A speech therapist wanted to implement the idea. The need to have the microbit 'hot pluggable' arose. This means that the system needs to cope with the microbit not being plugged in when it starts up as well as when the microbit to be plugged in. The...
I found a nice silicone cover for the microbit (a Kittenbot). Then I tried to stick it onto the smooth back of a communication device...I found some sticky back Velcro with extra sticky glue that seems to do the trick. The silicone is a hard thing to...
A block diagram of the system setup is shown below. The base.exe program runs on the communication device and monitors the USB port that the receiver microbit is connected to. When a trigger is received from the receiver microbit, a software keystroke...
I am sending a hand shake kit to Aragna Ker at UCPLA for trial. This is a great opportunity to get some real-world feedback. This gave me the kick to test out a couple of off-the-shelf wrist holder solutions for the microbit. Much as I like my own home-made...
A block diagram of the system setup is shown below. The activity_indicator.exe program monitors the window running the speech synthesis software. When there is a change in the number of black pixels in the monitored area of this window, a trigger is...
This log answers the Design requirement for the Hackaday 2020 prize entry rules:Design-Is there a depth of design detail available (like a system design, CAD models, project test methods, etc.)? Is there base-level planning for the functionality (e.g.,functional...
Raspberry Pi and Micro:bit interface board returned from OSHPark and a simple uPython script written for the BBC Micro:bit using the two A/B buttons for faster/slower.Will also run from any of the Raspberry Pi SBCs. Code samples in C, and PythonCode...
This log answers the Production requirement for the Hackaday 2020 prize entry rules: Production-Is the project realistically reproducible (taking into consideration necessarymaterials, skills, and production processes)? Are the manufacturing processes...
Ouch, I really didn't think it was so long since my last project log entry. I have been Just IoTing, Just not sharing with people what is happening. So to say sorry, and catch up:First, the world has changed a bit. The BBC Micro:Bit is now available...
One of the main learnings from the first version of AlgaLite was that students and makers had a limited time at a workshop to get acquainted with all the different tech stacks related to building the project. While the mechanical and electronic assembly...
I set up a hackaday project page in '16 for the competition that year, but didn't make enough progress to get anywhere. But I'm back! This year I started to use the BBC Micro:bit. The microbit is a single board aimed at 11-12 year old school students....
Once I had the mechanics done, I started to work on the programming. Setting the speed of the servos was easy enough:import microbit microbit.pin0.set_analog_period(20) microbit.pin0.write_analog(int(25 + 100 * degrees / 180))But then making it turn...
Taking a nice long summer vacation and I have had the opportunity to visit Micro Center in Philadelphia a couple days ago and I was able to pick up a couple of great things including a new budget laptop I am typing this post up now. If you live...
I started with the practical work for the project. I assembled the electronics that I have available and tried to organize them. Since I am going to be putting the motors underwater using a tether, I will need to account for...
The LED matrices I'm using in all the other PewPew are great for several reasons: they have large pixels and small resolution, perfect for the kind of games I want to teach, where you don't have to worry about graphics. They are made of plastic, so are...
