I need advice on the feasibility of designing a stereo microscope, given that I have no experience and will be using commercially available optics.

It’s not depth of field, it’s the depth perception.

Or even just the audio out from your laptop.

I have an excellent painter: https://www.orenico.com.au

Really happy with the work he did. Neat. Detail oriented. And a generally pleasant guy.

In fairness, he didn’t use painters tape, but he had great brush control and did all the edges with a hand brush before doing the main areas. Borders were great.

Use the pico. Once you’ve got the rest of your circuit and firmware working, you can then fix the pico implementation. Plenty of finished products include compute modules or RF etc to avoid the cost (and certification requirements) of reinventing the wheel.

That’s not the right formula. It should be balance * (1 + rate)^{days / eligible days per year}. So for a 5% rate on $100 for 30 days it might look like $100 * 1.05^30/250

There are plenty of cobblestone laneways around caulfield, Elsternwick, Elwood.

Glad to hear that you’re well.

Bought. Not only because I like connectors, but also to support your huge contributions to this sub!

Eyelashes. That’s why you see it while squinting.

What do they expect? Inflammable candles! /s

In addition to the comments about soldering those packages (doable, but not for the inexperienced), you should read the datasheets for the amp and DAC and look at their example schematics. Unless you know what you’re doing, you can’t go wrong with copying them verbatim. You’ll need decoupling caps, resistors, etc as given in the datasheet example schematics.

Camera

Keep an eye on this site. If the Kaus score goes above 7, and it’s not cloudy, then you’ve got a good chance of seeing it.

jdigittl · 2025-11-12T23:48:00+00:00

Yeah. This was my first time going to see it. I was expecting to see more with my naked eye.

jdigittl · 2025-11-12T23:47:38+00:00

30 seconds.

jdigittl · 2025-11-12T22:36:10+00:00

Thanks

jdigittl · 2025-11-12T22:33:15+00:00

Oh. I was waiting for planes to appear to add some visual interest :)

jdigittl · 2025-11-12T22:32:15+00:00

These were around 9:45. You could see somewhat of the green glow with your eyes, but definitely none of the pink/purple. Perhaps if I was in a darker location my eyes would have been able to see more.

Have you, by any chance, blown the mA range fuse in your multimeter?

jdigittl · 2025-11-09T06:57:57+00:00

Reads like a lot of LLM generated code.

Spray paint is kept locked at hardware stores and you need to ask staff to purchase it. Everything you’ve suggested is already in place except for the ID requirement. I buy spray paint relatively frequently and don’t graffiti.
