    I never saw myself getting a tattoo. But this Undertale quote has been with me for 10 years now, through every playthrough, meaning more each time. At some point, it stopped being just a quote... so I made it part of me. (i.redd.it) [Original creation]

Ooooo, it seems that mass of fermenting dregs are going there! Its an amazing concert

I went there last year. I saw the schedule online and picked a concert. Note that in most websites you need a Japanese phone number to book tickets. I emailed the promoter directly and asked for a reservation and they happily helped me with that. The concert I went to also sold tickets at the door, so that's an option too but it's not guaranteed that you'll get one

All the annoying tasks I had to do that would take me days, I now get done in half an hour. I use Claude with the mcp server and kicad happy.

One practical example is cap derating. I usually leave it empty with xxxV. I tell Claude to run through the schematic, find the power rails and fill in the voltage rating according to a x derating spec. Of course I need to check everything but its still faster than doing it all by hand.

Same thing for basic components part numbers like resistors and capacitors. I just specify the preferred manufacturers, special details like dielectric and let it run

Bortle 5, but using a light pollution filter

afonsus

Details: - Date: 19/Aug/2026 - Exposures: 31x180s Lights, 5x180s Darks, 10x5s Flats, 10x5s Darkflats - Gain: 126 - Sensor Temperature: 5ºC - Guiding: Yes Equipment: - Camera: ZWO ASI294MC Pro - Filters: SVBONY SV260 Light pollution filter - Telescope: Orion Newtonian 8"/790 mm N 203/790 (0.95x reducer/flattener) - Mount: EQ6 modified with Onstep

Processing: - Graxpert (gradient removal) - Siril (generalized hyperbolic stretch, spectrophotometric colour calibration, background neutralisation) - Syqon prism and parallax (denoise and sharpen) - Syqon starless (star removal) - Photoshop (levels, curves, saturation, camera raw filter, star mask combination)

Thanks!!

I have an issue where sometimes, after creating a new footprint library, the other ones disappear from the browser. But closing and opening the footprint editor fixes it

Clear skies for all of you! o7

Thanks for the reply!

Haha yes! Putting stuff back together is harder for almost everything!

I think I'm going to give it a go. I was trying to see if the front element was just one lens or more. But I can't seem to find a diagram online.

afonsus

I just wanted to add that I never disassembled any of the telescope optical elements. I only very rarely remove the lens hood.

afonsus

Awesome!! I also made one some years ago!
