Are you a Bitcoin miner or trader, but find yourself lacking the compulsive need to check exchange rates like the drug-fuelled daytraders of Wall Street? Fear not – you too can adorn your home or office with a Bitcoin Price Ticker! The post is in Italian but you can read a translated version here.
It’s a straightforward enough build – an Arduino compatible board with an onboard ESP8266 is hooked up with an HD44780-compatible LCD. 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.
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. Oh, and Microsoft will take them, too.
