Electronics Production Assignment Week of February 17, 2014: The goal for the week is begin the process of creating a FabISP, to mill a board and stuff it. |
|
1. Unhappily, there were problems for days deciphering how
to get the computer to talk to the Modela. Multiple
conversations between Jonathan and James and Shawn resulted
in success through Super User. Much of our knowledge growth
curve is developing through trial and error and more trial
and more error, which ok too. |
2. An initial board was only superficially incised. The
bit needed to be bumped down further. Another board had the
traces etched and was ready to be cut out. The bits were
changed, the interior png switched to, the z axis changed,
and the directions sent. Oops. The Modela continued to
create traces because one needs to hit "make RML" before you
"send." We also need to experiment with cancelling out a
program that is running. |
3. Having used up a row of material, a new x and y axis
were set and another board attempted. This time, the milling
was too close to the edge of the material. I tweaked the x
and y and broke the bit when setting the z axis. |
4. I changed the bit, changed the x and y settings, set
the z axis and nothing wrong happened. Then I changed the
bit again from the 64th to the 32nd, selected and loaded the
interior.png, hit make RML and sent it. Success and much
knowledge gained. This is my milled board fresh from the
Modela: |
5. Happily, I had learned how to solder two weeks before
when I attended the Fab Lab Arduino workshop. The task for
the weekend is to stuff the board and continue to learn. |
6. But of course, I am a novice. Soldering the mini USB is
indeed where one will break the board. As long as it was
broken, I used the board to practice a few more contacts. |
7. My former student Mason is now fourteen years old and
can be seen soldering next to me in the photo above. His
board is functional. We have become partners and officially
traded roles as teacher and student. As an educator, that is
actually a very positive accomplishment. I hope to have my
own board milled and stuffed by me by the end of March. Mason's FabISP |
8. My newest circuit board milled Sunday, March 23 with
two components soldered. Onward! 9. April 23 - my board milled and stuffed. Mickie Flores Home |
