futz f&ts v.i. To tinker experimentally; to change something just to see what it does

Bought an Adafruit Trinket M0 on a whim in a recent order. I thought it was going to be just yet another little Arduino type board. Boring... Turns out it is that, but it's also more, and it's pretty cool.

This isn't a new thing, but it's new to me. The board is set up out of the box to run Circui...

I'm tinkering with various cheap Chinese Bluetooth modules these days. This one is the KCX BT003 - about $3.50 Canadian. I bought mine at icstation.com, but they're available all over the interweb. This module is Bluetooth 4.2. It does MP3, WMA, WAV, and FLAC, and claims to be lossless.

This board...

On a recent China order I bought five 16F72 PIC microcontrollers in 16-SOIC for very cheap, thinking I could find some use for them. They sat in a box for a long time. Lately I've finally got somewhat caught up with work and have a little time for electronics tinkering again, so I decided to wire on...

I love my 2-wire LCDs and use them all the time, but since I started tinkering with the PIC10F322 chip that has only four I/O pins I decided to have a closer look at Roman Black's "Shift1" system. I could really use that one extra pin!

Shift1 uses a 74HC595 shift register with a couple RC circ...

I got my PC boards from OSH Park. The top boards are just some SOT23 breakouts to make breadboarding easier. Soldering wire legs onto SOT23s is a little difficult, and they don't hold up well to plugging and unplugging.

The bottom boards are my PIC10F322 general purpose board. OSH Park shorted me...
