The Design
The Working
Read moreI was asked by Blockchain Village founder Ajit to make a badge that represents his vibrant cryptocurrency and blockchain community and gamify a thing or two in the process.
It wasn't too long before I could draw inspiration from old school gaming consoles with the display. I was asked to consider 3 key characteristics:
- Wearable: Users should be able to wear the badge on their wrist.
- Crypto Puzzle: An engaging puzzle based on the ancient cipher.
- Reprogrammable: The badge should be easily programmable again and again.
After experimenting with few form factors, we finalised a horizontal design this time with lanyard cutouts on the top and bottom part and tactile push-button keys on both sides.
That brings us to one of the most sophisticated and elegant designs we have ever made on a single-sided PCB.
Experimenting with the PCBs with few colour combinations bought us a couple of beautiful looking blends. White base colour with Blue personality and vice versa.
And so we settled for the White design with a Blue personality.
After sliding the switch on the top right corner, the badge boots up in the Blockchain logo animation and event details. If you're one of the selected special badge holders, it will also flash your name and designation on the display.
Making It Wearable:
Insert the lanyard from the top cutout then all the way to the bottom cutout - wrapping around your wrist and then back to the top cutout. Feel free to experiment and adjust the lanyard accordingly.
Puzzle Mode:
Press and hold the S1 key for 4 seconds to launch the "Insert Code" mode. On this screen, you can enter your puzzle binary which will lead to the next screen with further clues into the challenge.
You can clear the binary input with the S2 key. Keys to enter binary are on the right side of the badge. The badge responds to the binary automatically as soon as it receives all the (right) binary.
Reprogramming:
All badges are equipped with male headers and pinout for reference.
The only thing required to program the badges is jumper wires and ISP Programmer. Attach the Jumper wires from their corresponding pins to the ISP Programmer connected to the system.
Launch Microchip Studio to program the badge. From there, you can edit the following code or make your own build from scratch.
Once that's done, all you've to do is upload the hex file to the ATmega32A. You can use Microchip Studio if your ISP programmer supports it. If not, there are many third-party softwares available that'll push your code to the ATmega32A.
The Code
The code provided here has some additional features than the one flashed by default on badges.
We wrote all the libraries required from scratch. And were able to make the badge more fun to look at in the process with plenty of font and animation experiments.
This code provides one extra font that users can utilise to showcase all the funky art they want on the display.
There's also a portion of code dedicated to serial communication. Users can build it as per their use to utilise serial communication and maybe, just maybe, at some point it has to do with the Rx-Tx pins on the badge.
Since this code is provided openly, we've removed the badge puzzle from it. So, if the conference is on and you wish to participate in the Blockchain CTF, make sure to not flash your badge with this code until you're done with the CTF. Meanwhile, we've provided a very quick way to flash the badge with the user name. Just replace the highlighted text with your name and designation.
With that said, I look forward to all the crazy experiments that curious minds will do with this badge.
