My recent projects have revolved around interfacing a Raspberry Pi with the physical environment. Sometimes, the Pi acts as a receiver, with temperature, humidity, ultrasonic, or IR sensors; sometimes as a transmitter, with an IR emitter or a printhead. Sometimes, it runs a web server, yielding an “internet of things” device. The specific devices I have built are,
- HydroPi, a hydroponics system based on the Raspberry Pi.
- Paparazzi bird feeder.
- RaspAC, a Raspberry Pi AC controller.
- Bioprinter for printing cells onto Petri dishes.
I am an occasional contributor to the special functions module of SciPy. I wrote the current implementation of spherical Bessel functions, and am working on and off on a better algorithm for evaluating the confluent hypergeometric function.
I am also slowly working my way through Project Euler.
