We built on the @openflexure.bsky.social platform to combine a 3D printed microscope chassis with both a 3D printed condenser and objective lens.

Now we have the entire microscope, including the optics, printed for less than £7.00… and it works!

On @fm4.orf.at's #sunnysideup today we have a new but vintage sounding blues track from Peter Cruseder, the Wallners are looking inward, we've travelling through France and Colombia, playing vintage Afro-disco made in Rimini and, basically, it is great to be back: 10am

still processing this loss… never met John personally but his voice and wisdom accompanied me for almost two decades on @fm4.bsky.social
I’m badly hoping FM4 is going to replay some archived shows with John‘s great voice
Today on @fm4.bsky.social #sunnysideup we're going to honour our founding father (or beloved crazy uncle?) John Megill with his own music and the music he loved; and carry on the spirit he pioneered and embodied; 3 soulful, joyful, reflective, unconventional hours: 10am: fm4.orf.at/player/live
