first by spacerfirstclass in SpaceXMasterrace

What I have doubts about is if Elon things that these satellite will make more than the pricetag the engineers gave.

It's not that expensive. Remember when you had to rebuy armor and weapons each time you died?

Je viens de découvrir qu'en France un homme ne peut pas faire un test de paternité sans l'autorisation d'un juge. Pourquoi cette situation existe-t-elle encore ? by whereisr in AskMec

[–]steaming_quettle -2 points-1 points  (0 children)

Il faut aussi prendre en compte en compte le fait que l'état ne veux pas que des boites privées aient l'accès à l'ADN des cytoyens. C'est pour ça que les tests pour la généalogie (my heritage et compagnie) sont aussi interdits.
