    1. Ideas for Arduino/microbits projects for my kids and me

      What projects would you think would interest my daughters the most? The oldest is 11 years, super creative and builds the most intricate stuff out of plain paper, tape and cardboard. I have learned programming from about her age, but feel like software would not catch her attention the same way hardware would. They already experiment with programming and microbits in school (what a truly lucky generation!!!).

      I am looking for stuff that is not too complicated/expensive that it will just collect dust on a shelf because it took a lot of time to build. Specifically I would like to try something that could be dismantled and reused for other projects. Maybe a barcode scanner or something that has a connection with real life applications.

      Some background here - I have a niche YouTube channel, mostly doing longform (often 3+ hour) commentaries on a board game with a friend. We're both very skilled at the game and are apparently entertaining to listen to, but it's all very amateur - I don't really know anything about videomaking except what I've picked up as I go.

      That had never really been an issue, because the topic is so niche that only people really interested in the game watch, and they didn't really mind. But last year we got a shout-out from a big YouTuber and the subscriber count has gone up a lot since, to the point where it feels like I really should figure out how to make it a little less amateurish.

      I want to start with audio, because that's 90% of what we do. But I don't even know where to start with it.

      I got Blue Yetis for both of us a few years ago because I was vaguely aware that was a good mic, but if anything it made it slightly worse than just using headsets (quite a bit more echoey) - I don't know if that was a mistake, and if there are better mics to go for?

      I'm also aware that you're supposed to have some kind of padding on the walls to stop the echoing, but that isn't really feasible for me both because I rent, and because all the rooms of the apartment I'm in are absolutely massive. I've heard that you can throw a blanket over your head, which I've tried for a short video but I absolutely couldn't handle for a three hour one. I'm lost on how to solve that too.

      If anyone here knows much about it, I'd love either direct advice about it or a recommendation for how/where to learn about this stuff. It's super appreciated!

    3. Want to get a 3D printer for miniatures that work well with open source software

      I've started to look into getting a 3D printer mainly for printing minis and terrain for TTRPGs. For the aficionado and print quality the best printer type seem to be resin based printers, but I don't think I'd be able to deal with the toxic fumes in a safe manner. As such I've settled on looking at filament based printers and I don't really need super high fidelity prints.

      I need one that works well with Linux and preferably OSS. I am willing to pay for closed source software (or OSS) if it runs on well on Linux. So if you know of any software that is easy to get started with I'd be happy to hear about it. If you know of any models or makes that I should avoid I'd also appreciate a heads up!

      Any other advice for someone just getting started with 3D printing?

    4. People who contribute to libre projects - how do you find time for this?

      First of all, I want to say very big THANK YOU for all who contribute to various libre, open source etc. projects. I'm so happy that people love sharing knowledge, skills and fruits of their work.

      But to the topic - how do you find time for it?
      Whenever I update my Debian or Axpos or any other libre software I see soooo many updates/changes made by (probably soooo many) people. And I always ask myself a question - when did they do that? Where have they found time for contributing? For me full time work makes me so tired that it's the last thing I think about after work hours. Especially in the office job, after x hours of sitting before my monitor I truly hate every next minute after work. I would love to contribute some code, I would realllly love to. Sometimes I find some bugs and try to report them and that's all I am able to do. What frustrates me the most is that I have abilities to code because it's my daily job, but I don't have energy to do that.

      So, could you tell me how do you find time and energy to contribute to libre projects?

    5. Detailed astronomical observation logging with a microphone and AI

      I'm into astronomy as a hobby, and it's useful to have a log of the things in the sky you've seen. Many people take handwritten notes, but my handwriting is awful and having to write notes takes away from enjoying the views through the telescope.

      So after being inspired by AI note taking applications I've read about online, I decided to give it a try while out observing.

      First, I take my recordings and run them through Whisper's speech to text engine. Because my recordings have frequent astronomical terms, it seems to be more useful to run the larger models (or the new turbo model), because they seem to do better identifying the names of moons and constellations.

      Next, I run Ollama and give it a prompt like:

      Here is a speech to text transcript of an observation session. Create a detailed log of the session, using only facts found in the text. Do not add your own interpretation to the text.

      I'm still experimenting with prompts and models, but oddly it seems like shorter prompts give better results. So far, the type of model doesn't seem to matter so much as the number of parameters. Gemma2 27B outperforms llama 3.1 7B, but llama 70B outperforms both of them (again, I think the larger models have more context about which astronomical terms are important). Here's what that gets me with basically no work on my part:

      **Observation Session Log**
      
      **Session Details**
      
      * Date: October 3rd, 2024
      * Location: Wolf Street
      * Telescope: Teleview 85 (also referred to as 80)
      * Observer: [Not specified]
      
      **Targets Observed**
      
      1. M29 (Open Cluster in Cygnus)
      	* Time: 2057 - 2101
      	* Eyepiece used: 18.2mm
      	* Notes:
      		+ Found using star hopping from Sater
      		+ Appears as a faint open cluster with 6-7 distinct stars
      		+ Stars are fairly even in brightness and color
      2. M39 (Open Cluster)
      	* Time: 2109 - 2116
      	* Eyepiece used: Ultra-wide angle, 18.2mm, and 8.5mm (noted as a mistake, actually
      using 7mm)
      	* Notes:
      		+ Found using star hopping from Deneb
      		+ Appears as a larger open cluster with more differentiation in star magnitudes
      		+ Stars appear bluer than surrounding stars
      3. Alberio (Double Star)
      	* Time: 2120, 2155
      	* Eyepiece used: Ultra-wide angle and 7mm
      	* Notes:
      		+ Found easily without a guide
      		+ Appears as a beautiful contrast between colors with constituent parts standing out from the surrounding stars
      4. M15 (Globular Cluster in Pegasus)
      	* Time: 2120 - 2130
      	* Eyepiece used: Ultra-wide angle, 18.2mm, 7mm, and Barlow (2x) with 7mm
      	* Notes:
      		+ Found using a bright naked-eye star as a guide
      		+ Appears as a slight smudge or fuzzy patch with averted vision
      		+ Not resolving individual stars at any power
      5. Saturn
      	* Time: 2140 - 2150
      	* Eyepiece used: Low power, highest power (with a star chart to confirm moon positions)
      	* Notes:
      		+ Three moons visible: Rhea, Enceladus, and Titan
      		+ Striping on the surface of Saturn visible at highest power
      
