Celebrate the second dose of vaccine [Paul Klinger] Combining our two favorite things-flashing lights and wearable technology- Create a great mRNA vaccine badge.
The badge is designed to be worn like a pendant and will flash slowly within 10 minutes, passing through all 4,000 nucleotides of the Moderna vaccine. Watch the video after the break to see its actual effect. If you get a Pfizer vaccine, don’t worry, you can switch to Pfizer’s mRNA sequence using the interface button on the back of the badge. There is even a handy legend on the badge to identify lipids in case your microbiology skills are a bit rusty.
On the back of the board, you will find some current-limiting resistors, a CR2032 battery holder, and an ATtiny1617 microcontroller that runs everything. To assist in the conversion of mRNA sequences into LED pulses, [Paul] Wrote a Python script that will automatically import nucleotide strings from the standard .fasta File and store each nucleotide in only 2 bits, allowing the entire sequence to fit in the microcontroller’s program memory.
this is not [Paul’s] The first RNA-related project; he initially developed the aforementioned Python script to compress the entire COVID-19 sequence containing more than 30,000 nucleotides into the program memory of his Virus Blinky project, which was our last year feature.
