The video is from 20 Jul 2019 and the moon landing from 1969! This is some unfinished code for a lunar lander style game. At the time I was doing some x-y graphics using microcontrolller DACs for learn.adafruit.com/dac-oscilloscope-images

Some of the code is rather complex as I got a bit focussed on producing cool looking stuff but the sound meter isn't too bad. I added an explanation to the Instructables article mentioned in the description and below. I spotted two bugs while reviewing the code, the children can have some fun fixing those :) www.instructables.com/MakeCode-Fun-on-the-4tronix-CubeBit-an-RGB-LED-Cub/

I'd be interested to know how it goes and if you have a 5x5x5 one how it looks and performs. The 4x4x4 is owned by a 4 year old now. Her favourite is the second falling mode on the rainbow code - it's surprisingly mellow.

@@kevinwalters2076 will do, we have two 3x3x3 cubes. I’m just reading through your code explainer. Any tips for tweaking the code for a 3 side cube? Thanks!

@@gridrunnersshack6337 Changing the height and size to 3 would do it. Then there's the option of fixing the two bugs mentioned in article. I just did all this and made a v1.1 available in makecode.microbit.org/_57JaqccJg7eF I no longer have a Cube:Bit to test on. I tried it out on a Kitronik Zip Halo HD (uses P8 rather than P0 to talk to pixels) and it looks like it works...

You might also be interested in github.com/kevinjwalters/makecode-examples/blob/master/microbit/cubebit/cubebit-priseccol-1.hex - that shows primary and secondary colours on the Cube:Bit and the buttons on micro:bit let you turn down the brightness to a low level where it's pleasant to have a close look at the pixels. If you have a magnifying glass you can see the individual red, green, blue LEDs, the bonding wires and controller chip.

I plan to write an Instructables article on this but in the meantime keep an eye on github.com/kevinjwalters/makecode-examples/tree/master/microbit/cubebit

Here's the Instructables articles: www.instructables.com/MakeCode-Fun-on-the-4tronix-CubeBit-an-RGB-LED-Cub/ That includes published links to the code and some notes on whether each program works on the V1.

@@kevinwalters2076 Both I & my Cube:Bit thank you!

I think it's this one github.com/kevinjwalters/circuitpython-examples/blob/master/cpx/cpx-basic-standalone-synth.py and there's a link to Adafruit article in the description showing how to use the CPX as a MIDI controller and sound module. Code might need a few tweaks as it was written for CircuitPython 4...

That was the happy accident on about the tenth take with nine previous disasters!

I waited about a week for rain and then it was vertical and during the daytime so didn't work for this video! I used a video in the end for the background. CircuitPython does have an audiomixer which means it could do the two together (background + fx) but it may not have been implemented when I shot that video plus there are still a few audio related bugs being ironed out. The different notes are implemented in ruclips.net/video/1BxlNVgzosY/видео.html with the audiomixer for polyphony.

Yes, the infrared send/receive is one feature the Circuit Playground Express has over the generally more advanced Circuit Playground Bluefruit. I wrote the code out of practicality as I needed a way to fire the shutter on the camera without nudging it for a stop motion animation of a jigsaw puzzle. I think there is an expensive Sony remote and there are cheap third party ones but that seemed like a waste in so many ways given I already had hardware capable of it. The IR from the CPX is surprisingly effective/powerful, there's no need to point it at the camera. I made a minor enhancement to Adafruit's library to support the Sony IR codes as they are not always an integer number of bytes.

@@kevinwalters2076 Nice. Yeah, having multi-purpose programmable devices like this is... all sorts of useful. :) (Granted, I still like dedicated hardware for some things, too... but... there's a sweetspot somewhere, or just trade-offs, or something.)

There's definitely a problem with the dma transfer of data to the pwm code but I'm not sure where it is and this demonstration only covers one particular trigger. I suspect there are multiple underlying issues as I have other code which can crash CircuitPython. I added tickets to the description if you're interested.

For this case it's possible but there's a few other things that can trigger crackles and I have other code which happens to do PWM on many GPIO which will crash CircuitPython if PWM audio is playing. I added tickets to the description if you're interested.

@@kevinwalters2076 I tried playing an audio file and use PWM to drive an LED, first time it works most times, second time it always crashes. I took out the PWM LED control and the second time around it crackles like an old LP... It is very repeatable, still no word on a fix? Upgrading to 6.2.0 makes it sound worse.

Thanks, I've got a few more bits to add, I'll put it on GitHub next week.

@@kevinwalters2076 👍

I put links to the GitHub repositories in the description. Most of it works well now. I need to do a bit more documentation but the MicroPython library docs cover most of it. I also need to work out the best way to add in the compass calibration as there's likely to be an offset which messes up compass.heading().

I put some more detail in an article on Instructables: www.instructables.com/id/Using-the-Kitronik-Inventors-Kit-With-the-Adafruit/ Another video with some more demo code: ruclips.net/video/3qBej1OPKVY/видео.html

@@kevinwalters2076 Hello Kevin, Could you add the instructions on how to copy the libraries to the CLUE drive onto the Github page ?

Adafruit Guide with code and many other things is now published: learn.adafruit.com/clue-sensor-plotter-circuitpython

Yes, they are part of the ATSAMD51 processor chip, described by manufacturer as "Dual 12-bit, 1 MSPS Output Digital-to-Analog Converter (DAC)". There are some unresolved peculiarities with this pair of DACs but these would only be noticeable for higher rate applications, one discussion is in forums.adafruit.com/viewtopic.php?f=24&t=153707

The controller code is capable of it but the Korg Volca Bass shown in the video is monophonic. There are three oscillators on the Volca Bass which can be sequenced individually but I'm not sure if they can be used individually over MIDI.

I only really put this video up to add a visual example of a MakeCode Arcade bug for a bug report to Microsoft. The bug isn't specific to the PyGamer, it would apply to all Arcade hardware devices. For games in MakeCode there's a *lot* going on at forum.makecode.com/ and some of the games/applications also make it to the front page arcade.makecode.com/

Thanks. This is some very unfinished work which was related to an Adafruit Guide I wrote called *Making oscilloscope images with DACs* (link is in the full description here). I'd implemented just thrust, gravity and primitive collisions to make that video for a certain anniversary. I'm looking at MakeCode Arcade at the moment but if I get some spare time I'll finish the game.