      **Session End**
      
      * Time: 2157
      

      I'm very happy with the quality of the notes. It's much, much better than my handwritten notes and much less work, so I'm likely to do this more consistently.

      Hey guys, anyone else into keyboards? Would love to hear about what you use or experiment with, I've only been into the hobby a few months so I am still pretty new. I'd love to hear your guys set up and what got you into it, how it's evolved.

      Currently rocking a Keychron Q2 (65%) with Tecsee purple panda switches and Drop MT3 Cyber keycaps - Co piloting this is a KBDcrafts Addams numpad with their s2 engine switches.

      I do also have a keychron Q8 (Alice) in transit - I plan to swap the switches to the KBD s2 engine switches as I am really liking them on the numpad. I ordered this model because my carpal tunnel issues are what awoke me to the mechanical keyboard world, the alice layout isn't perfect but better than standard for ergos it looks like.

      Early on in the hobby I was convinced I'd be a tactile switch guy, but the s2 engine switches really changed my mind on liking linear, eager to try a full board with them.

      This got rambly, but would love to hear from others into the hobby!

      Reject modernity, return to analog

      Let's talk retro tech, or anything of the sort! What projects or hobbies are you currently working on? Are you leaning towards a crisp hi-fi sound for your turn-table (yo), or just browsing eBay for old broken tech you know you don't need? Is this submission just a cry for help, because I've found myself browsing old Bose Wave systems from days gone by?

      I have a box full of old Gameboy motherboards I need to do something with (the current plan is to gift my close friends their own modded Gameboy, because seriously why can't I hold all these Gameboy motherboards). Then there's my AIWA Walkman that needs a new belt, but I've never cracked one of those open before, so we'll see. Then there's this Gameboy Camera mod that is keeping me up at night.

      What about you fine folks? I thought about posting this to ~tech, but I thought ~hobbies was just as relevant, since this isn't exactly leading edge stuff (though it may be in the retro tech space!)

      I've got a K40 laser engraver that I've had a lot of fun getting up and running with K40 whisperer on a Raspberry pi, and lately I've been thinking about getting a cheap 3d printer. Does anyone have an entry level 3d printer they like and want to recommend? What kinds of projects do you like to make? Anybody have a desktop cnc or other fun toys? Let's hear about 'em.

    10. Dvorak, Colemak and other alternative keyboard layouts

      I wouldn't really consider it a hobby, but couldn't think of where else to try and have this discussion.

      How many of you have ever heard of, or even considered the idea of alternative keyboard layouts!? As unanimous as it is, why are the letters of the alphabet even placed that way on our keyboards anyway? Alternative keyboard layouts attempt to optimize the layout by placing letters in such a way as to make typing more ergonomic. Often ideas include focusing on the home row, rolling fingers, alternating hands, high frequency letters on index and middle etc.

      Some examples to look into if you've never heard of the concept:

      • Dvorak, the most well known alternative keyboard layout. Prioritizes alternating hands by separating vowels and consonants by hand.

      • Colemak. As opposed to Dvorak, prioritizes rolling the fingers rather than alternating hands and attempts to limit same-finger bigrams.

      • BÉPO, a layout optimized for the French language!

      • Others include Carpalx, Workman, MTGAP, Norman and many, many more. Creating rather than using layouts has sort of become a hobby for some...

      So what do you think? Supposed ergonomics vs standardization. Would you ever consider switching or do you think it's a bunch of hocus pocus? Perhaps you have switched or tried to switch and would like to share your experience.

    11. Dying PBT Keycaps

      I just got my /dev/tty blanks in from Massdrop and I an thinking of dying them to match my current ABS colorway.

      I have looked at the guide and I think I am able to do all that, but I am wondering what kind of look I am going to/can get by dying the gray and red caps?

      I assume the gray caps would just yield a slightly darker color, but I am curious if I can get an interesting shade of brown by dying the red keycaps with some other color (or just more brown?)

      Any hints on dying the colored caps or dying PBT in general are appreciated.

      I'm only a beginner down the rabbithole known as mech-keebs, but I thought I'd source some thoughts here. Apologies if this has been expanded on in other ~hobbies threads.

      Those of you who have been in the mech game longer, what switches have you tried? What do you find are your personal preferences on switches and why do you think that is? Have you ventured away from the very popular Cherry MX switches?

      What about keycaps? What are your favourite profiles or colourway designs? Preferred material? I am currently rocking a DSA set of keycaps from one of my favourite designers, MiTo: https://mitormk.com/legacy-dsa/ I got the blue/black Tron-inspired set. I gotta admit, I was a little skeptical of ABS caps, but they're really nicely textured in a way that's reminiscent of PBT, but without that powdery grippiness.

      Tell me about some of your favourite layouts too! I hear some pretty aggressive proponents of tenkeyless layouts, but I just really like my numpad for lots of numeric input. If it were just a gaming keyboard, I probably would be pretty happy with TKL though.

      Are you working on any new projects right now?

      Looking forward to all the responses!
