This Thursday's (4/22/04) crafts session is cancelled because the tech center's new floor is going in. See you next week!  --Amy.

This Saturday 10-12 I'll be at SETC, to show how to make and program
a microcontroller board.

The hello-world board:
   hello.sch
   hello.brd
   hello.cmp
   hello.asm
   tn15def.inc
   hello.hex
   rx.py
   fuser to check /dev/ttyS0
   check cable
   to set port: stty 9600 raw -echo crtscts </dev/ttyS0
   move x y
   move hello.cmp in cam to x y
   contour, raster, write toolpath
   move Modela head to bottom of range and back off ~.25"
   drop tool to surface of board
   cat out.rml > /dev/ttyS0

There will be a meeting at MIT in the Life Long Kindergarten area
of building E15 on Friday 3/5/04 at 11am to discuss craft making
at SETC Fablab.  Please join us!  --Amy.   (amys@mit.edu)



2/2/04

For the Saturday morning session 10:00-12:00 on Feb 7, we will be joined by
Robert Baafi and Yaw Twum Sakyi to discuss possble fab lab plans in 
Ghana, as well as by David Cavallo who has been working in Senegal,
and Bakhtiar Mikhak who helped launch the fab lab program. I'll also
aim to have a demo ready by then of making a microcontroller board 
there.

I added a command to site.py so that it now automatically saves a
backup (RCS) copy of edited files.

Here are the links from last Saturday's demonstration:
   AVR instruction set
   ATtiny15L microcontroller
   AVR assembler mnemonics
   AVRA assembler
   GCC/libc compiler
   UISP in-circuit programmer
   tx.asm: sample program to transmit serial data
   rx.py: sample program to receive serial data
   cam.py: CAM program for fab tools
   cad.blend: CAD extensions for Blender


There was also a question about getting the lasercutter to cut
continuous paths if a file was not drawn that way; that can be
done by using cam.py to contour the shape.

An earlier question was about network connections:
   "ping www.mit.edu" tests for connectivity to that address
   "ifconfig" show the current network configuration
      (make sure there is an IP address listed)
   "pump -i eth0" gets a DHCP address for an ethernet interface

Hey John Pope:
Be sure to check that the second computer--
the Dell that runs the Epilog cutter is turned on
and connected as well.  If that one isn't running,
then the Dell that Neil demo-ed with won't connect.
Hopefully that will help you...

Ack! I seemed to have erased all older notes. Will have
to get Neil to repost info. Sorry about that.

Reminder that Mel tells us that the junior designers will
be at setc on Sat. January 31 at noon.

Will get Neil to repost info ASAP.  Sorry about that!
