Things are different. In the 2+ years after I gave up on making things for a living a lot of things have changed. Things on my personal radar…. The price points for adding wifi for Q<1000 is not $15. It’s $3. The Midi Manufacturers Association finally put 3.3v into the hardware standard. The Non compete… Read more »

Things are Different In 2012 I was struggling to put together a stm32 based wireless datalogger using leaflabs libmaple and a $20 wifi module. I had to write most of the code myself because libmaple was based on arduino-0022 and most of the wifi libraries made extensive use of the new classes available after… Read more »
Background. I was asked to put together a 2 day class on the internet of things at PNCA so I suggested that we try out the Adafruit huzzah. while I was looking for it I came across the Sparkfun Esp8266 “thing” and the Esp8266 dev board. I used the Sparkfun Esp8266 dev board to implement a… Read more »
/* Ping))) Sensor This sketch reads a PING))) ultrasonic rangefinder and returns the distance to the closest object in range. To do this, it sends a pulse to the sensor to initiate a reading, then listens for a pulse to return. The length of the returning pulse is proportional to the distance of the object… Read more »
melodyDetector-140809-James Here’s my updated code.
It would be great if we could have a little group show at PNCA. I could bring this piece and the last class project.
neopixel_fadeUpDown_sketch_jul24b-140724aIn progress for NeoPixels
Here’s my code for the arduino sketch and pure data so far. Works ok in really quiet environments if you play the song a two or three times. Would like to filter the data better to make it more accurate and perform better in environments with regular low-level noises going on. Also does anyone knows… Read more »
I made a mock-up in Max for LED control. Here’s a screenshot. LED-Mockup-Max I’m porting it to PD but in the meantime I am starting to work with Neopixel strips from AdaFruit and they have built in libraries for Arduino, so I will probably put this PD port on hold until I figure out which… Read more »
