<p>This is a tiny clock built around a small OLED display.</p> <p>Easy build in just an hour or so!</p> <p>Things you need to buy:</p> <p>0.96" Inch I2c IIC Serial 128x64 Oled LCD: <a href="http://a.co/1urMxg3">http://a.co/1urMxg3</a></p> <p>Things from Adafruit:</p> <p>Breadboard-friendly SPDT Slide Switch - 805</p> <p>Adafruit Pro Trinket LiIon/LiPoly Backpack Add-On - 2124</p> <p>Adafruit Pro Trinket - 3V 12MHz - 2010</p> <p>CR1220 12mm Diameter - 3V Lithium Coin Cell Battery - 380</p> <p>Adafruit PCF8523 Real Time Clock Assembled Breakout Board - 3295</p> <p>Lithium Ion Polymer Battery - 3.7v 150mAh - 1317</p> <p>Total cost like $50</p> <p>You'll need to mill a small PCB - but wires could work too. It's pretty minimal.</p> <p>You'll also need to print the enclosure if you want. I chose not to do a face plate but it might look good with one, depends what you like.</p> <p>I would have gotten the Adafruit OLED but they didn't have them for sale at the time so I went with <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a>. As far as I know the Adafruit one is not going to be compatible with this but I haven't checked.</p> <p>The code is pretty basic.</p> <p>The battery lasts 7+ hours and probably could be increased a lot with some tricks to save power.</p> Category: Electronics
