Self Watering Plant, Part 1


Just begun assembling and preparing the parts for what I hope will be a self watering plant mechanism..


Stage 1: take delivery of a battery-powered water pistol, then open it up..









This base was able to provide 3v and 4.5 v as well as having a useful switch and speaker point.

The connector block is to simplify connecting it up to the Pi / Microbit / Circuit Playground Express




First comes the opening up, then comes the moment of truth: has it got potential for inclusion into a new project?

Consideration must be given to the old battery / leaked battery / corroded connectors scenario as well as the voltage that it will be happy to operate with..



tinfoil is a great help..





Time to reveal the toy collection

There is a distinction between where a child’s toy meets a tool meets a gadget, but there was no need to draw that distinction in today’s Year 11 Computer Science class. After a brief introduction I threw open the wooden toolbox (from Sammy’s Garage – just the thing..) to reveal a smorgasbord of delights awaiting connection and coding up.



Scrap Store – the fun begins!

For great value electronic kit (broken toys for the most part) Scrap Store is hard to beat.

Now for some dismantling and corroded battery removal.

 I had some help making an initial assessment of the loot..

Note a startled expression when the dog sat up and barked.!


1st day of {Secondary} school

Left for the start of my Secondary adventure this morning having watched my son bond with Big Trak – tis time for his father to ensure that he can stay one step ahead!

My thanks to Lydiard Park Academy Trust who gave me a perfect welcome today. The IT / Computing team are brilliant – seamless in their vision for excellence in delivery of this fabulous subject. Looking forward to teaching tomorrow – feeling a welling up of excitement that the time has come to focus on one subject – and to be able to explore that subject alongside a truly great team.
