Lattice buying AMI is not an acquisition I anticipated what so ever. I feel like I either don't fully understand Lattice business or what AMI does beyond reference firmware.
E: Watched an interview, sounds like they wanna get bigger in the root of trust and security space? Still kinda odd but makes vaguely more sense now
Wiring new controller into my old folding eBike
Anyone have recommendations for a multi channel (4ch+) energy analyzer? Think Joulescope but does not need to have that precision or bandwidth, something in the Nordic PPK2 class is perfectly fine.
Ideally fully isolated frontend and good software for realtime PC side capture of data.
I want to avoid using an Oscilloscope because big and usually very cumbersome to setup with software and shunt etc
Ease of use and quick measurement setup is most important.
Is there any option to hire a bicycle for #emfcamp ?
It doesn't seem like there are any local companies that do that. I just want to get around a bit quicker than on foot and not be fully reliant on the shuttle service.

@G33KatWork@infosec.exchange it only gets as cold as the air output of the actual AC at best, there is mild condensation occasionally but does not really matter
Pleased to report that a tiny PC water cooling pump can easily deal with a 24 meter long loop to cool every room of your apartment with your mobile AC

@Hasitier@mastodon.social that is larger than this one but good to know there are 100W options in that ballpark
This is 65W?! Its hard to properly show how tiny this is. That thing can power my Laptops full throttle without issue.
I kinda forgot to actually announce this but I am, since beginning of the year, Vice President at @oshwassociation@mastodon.social
Am hoping to find more ways for OSHWA to support the open hardware community.
You can help by coming to our Summit in Berlin in May, its great fun and you will meet awesome people!
In 2 weeks the Open Hardware Summit is happening in Berlin from 23.-24.05!
It's a really fun crowd of people from the hardware world and you should totally come!
Tickets are still available but if you want a swag bag you better be quick:

@dlharmon@chaos.social ah ok yea parts in that realm are tough. Low performance stuff like MCUs are no issue but anything in that class that would pair with DDR4/5 is bad rn, there I would wait but worth developing right now, this is unlikely to last more than another year, getting to manufacturing stage always takes longer than usually expected

@dlharmon@chaos.social If your product doesn't involve high end flash and ram its pretty fine atm.
The US situation been fuckey since the first round of tariffs back in 2020 or so.
I'd say just go for it of you got an idea.

Is this just a dumb cash grab again that will heavily cost the smallest companies while the big bois can continue as usual?

Uhm.. wtf?! What is the plan here, to just completely deprive your own country of electronics?
There is not even remotely enough capacity in the US for testing and bringing up test labs takes a long time. Let alone the gigantic cost difference.

@Natasha_Jay @SaveTheOkapi Yes it uses a CNN model trained specifically for this. The tracking model was developed by Kyle McDonald for the 2020 Olympics.
There is a paper on it: https://dl.acm.org/doi/10.1145/3478511.3491310

@tnt @wren6991 If Pi can't help, CSDN has a couple listings. This one seems most promising if you feel like paying the vultures a few bucks. There are a few cheaper ones for 50 points that have 127 pages which is different from this preliminary PDF.

@whitequark@social.treehouse.systems
@whitequark hm, maybe I missed out on those efforts then. I only seen many failed proposal, maybe I need to dig deeper again to see what has been happening.
Replying to
@timonsku@mastodon.social
@whitequark Which, fair for the financial burden but the technical ground work needs to be more foundational to make package management a more natural first party aspect of Python, which I think we discussed before and realize is not straight forward but still think can see significant improvement over the current state.
Replying to
@whitequark@social.treehouse.systems
@whitequark Yea that is fair.
My issue is less with OpenAI specifically and more that ultimate control for cruicial infrastructure is in the hands of an unreliable actor. A neutral foundation is always an important layer of protection.
More a critique of governance.
I also have not really seen any desire by CPython to even start tackling this, irrespective of the available funds to realize the project. It was consistently pushed off to be "solved by community"
And another reason why Python packaging needs to gets fixed upstream. You can't have the languages package management be treated as a thing to be implemented by third parties.
Please CPython, finally learn from node and Rust on how to do this properly.

@gsuberland @wren6991 @alvaro I wish the industry took more care into adopting cmsis-dap+pack. J-link still the least headache for many parts unfortunately. Maybe there needs to be an org vendors can throw money at to add support for their part like they do with Segger.
Quite a few shoddy half done cmsis packs/svd files out there
Replying to
@mifune@mastodon.social
@mifune @wren6991 @alvaro my theory is that they are separate pins because they are easiest/best to short on the PCB. You need the pads in the connector for rotational symmetry and having them be individual pads happens by default due to how the construction works. Shorting them in the connector is rather complex manufacturing wise/an additional step and you can't do it in the cable without extra cables or creating an excessive stub via the plug+connector

@wren6991 @alvaro I feel like the type of person too lazy to read a spec in detail (most people really) would just google how to implement USB-C and use the first vaguely reliable looking circuit.
You need to be a weird type of half assing person to want to not do the lazy google route, read the spec but then not fully read the spec to actually implement it correctly :D

@wren6991 @alvaro yea smells like 2x10K parallel being on purpose to save the extra reel and they only ever intended to short the CC lines together.
Wild to still see this error being made 10y into USB-C adoption, really wonder where that comes from, there gotta be some wrong guidance around this somewhere.

@timonsku@mastodon.social
Ah its a zero, yea then def. nothing critical. On Pi5 I'm not as certain with RP1.
HDMI also needs the 5V for the EDID but that will be fine at 4V too.
Replying to
@gsuberland@chaos.social
Yea, like 99% certain 5V only powers the regulators and the USB ports.
