Many many years ago, when I was a young stfn, I could speak some Welsh. And today I found a proof of it.

A short thread about Barbie, drills, and . This is our basic drill with an attachment to make standard size holes in plastic. Today we decided to put the second LoRaWAN gateway up – signals from some sensors didn't get through when the gataway and the antenna lied on the dogs' favorite couch in our tiny house.

@szescstopni that is beautiful engineering. Work with what you have

New blog post!

This one took weeks to write. It's about me finding a way to significantly reduce the power consumption of a Raspberry Pi Pico W working as a weather station, collecting environmental data.

I am also writing about powering the Pico using solar panels, and this time it's a success, my weather station can now run indefinitely, powered by the sun!

@yvan thank you! and good luck with your project, I'd love to hear about it :)

@steelman

There is also machine.lightsleep(), but from my testing, it did now make any difference from time.sleep(). And deepsleep is not yet implemented in MicroPython. Maybe it's different in C, but I don't know C (yet).

And yes, it can sleep longer if you want less granular data.

I read the article that you posted, I even linked it at the end of my post.

Nonetheless, thank you for the feedback, I really appreciate it!

@gim Yes, it does do overdischarge and overcharge protections, and it has a small radiator at the bottom to dissipate heat. As for 2), I don't know, I haven't reached that point yet

@stfn@fosstodon.org avatar

@steelman So you are saying that when the interval is too small, the sensor itself will heat and skew the results?

@stfn@fosstodon.org avatar

@quantensalat wow, I did not know such a thing existed, and it looks like a perfect, simple solution! Thanks for sharing!

@stfn@fosstodon.org avatar

@jo did you use C or microPython for your project? I'm curious how you changed the clock speeds. And the charging circuitry is kind of complicated, if I understand correctly you implemented your own solution instead of using an off the shelf controller?

Right now I'm also working on a different project, and I am also using Tupperware for the case, and had problems with placement of the sensors. I'll publish a blog post on it soon. Thanks for sharing!:D

@quantensalat "Also, we had to pull down the cutoff pin gently to ground for it to reliably wake up again."

What do you mean by this? Sorry, I'm not that will versed in designing circuits

stfn,
@stfn@fosstodon.org avatar

@quantensalat so it is to ensure that ground will always be 0V and not introduce some unwanted currents?

stfn,
@stfn@fosstodon.org avatar

@quantensalat right, now I get it!

@karlbunyan Thank you, you're the second person in the replies using that board, I need to take a closer look at it

stfn,
@stfn@fosstodon.org avatar

@dj3ei @yvan @steelman @gim @jo @quantensalat @karlbunyan thank you for the contribution, you are making very good points. One place that would for sure make the code more complicated is that I would need to attach timestamps at the Pico level. Right now I just send data from the Pico, and InfluxDB handles time-stamping of incoming messages as they arrive.

@markwalker there's the cell, cabling, and an overdischarge protection chip

The way sentences containing the German character ß get longer when uppercased was specially designed to create memory problems in C programs doing string handling

stfn,
@stfn@fosstodon.org avatar

@foone Probably not related that much, but I remember that in the early days of mobile phones, when every text message was expensive, there was an an outrage that Polish diacritics (ąęźćńż) were counted as more than one character within the 140 characters limit.

stfn,
@stfn@fosstodon.org avatar

@radovan @foone wow, I assume it's hard to read those people

stfn,
@stfn@fosstodon.org avatar

@radovan @foone right, so in Polish it's different, not using diacritics can make a large difference in meanings of words and sentences

stfn,
@stfn@fosstodon.org avatar

@sabik @radovan @foone In Polish it is also most often obvious from the context.

One fun example that just hit me is:

"Oddali mu cześć" - they praised him

"Oddali mu część" - They gave him back the part (part of something)

stfn,
@stfn@fosstodon.org avatar

@sabik @radovan @foone

"Widziałem ludzi na plażach" - I saw people on beaches

"Widziałem ludzi na płazach" - I saw people on amphibians.

Now I will be thinking all day about more examples, lol

@getur @radovan @foone I assume one of those words means a factory, what are the others?
