Inside the prototype’s 3D-printed chassis is an Arduino that runs the show — it adjusts the machine’s temperature with heaters and fans, controls the excitation light, and handles the wireless connection with the iOS device. Meanwhile the iDevice’s camera is used to detect how luminescent those target DNA sequences are, and the corresponding app checks to see how closely they match the signature of whatever disease you’re looking for. The current version of the hardware isn’t quite as polished as the team would hope and it’s chock-full of open-source, hack-friendly components, but co-founder Marc DeJohn says they’d like to keep it that way if at all possible.
The team is aiming to sell its initial run of smartphone-centric PCR machines for about $1,000, but that’s just the start — should they get significant traction from the medical community at that price point, Biomeme wants to try and bring down the price to the level where you average curious consumers could pick one up without breaking the bank. That’s the overarching goal here: to democratize DNA testing.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
