I’ve been messing with my phones features, and I’ve had ideas in my head about how i could use the sensors on it, so it got me thinking about new technologies, or ideas that could use those sensors to do interesting things. Haven, (an app i found while browsing f-droid) uses the sensors in a very interesting way, it can detect whenever the phone is moves, if theres a loud noise in the room, and other cool things, the point of it is to secure private spaces. This is a practical use for the sensors on a phone. It could also be used in creative projects as a trigger, such as a light being switched on, the phone then turns on the heater automatically. (I wish i could be like Mike Rober, and build anything i wanted.) (Picture kinda related)

It would be easy enough to purchase the primers for barcoding, but if the technology to make them at home also becomes accessible I am all in!
The method you describe is a bit too resource intensive because you need to tailor the primers specifically for each species. A huge advantage of DNA barcoding is that the same PCR primers can be used to barcode a very large number of different species. So, I will be able to purchase a single pair of vials with the reverse and forward primers to do sequencing. In DNA barcoding one gets the PCR primers that flank a region that shows little variability, such as a ribosomal sequence or the cytochrome c oxidase sequence. This sequence is then amplified and run a database search on it to identify a species.

You did bring “biohacking”. Do you happen to know if that movement is still active? I joined one biohacking meeting a few years ago and it was a very exciting concept, but I got distracted and didn’t keep up with it.
