Edison adapted Obi-Wan's Jedi Interceptor

Took a little bit of working out for how to make the wheels turn cogs to push the wings sideways, as opposed to the jaw on the Oocher & the Cyclops Edison lego model, which was in line with the direction the wheels turned.

The whole wing couldn't go up and down from the weight, might try it on full power to see if it can push the whole wings up and down, but looked good with only the front part/half.

The Edison can line track, so plan to have it following my 5 years olds own drawings. Not too expensive the Edison, much cheaper than lego's MindStorm and probably does as much as that can.

With the lego it was strange to make the logs line up I had to sort of shift the studs from the actual Edison by using the LEGO Plate 1 x 2 with 1 Stud (with Bottom Groove) (3794) and other parts.

The 'cockpit' that houses Obi Wan still opens, just had to shrink the wings slightly, still looked good.

Used the parts from £19.99

Will post again when video the line tracking.

Oocher & The Cyclops with Edison

Slowly working through this, will share a video of it in action soon. Lego cogs make the mouth go up and down powered by the Edison. Took a little working out how to feed the turning of the wheels to open the mouth up and down.

Looking to make the instructions and ebook download, took some photographing of it construction, sure there must be easier methods to making instruction sheets.

Ultrasonic Anenometer

Here my early tests for making a wind sensor out of cheap, accurate hcsr04 ultrasonic sensors. Made 2 opposite each other for wind speed, progressed to adding another 2 to read all 4 sensors bouncing back and forth to each other.

Tried to calculate the wind direction with sending the reading into processing, need to stabilise the structure a little more and test again as we couldn't quite get a definitive angle to point one way or another.

Looking at this and other links as we progress.

8 year old nephew made this. pretty cool.

Tsuro Board Game Tweak

Tweaked the pieces you use in Tsuro: game of the path by letting my little one use lego instead. Still didn't quite get into it, little bit older he might like this game.
