Audible DIScontinuity tester
Sometimes I’m trying to check a cable – often a thin audio coax – for an intermittent open. I could hook an audible continuity tester to it and listen for the noise to stop momentarily, but a less annoying and … Continue reading

Hot melt glue gun timer
I use hot melt glue a lot, but the warmup time is a problem. I turn the gun on, go away to do something else while it warms up, and may or may not remember the pending glue job. I’ve … Continue reading
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
Quickie 1-cell discharger
Wow – I wasn’t planning to make this. But as I fantasized about just building a simple discharger while struggling with 1-cell problem on the big 18 cell discharge tester, it sounded too simple to resist. I could get to … 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

Tiny85 class
I finished the second run of the Tiny85 class Saturday (1/25/14). It was pretty good, but as before | always there was room for improvement. I’ve been using Freemind for the official repository of ideas, todo lists, lesson plan etc, … 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
