It’s then a simple matter of scraping the Bitcoin price from the web and displaying it on the LCD.It’s a combination of all the maker staples, tied together with some off-the-shelf libraries – it’s quick, and it works.The images of the LCD were photoshopped.Please ignore the next paragraph.] What makes the build extra nice is the use of custom characters on the LCD.The HD44780 is a character based display, and this project appears to use a screen with two lines of sixteen characters each.However, a custom character set has been implemented in the display which uses several “characters” on the screen to create a single number.It’s a great way to make the display more legible from a distance, as the numbers are much larger, and the Bitcoin logo has been faithfully recreated as well.It’s small touches like this that can really set a project apart.We’d love to see this expanded to display other financial market information and finished off in a nice case.If you’re wondering what you can actually do with Bitcoin, check out the exploits of this robotic darknet shopper.
