How I spent my Summer Vacation

I remember in the 5th Grade, at the beginning of the school year we were tasked with writing 500 or some such words on that very subject. I didn't like the assignment, perhaps because I didn't really do anything that I thought was noteworthy. I do remember listening to many faraway lands on Knight Kit and Magnavox Shortwave radios, plus looking at the Stars and Planets with my trusty Tasco Telescope.

But this year was way more fun than that!

I built this small footprint Data Acquisition System.

• 32 Bit MCU @ 250 MHz with Floating Point Unit

• 5 x 16 Bit ADC's
• 3 x 16 Bit DAC's
• 3 x DDS Chips

• +/- 1 Amp Precision Current Source 
• 6 Analog IO Pins
• 8 Digital IO Pins

• Thermometer + Barometer
• Real Time Clock
• Onboard EEPROM

• MicroSD Card for Data Logging

• 6-30 VDC Input Power @ 1 Watt

• Reduced 2 x 4 Inch Footprint
