Never mind. I have the complete canon on DVD...

#

Now, if I could just remember where I put my DVD player...

But this time more puppets

lavish patrol
#

@lucid marsh Yep.

#

I gave up on DVDs back around...well, ~2008 interestingly enough.

I wanted to watch a Disney film, Wall-E. So I went out, bought a DVD retail, and sat down to watch it on a Macbook Air + SuperDrive. It scrambled the chapter order as part of a "copyright protection."

It didn't matter I owned a legit, name-brand laptop + their first party DVD drive. Didn't matter that I was using it well within my rights.

I did not own a TV or a traditional DVD player, and I was so disgruntled by that, it was the last DVD I bought out of principle.

Adafruit - can you guys take a look at these and maybe carry them? Emulation Technology here used to sell them - last I heard - Molex bought ET and basically killed selling these very handy devices, you may need to pick English at the top left of the page: http://www.mechano.co.jp/product.html

@rapid hornet - missed the last bit of the deep dive - so catching up now
looked up -ftree-vrp
Perform Value Range Propagation on trees. This is similar to the constant propagation pass, but instead of values, ranges of values are propagated. This allows the optimizers to remove unnecessary range checks like array bound checks and null pointer checks. This is enabled by default at -O2 and higher. Null pointer check elimination is only done if -fdelete-null-pointer-checks is enabled.

@proper trench has said she wants to do other versions on the MagTag. I hope she does a super low power solar version. Maybe remove the neopixels and replace them with two of these tiny solar panels. Hopefully that should be enough to keep the battery going if the magtag is mostly deepsleeping. https://www.digikey.com/en/products/detail/anysolar-ltd/KXOB25-12X1F/9990434

#

FYI The datasheet mentions that it works in low light and mentions how much power it gets in warehouse levels of light. so i'm hoping that it would be good enough for a magtag on a fridge (2-5 Watts/m2) . It wouldn't generate much power, but for for something deep sleeping most of the time, it wouldn't need to. (my magtag app has lasted two weeks so far)

Something I put in the chat but want to add here just in case: If TFT_RESET is also the reset of the microcontroller, and the BOOT state is latched on reset exit, it seems like you're setting yourself up for a race condition of MCU reset propagation time vs. propagation delay in these gates. You can probably tune your way out of it with a slow R/C pull-up/cap on the BOOT0 line itself (so that if this triggers, it takes a second to get out of it), and if you've already done that elsewhere, sorry for the noise!

Is there a Show and Tell tomorrow evening? Thinking about showing the Christmas present that I made for my wife.

I do believe that there is a S&T scheduled tomorrow, as well as "Ask an Engineer"

@fast forge Yup!

Do we have the ability to share our screen to show a short clip of the project working?

#

On the show and tell show yes. There will be a link in here before the show begins to log in to the stream sharing thing. It's set up such that they can do camera or screen share depending on what you are showing.

Interesting. The printer puts strokes through the Ohs, not the zeros.

It might be using the same printed symbol for both. Old typewriters did that with some symbols, like the number 1 and the letter L

@autumn turret You're right. I remember that now.

It was a good thing it was insulated, I would have been toast.

Oh that's cool @split gazelle I was using ImageMagik to convert to RGB data and reading it in raw. A library would have been a lot easier

@split gazelle what are the advantages or trade offs of doing that versus a bitmap file?

There might be @sacred isle, but it's one of those things where you can get SOOO caught up in that part, that the project stalls. You found a nice, simple, clever way around it. No messy "protocols", special data formats, etc.
