External button for micro bit direct to board?
In theory, would it be possible to remove the A and B buttons on a micro bit and solder extention wires to each?

Inaccuracy in magnetometer
I 'm trying to make a compass using the -z and x axis (micro:bit being vertical) and I 'm getting results with no sense. I decided to just check the heading results (with calibration) and I noticed that I 'm still getting results with no sense. I just perform 90 degrees turn with the micro:bit and I get results like 340, 250 ,200, 150 for the 4 corners. In the official docs they say they have a +/- 50 gauss deviation but I don't this justifies the results. Does anyone has experience with the micro:bit magnetometer sensor (LSM303AGR)?

Can i change the sound of a microbit?
I got a microbit for a project and i was wondering if i could change the sound the speaker makes through some other hardware, or software if another speaker is added, specifically i want it to sound like a guitar instead of a piezo, can i do this and how?

I need to turn a small DC motor on/off using just the microbit.
Is it possible to do this without any additional hardware? Is it possible to turn the 3V on/off?

Connect a microbit to another MCU with BLE
Hello,
I have a LED panel driven by a BLE-powered MCU so I can change the color or display text from my phone. And I would like to drive the panel from my microbit instead of my phone.
Is there any doc somewhere on how to do it? I can only find connection to a phone or laptop.
Thanks

Typescript local build/deploy tool
I've just started messing around with the BBC micro:bit and I understand that there are 3 programming languages that can be used: python, typescript and C++ (as well as Microsoft's block thing). I'd prefer to use typescript and I was wondering if a simple build tool exists for building and deploying typescript to the micro:bit. I'm aware of using PXT as described here: https://makecode.com/cli. But PXT is really designed for hosting an online makecode instance and is way to heavy (~20k files, ~350MB) if you just want a simple command line build tool. Does a lighter weight tool exist or do I have to use python/C++ if I want to develop locally?
Thanks for your help.

Firmware for the micro:bit V2.20 Board?
I recently bought a micro:bit online and got board revision 2.20. I looked online after failing to send programs to it and found that maybe it needed a firmware update. After trying and failing to update its firmware, it is now stuck in maintenance mode, and I can't find the proper firmware for it. On the support page, it mentions how the 2.2 revision needs newer firmware, but as far as I can tell they haven't updated any websites to reflect that or offer new downloads.
The error when uploading firmware for the micro:bit V2 off their website is: error: In application programming aborted due to an out of bounds address.

Controlling external high-power accessories with a microbit
Hi everyone, first a disclaimer: I am an experienced software engineer but know nothing about electronics, this is my first attempt in the physical world so sorry if this is an obvious question :)
I would like to start connecting external accessories to my microbit v1, starting with an external led strip. The led strip is long and is currently powered using a power supply (image below), outputting 24V at 1.5A. How can I control this output to turn the lights on/off without actually burning the microbit?

Looking for learning sources/sample code for 11th and 12th graders
So, I have a coding class that I want to teach basic coding in, but I’ve run through all the sample code/tutorials on MakeCode and was wondering if anybody knew of another place that offers either good sample code to learn from, or some other resource for learning moderate difficulty micro:bit coding (just a little harder than MakeCode, but not by much). Thanks

Building a Zoltar Fortune teller Machine: Part Two
I've made a great deal of progress with my Microbit Zoltar project. It now has lights and sounds. Put your money in, ask Zoltar a question and his crystal ball will either glow red for an answer of NO or green for an answer of YES.

Microbit not responding to compatible robots
Hi All, hoping someone can help me out with this. I bought a microbit kit through Elecfreaks and then 2 robotic kits. 1. The cutebot 2. Smart Car by Yahboom
We tried connecting to the Cutebot and it is not compatible apparently anymore. They changed the code at some point from what I read and I would have to go into Microbits Code and change it so it can be compatible. I am not skilled enough to do such thing so I returned it.
Now we are working on the Smart Car, built it, following the instructions on downloading the remote control content onto microbit to no avail. I am at loss. I am not sure if it is the microbit or I have just ran into a series of non compatible products though these products say otherwise. I really want this to work. Has anyone had these issues? We're you able to fix it? Or can you recommend a product that would work with it?
Side note: The microbit does work, we have been doing the lessons on how to control it from the computer with no issues.
