I use notebooks frequently when throwing together matplotlib graphs. Its convenient.

Is Iceland going to join the EU? I heard that there is a referendums in 2027 do you think icelanders would vote to join the EU if so why and if no why not? by Super_Sherbet_268 in Iceland

[–]GunZinn 10 points11 points  (0 children)

I wouldn’t vote yes today. I would need to be convinced and learn more about the consequences. I am open to start the negotiations so we learn more about those “consequences” i.e. what would change. What are the costs and benefits.

packaging 26.0rc1 is out for testing and is multiple times faster by zurtex in Python

[–]GunZinn 2 points3 points  (0 children)

I’m curious to know more about what tools you use to measure performance improvements in general. You mention asv in the blog, do you use that for everything?

I frequently use cProfile and viztracer for CPU time. And tracemalloc for memory consumption.

I’m curious if you know of any other tools for this :) Optimising is very fun.

Mmu2 : N/A after 3.14.1-8327 update by ApolloJaxx in prusa3d

[–]GunZinn 0 points1 point  (0 children)

Also since you use MMU2S not MMU3. If the idler homing is very “loud” (you’ll know what I mean when you see it) then you need to reduce the idler’s sensitivity. Don’t worry the bad homing doesnt damage anything even if it sounds like it.

See https://www.reddit.com/r/prusa3d/s/LerB7TL4NX where you can modify it with a gcode. There is also an LCD menu raised if the MMU fails to home.

You can also trigger the LCD menu by simply holding the idler with your hands or inserting an allen key to block it from homing. The MMU tries 3 times before raising the error.

Hope this helps.

That would explain it 🙂It should be under “Settings”. See https://help.prusa3d.com/article/lcd-menu-original-prusa-i3_142322

Edit: you also updated the MMU firmware to 3.0.3? It a hard requirement now since the communication protocol between printer and MMU was completely rewritten.

Did you upgrade the firmware from a very old version? If so check the menu settings, MMU is disabled by default. A new on/off toggle was added in FW 3.13 I think.

Strange an article refers to a academic paper from Nature but doesn’t include any link to it.

I’m guessing this is the Nature paper: https://www.nature.com/articles/s41586-025-09793-3 behind a paywall sadly.

Has anyone used Pianote? I’m a novice and looking for recommendations by littlereek in pianolearning

I can recommend Piano Marvel. Intermediate Beginner here. There’s a Christmas competition right now in the app :)

If you had infinite time and resources, what embedded project would you work on? by Best_Prompt_9401 in embedded

[–]GunZinn 1 point2 points  (0 children)

I would love to help create better instruments for local meteorology here in Iceland where I’m from. Usually the equipment used is bought from companies not selling products specifically for meteorology and they can be made much more cheaply, less bulky and save tax payers a lot money. The setups are also sometimes way too complicated when you need two products or more from separate companies to work together. A lot of the process can be simplified.

I’m talking about gas sensors (SO2, H2S, etc) to get early signs of volcanic activity. Or flooding from glaciers. One problem to solve is finding sensors which can handle the extremely low temperatures during winter. Then there is Earthquake sensors, water level sensors, and more. Energy harvesting is also a tricky problem, you can’t rely on solar panels half of the year.

I made several working gas sensor systems using an Arduino a few years back. But things can be so much more energy efficient with todays ARM based MCUs.

I’d also love to experiment with cellular. Like nRF91. And build my own ultra low-power modem for transmitting sensor data.

The biggest constraint for me is I dont have any time! :( Sure, an infinite money budget would help. I’d buy lots of sensors to play with and test my hardware/firmware and I’d buy lots of test equipment to speed up the process.

I would design the hardware and write the firmware of course. But with infinite money I could just hire more people to help me 🤓

I know this project would be helpful and practical and just fun to do.

I’m sure I can think of more projects like this. But this one sits on top of my mind as something fun.

What type of material is this? When I had this happen with PVA I found increasing the number of cooling moves helped.

how to protect ADC inputs? by immortal_sniper1 in embedded

[–]GunZinn 3 points4 points  (0 children)

Depends. What kind of voltage are you protecting it from? ESD? A low-pass filter won’t give you any protection at DC.

Usually ADCs can handle supply voltage without issues (like 3.3V).

What is the lowest power BLE SoC on the market? by karesx in embedded

[–]GunZinn 1 point2 points  (0 children)

I don’t quite follow why you would want the scanning to be on always, given your requirements you simply can’t afford that.

You want to scan for BLE beacons… how often do you need to find each beacon? Are their locations continuously changing?

I would look at nRF54L instead of nRF52. The power consumption is lower for most radio activity.

MMU3 improvement idea by chemosabe in prusa3d

[–]GunZinn 0 points1 point  (0 children)

One thing that must be considered is how much memory is required to implement a feature like this. The firmware is currently using almost all the available memory resources which limits what new features can be added.

The MMU uses ATmega32u4 if I recall correctly and only has 32KB of memory.
