honestly it destroys lemmy experience for me because it makes lemmy look like a bot-cloned reddit. i barely ever see genuine posts at all.

Nice parts! I'm still waiting for my parts (slow post), which should arrive soon.

After some back and forth with their support I actually like them. When they can't do something, they explain it plainly and suggest that you modify the model. Time delays are just something I needed to adjust to after many years of using the PCB service.

I have decent experience using my own FDM printer and third party services using SLS, I design my own mechanical parts too. I know what you mean and I know joy and frustrations of owning a 3d printer. There's no arguing that quick turnaround helps design process tremendously. It's just currently I have to make do without one.

They (JLC) have requirements well specified and automatic rule checker rejects problematic parts. I had several virtual iterations with it before I got my parts dialed in. They should cause no problems.

As for them restarting failed prints, heh. I really hope not. Large machines tend to be loaded to the brim with multiple jobs combined and they are pretty reliable.

I don't have a 3d printer currently and will not be able to get one in near future.

Also not all 3d printing technologies are equal. Each has its strengths and limitations. FDM doesn't cover all bases.

Printing at JLC (self.3dprinting)
submitted 1 year ago* (last edited 1 year ago) by thwil to c/3dprinting@lemmy.world

Can we discuss printing using services (jlcpcb, pcbway, shapeways etc) here? Materials, limitations, personal experiences etc?

I'm having a strange experience with JLC 3d printing service. 72 hours is looking to be a week tomorrow. Customer support said that they "will try to ship it soon" after I contacted them after the order status hasn't been changing for 2 days

This is so different to their main business, PCB making, which is extremely sharp and smart.

Upd: after contacting them, they shipped the order.

Some counters, a DAC, a bunch of cd4052-like analog muxes and switches, opamps and even a 555. They use DIN symbols. Unless you want to replicate it exactly, most things can be guessed.

There's also a BBD chip for chorus.

Maestro was a synth made in USSR that was designed by Vladimir Kuzmin of Polivoks fame. Maestro takes after Polivoks but adds digitally controlled oscillators and 4-voice polyphony. I learned a few things from studying its circuits.

From the sound of it they take stuff that would biodegrade naturally and quickly, enriching soil, and instead convert it into plastic that may biodegrade, but very slowly and only when disposed of properly. How is this helping ecology?

So I tried the generator and it seems to be working. I also found out that you don't really need anything special for C++ to work with pico-sdk, it's already set up and they just don't advertise it much. Just add your .cpp files in CMakeLists.txt and it picks them up. Maybe there will be problems later on but so far it's just like that.

The generator is also a good reference of configuration options, like how to disable/enable exception handling etc.

No I didn't know about such tool. Thanks, I'm going to try it and post back later.

looking for c++ project template (self.raspberrypipico)
submitted 1 year ago by thwil to c/raspberrypipico@lemmy.ml

Is there a pico-sdk based hello world for c++? Basically CMakeLists.txt and main.cpp with a led blinker. On the surface everything is C based. Thanks!

The next chapter in DEC Rainbow 100 saga. Floppy formatting is not to be taken for granted in the Digital world.

dude.. have you been printing with steel cable instead of filament?

[-] thwil 1 points 1 year ago

i'm new to this so please excuse me if it's something obvious. the linked page says it doesn't matter which instance i'm registered with, just pick one. i followed this advice and i'm here now. i'm subscribed to a bunch of communities from other instances too. so what difference does it make that i'm at sdf and not somewhere else, where is the lesser drama to be found in all this?

Amazing. I also have a couple of these and if not for your post I probably wouldn't have noticed. It's a bit annoying, but it was cheap.
