Blogs / Programming with the kids
« Last post by Dragon on January 14, 2017, 16:30:42 »
My oldest kids have started programming in Python at school. I think it's really cool. I was showing some stuff to my daughter and had suggested using rainbow colors for a circle. (Originally, I she was drawing multiple circles, with different colors for each one, but the words came out a little different as I was leaving the room.) My son took up the challenge though and came up with this... which I just had to show off...

Attached is a screenshot of the end result... he said it's not perfect, but I told him he can update it, but this was great. (This was done on repl.it.) I'm going to challenge my kids some more with this...

Code: [Select]
import turtle

t = turtle.Turtle()
t.speed(100)

for i in range(11):
  t.pencolor('red')
  t.forward(10)
  t.right(5)
for i in range(11):
  t.pencolor('orange')
  t.forward(10)
  t.right(5)
for i in range(11):
  t.pencolor('yellow')
  t.forward(10)
  t.right(5)
for i in range(11):
  t.pencolor('green')
  t.forward(10)
  t.right(5)
for i in range(10):
  t.pencolor('blue')
  t.forward(10)
  t.right(5)
for i in range(11):
  t.pencolor('purple')
  t.forward(10)
  t.right(5)
for i in range(10):
  t.pencolor('pink')
  t.forward(10)
  t.right(5)

Video Games / Oregon Trail

I just found this online version of the classic Oregon Trail game! There are a bunch of other old games available on archive.org, but this is the only one I've tried so far.

My first try (recently anyway... I had played the game long ago), I completed the trip to Oregon and got nearly 2400 points.

If someone loses a Nikko remote control, this can helps:

Look at the printed circuit inside the car (receiver) and see the reference of the decoder i.c.

Done

Hi Korreka, I can't see any of the images that you've linked to, but I'm able to see the datasheets that you have linked to Google Drive. You could try uploading the photos as attachments to this forum.

Thanks for posting. Unfortunately, I can only see one image of the ones you posted above, just the one with 2-Channel Lancia Stratos in the upper left.

Tamiya qd has the same PWM (digital proportional) radio control standard as Nikko or Futaba but the steering and propulsion controls are changed. I own a Tamiya QD SuperSabre that has the same electronics as your RC car.

You can test the Tamiya QD remote control with a Nikko proportional digital car with the same frequency crystal.

The remote control has an L9362 encoder:

The car has an L9367 decoder:

In the "out" pin of L9362 encoder, you must have a signal like this (seen by a osciloscope):

I do not find the technical sheets of L9367 decoder but it should look like L9363:
