Easy, Free and no markers Augmented Reality - location based AR For a few years, I have been a fan of Aframe and AR.js - these are fantastic tools for creating web-based Virtual and Augmented Reality.  CrowPi2 - Raspberry Pi laptop and much more.

A product that has kept  popping on to my radar has been the intriguing Turing Tumbles    @TuringTumble  I admit to being initially hesitant (is just a gimmicky marble run? - it isn't!) a marble powered computer. The idea is using mechanical ideas to visualise computing concepts is thought-provoking and I have always loved marble runs and 'Heath Robinson'/'Rube Goldberg' style machines; so  bit the bullet and brought one and I am impressed; it is great fun (more than just as a marble run).  Let's start with the packaging and components it is and feels like a high quality product. The components feel sturdy and well designed, the storage for the components also feels sturdy (see figure 1). The project book with the exercises etc is a mixture of puzzles and challenges, alongside a short graphic novel/comic; it all feels well executed and thought through. Online there is now a growing community  https://community.turingtumble.com/ where new puzzels are p...

Elecrow in 2020 released on kickstarter and now in pre-order their own site  (or Amazon.com ) an interesting take on the Raspberry Pi laptop - a laptop with a built-in sensor lab. e Image taken from: https://www.kickstarter.com/projects/elecrow/crowpi2-steam-education-platformand-raspberry-pi-laptop/description  It builds on their earlier Crow Pi system but looks much more like a laptop with a secret sensor kit. It includes a wireless mouse and a keyboard, with the cool idea that the keyboard fits over the sensor kit and can be used as and looks like a laptop. The version I received comes with a fantastic range of items, including the Raspberry Pi; power bank; books on python and scratch; RFID keyfob; remote control; game controllers; and many other components. A wide range of software and learning materials are installed on the SD-Card; including software to learn about AI. At the moment I have mainly been playing with it as a Pi based laptop but I am looking for...

In two recent posts, Makecode was used with the Enviro:bit from Pimoroni to try out a few ideas ( https://robotsandphysicalcomputing.blogspot.com/2021/06/pimoroni-envirobit.html  and   https://robotsandphysicalcomputing.blogspot.com/2021/06/pimoroni-envirobit-light-and-led.html ). In this post Pyton using the Mu editor was used to try out the Enviro:bit. As in the makeCode version, Pimoroni has provided both a python library (via Github) but also within the Readme.md useful installation instructions. There is at the time of writing a possible typo; to get the BME280 sensor (temperature, pressure, humidity sensor) to work; you need to add parenthesis in the line  bme = bme280.bme280() After that, it works fine and includes potential altitude measurement which I don't think is in the Makecode version (though I could be wrong); I need to play with it a bit more. To experiment the code below was used test reading temperature (in Centigrade), humidity (%), and altitude (f...

In a previous post, the Envirobit (  https://shop.pimoroni.com/products/enviro-bit  )  for the Microbit was played with getting temperature, humidity and pressure  ( https://robotsandphysicalcomputing.blogspot.com/2021/06/pimoroni-envirobit.html ).  In this short post a quick experiment using the sound and light sensor, to turn LEDs on the board to turn off and on beyond on light level. The code is set up when a clap happens nearby, light level is used to 'decide' whether the LEDs are turned on or off, below a threshols the LEDs go on above it the LEDs are turned off, Makeecode  Using Makecode makes this relatively easy to implement and fun.
