 638 | <description>&lt;h3&gt;SparkFun Electronics' preferred foot prints&lt;/h3&gt;

 640 | We've spent an enormous amount of time creating and checking these footprints and parts, but it is the end user's responsibility to ensure correctness and suitablity for a given componet or application. If you enjoy using this library, please buy one of our products at www.sparkfun.com.

 9 | ## Short description
10 | A retro watch, based around the HP QDSP-6064 Bubble display, used in 70s HP calculators like the [HP-35](https://en.wikipedia.org/wiki/HP-35). The display is controlled by an Atmel ATMega328P-AU MCU with Arduino code, and the time is kept by a Maxim DS3231 Real-Time Clock module, that stays connected to the LiPo battery at all times, keeping time even when the microcontroller and display are not powered.
11 | The code is open source, licensed under the MIT License, and the harware is fully open-source.

18 | ## Hardware
19 | ### PCB
20 | The board design was made in Eagle, has been tested and works. A 500 mAh [LiPo Battery from Adafruit](https://adafru.it/1578) fits perfectly under the board. It can be freely modified. It can also directly be ordered on the OSHPark website:

22 | 
23 | (DISCLAIMER: I am in no way affiliated with Atmel. I just put the Atmel logo on the PCB to show the circuit uses an Atmel chip, which I really like !)
24 | 
25 | ### Bill Of Materials
26 | You can find the BOM [here](https://github.com/RafaelRiber/RetroWatch/blob/master/BOM.md).
27 |   
28 | ## Software
29 | The software was written in Arduino code, is licensed under MIT License, and can be uploaded on the microcontroller via ISP.
30 | Be sure to set the desired time in the code prior to uploading, to set the time registers on the RTC.
31 | 
32 | Functions of the code include:
33 | * Hours, minutes and seconds
34 | * Day, month, year, day of year, day in week, week in year.
35 | * Stopwatch (start, stop, reset)
