Google bribes iNaturalist to use generative AI — volunteers quit in outrage in c/citizenscience@mander.xyz
[–] AlchemicalAgent@mander.xyz 3 points 1 month ago

I don't thing anything is close to what iNaturalist used to be. I use it every year when teaching Biology and Environmental Science. Now I'm looking for something else as well.

I read through that entire thing, saw Charles, and just skipped right over it. That's perfect though.

All of my students get pictures like the second one because we don't look at the leaf itself. We use nail polish to make an impression and look at that. It comes out as a monochrome relief.

Very nice! The microscopes I use to teach biology are 40x objective (10x eyepiece). They're not the best, but true workhorses when it comes to durability.

The one with a bunch of golden lab dogs dressed in lab coats? It's still hanging on my fridge.

Looks great! What area are you in?

That makes sense. When I zoomed in and saw how they labeled auditory processing I was suspicious.

Advice on getting back into the hobby? in c/amateur_radio@lemmy.radio
[–] AlchemicalAgent@mander.xyz 2 points 3 months ago

I'm trying to get back into HAM after 30 years out of it. Starting with meshtastic let's me play around without spending a lot on hardware, and before I get my license back.

There are great prebuilt nodes for under $50, and as low as $20 if you build your own from parts.

Only based on what the listed specs are (11-12 mm). They don't ship until April 25th.

Agreed! Though their claim of making an impregnated wound dressing with good results gives me hope.

I ordered a 5,000 mAh to try out. It saves me from building something similar myself. Prototyping wireless charging is hard enough as it is without taking radio interference into account.

That's what I'm thinking too. Why have a PoGo port if you don't plan on waterproofing. I already have silicone plugs for USB-C ports.

Tower or Mast Recommendation? (mander.xyz)
 

I'm trying to get my home node high enough for LOS to other parts of town. The house unfortunately has a full hip roof, so I can't attach anything without going through the shingles. My current setup is a pole attached to an 8' garden fence. That gets me to about 15' AGL.

Based on the homes around me I need at least 30' of height to clear their roofs. I've given up on trying to get above the trees because they're old Oaks 50'-100' high.

I keep seeing collapsing fiberglass poles online but they're advertised as a temporary setup. Anyone have recommendations for at least a semi-permanent pole or small tower?

New Personal Distance Record! (47 miles) edit: 91 miles (mander.xyz)

My home node made contact with what I think was someone flying by with a RAK module. The GPS put it at a distance of 47 miles and height of 36,000 feet, along the path airlines would take from New Orleans to Houston.

I've had contacts with more distant nodes but this one was able to confirm receipt and I got a valid traceroute back.

Utah Senator Mike Lee Introduces Bills to Value and Audit Federal Spectrum Use (hoodline.com)

It sure will be nice for them to control all radio spectrum too, since all amateur and open use bands will be valued at 0$ and be immediately sold off to a corporate owner.

Recommendations for Vehicle Nodes? (mander.xyz)
 

I've been brainstorming ways to get a permanent node on my truck for various reasons. Here's what I have so far:

  • Hard-wired for power. The vehicle battery is pretty large, and I have a solar-maintainer installed with enough power left over to run a node.
  • GPS module for tracking
  • External antenna (915 MHz). I already have cargo racks on the truck bed so plenty of space to attach a mount.

Unfortunately I haven't found much in the way of hardware guides. Initially I figured a 33 cm ham antenna would be perfect but haven't seen much available. For the node itself I was looking at either a heltec tracker or a Wisblock with location module. Anyone suggestions?

New to Mander, a Lemmy instance focused on the natural sciences.

The Science of Cooking

We’re focused on cooking and the science behind how it changes our food. Some chemistry, a little biology, whatever it takes to explore a critical aspect of everyday life.

I'm not sure if this is the right community, maybe Introductions would be better. But I wanted to say my first week here has surpassed any and all expectations I had during signup.

If I hadn't taken the extra time to look at all available instances I may have missed out on having such a cool server as my base of operations for the Fediverse. Love the topics, love the user base, and looking forward to helping it grow.

A new analysis addresses five essential questions about biodiversity — the variety of life on Earth — that need to be answered if we are going to effectively conserve nature.
