Scratch

I think I'll get one for Christmas. This should have more than one page by now!


Oops, nvm. I just made a 2nd page.

Right....ultimate power...uh huh.  No, I'm not sure why, I can sticky on other parts of the forum, but not on the Sensor Board area.  Another of life's mysteries!

wow.. this is getting really off topic...

That was actually posted way back in 2008, when I was just a wee Scratch user!

Dear Chalkmarrow,
I am a middle school technology teacher using Picoboards with my 7th grade students. We would like to use the slider function in a game of Pong where the handle is moved by moving the slider. We are having problems because the slider does not seem to go to the  negative numbers on the screen, therefore only covering half the playing board. Not ideal as you can imagine. Can you please help? Any assistance would be most appreciated.

If I'm correct, the slider outputs a number from 0-100, correct? So for controlling the handle, I would firstly subtract 50, so the values could only be from -50 to 50. Then, I would multiply it by 4.8, so the range would increase from -240 to 240. Like this:

[blocks]
<set x to(  ((  ((  <{  slider value  }>   <-> 50  ))   <*> 4.8  ))
[/blocks]

Kind of rough looking, but I think that should work.

download url not working

I figured out a problem with PicoBoards. You can't have multiple projects using the PicoBoard open in Scratch at once, otherwise only the project first opened works.

Do we have a complete Programming Code for the Scratch board especially the serial communication part? links given seems to be broken.

Here it is.
ScratchSource SensorBoard Code

Just a thought: Is it possible to make your own PicoBoard?

There is an assembly kit named NanoBoard. (karenb has one.)
It's 1500 yen ($20). Over 20 kids successfully soldered it in Japan.
If you're interested in it, I can support to export it.

I sure hope the price goes down soon. D:

I have some scratch boards which I got a long time ago, which were working fine until I upgraded to 10.7 on my macbookpro. Now, I can't get scratch to show any sensor board readings. When I try to select the serial port I am able to select /dev/cu.usbserial; however, the drivers I downloaded from prolific say that it should be /dev/tty.usbserial.
The latter is what is listed in the Terminal.

How do I do this? I fel there is something I'm not doing!

I really want to use the scratch boards for my projects with kids I work with. Any help is greatly appreciated.

I have also tried the FTDI serial usb drivers and none seem to work.

Thanks in advance.
