Anybody remember making these



Made a few last night with my eldest, Great fun racing them up and down the table.

Now if i could transplant the old K series with one.

Often wondered why no ones made an assited engine using the PIEZO CRYSTAL

For those who dont know the uses of these, they are found in lighters, if a small hammer hits the crystal an it reacts by giving off an electric charge

or

the likes of epson found the crystal moves when a charge is put through it, an made them in to very fine print heads

but how about this as the car moves along a small army of these could charge batteries, the batteries could then power an axel ie the front so you have a four wheel drive F........ A Hybred F'er

Wow, I remember making one of those when I was about 6!
Of course the cotton reel was solid wood and the match was 'used'.(for safety)

I also remember deciding to make one without supervision. I knew I wasn't supposed to play with knives - so I took a razor blade out of my dad's safety razor and used that!

Guess what - I've still got the scar where I almost took the top of my middle finger off!

They use Piezo crystals as motors in camera lenes and some mobile phones called squiggle motors
here's one


And the space shuttle has giant ones in its delivery arm

Guess I'm way ahead on my thinking again ehhhh.....lol

I was thinking slightly charge the battery to use them while going along......and boost charge the battery from braking

I had a hunt an you can get actuators an everything with them


A small motor with big magnets round it pointing outward with opposed poles so it keeps it spinning once moving

With the TF's suspension, should produce enough shocks and vibration to power a small town
