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

After getting my clock code to the stage it was at in Part 2, I started to refine the code and add features. That code was pretty quick and dirty. It worked, but still needed lots of work.

I started looking at actual i2c timings. I had built my clock code by just picking a random number (100uS) th...

After not looking at electronics for quite a while, and PICs for even longer, I started a project with the PIC16F72 board and soon found out why those savage old chips were being sold from China for cheap. I ran out of memory right quick. Could have probably done it if I switched to assembly langu...

Long time since last post. Other hobbies get in the way, and in my tiny house my electronics bench gets buried.

I bought a Wemos D1 Mini with MicroPython as part of a toy order from universal-solder.ca. Universal Solder is a Canadian company, which I like to support. They have a pretty good sele...

I wrote some code for the PyBoard to drive a TM1637 4-digit 7-segment LED display. The code is basically I2C with no slave, so not terribly difficult to bit-bang.

Then I modified that code to use the PyBoard's RTC to work as a clock. That worked fine, so I thought I would get it going on the Trink...

I've been interfacing the pyboard to all kinds of stuff to get a bunch of coding and practice under my belt before I really try to do something like a robot with it. I've ported my 5110 LCD C code for PIC to MicroPython, and connected things like servos, a HY-SRF05 ultrasonic range sensor, a Sharp G...
