A Few Good Reasons Why Peter Knight Rocks

Peter Knight works with Massimo and Alex and co. at Tinker.it. He’s written some great AVR code, which is useful in Arduino.  For example: Secret Thermometer takes advantage of the ATMega’s internal thermometer. Turns your ‘328-based Arduino into a thermometer … Continue reading

Physical x Wonderfl

Shigeru Kobayashi, who made Gainer and Funnel, has made yet another nifty tool for physical computing:  physical x wonderfl. It combines Gainer, Funnel, Firmata, Arduino, and Wonderfl.

Using an Accelerometer to Sense Which Way Is Up

ITP just got some nifty flat panel mounts that can rotate 360 degrees. They’re very easy to move, it takes only one hand. When I saw them, I thought, “what good is a rotating mount if the content on the … Continue reading

Sensorbase datalogger

Sensorbase.org is an open data repository run by the Center for Embedded Networked Sensing at UCLA. It’s a database of sensor databases. You can upload datasets to it, and you can browse other datasets as well. If you’ve never set … Continue reading

Random Numbers and Physical Computing

That can take up lots of processing time, so it’s usually the first function to go when writing a microprocessor language.In fact, most of what you do in programming physical computing projects is to figure out how to deal with the world’s natural randomness and make it look smooth…. Your consciousness is a great leveller for the sensors that are your eyes, ears, skin, nose, and taste buds When you move a photoresistor from one room to another, your readings will be totally different, and all of a sudden, you have to re-calculate what is "average" and what constitutes the lighting change that you want.

Sound in to a Microntroller

Microcontrollers can take sound in as an analog input, for crude measurements. While 8-bit ones  (the Basic Stamp, BX-24, PIC, Arduino, etc) are not fast enough to read the frequency difference between various sounds, they can read sound levels. A … Continue reading
