Mirror, mirror on the wall, what will concentrate solar energy best of all? In the 1960s @NASAglenn was working to develop systems that provide electrical power in space. One project was a Brayton cycle engine that used a large mirror to collect the sun's rays. Info in ALT text. #NASAhistory

This concept continued development up to the late 90s, Space Station Freedom and Mir-2 (and early ISS concepts) were all intended to have solar-dynamic power production in addition to photovoltaics. Rocketdyne even built a test system. But ultimately PV got a lot better, meanwhile ISS became less ambitious, and solar-dynamic turned out harder than expected, so it was dropped early in ISS dev (Russia's Science Power Platform for ISS was the last major proposal using it)

Is there a reason the Mastodon Android app has had active development but no release for months? Several fixes plus big new headlining features in Mastodon 4 just aren’t here. Someone opened an issue and it was closed saying it wasn’t the place to ask.

@Gargron Plz consider writing on the joinmastodon website AND on the android/ios descriptions of the apps to ask people to use the mobile/web site instead of the apps for the time being. We are losing a LOT of new users because the app doesn't work well. Lots of complains about it. Plz tell ppl to use the web for now. It needs to be written on all the pages/sites where the app is available, so people know what to do from the get go, before they get a bad first impression.

Pride Toronto, misdirection of funds, settler-colonialism

It has come to light that #PrideToronto has, at time of publishing, willfully misdirected at least CA$2,850,000 of federal grant money that was meant for #Indigenous #artists. What's more, the various federal agencies who failed to prevent this have been unwilling to hold #PrideTO accountable.

Shout out to Tom Hooper for investigating this and making the results and sources public at pridegrants.ca.

Made a simple #breakout #PCB for the #UVC #led I found on Amazon, with ample room to add #filtering #circuitry and #current limiters later. The part is way too small to hand solder without experience so a cheap #PCBWay breakout is in order. Arriving Monday. Gotta love a quiet evening #tinkering 😀
3d printed black jig on a white surface that holds a glass rod, bookended by white luer lock fittings. A small blue pcb sits in a depression in the jig with a small UVC light sensor facing directly into the glass tube. A small gold UVC LED is placed nearby.
A line drawing of the UVC LED I found on amazon. Dimensions of footprint pads and casing are drawn. Below is a simple schematic showing the two LEDs (UVC and UVA) and their orientation with respect to the footprint pads.
A 3D render or the PCB breakout I designed. The footprint mentioned in the linedrawing is rendered near the top third of the PCB. At the bottom is a strip of pin headers in gold.
Back of 3d rendered pcb floating in a blue-gray void. White letters denote the pins. UVC/A + and - pins.

🌱 My Neighbor Mastodon

Just want to say thanks for the 15K followers. It's amazing how calming it can be for me as an artist to know that my biggest audience is on the Fediverse right now. Thank you from the bottom of my heart to everyone who contributed to this.

#MastoArt #krita

A digital painting illustration being a parody of an iconic scene of the movie "My Neighbor Totoro" but instead of Totoro it's a big Mastodon, and the two girls are replaced by Pepper and Carrot, the OC of my webcomic. The scene show Mastodon sleeping on the back in the forest, with on his stomach Carrot sleeping and along his arm Pepper sleeping. White butterflies dances in the air around the scene. The artwork is painterly, done quick.

While the algorithms of other social media platforms push users to see feeds that push them deeper in their own bubble, mastodon users are self-herding within servers that show local feeds (as one option). #MedTwitter existed across the entire platform. #MedMastodon is over 70% happening within med-mastodon.com

Community of interest or more segregated from other audiences?

I think it depends on the use cases for #MedMastodon. IMO communication among peers can be done by looking at the local timeline and ensuring peers outside the instance are being followed. Hashtags (on the other hand) are good for allowing folks across multiple instances to participate even if they follow noone. I think the size of the fediverse can make hashtags not good for ongoing discussions as thread of conversation become lost in folks "broadcasting".
