- mk_stjamesGiven the reputation for the cost and provenance of the cameras I'm surprised that Hasselblad passed through QC with that solder spooge at the edge that got into the frame of the film. I mean... it's visible on all the photos. I'm surprised that someone didn't notice that in testing before the camera left and send it back. Hell, even if I bought a cheap camera today and every photo has a little unexposed notch in the edge I'd be pissed. If you told me a camera was going to the moon I'd think I'd want the frame to be flawless....
- The table lists F1 cars as having "Carbon fiber brake calipers".
This is glaringly incorrect. All current brake calipers are machined from aluminum, specifically Aluminum-Lithium or Aluminum-Copper alloys. There is a rule denoting bulk elasticity modulus limit on brake calipers of 80 GPa, which was set just at that to allow the more exotic Lithium Aluminum alloys but to dis-allow Titanium alloys or anything else stiffer (There was experimentation with Titanium calipers in the past.)
Absolutely no calipers are made from composites, CF, graphite, or otherwise. Discs are Carbon-carbon.
- So you're telling me that simply walking out to the car and hitting a button inside the car is just too much of an "inconvenient experience"?
You know we used to have to drive the car... sometimes many miles... to a station, get out, and fill it up with a liquid fuel that costs many times more, and then drive home...
Seriously now- The perceived 'inconvenience' you have is the reason that so many of these connected features are being pushed and then the because the ability is there the business types can't resist the data gathering that became possible because of all the antennas, etc.
- 7, if the Extremely Strong Goldbach Conjecture holds. [1]
- Really cool, I figured that was the case and I'd be in the same boat.
I have an ice40UP5k board but I quickly ran out of block ram and LUTS whenever trying to use it for anything substantial, but seeing this project has me itching to start something around one of these icesugar pro boards. yosys & nextpnr support made things really damn easy when I was working with the ice40.
- There is 32MB of SDRAM on the FPGA board.... I wonder exactly what using 1MB of that as the system memory would have entailed instead of the separate 1MB SRAM chip that had to be soldered. Was using the extra SRAM chip just done just to do it, or is there a specific reason there that I'm not seeing/understanding...
- Ever since 802.11ah devices started appearing I've thought it would be perfect for partnering inside wireless IP cameras... and hell, make them mesh together with something like this so each one configured on your network extends the range of the others in it's area. Streaming 720P H265 is easily doable at the speeds the networks achieve for a few cameras, and the range would be perfect for perimeter monitoring most properties ala farms & industrial parks.
This device however - an entire Raspberry Pi + hat for a router to do..? ... seems like a solution in search of a problem to solve.
- So, after seeing how cheap and available these Phomemo printers are and with this CUPS driver looking like a good option, my instinct as someone who also wants one of these sitting permanently on my home network as to appear all the time on all my machines' available printer options, is to get one and tether it permanently to a tiny linux SBC that has bluetooth and running the driver and print sharing. Like the OrangePi Zero 2w I have sitting unused in a drawer somewhere collecting dust.
- I was recently thinking about super deep drilling after coming across a very neat mini-documetary [0] self-filmed by a geophysicist around the work at the Kola superdeep borehole [1] in 1992.
It is project I had heard about before but only in bullshit-passing articles and scrolling past brain rot youtube videos (seriously, search 'Kola superdeep borehole' on youtube and take note of how absolutely trash every other thumbnail appears concerning what in reality is just a normal scientific endeavour). So this video by David Smythe of the actual work there was wonderful and also a nice little nostalgic look at science and research as filmed by a VHS camcorder in that era. The computer equipment stuggles, etc...
It left me wondering about new research in this area and surprised I had not heard of any other such projects recently, so this news in interesting.

- That didn't sound right to me, and so I checked it as follows:
Estimate for a standard classroom globe at 13" in diameter (I'm seeing a rnage of 12-14 inches as typical). I'm reporting in inches because that is what came up first and most of the globes are for sale in the US. Mixing units here, but, it works out.
