Earlier I posted about FreeCad and how Jo Hincliffe (@c0ncreted0g) had started a series of how-to guides on using the package. These guides have been thrown together and published by Hackspace Magazine! Grab yourself a copy for free here

PiWars and Small Robots at Calderdale College

Before the end of the summer term in 2020 an introductory microcontroller session was ran using tinkercad to simulate basic electronics with a micro:bit. As this sparked an interest in the students I decided to enter a college team into to 2021 PiWars competition. As we had two groups

micro:bit radio bluetooth bridge

We all know that the micro:bit is unable to use bluetooth or radio functionality at the same time. However...what would happen if we gave the sending micro:bit an extra external bluetooth interface?

Yes...I know it's been a while since the last post but I've recently started playing around with freecad Partly to start getting geared up for PiWars and partly to get the ender 2 gainfully employed and not sat there looking forlorn. It's certainly a bit of a giggle to

A summer of Robot building at the library

With the school summer holidays on the horizon, the idea of a robot building workshop was pitched to Kirklees Libraries who showed interest. A few potential ideas/designs were discussed and the one that seemed to fit all the correct holes was the PounderBot. The Pounderbot was a design created

Now we all know that the micro:bit can make noise either with makecode or Python but out of the box its quite a quiet little thing. Luckily you can use some crocodile clips to connect a pair of standard headphones or use the amp:bit but these keep the

micro:bit and sharing sensors with a Raspberry Pi

"Can a Raspberry Pi use the sensors on a micro:bit?" This was the question that was asked whilst sat in the pub the other evening. A few evenings later a micro:bit was connected via i2c to a Raspberry Pi and i2cdetect was ran on the Pi: pi@raspberrypi:

micro:bit and searching i2c

Whilst this is more of a bookmark for myself it may be handy for others who are playing with the i2c bus. If your unsure if the i2c device you have connected up is working then it's a good idea to scan the i2c bus and see whats available. The

micro:bit and the blue micropython

One of the more interestng parts of the micro:bit is the bluetooth module. With this its possible to, amongst over things, flash the device and also control external bluetooth devices. However due to various technical reasons this built-in Bluetooth functionality is not available when using micropython. However its possible

A few notes on I2C and the Picon Zero....

Picon Zero is an Intelligent robotics controller for the Raspberry Pi. A built-in processor handles all the direct communication between the parent controller and any attached devices and motors. Whilst primarily an add on for the Raspberry Pi, due to it using I2C for communications, it is possible to use

micro:bit and fusion (sort of) power...

micro:bit and the Bit:2:Pi

During a previous experiment in getting the micro:bit to talk to 4tronix Piconzero it was suggested that the 'jumper wire lashed together' micro:bit dev board and Pimoroni Black Hat Hack3r could be replaced by a purpose built board which would allow the micro:bit to talk to Raspberry

Files on a micro:bit?

Some ideas require that small amounts of data be saved for future use. It would be ideal if this was possible on the micro:bit. MicroPython provides the tools to allow this. MicroPython is an implementation of Python 3 that has been developed to run on microcontrollers with a version
