My good friend Wayne NB6M has kindly loaned me his Minima-like build using my controller shield for the Arduino.  His front panel is very si...

I have implemented changes to the Minima controller code developed by Eldon Brown (WA0UWH) and others to use the second Si570 on my contr...

Well, I am not certain yet how I am going to mount things in the long run, but for now I have stacked the display, Uno and Shield on the bac...

This evening, I hacked poor Wayne, NB6M's Minima to accept VFO energy from my Minima Controller shield.  As a first hack, it worked fine...

I have tested my Minima controller successfully for support of 16x2 or 20x4 LCD displays using a 5V i2c backpack .  Here is a 20x4 display r...

Last evening I placed my second Si570 on my Minima Controller shield and am pleased to see it is functional as well. The datasheet for t...

UPDATED: As was intended, programming of the controller shield is trivial.  A single additional class was required and no changes to other...

UPDATED: My Minima controller Arduino shield checks out as functional.  With two Si570 devices on the board, powering them from the Arduin...

I have completed (as far as I went) the build of my Minima Controller Shield, but have yet to complete testing of the board.  I populated on...

I finished up the Si570 shield for the Arduino today and sent the gerber files off the the fab house today.  They will be on the panel to be...

I have integrated my keyer code that was originally developed for the Propeller hardware and ported to the Arduino with the Minima firmware....

I have built one of the fine data logging shields for Arduino from the fine folks at Adafruit  to further clean up my beacon project rats ne...