But, in meters, the diameter of the Earth is 12,742,000 m on average. if we use the 'Karman line' as defining the edge of what the atmosphere is, that is 100,000 meters. Solving for X ... (13" / 12742000 m)=(X / 100,000 m). gives us an atmosphere thickness of approximately 0.1". -----
Paper glued to the globe would have a thickness of maybe, 0.004" (thin paper) to 0.012" (like a card stock paper).... so that analogy is off by an order of magnitude or more.
Even if you use the mesosphere as the definition for the top of the atmosphere, that is still 85,000 meters and thus similar.
People can check the numbers I used.
* Perhaps the analogy should go more like: the thickness of the cardboard sphere the globe is made out of is about the thickness of the atmosphere. Because, having completely destroyed a globe once in my youth, I remember the cardboard shell being approximately a tenth of an inch thick. But, that's maybe not a great reference for the analogy because not everyone has cut apart a classroom globe....
- The System on Module board is an Inforce 6601 SOM. [0]
It uses a Qualcomm Snapdragon 820 and they provide prebuilt Ubuntu Linaro distros for it, preconfigured for the board.
The camera manufacturer likely just tossed it straight in as configured and thus didn't know how the full disk encryption was setup.
This whole camera design looks like one of those 'we gave this project to some undergrad engineering students who've never designed a commercial product before and had no price target and thus it has a whole damn embedded linux system inside it for merely taking some HD video and stills triggered by some external wiring and saving them to an SD card'.

- Absolutely. I have a person favorite setup... which is to have these two playing at the * same time * and play around with the combos of sliders / set to automate.
Pair: https://mynoise.net/NoiseMachines/numberStationsRadioNoiseGe... with: https://mynoise.net/NoiseMachines/magicDuneArrakisGenerator....
I set the numbers stations to 'narrow' and Arrakis to 'wide' and stereo field, mute the numbers stations that repeats german numbers (those stand out to me too easily)... and it's like some magical productivity hack of my brain.
- 'Dinosaurs' was a masterpiece and I won't hear otherwise.
The series finale is one of the greatest T.V. finales of all time.
- What, not a fan of 'Cow tools'? [0]
- I was prepared to be absolutely fucking disgusted by such a comment but I.... shit. I mean... this is.... this is wild
I gotta go contemplate 'where we're at' again it seems. If that is truly a straight generative audio diffusion model.... wait, how did they get the same verse by verse chord progressions to match? this has to be professionally post-produced, right? AI models aren't able to do this end-to-end yet, right?
- I would argue that valuation of '50 Cent' (real name Curtis James Jackson III) was essentially flat leading up to immediately before the release of Get Rich or Die Tryin', his debut album released February 6, 2003.
Which, undeniable, is an * all-time banger * that substantially increased the valuation of 50 Cent to something far surpassing US dollar inflation.
Seriously, go listen that that album again; total game changer. Top cut: https://www.youtube.com/watch?v=5D3crqpClPY
- This isn't the greatest wikipedia article, but I'd rather not write more on a topic so close to heart....
https://en.wikipedia.org/wiki/Speedball_(drug)
That'll get you started.
- I don't see if they found out the pinouts for the SFP connectors on the back. If those were documented, and the PCI-e lanes were documented, I could see someone having some real fun with these building some bespoke fiber networking gear.
SFP transceivers are just that- transceivers, they will spit out what you put in, so you could even build some interesting bespoke fiber optic signaling gear with these, and a PCIe backplane, or just solo.
- They do this to measure load vs deflection and check agreement with models, not to get anywhere close to yield. It's a low end proof check, drive trucks on, measure deflections, drive trucks off, confirm reset of deflection;
The margin on actual load to a permanent set is likely 2-3x what those trucks are carrying. And the margin to actual failure from just this quasi static loading and no external environmental loads (wind)... even more so.
Unless there was some catastrophic fuck up in construction process or calculations, this is completely safe.
