Me and my brother have been working a lot on some flite test planes, www.flitetest.com/
printing out plans, building, and giving them cool paint jobs. The first plane is a piper cub style plane (top) with a 40'' wingspan, painted to look like dusty crophopper from Pixar's planes movie, and I got him to fly a little! (still not a very good pilot) I added some fun "bombs" made of foam board and Nerf rival ammo, and then a servo motor (blue) that releases the rubber band, letting the bombs drop. our second and most recent plane is a plane called the flite test sparrow, (below) and it has a 30'' wingspan. we replaced the opaque hatch with a transparent one by cutting out a window shape, then laminating, and cutting the window out. we then used permanent markers to make some designs.

here in Nebraska we get our share of snow, s0 I decided to build a motor powered, boat looking, sled. in my first version I had a very weak motor and a heavy battery, so in version 2 I swapped those out. with lots of design help from my brother, ( who drew the windshield wipers) the key features are: Lego man seating, dual snow skids, zip-lock bag electronics waterproofing, cool paint job, and the same power system (battery, electronic speed controller, motor) as the jet in the video below. it takes a bit of throttle to get going, (high friction) and it capsizes easily, (high center of mass) those will be things to fix in version 3. video of jet: na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fvimeo.com%2F659096803%3Fref%3Dem-share&data=04%7C01%7C%7Cad4a72a5600f43106e2908d9cefa4345%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637768396525399605%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=D%2BrJgygPjb9GF3nlg6K97U6pLuunRVeFCys%2Bh%2FzL3Go%3D&reserved=0 pic of sled.

recently Ive been designing and building a new plane designed after the brittish de havilland fighter. so far I haven't put any servos or electronics yet but the foam part is done. a few features are the opening nose, and the elevator and ailerons, instead of just elevator that serves the job of both. so it should be more stable.
my r/c model airplane is basically complete! (I just need a new electronic speed controller.) so I was ready to do some throw tests, where you throw it and try to get it to glide. (this helps check balance, flaps, and other things.) it soared up and then plummeted down. (very bottom) back to the bench! top: airplane pre-tests. bottom: airplane post-tests.
I've been working on remote control model airplane and it's been fun and tricky to get all the servos, flaps, and electronics to work. I've been making it out of foam board that has paper on both sides, and then hot gluing the pieces together. for the flaps I've cut out pieces of foam and the taped them on flexibly so the servo (blue) can still move it. it's fun learning more about aerodynamics, electronics and other cool airplane things! above: the rear segment of the airplane.
filming will be starting soon for the new lego stop motion: bricktown. bricktown is my adventurous attempt at making a "Seinfeld" lego stop motion. stay tuned!
!recently I've been learning some python turtle graphics to ( or at least try to) make some neat pictures. turtle was born sometime in the 60's as a logo designing platform that you could use just by typing "import turtle" in your python program. the picture below was made with the background color blue (coded turtle.bgcolor("blue")) and the pink part is where it makes a circle and then turns 80 degrees and makes another one 100 times, to look like a flower!
I'm building a tamiya rc car tt-02 chassis with a 1999 subaru impreza body and I'm learning a LOT about differential gears, suspension, and steering. (this one uses servos to steer which are used on model aircraft too, they lift the elevators and flaps and things.)
recently I've been working on a interactive program, so when you run it it will ask you questions. in this program it asks questions about your model rocket, like weight, thrust, impulse, and others. after you enter the specs I've coded it to take the specs and insert them into formulas for acceleration and average thrust. I'm still working on it and it's fun to learn more and more coding!
I have been working on a bird feeder cam that could take a picture every three seconds and then string them together into a faster moving slide show to count birds, or what hours they eat, under what conditions and other things. I am programing a raspberry pi (credit card sized computer) using python (programing language that's open sourced ) to get a raspberry camera to take a string of pictures.
