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

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!
