[emoticon:d6dd260102fd406884fc96b8bc59760b] I received the same! Gotta love it when a company commits to their April Fools joke to this level! Guess I better start figuring out how to fold a tinfoil hat! [emoticon:6d505171faa4497c85c5ca27290c555d]

I think I've found another use for the Aluminium foil. As the granddog and I were walking today, I heard a loud hammering and looked up to see a large woodpecker pecking at the side of a chimney. Unfortunately, by the time I got my phone out he had stopped hammering so I've suppressed the ambient noise in the video. I had to capture a frame out of the video to identify it as a Northern Flicker. The hammering behavior is the bird's way of announcing its territory. Causes quite a lot of damage. I think the foil would deter it, but I don't think I have enough in my roadtest kit...

Congrats on the road test package and testing.

Ive received my road test package too, and have started tests on my test victims......I mean voluntees.

Good luck

Good luck on your project and it’s testing!

RE: Arduino Uno Q - USB Audio

Nice work!

Have you (or [mention:d214a0a0f5594ee19515b2a3782e7070:e9ed411860ed4f2ba0265705b8793d05] or anyone else with kids/grandchildren etc) heard of "Tonies"? I learned about it about a month ago, it's something all mums desire for their kids (but in reality are unaffordable for parents). It is basically a cube-shaped audio player, with a NFC surface on top. Then, parents are supposed to purchase plastic toy characters which have embedded NFC tags. The child places it on the cube, and the cube makes a request to the cloud, to download the appropriate audio file (either music or an audiobook) into Flash storage. There is enough capacity to cache lots of files, so that subsequently there's no delay to download the files.

The ridiculous thing is that each plastic character costs about £15, so effectively it becomes more of a gift for aunts/uncles to give, rather than parents to buy, because a child would soon want different music/stories. It's as crazy as if iTunes were to charge £15 for a song!

Tonies is very popular, because it visually looks very "instagram-friendly", with all the cute plastic characters on magnetic shelves, so you can stick them on a wall near the child's bed etc. And when parents get together, if other mums see it on a shelf, then all of them want it for their kids. Plus, many department stores have walls full of the different characters in see-through pouches, to encourage people to build a collection for their toddlers. Really clever marketing all round.

I wish there were an open source alternative, perhaps using an off-the-shelf better quality bookcase speaker. For music, Tonies is actually very poor quality in my opinion (since it has a small speaker in a small plastic case), it hurts my ears listening to a children's song on it.

Nice post, good sound.

Very cool! Thanks for sharing.

I am currently working on a simple animation panel (64x32 pixels) that will include a MP3 player for my Grandkids. The idea is to allow them to generate some images that can be animated onto a fixed background image (think simple flip books with some editor tools to provide side scrolling). Tie in some triggerable sound clips to provide entertain sound bites.

insightful post thanks ! I was a bit disappointed that object classes did not include "shark", "yellow rubber duck", "deer", "squirrel" , and "sasquatch" :-)

I was also surprised at the webcam frame rate, its alot faster than I would've guessed. I'm always thinking for object detection a webcam isnt fast enough, Arducam publishes a 120 fpm. The raspberry pi AI camera tho is comparatively slower than both when used at full resolution.

RE: Arduino Uno Q - Standalone Operation

so default it boots up into ubuntu without loading anything ? then some setup to enable features and IP address ? Its interesting, so 2 operations running the same AppLab login ?

RE: Arduino nano r4 review

Hi,

you said: "USB problem"...

Last week I purchased a Nano R4 at Farnell.

For the first check: I just unboxed my new Nano R4, connected on the USB, started the Arduino IDE, checked the right board, selected the connected USB-Port, then I read the board information.

Hi,

you mentioned: "...USB problem"...

My first impression.

Last week I bought a Nano R4 from Farnell.

For my initial check: I unpacked my new Nano R4, connected it via USB, started the Arduino IDE, selected the correct board, chose the connected USB port, and then read the board information.

The board works perfectly, and I was able to get it up and running in just a few minutes.

Of course, I made sure to install the latest drivers in the Arduino IDE.

This applies particularly to the CMSIS and JLink drivers; I installed the original drivers for each.

Yes, and Microsoft forced us to buy a new PC last October because of Windows 11. Anyway, I'm using Win11 Pro and connecting the board to the PC's USB 3.0 port.

The board already has an RTOS installed, so it's essentially plug-and-play, making it easy to get the board up and running. -> Arduino IDE, last Version.

I'm not a fan of unnecessary experimentation when it comes to setting something up for the first time.

Only after that can I experiment, including with software drivers on the board.
That way, if something is configured incorrectly, you can revert to a working setup. That also means backups, backups...
The Nano R4 is new to me, so I'm really looking forward to learning a lot.

I'm very curious to hear about your great experiences with the Nano R4!

Best Regard

Gerald

Nice. You make it look easy.

Thanks for sharing your roadtest experience. Looks like out of the box, Arduino comes preloaded with examples and some cool LED matrix animation.

Small suggestion may be light up the LED between 24 and C with to denote the temperature degrees symbol. The LED matrix looks handy, now we don't to look for an external display.

I thought of exploring the Arduino App Lab before I get my hands on with Arduino UNO Q but looks like they stopped us here unlike the Arduino IDE where we can explore sketches and other stuff without a board in hand.
