[Edit] The thing that I find the most fascinating is that all the complex design you see, are done with only using a pair of compass and rulers.

>FPV drone flying What sort of set-up would be a good one for a beginner?
That's the fun part: most of the stuff currently on the market is quite good. The quads, the gear — if a few people recommend it on Reddit, it's likely totally fine for a beginner and it will fly well. A few pointers: The guy we all watch on YouTube is called Joshua Bardwell. Regarding radio, the protocol you're looking for is ELRS. Everything has converged on ELRS, it's open source and crazy good. ELRS at 250mW will…
There's a surprisingly high number of people in my extended social circle who picked up archery as a sport. It's actually a complex discipline with a huge range of bows and projectiles to choose from, each having unique characteristics you have to train for. Training using VR equipment is picking up steam, as typically you need a sizeable amount of real estate to practice when the weather is bad.
> Training using VR equipment is picking up steam, as typically you need a sizeable amount of real estate to practice when the weather is bad. I always wondered, how does that work? Over in bullseye rifle we live and breathe dryfire (no ammo), but I understand the equivalent (no arrow) with a bow is a recipe for breaking the bow. Like my brain just cannot comprehend how to get enough reps to get good enough at a thin…
Prepping for tournaments is a field in and of itself as you need to time your trainings right to achieve peak form at the event itself.
My sister, who's been doing this competitively for a decade now, showed me an excel sheet her team has - there's an optimisation problem you have to solve to get every member to their best shape within the specified timeframe.
Also there are so-called "trads" - people doing traditional archery with period-correct technology, where the stakes are understandably lower.
Also they ingest, ahem, aiming fluid each meeting, so it's way more casual than what modern competitive archers practice.

Probably better to start with solid fuel motors? lots to learn before progressing onto liquid fuel motors.
Solid rocket motors are conceptually simpler, but much more dangerous and in many jurisdictions legally dubious to make yourself compared to hobbyist bi-liquid or hybrid designs.
Making solid fuel motors yourself is dangerous (and illegal without a licence in the UK).

That's impressive work! But how come the books are in mixed languages? Are they your books? Do you fix books for random people?
Hahaha, good observation :) I ran out of my childhood books (in Spanish) to fix, then I ran out of my GFs childhood books (in Latvian), so at that point I offered my services to anyone in the Google Zürich office. I got books in all kinds of languages I couldn't read, and a few chocolates and bottles of wine for my troubles :) Some of the most interesting books were especially challenging. One in old German that was…
Hydrophonic farming at home. You can play with sensors (acidity, humidity etc), LED lighting (frequencies, intensity, etc), vision processing (maybe throw in some AI buzzword here) to keep track of your plants and do some decision making. Bonus: You get to eat the stuff you grow :)
Can you share some useful sensors? Any good pH sensor that can work for some period of time without manual maintenance (cleaning the probes etc)?

Archery does seem like it's having a moment right now. I wonder if it's some combination of people wanting a more tactile hobby plus some vague apocalyptic undercurrents in society today.
Case in point: you can open-carry a sword, unless you're displaying violent intent. Concealed carry of any obviously dangerous blade is prohibited, which spurred speculation on what to do with, e.g. a bread knife.
Consensus in the community is that you need to hold a loaf of bread in the other hand.
I've been working on trying to help fill out the MeshCore network in our area for off-grid communications. Some of us are setting up solar powered, battery backed MeshCore nodes, they have no connection to power or Internet. You can use a small device (like a credit card or a small walkie-talkie) with a phone, or a blackberry-like device, to send/receive encrypted messages, chat on channels, or communicate on BBS-lik…
Is this similar to meshtastic? I've heard about it for a while.
My niche hobby is exploring patterns in Islamic Geometry and trying to re create them. It is an art of creating pleasing and aesthetic geometric patterns (from intersecting circles mostly). The art form is very popular in decorating Mosques and other Islamic monuments as human/animal representation is forbidden. [Edit] The thing that I find the most fascinating is that all the complex design you see, are done with on…

Have you ever come across Penrose tilings? If not, they might be something you’d also find interesting:
