@EV_Trapper Pole-21 is not a radar, it is an EW system.

@aviationarchive One of them is in a museum in Ukraine.

@olegkutkov I usually recap all such equipment right after buying it. A lesson that RIFA taught me. Especially for “always on” equipment like this.

@0xSero GPUs will cook themselves but before they will fire CPU.

@photoncmndr The radio stack will be fully open but some kind signed? Because if it fully open it is hard to imagine a pre-certified module based on the chip. And each developer will need to certify each design for all target markets.

[Denys @karaporkin]

@__tinygrad__ Does it non compatible with old SXM? Like https://t.co/60mbIXa1te

@photoncmndr Once they are positive, you are good in 99.9% cases. For high-reliability applications, you still always need to physically test under different temperatures/voltage over a batch.

[Denys @karaporkin]

@blind_via I did the same. Most likely, it is debug connector. Once you build something that you certified for EMC or similar, you do not want or can’t to change any metal layers. So any unused features are simply covered with mask.

@paulg Progress not always linear or exponential.
Most likely, we will reach a plateau soon, and only the next breakthrough will lead to such progress.

@PalmerLuckey Designs failing during testing is actually fun. Anyone who’s designed anything meaningful has experienced it. If you haven’t, you probably haven’t designed much.

[Denys @karaporkin]

@boxcardavid Turns yes, but you can increase crossection or number of strands to improve filling factor - efficiency.

[Denys @karaporkin]

@tomfleet The outer holes help prevent delamination from screw torque by supporting the outside radius. Grouping them also creates rigid ribs, reducing board fragility and leaving useful paths for inner-layer routing.

@_Stocko_ If you haven't heard of Theo Jansen, I recommend checking out his designs. https://t.co/rWt0I7AApY

@Aaronia_AG Looks fascinating! What the system clock source PLL do you use to clock all these components with low phase noise?

[Denys @karaporkin]

@CooperZurad I feel the magic smell over the photo.

[Denys @karaporkin]

@boxcardavid @mattparlmer And magnets?

[Denys @karaporkin]

@0xSero He has nothing to do with freedom.

[Denys @karaporkin]

@__tinygrad__ There will be a severe temperature gradient between the boards if you plan to push air through all of them.

[Denys @karaporkin]

@Tri_Stanisaurus yes, dm?

[Denys @karaporkin]

@bubbleboi If you can pack this like HBM - yes, otherwise- no
