First DIY pcb |
........August 21, 2011 |
 |
Learning how to make pcb using simple tools and a laser engraver...
First attempt was not quite there.... painter over and try again.
Second attempt looks great... clean and accurate...!

Prelimary PFD Panel Cut |
........August 7, 2011 |
 |
First preliminary test cut of the PFD panels. Found several minor adjustments that are necessary...
Most notable, the planned pcb will is not removable as intended!. Further, There are some minor alignment issues.
However, the micro servo, driving the slip indicator ball, fits great!

Testing Box/Panel |
........July 29, 2011 |
 |
Worked up a few testing or prototyping boxes for working through the verious board to board comms...
Still do not have a hard and fast plan for the I/O, but his should help shake out some of the hurdles.

Have an I2C data bus working. The primary or master Arduino sends data to the slave allowing for movement of
a servo corresponding to the flap indicator setting.

Prelim I/O Board Layout |
........June 16, 2011 |
 |
There are numerous Arduino options with varying pin layouts and numbers. So is it better to maximize the number of
inputs from a single board or nimimize the workload per board and use more linked boards? That is what we will be determining in the weeks to come.

Cut Diagrams EICAS (pdf file) |
........June 14, 2011 |
|
Posted pdf file for assembly of the EICAS panel. I left the same series of buttons as is shown on the MFD.
Obviously, you can omit these if you would like.

Cut Diagrams for MFD (pdf file) |
........June 13, 2011 |
 |
Posted pdf files showing the cut and assembly layers of the MFD panel, and updated the PFD.
Also includes a PCB diagram for simplifying the wiring and connectivity. More to follow.

Debouncing a Switch |
........June 12, 2011 |
 |
Simple diagram showning the use of a logic inverter to debounce a switch. When using
interups on the Arduion boards, software debounce isn't an option. This logic inverter is a
very simple, cheap and effective option.. 74C14 Schmidt Trigger

Video of the Arduino Mini |
........June 7, 2011 |
 |
The mini is only slightly larger than a postage stamp but has all of the features and computational power of the
larger boards. While the number of accessable pins are few, there are compelling reasons to be familiar with the mini!
