Tap BPM for Teenage Engineering Pocket Operator

I have a Teenage Engineering Pocket Operator (PO-12) and it’s pretty cool. One thing I felt was missing, though, was a way to tap a button to set the BPM value - the 3 presets (Hip-Hop, Disco, Techno) and dial adjust isn’t very specific. It does however have a sync feature that allows you to connect multiple Pocket Operators together (and I’ve heard some other devices as well) - and keep them in sync… which got me thinking, could one create the sync signal using some simple electronics and programming? Project time… more→

Ubiquiti AP Setup Debugging

While trying out a Ubiquiti wifi solution, I ran into one AP not getting installed correctly. It was showing as either disconnected or pending authorization - the latter I think means that it was trying to connect to a wifi netowork rather than the ethernet network it was plugged into. more→

ES8266 / DHT22 - Wi-Fi / Temperature & Humidity server (example mashup)

Here’s a quick (couple hours with my sloppy mistakes) mashup of two Arduino examples - the ES8266 (HUZZAH from Adafruit) WiFi controller and a DHT22 temperature and humidity sensor. This is the start of a bigger project which tells outdoor and indoor temperature along with accurate time (more on that to come), and probably wind speed, etc… more→

Update to using an ATtiny85 in a Similar Way To An Adafruit Trinket - specifically to run the Adafruit Neopixel library

I’m continuing to try and ‘cheap-ify’ my per effect cost for my Halloween decorations. I ran into some issues last night trying to get an Arduino sketch that used the Adafruit Neopixel library and ran on a Trinket to run on a straight ATtiny85. The solution was to select the chip in the Arduino IDE and using an AVR programmer, burn the ‘bootloader’. more→
