PiHut Codemas Advent Calendar Day 9 - Raspberry Pi Pico and a tilt sensor
In today drawer, Pheobe found a tilt switch sensor. We connect this up to the Raspberry Pi Pico,and try out the example code, then turn it into a trap for Jon to investigate.
We also now have the start of a neat little musical library for use with Micropython on the Pico.

I review two microscopes I tried out for my lab, and for some fun.
First up is a SuperEyes B005+ - a 200X handheld microscope costing £35 - which had a cable problem.
Secondly I review a MAOZUA 5MP 20x-300x microscope - handheld or with a stand, which cost £53 and seemed to work reasonably well.
How well do they work for peering at electronics, and for odd stuff like the weave of clothes?

We've moved - including the lab. This is a quick tour of the new Orionrobots lab, presented with Jonathan (6 years old).
* 3D Printer: RepRapPro Ormerod 2
* CnC Milling Machine; A 3020 with a controller similar to the YooCnC.
The cupboard and shelvign units are both from Ikea. The shelving unit is a modified Kallax TV arrangement - quite nice how the tool board fits there.

This is the fourth day with this electronic Sound Advent Calendar. This solderless breadboard kit builds into an electronic synthesizer circuit.
I open the fourth window in the calendar, which gets me a speaker.
I hook it up, make a small sound with it and explain the circuit operation, along with the basics of speakers for electronic sound.

The Orionrobots Lab gets a new Oscilloscope. It's an oldie but a goodie, the Rigol DS1052 E.
This is intended for use in our robotics projects, for looking at PWM signals along with I2C and SPI stuff, power supply ripple etc.

A short while ago I bought an Electromagnetism child's science kit. This looks like a great experimental toy for showing kids STEM skills but is also a lot of fun for me to experiment with electromagnets myself.
I open up the kit, take a look at the parts, the manual, and do some preliminary experiments building a circuit with its components, using a motor as a generator with an ammeter.
I will be incorporating and using this physics lab kit for further experiments with electromagnets, compasses, and a magnetometer.

Following my last video playing with a bag of compasses, I had some ideas and some requests. A viewer asked me to try making a small electromagnet with 10 turns, and experiment with this and the compasses. I made 2 more electromagnets - a 50 turn metal core coil, and a 110 turn hollow magnet.
I also try getting them to move another magnet.
I also smell burning at least once!

In this video Helena and I take you over the Pi camera mount we created in Fusion 360. The mount is designed to go onto a 4tronix Initio board when combined with a bracket. This will go on my tank tracked piwars 2018 robot.
This was the first print, and we did have to refine it later.
Fusion parts:

Bottom Front Plate: https://a360.co/2Cx1wEq
Back brackets, side plates: https://a360.co/2Tc1NlI (I got lazy here, put many components in a single file)
(2018 update - the screw mount ribs need to be deeper - all of these sheared off at the screw mounts)
