All your dreams come true


Posters spotted. Just keeping the eye trained, or more obeying it's demand to capture despite numerous glances of consternation.

Matchbox Microphone


From Home Inventions book (DK publisher), Matchbox microphone.

The graphite in the lead conducts electricity from the battery through its carbon atoms. Had a quick look up but think the graphite has a covalent bond which hold together in layers connecting 3 carbon electrons of a atom and so leaves a free carbon electron to move like the loose electron does in a copper atom. This is why it conducts.

The loose piece of lead from a pencil which lays across the two other lead sticks conducts but can move if you good it and so you get this break in circuit and change of current and sound of the air being blown as it rolls. 

Had crocodile clip wires, split a pencil or two as they kept break and gaming too short to go across a matchbox. Was cool. Hooked up an affordable oscilloscope (jyetech d1... something) to visually see the sound and change in current. 

Hive Game on a Walk


Having a play of the cool boardless game of Hive, outdoors on a bench. Great portable game with simple rules a few pieces to remember but good fun. Read previously someone describe it a little like chess. Great nonetheless.

Potter Bridge Entrance


Some graffiti under a disused bridge saying enter, made me think it was a portal like some kind of AR or magic entrance like in potter with 9 and 3 quarters.

Renewables At Home


Renewables with home schooling during the current climate. Then went on to pin, or blue tac laminated pics of what products and foods come from around the world on a wall map. 

Sure there will be much more learning but it was fun then guessing what the pictures of different plants gave us that we eat it use.
