I'm looking for a source of like ~100 UWB-only ones aiming for about 2~3 weeks of battery runtime on a pack of 2~3 AA batteries. Mostly depends on what voltage end the chips handle better: 2V low end, or 4.5V high end. The aim is to ke

Unless you want individually addressable LEDs, the answer to the "if I can" is "yes".

Sure, adding that functionality to NVMe would be easy; there are sufficient provisions around for adding such support. E.g. for example a global flag who's support is communicated and which can then be turned on by the host to cause th

Either you ask a manufacturer like WD, or you go to ebay AFAIK. That said, ZNS is actually something specifically about being able to extract more value out of the same hardware (as the firmware no longer causes write amplification behind y

1) It's actually not that good, sadly. 2) It's not up that early, as it depends on much of the networking to be set up before the WiFi works. The UWB system would be set up in around 1-2 hours just walking around with a load of wa

I wish someone would sell an SSD that was at most a firmware update away between regular NVMe drive and ZNS NVMe drive. The latter just doesn't leave much room for the firmware to be clever and just swallow data. Maybe also add a pSLC

NVMe has no barrier that doesn't flush the pipeline/ringbuffer of IO requests submitted to it :(

Just get modules or strip from Yuju; I have zero bad experience over many years with them. Sure, it's not cheap, but IMO ~1$/W plus simple PSU (either some standard voltage, or dimmable current, depending on what you got) for good

Yeah, central Europe, probably also Eastern, just stay out of River banks or build with sufficient foundations, debris-catchers, and nothing vulnerable below the first above-ground floor. Yes, this includes making sure the interior walls do

I'm looking at setting up a trial system for 39c3 to allow hunting down tools given out from the logistics department (pallet jacks, ladders, if cheap enough pallets that get left unattended). Timeline for that is 10-11 months from now

Use one that has the "240VDC (China only)" rating, and feed them proper DC. Or get the modern western ~300V DC input ones, there's no good (technical) reason to feed AC from a non-grid-tie inverter to a SMPS-only circuit. The

That rail initially had a concession for 15 km/h. And I was pretty sure it ran up to 60 these days? Also, boring is good. Though do not be fooled by the hidden g-forces: the tilting behavior turns the side ways forces into just you bei

US DECT is 2.4 GHz, EU DECT has dedicated spectrum. Also, roaming works butter smooth. It's what's used often to provide cordless phone coverage to hospitals, for example.

Then get your calendar entries for 39c3 and subscribe to the relevant information channels to be notified of when those details have been worked out.

Until very recently YouTube did not support multiple user-choice audio tracks on a video, so they would have needed to be uploaded separately. Maybe it will change this year, though!

There is affordable accomodation: nearby gymnasiums where you bring a "bed" and "duvet" and "towel+shampoo" and get by with like 5 bucks a night.

I just checked; they do in fact upload the live dub audio streams, see this talk from last year which was given in English but this is the German dub: https://media.ccc.de/v/37c3-12340-37c3_infrastructure_review...

Notably the system works for substantially larger swinging angles (the structure gets somewhat heavier to leave that much more free space), and one could bank the track in turns, too. Together some impressive g forces could be archived; 1 h

That's called a second dishwasher: one is for taking out, the other for putting in. When the latter is full, turn it on, dirty dishes wait outside until the cycle finishes, when the dishwashers switch roles.

SiGe scales down, but we can't afford the power density resulting from building logic with it, so it ends up loosing to CMOS.
