A dive into the tiny, silicon accelerometers and gyros in your phone
  • This guy’s channel is so awesome, glad to see it posted here. He has all kinds of cool tools that he built in his lab like a scanning electron microscope. His videos on atomic force microscopes and laser lithography are really fascinating as well, he is really great at explaining the concepts too, definitely recommend!

  • Which link/bookmark manger do you prefer, and why?
  • +1 for Raindrop, that app is amazing, I keep watching for a self-hosted version/alternative that is as good and they are getting closer. The killer feature for me is being able to highlight stuff and then when you visit the site again you see what you have highlighted (in addition to saving them elsewhere). I also pay for premium because it’s great, I don’t use a ton of the pro features either.

  • Synology not working in different subnet - please help
  • So if I understand this right you will need to change the network on the port attached to the synology in your UniFi configuration or set the vlan tag in the synology OS, I would do the former. It sounds like you just added a second network/vlan to the existing interface which means you actually created a trunk and are getting the old network untagged and the new network with vlan tags which the synology is dropping. Synology OS also doesn’t really support trunked ports through the UI (even though it does support a port that only uses a vlan tag) so it’s much easier to just leave them untagged.

  • Datadog has a security footgun
  • I mean sure but that’s a lot of words to say “I didn’t read the directions and no one caught it in a merge request review because no one else read the directions either.”

    Their documentation and examples are pretty easy to read and the site parameter is explained in the getting started guide and even linked from the readme for the JavaScript sdk, and in lots of sample configurations so I’m not sure how this made it into a release and then no one noticed the missing metrics for eleven days, sounds like lots of issues in that shop.

    The behavior of the sdk isn’t great but the proposed solution wouldn’t work because you can use custom endpoints for all of the components using endpoints on domains you own anyway.

  • Opinion: It's Time To Ditch 2.4GHz WI-FI
  • Well 5ghz requires more power, has less range, and needs its own antenna so for microcontrollers this makes it pretty pointless for devices that need range and low bandwidth for sending sensor updates, especially those that are battery powered. 5ghz can also have its own issues in cities if you have a lot of use of the DFS bands as well as being worse at traversing reinforced concrete.

    Also, a 2.4ghz radio can also sometimes support other things like zigbee, BT, and BLE which can be used for other functions.

    For what it’s worth, I have probably 50 WiFi devices and the majority of them are 2.4ghz sensors or switches and other low bandwidth tasks and I don’t have any issues, even when living in an apartment complex. If you are having issues you might need different hardware or more access points or something.

    Anyway, all that to say that 2.4ghz definitely still has a lot of utility today.

  • How do I fix these god-awful seams?
  • So I stared at this for a while, particularly the pattern of the seam, I have a few questions. What type of infill are you using? how many outer wall loops? How much infill overlap (or whatever it is called)?

    Also what happens if you rotate the part on the bed 90 degrees so the seam is on a different axis? Or maybe 45 degrees? This will make sure it’s not some sort of mechanical issue in one direct that shows up in this specific situation.

    I know that all seems random but those are what I would check hah.

  • Sometimes fewer walls are better
  • I think what that person is saying is that in your example the left part would probably be more durable because it is flexible and that the part on the right is less durable but more rigid, basically saying your result is expected and makes sense if you are wanting durability over rigidity.

    I think that the part that is unclear is that OP is using durability, rigidity, and strength as they are defined by material science not in common English and they way they differ in definition makes that comment make sense. I’m not a material scientist though so I could be wrong.

    I hope that is correct and makes sense hah!

  • How do you cope with ADHD?
  • I have found the best way to cope is to surround yourself with people that understand and help you out when you fall short. Easier said than done for sure and it hasn’t always been that way for me but at this point I have a bunch of ADHD friends so they all get it, and my wife saves me usually, she is the best at that hah. Other than that I have been just leaning into it lately, for example find a job that has a lot of tasks that work well with your brain, choose wisely.

    I also treat my attention as a privilege that I can give people and not something someone can demand. I don’t phrase it that way to be egotistical, it’s just that my attention and focus is fleeting sometimes as it is so I need to defend it in that way to have any at all. This is also harder said than done but it’s also not too difficult, most people are understanding when you say “can I get back to you in 30 min when I’m done with I am doing” or “let’s put time on the calendar to work on that tomorrow” it turns out.

    Along this same line I also treat notifications everywhere as an opt-in activity, everything gets denied and I only let the most important ones through focus modes (I have an iPhone) that I actually need to receive and this includes all phone calls on all mediums. The only people that get let through focus modes are those that understand the gravity of interruptions on my brain (well and my parents because they are great hah).

    Well that was longer than I thought it would be but the short version is that you have to try to construct a situation for yourself that works with your brain and not against it, and it’s a long journey but you have to keep iterating on it like you have been.

    I hope some of that helps!

  • Any tip for printing TPU?
  • Make sure your filament roller doesn’t have too much resistance as well. Since TPU stretches linearly way more than any other filament if it does have a lot of resistance then the extruder won’t be able to pull more filament until it overcomes that resistance and the stretch and it ends up physically thinning out the filament. Just a thought, hope it helps!

  • Blobbing on outside walls Bambu PETG Basic, drying issue?
  • I agree with the other poster, this is wild. It seems like It is limited to one axis so maybe it’s a slicer or printer bug. Does it do it if you print it out of PLA? PETG is cranky all around but I have never had it do something like that hah. Is this part online somewhere? I can try to slice it and see what happens on my x1, I’m curious now haha.

    ETA: you should also open a support ticket, they have great suggestions sometimes.

  • Not all kitties hate water
  • I recently got a kitten and he is all about water, he even climbs in the sink to drink water! I am going to have to get him a kiddie pool in the spring, including a photo for the cat tax, his name is Galileo!

  • Looking for a specific Blog post
  • Alright I’m not sure if this is the right place to ask either but if I were to guess it is s01e6 that they are referring to, I had forgotten about that show! It is really a great show from what I remember, especially that episode. Definitely worth a watch if you have not, I should watch it again.
