Tom Igoe, author of Making Things Talk, is in the rainforest in eastern Ecuador, applying his sensor and embedded hacking skills to tracking monkeys (from Part 4 of his adventure postings): This morning, Kevin and Tony and I went to look for titi monkeys. We didn’t find any, but we did manage to get lost, […]
Thermistors are pretty cool little items. They convert heat into resistance. By having the temperature available as resistance, you can use the value to control other things like circuits and programs. Photo cells do the same thing with light, and they are in lots of common devices from night lights to dimmers on clock radios. […]
Dave Prochnow writes on PopSci: Every AVR programmer worth her weight in ATmegas knows about the AVR Butterfly–a ridiculously low cost ATmega169 demonstration and evaluation kit. Lamenting the lack of such a kit for the ATmega168 drove me to design my own demo/eval kit for the Arduino microcontroller family. This project became a compulsion that […]

Using a chip that’s sort of an Arduino times 4, the Reprap team has a new prototype motherboard. Via hackaday: When the RepRap team found themselves pushing the limits of the Arduino, they started looking for alternatives. They found it in the ATMega644P. It has four times the memory and four times the RAM compared […]
I just published my Instructable on getting my Arduino to take care of my plants. Specifically, Garduino waters the plants when their soil resistance level drops too low and turns on supplemental lighting to make total light daily equal 16 hours regardless of outside conditions. It’s not pretty, but it works! Other than de-uglification, let […]
Want to make your own Arduino shields? Garrett at Macetech has an Eagle file to make your life a little easier: I created a very basic Arduino shield scaffold; the schematic has only the standard Arduino headers, and the PCB has the correct header spacing and labels. The PCB headers are locked so they can’t […]
