IR comms considerations (for penlift for the Drawbot)

Introduction I was planning to hold this to be part of a much larger writeup of the Drawbot, but while it started as part of that project, it sort of took on a life of its own as an IR … Continue reading

Getting Tiny core working with Arduino 1.6.3

The first time I tried to compile for an AT Tiny84 with Arduino IDE 1.6.3, it failed with a warning and an error.  The warning was “Third-party platform.txt does not define compiler.path.”  The error was “Error while compiling: missing ‘recipe.cpp.o.pattern’ … Continue reading

Tiny85 dev/target boards

Just a quickie, but it seems to delight me.  I finally got around to making up a little bunch of generic Tiny85 boards so I can knock out some simple projects.  They’re a lot like the I2C slave boards for … Continue reading

Tiny85 ISP cable mini shield for Mega

Well that was embarrassing.  I thought I could knock out a quick mini-shield for an Arduino Mega to use as a programmer for Tiny85s (or most any other AVR chip).   I did, and it works, but only after two iterations … Continue reading

Dollhouse net with ATtiny85s

(This is one of a pair of unrelated Tiny projects that seem to be going on in parallel.  I don’t think I could have chosen two more confusable projects if I’d tried.) These are the first steps in implementing a … Continue reading

Oops

While working on stuff for the upcoming Tiny85 class, I accidentally plugged one in backwards.  After I heard the little “poof” I unplugged it and tried to pry the chip out before I realized it had gotten hot enough that … Continue reading

Tiny85 fuse resetter

The AT Tiny85 is a great, cheap ($1.29 qty 1 at  Digikey!) little processor.  At 8 pins, little is the operative word.  Assuming you don’t need an external crystal (a good assumption for 99% of the hobbyist use cases of … Continue reading
