If you are using phone, you can watch it directly through youtube:
It all started when i found a module that can display big images on a
screen. I ordered it because I wanted to see how it works. After a while i didn't know what to do with that, until i got the idea to prank a friend that my calculator can do more then he thinks. I contacted with the guy that created this board, and asked him to create a keyboard with custom parameters. Happily, he agreed and here is the result. I tried to be as detailed as i could in the video to make it easier for anyone who wants that also.
All you need:
- Free 40 minutes to build it.
- Broken calculator
- Full kit from syspearl.com ( Firecrest board + keyboard + cables) Screen size is about 7x5 cm, it will fit in most calculators
- Micro sdcard
- 2 button batteries
- Zip tie
Have fun :)
