i despise plastic and i want to minimize it where possible.

in this particular case the components will be exposed to the sun and that will degrade the plastic over time, and that is something that wont happen to wood :)

diy qfh antenna (self.amateur_radio)
 

hello,

i want to make this antenna (check link) to get sat weather images sata with my sdr.

will it make a dofference if I replace.the plastic parts with wooden?

also is any other type of antenna more suitable for this purpose? (I want it to be as compact as possible because the only space i have available is on my flat's window)

I want to have it always plugged to the power and to an external speaker so I dont care about its battery life

some must haves:

  • aluminum
  • not more than 80£
  • reliable (ideally buy for life as muxh possible for tech)

good to have:

  • easily repairable
  • I can remove the battery

does this thing exist?

the x230 is great but the plastics are crumbling so I thought it is a good chance to get something with a better screen.

the framework feels cheap, even though it costs a lot, Im pretty sure it wont last for as long I bought it to last without the need for replacement parts.

 

im looking into replacing my current x230 and framework laptop with an old thinkpad.

my requirements are: great linux support, compact (as much it can), alum or metallic body.

good to have: boxy look, model after 2018, coreboot/libreboot (i doubt new models are supported but one can dream)

does this thing exists?

No but I rebooted the system after the change. do still need to update it regardless the reboot?

no, I just removed them with the live cd and repartitioned it (Im assuming its doing the same thing under the hood?)

editing the /etc/fstab didnt work (I just changed the path but not sure if the uuid plays any part) but ill give the rm/mkdir part a go

the command returns my user dir and a lost+found dir

Im giving a go fedora silverblue on a new laptop but Im unable to boot (and since im a linux noob the first thing i tried was installing it fresh again but that didnt resolve it).

its a single drive partitioned to ext4 and encrypted with luks (its basically the default config from the fedora installation)

any ideas for things to try?

 

Im in the process on building something similar with the rack you see in the picture.

What I want to know is if its possible to determine the optimal length of the tube on the frame and on the rack to allow the max load under stress without the rack breaking/bending on a spot that its not mounted on the frame, and what would be the max load?

and if it is, how to calculate it? :)

things that i know:

  • number of tubes
  • length
  • diameter
  • thickness
  • bending tube angle
  • stainless steel type

worth saying that this is more of a learning exercise.

do you encrypt them?

Im curious on why you are using zfs snapshots? (i never used them myself as I handle my backups with duplicity)

[–] evasync 3 points 5 months ago

exciting but def not for me :)

[–] evasync 1 points 5 months ago

i agree.. but Im trying to find out if the chances of this shit happening is lower with specific hdds

 

i want to buy a few hard drives for backups.

What is the most reliable option for longetivity? i was looking at the wd ae, which they claim is fit for this purpose, but knowing nothing about hard drives, I wouldnt know if it was a marketing claim..

I had no idea that cromoly tubes were so expensive so Im now looking for alternatives..

a generic question I have is, does it really matter on what I use of its not for a competition setup?

I mean I dnt care if its relatively heavy.. my initial thoughts was using stainless steel tubes or even construction rods but everyone online seem to recommend only using cromoly..

edit: ordered 5x25mm wtainless steel tubes for 15eur (1.5m) the same in cromoly couldnt find them under 70eur..

DIY true a wheel (self.bikewrench)
submitted 6 months ago* (last edited 6 months ago) by evasync to c/bikewrench
 

I had some wheel made but when they rotate they come in contact with the disc break pads (slightly).

The bikeshop that built them will take another month to look at this, as they are fully booked, and I dont want to pay 35+ on another bikeshop..

Is it doable to DIY this with a spoke key and using the fork as a stand?

(I think it would be a useful skill to learn as it will make me less dependent on bikeshops)

Any brands that sell a rack like the one in the picture? (Edit: what i like from this rack is the mounting points on the frame that will result in a more comfortable ride than carrying the weight on the handlebars or fork))

If not do you recommend someone that can make this without breaking the bank? (I grew up in an agricultural area and there were a lot of folks that could weld something like that for a small fee - but some people online are charging 300+ for this, which is insane)

diy bike assembling (self.bikewrench)
submitted 7 months ago by evasync to c/bikewrench
 

Bike shops are asking 100+£ for a bike assemble and it might be justified but its too much for my budget and I want to DIY it.

Is that risky to do by watching youtube videos and borrowing tools from friends?

I want to install an english threaded bottom branket with a squared tappered crankset, disc brakes (mechanical), headset (threadless including cutting stem).

presoldered air quality sensors (self.homeautomation)
submitted 7 months ago by evasync to c/homeautomation
 

Are there any individuals or services that will build a custom air quality sensor from individual components for a fee? I am mainly interested parties in a couple humidity+temp+co2 boxes (wifi,zigbee,zwave or cable)

(Airgradient is prob ideal but too expensive)
