Posted on February 6, 2020 by paulwallich

I’ve been working on and off with Blinkinlabs’ BlinkyTape and pixels, which means also with their nice little app PatternPaint, which lets you create little light shows to download to their LED strands without all the annoying number-fiddling that is … Continue reading →

I’ve liked Blinkytape ever since it came out. Sure, you can hook up LED strips with an arduino or whatever easily, but sometimes having the controller built into the tape just makes things so much easier no wiring, no mounting, … Continue reading →

I am amazed that this works

Posted on December 1, 2014 by paulwallich

I knew those clip-on magnifiers were good for something other than soldering. That’s an 0603 surface mount LED, held down by wire glue. The traces are silver conductive ink, and those huge-looking red and black conductors are 22-gauge hookup wire. … Continue reading →

An unintended consequence of wire glue’s high resistance

Posted on November 16, 2014 by paulwallich
